Medicinal Honey

Medicinal Honey

Exploring Manuka Honey & Jelly Bush Honey for Health

The therapeutic use of honey can be traced as far back as early Egyptian civilizations. Despite this long traditional use, it was not until the twentieth century that honey proved its worth in scientific trials. In the past 100 years countless studies have shown manuka honey and other medicinal honeys to offer an effective treatment of coughs, sore throats, burns, wounds and ulceration with far less side effects than other topical treatments such as silver sulfadiazine.

Honey & Coughs

Honey has also been found to be equally effective as cough medicines for soothing coughs. This research paper highlights that most prescribed and over-the-counter preparations for cough in children are not effective and might carry the risk of adverse events. A single dose of honey before bedtime was shown to diminish cough and the discomfort experienced by children and their parents. And only regular honey was used in this study, so we can imagine that medicinal honey would be even better!

Honey & Wounds

Honey’s wound healing properties are attributed to osmolarity, pH, hydrogen peroxide production and nutrient content. The high osmolarity of honey draws excess fluid from the wound helping relieve inflammation. pH refers to the level of acidity and alkalinity of an environment. The low pH of honey creates an acidic environment that reduces bacterial growth and stimulates wound healing. These factors work synergistically in creating a favourable environment in the wound bed during the early stages of healing.

Manuka Honey

Not all honey is created equal.  Manuka honey comes from flower nectar of the manuka bush Leptospermum scoparium, a plant indigenous to New Zealand. Although all honey possesses generalised antibacterial activity, Manuka honey is a cut above. These unique antibacterial and antifungal properties, discovered by researchers in 1981, is what sets this honey apart from the rest. New Zealand native bees do not produce honey, however, the European honey bee was introduced to New Zealand and became the source of local medicinal honeys.

Jelly Bush Honey

Australian Jelly Bush honey also possesses similar antibacterial properties to Manuka honey. The Jelly Bush or Golden Tea Tree plant, Leptospermum polygalifolium, grows in certain areas of the coast between Kempsey and Bribie Island as well as in Far North Queensland. Tasting a lot like paperbark honey, with a strong malt taste, Jelly Bush honey is only produced in the spring when the coastal heath explodes into a shower of tiny flowers that the local bees love. Some say that Australian Jelly Bush does not crystallise as readily like its competition across the Tasman, making it superior for skin wounds that refuse to heal. The Australian Aborigines have a long history of using native bees - harvesting both honey, pollen and wax for many applications. See this article for more info.

How Medicinal Honey Works

The chemical compounds hydrogen peroxide, methylglyoxal and dihydroxyacetone give active honeys their antibacterial power. These compounds, also known as the Unique Manuka Factor (UMF) is what Manuka honey is graded on. So far researchers world wide have not been able to identify all the exact compounds in the plant that the bees harvest and are specifically responsible for the efficacy of the active honey.

Methylglyoxal (MGO) has been shown to be effective against the following bacteria infamous for causing skin infections, leg ulcers and peptic ulcers:

  • Staphylococcus aureus
  • Methicillin resistant Staphylococcus aureus
  • Psuedomonas aeurginosa
  • Proteus mirabilis
  • Enterobacter cloacae
  • Helicobacter pylori

 

Grading System

Most manuka honeys use the UMF grading system. This grading system was set up by the UMF Honey Association of New Zealand (UMFHA) to ensure industry standards.  Another standard commonly referenced is the MGO level or methylglyoxal content.

Below is a conversion chart to help understand the two systems:

Image courtesy of Comvita (2018)

Active Honey Doesn’t Come Cheap!

The price of manuka honey is dependent upon the UMF or MGO rating. A higher rating denotes that the honey has a greater therapeutic effect and therefore a higher price. Because there are two grading systems, it is easy to get confused between what each means. UMF is largely thought of as the better grading system because it not only takes into account the methylglyoxal content but also the hydrogen peroxide and dioxyacetone levels. In a nutshell the higher the number, the better the honey. Active honey can range in price from $20 to $80 for a 250g jar – depending on its activity rating. I stock the Active Jelly Bush Honey in my Buderim clinic for $35 for UMF 15.

So while we need to be mindful of consuming too much sugar and honey is no different, active honeys from Manuka or Jelly Bush offer health benefits as well as a sweet taste.  Using these honeys topically on wounds, for inflammation and for a local antiseptic action on sore throats or for coughs is a great way of getting a simple natural remedy we can use at home!

 

 

Paleo Muesli

Natural Muesli Recipes

for Busy Mornings

Popping some muesli and yoghurt in a jar can give you a healthy breakfast to go for those busy mornings!

It is important to start your day the right way with a decent amount of protein, fats and fibre. Sometimes our busy lifestyles prevent us from chowing down on a serving of eggs and veg, and ironically these more stressful times are the periods we need these food groups the most. Often when our busy lives prevail we reach for a less-healthy, more convenient breakfast food like cereal.

Muesli, like all cereals, should be thought of as an occasional alternative to a more protein rich breakfast. We can also get sick of having eggs every morning and sometimes we just need a bit of variety. While many cereals are loaded with unnecessary sugars, when we make our own wholeseome muesli we can be more in control of the fuel we give our body on those busy mornings when we need it most. Here are two recipes that you can try:

 

Toasted Oat, Macadamia & Cranberry Muesli Recipe

Why it’s good

Oats are a good source of B-complex vitamins, protein, amino acids and minerals such as calcium, potassium, phosphorous, manganese, zinc and iron. As well as being a valuable source of these nutrients, oats contain a soluble fiber called beta-glucan, to which most of the food’s health benefits are owed:

  • Beta-glucans increase bile acid synthesis that inadvertently decrease blood serum cholesterol
  • Being a soluble fiber, beta-glucans slow stomach emptying thereby reducing the rise of blood glucose following a meal

Cranberries outrank many other common fruits and vegetables in antioxidants, with an antioxidant (ORAC) score of 8,983 per cup of whole cranberries. See this article for a discussion of the ORAC score and antioxidant ratings for many superfoods.

What further sets cranberry apart from others in the fruit family is it’s high content of A-type-proanthocyanidins, a more biologically stable counterpart of B-type-proanthocyanidins found in other fruits.

Coconut is a good source of copper, manganese, selenium, iron and potassium as well as being high in lauric acid, an essential saturated fatty acid that promotes HDL (the good cholesterol) and also weight loss.

Macadamia nuts are high in monounsaturated fats, which have been shown to improve blood lipid profiles and reduce the risk of cardiovascular disease and stroke.

 

Ingredients: What you need
  • 2 cups of rolled oats
  • ½ cup of dried cranberries
  • 1 cup of shredded coconut
  • ½ cup of macadamias (raw or roasted)
  • ½ cup of sunflower seeds
  • ½ cup of pepitas

*This recipe makes enough for about seven servings

Method: What to do

Toast oats in oven, spread out on a tray until they develop a slight golden colour

Chop cranberries and macadamias roughly

Combine all other ingredients with oats, macadamias and cranberries

Serve up a bowl and enjoy your delicious yet nutritious muesli with your choice or milk or yoghurt and fresh fruit if desired.

 

Paleo Alternative

Why it’s good

Walnuts contain almost double the antioxidants compared to other nuts such as almonds and pistachios. They also contain the omega 3 fatty acids EPA and DHA. EPA is renowned for its protective effects in the cardiovascular system whereas DHA is important in brain and eye health.  

Pecans, like other nuts, contain a plethora of healthy fats and minerals. Contrary to popular belief these fats actually improve weight loss and reduce weight gain. This is because eating a diet high in healthy fats (and low in carbohydrates) helps our body switch from burning sugar to burning fat for energy. An additional benefit of these fats is that we stay fuller for longer as these fats suppress the ‘hunger hormone’ ghrelin.

Cacao powder, the unrefined brother of cocoa, is a good source of magnesium and antioxidants but still provides the chocolate hit we all crave. Recent studies have shown cacao to improve pancreatic beta-cell functioning (the cells responsible for producing insulin). Increasing cacao (while limiting sugar) may improve blood glucose levels and reduce your risk of developing type II diabetes.

 

Ingredients: What you need
  • 1 cup of chopped raw walnuts
  • 1 cup of chopped raw pecans
  • 1 cup of shredded coconut
  • ½ cup of macadamias
  • ½ cup of sunflower seeds
  • ½ cup of pepitas
  • 1 tablespoon of maple syrup, rice malt syrup or honey
  • 1 tablespoon of coconut oil
  • 2 tablespoons of cacao powder

*This recipe makes enough for 7 servings

Method: What to do

Mix ingredients together. It can be easier to mix the coconut oil, syrup and cacao powder together first before mixing it with the nuts and seeds. Spread onto a baking tray.

Toast muesli in oven on a low-medium setting for 10 minutes, stirring half way through to ensure even toasting.

Serve up a bowl and enjoy your delicious yet nutritious muesli with your choice of milk or yoghurt and a few mixed berries if desired.

Herbal Tea as Medicine

Herbal Tea as Medicine

As we head into the cooler months, a warm cup of tea in our hands can be a real blessing. But aside from being a tasty beverage, herbal teas can also be a great way of getting our medicine. Plants contain all sorts of phytochemicals, antioxidants, minerals and vitamins that are good for us in a general sense as well as having more specific actions on certain systems of the body.

 

History of Herbal Teas

Before the advent of modern manufacturing processes and herbs coming to us in tablets or brown bottles, herbal tea was the major way herbs were delivered as medicines. In many cultures around the world, households kept some basic dried herbs in the cupboard for simple ailments and this 'folk medicine' was passed down from generation to generation. Herbalists were often midwives or lay healers and often also in charge of spiritual matters in their communities. During the middle ages however, there was a push from the Church to gain more power and the practice of herbal medicine and healing was forbidden and many herbalists were persecuted and much knowledge was lost.  Over the past couple of hundred years, modern medicine has slowly gained power and prestige and despite many modern drugs coming from plants, herbs have lost much of their place and respect in the world of medicine. Despite this, the World Health Organisation (WHO) still classifies herbal medicine as an important, effective and viable medicine for most of the world's people who have limited access to modern pharmaceutical medicines.

Bringing Back Herbs to the Household!

Many of us use both fresh and dried herbs in our cooking - and this is a simple form of food as medicine. But having a range of simple herbal remedies as teas in the cupboard is still a good way to care for yourself and your family for basic common health complaints. While herbs do not offer a replacement for modern drugs in every condition, having some basic knowledge and remedies on hand can give you other options and alternatives to mainstream approaches for simple complaints such as colds, coughs, digestive disorders, stress and sleep issues. Herbal teas are also great for children as they provide a gentle and safe option that is effective but without the side effects of some modern medicines.

Herbal Tea as Medicine

There are two main methods to make a medicinal tea - using dried or fresh herbs and boiling water. Plants contain different constituents in different parts of the plant - active parts can be found in the roots, the bark, the leaves, the berries, the flowers. Some constituents are easily dissolved in water, while others are not. Thus the preparation method employed in making a herbal medicine is important - and the best method will make it most potent and effective.

Infusion

An infusion is what we usually think of when we think of making a tea. Simply pouring about 1 cup boiling water over 1-2 teaspoons of dried herbs is how to make a basic herbal tea infusion. Infusions are best for leaves and flowers that are more delicate and yield their active constituents easily in boiling water - and ones that contain essential oils are readily captured and not destroyed by simple infusions.

Fresh plant infusions are also possible with fragrant herbs like lemon grass, mint, lemon myrtle, lemon balm and they tend to be milder in taste and concentration. With fresh plant material, we tend to use a bigger volume as it already has a lot of moisture content. Chop or crush a decent handful of fresh herbs per cup of boiling water.

Decoction

​​​​​​​Decoctions are when herbs are simmered over low heat over a period of time (usually for at least 5-10 mins) to extract more of the constituents. Decoctions are best employed with woody stems, barks and roots that need a longer processing time to release their medicinal actives. There are some herbs that teas or decoctions are not suitable for, as the active products are not readily extracted in water. Alcohol is a better solvent in this regard - such as for certain resins and gums.

 

Cleansing tea - great for detoxing!

I have created different herbal blends that I make up from organic high quality herbal teas as well as some single teas. These teas offer tasty and effective medicine or a range of common conditions:
  • Lung and Cough Tea
  • Relaxation Blend
  • Digestive Blend
  • Cleansing Tea Blend
  • Lactation Tea
  • Peppermint or Spearmint
  • Raspberry leaf
  • Dandelion root or leaf
  • Nettle leaf

 

So next time your in the clinic, go grab a pack of herb tea - you will find it is vastly different from the tea bags you get at the supermarket and it will offer you a simple home remedy too!  I can also post teas out to you - details and purchase options can be found here.

 

 

 

 

protein powders

Your Guide to Protein Powders

Protein powders - how to choose the right one for you!

Protein is an important component of practically all structures and functions of our body. Protein is needed for energy production, to build and retain muscle, to support liver detoxification and regulate our moods and thinking.

We need approximately 0.8 grams of protein per kilogram of body weight - assuming a normal weight. However, many of us don’t get sufficient protein, due to busy lives and meals not being well balanced day in and day out. Also factors such as ageing and stress can impact our ability to digest protein, placing an additional burden on our already overloaded systems. Likewise, too much protein is also detrimental on our body and in particular burdens the liver and kidneys, so it is important to aim to get the right amount each day.

While consuming a variety of whole food based proteins from animal products or by combining vegetarian sources is the best way to get protein, the use of protein powders has become a popular way of boosting our daily protein intake. The protein powder market is becoming more and more saturated by the day, so choosing the right protein for your individual needs can be tricky.  Shortly we will look at the different types of protein powder and uncover the pros and cons of each one.  But firstly it is a good idea to have some background info on amino acids to be able to understand and compare different types of protein powders.

Amino Acids

Amino acids are the building blocks of protein. While some amino acids are needed from the foods we eat, our body is capable of making other amino acids. This is why amino acids are divided into two groups: The essential amino acids; those that we can’t create, and the non-essential amino acids; those that we can.
aminoacids

 

Most good quality protein powders contain all of the essential amino acids and additional non-essential amino acids alanine, arginine, asparagine (or aspartic acid), cysteine, glutamine (or glutamic acid), glycine, proline, serine and tyrosine. If a vegetarian based protein works best for you I would recommend combining rice and pea proteins to ensure you are getting all essential and most non essential amino acids.

Branched Chain Amino Acids

Branched chain amino acids (BCAA’s) are concentrated in muscle tissue and used to fuel working muscles. The content of BCAA’s in protein powder is therefore an important factor to consider when choosing one that is right for you. The BCAA’s isoleucine, leucine and valine are highest in whey-based protein powders (24%) followed by soy (22%) and then brown rice (18%).

Ratio of Amino Acids - Lysine to Arginine

The herpes virus (cold sores) can be reduced by the amino acid lysine.

Lysine and arginine are competing amino acids within the body. Oftentimes our diets are replete in arginine and lacking in lysine. Lysine is needed for the formation of immune molecules known as immunoglobulins. If the arginine to lysine balance is thrown out the formation of immunoglobulins is reduced. Arginine is also needed by viruses to be able to reproduce so having adequate lysine stores helps to prevent this from occurring. When the ratio of lysine to arginine is thrown out our body becomes more susceptible to opportunistic and dormant infections.  Reoccurring cold sores (herpes virus) are an example of this. When choosing a protein powder it is important to look for a ratio of 3:2 of arginine to lysine. Some people can find that a protein powder that is too high in arginine may result in an outbreak of cold sores or other infections.

 

Whey Protein

Contains 70%-80% protein and up to 5% lactose. Whey protein is rapidly digested making it a preferred source of protein for athletes however the lactose content may cause gastrointestinal discomfort in those with lactose intolerance. It is important to note that the 5% lactose content found in whey protein is slightly higher than what is normally found in other dairy products. If gastrointestinal symptoms occur after whey protein it is probably best to change powders or consider swapping cows milk to a dairy free alternative as having a whey based protein with cows milk compounds the lactose. Whey protein contains more isoleucine, leucine (branched chain amino acids), lysine and threonine than other non-animal sources of protein. I stock a great grass fed whey powder that is affordable and effective.

 

Brown rice is used to make protein powder

Brown rice is used to make protein powder

Brown Rice Protein

Brown rice protein powders contain approximately 78% protein. Despite its lower protein content, a recent study found there to be no difference in post workout recovery or soreness between brown rice protein and whey protein. Brown rice protein has more phenylalanine (a precursor of our feel good hormone dopamine) compared to whey based protein powders, and more valine and methionine compared to soy based proteins.

Pea Protein

Pea based powders contain about 73% protein. As peas are considered a fructooligosaccharide and are highly fermentable by our gut bacteria, pea protein should be avoided in cases of irritable bowel or small intestinal bacterial overgrowth (SIBO). Pea protein contains more lysine than brown rice protein. As we learned above, the amino acid lysine improves immune system function but is also stimulates intestinal absorption of calcium, and is required for collagen synthesis. Lysine is particularly important in vegetarians and vegans, as it is commonly deficient.

Soy Protein

Soy protein concentrate is made from soy flour with the water-soluble carbohydrates and fat removed and typically contains about 70% protein. Soy protein isolate is made from the same process only taken a step further resulting in almost 90% pure protein. Soy protein powders are generally low in sulfur-containing amino acids (methionine and cysteine) but high in branched chain amino acids. Soy protein also contains phyto-oestrogens that are essentially plant compounds that mimic the effect oestrogen has on the body. It is best to consult your practitioner as to whether consuming foods containing phyto-oestrogens on a regular basis would be appropriate for you as certain hormonal conditions can benefit from the use of phytoestrogens – but not in all cases.  A component in soy is also considered to be goitrogenic and therefore is best avoided in people with hypothyroidism. An additional factor to consider when choosing a soy-based protein is the origin of the soy plant. The majority of soy in most western societies is now genetically modified (GM).  I believe it is best to avoid non-organic soy foods as there are some serious concerns being raised in new studies on GM foods.

 

Collagen
Collagen is necessary for healthy skin and hair and also contributes to joints, nails and bone strength.

Collagen is necessary for healthy skin and hair and also contributes to joints, nails and bone strength.

Collagen is the main structural protein found in our skin, ligaments, tendons and other connective tissues. Collagen can be divided into three subcategories, all with varying roles.

Type I collagen comprises 90% of all the collagen in our body and is needed for healthy skin, hair, nails, organs, bones and ligaments.

Type II collagen is primarily found in the articular and hyaline cartilage and is needed for joint health. Type II collagen is often supplemented in either its hydrolyzed or un-denatured forms. Un-denatured type II collagen is not generally found in protein powders and instead is usually found in supplements targeting joint support. About 40 milligrams or more of collagen has been shown to be beneficial in osteoarthritis and rheumatoid arthritis.

Type III collagen is found in skin, lung and heart tissue. Supplementation of this type of collagen usually occurs in combination with type I in the form of hydrolyzed collagen. Hydrolyzed collagen is used for generalised skin and joint health, while un-denatured collagen is more specific for arthritic conditions. About 10 grams of hydrolyzed collagen is usually put in protein powders and is listed under collagen hydrolysate, hydrolyzed gelatin or collagen peptides.

Standalone collagen powders are also available usually in type I or a combination of type I and III. Collagen, being a protein itself, is often used to boost protein intake, and aid tissue recovery and repair. Five grams (1 teaspoon) of collagen hydrolysate is a decent dose of collagen as a standalone powder.

Bone Broth

brothIn addition to supplemental forms, collagen intake can also be increased through foods. Bone broth is a wonderfully nutritive and restorative way of using food as medicine to improve collagen stores. For more on the benefits of bone broth and a link to my recipe click here.

Sources of Collagen

  • Piscine (fish)
    • PROS: Collagen proteins from fish are considered superior in raising overall body collagen (Type 1) and improving skin, hair, nail, and bone quality (Shiratsuchi et al. 2010)
    • CONS: Fish collagen peptides generally cost more than other sources of collagen
  • Bovine (cow)*
    • PROS: Bovine collagen peptides are usually lower cost, and comprise a wide array of collagen supplements on the market due to the high accessibility of bovine materials
    • CONS: Not considered as effective as fish collagen peptides in raising overall body collagen levels
  • Porcine (pig)*
    • PROS: Like bovine products, pig collagen peptides are usually lower cost, and comprise a wide array of collagen supplements on the market due to the high accessibility of porcine materials
    • CONS: Not considered as effective as fish collagen peptides in raising overall body collagen levels
  • Fowl (chicken)*
    • PROS: Chicken collagen peptides are known to be most effective for supporting cartilage in the body. For this reason, type II collagen supplements are usually derived from chicken
    • CONS: Not considered effective at raising overall body collagen levels

*Collagen from grazing animals such as bovine and pig should be sourced from grass-fed only animals. Collagen from chicken is typically not as common as the other sources, if you are wanting to supplement using a chicken based collagen make sure the chickens were free range and raised on hormone-free feed.

I have been using a grass fed beef bone based collagen and find it to be very good, so have now started stocking it in my Buderim clinic.

Sugars, Sweeteners and Carbohydrates

stev

Stevia rebaudiana - a naturally sweet leaf!

Protein powders usually rely on low calorie sweeteners to improve palatability. While reducing sugar and carbohydrates is important in weight loss and muscle building, certain sweeteners can also cause unwanted effects. It is best (and often more affordable) to use plain protein powders and then sweeten them yourself to your own taste with berries, banana, cacao powder and natural sweetener such as honey or maple syrup or you can use the low calorie herbal based ones. The popular natural plant based ones include stevia sourced from the Stevia rebaudiana plant or thaumatin which is a protein that comes from West African Katemfe fruit.

Sweeteners to avoid include:
  • Aspartame: Linked to increase oxidative stress in the brain and shown to impair memory.
  • Sucralose: Shown to alter how our bodies metabolise sugar and was found to be linked to leukaemia in a mice study.
  • Acesulfame K: Linked to thyroid dysfunction and metabolism disorders in animal studies
  • Saccharin: Potentially carcinogenic
  • Xylitol / Sorbitol: Often used in gum and oral hygiene products to reduce oral bacteria however use of this sweetener is also associated with gut symptoms such as bloating, gas, cramping and diarrhoea.

When it comes to sweeteners, the natural low calorie type is the better option -  examples of these include thaumatin and stevia. A problem with artificial and low-calorie sweeteners in general is that our body is too intelligent to be tricked. It is in our DNA to seek out high calorie foods for survival, and although our taste buds associate sweetness with higher calories, studies have shown that the consumption of artificial sweeteners does little to quell our overall sugar intake.

Quick Reference Checklist For Choosing Good Protein Powder
  • Aim for 6 grams of branched chain amino acids per serve
  • All essential amino acids with the additional amino acids alanine, arginine, asparagine (or aspartic acid), cysteine, glutamine (or glutamic acid), glycine, proline, serine and tyrosine
  • Protein from a preferably organic grass-fed (for bovine and porcine) and pasture raised/hormone free (for chicken) source
  • A lysine to arginine ratio of 2:3
  • 10 grams of hydrolyzed collagen (listed under collagen hydrolysate, hydrolyzed gelatin or collagen peptides)
  • No artificial sweeteners (aspartame, sucralose, acesulfame K, saccharin or xylitol / sorbitol)

 

If you would like to source a good protein powder, I can supply grass fed whey or collagen based protein and can order in a pea or rice based one for vegetarian/vegan diets. Please be in touch for more information or to purchase some protein powder.

chewing and brain function

Chewing and Brain Function

A Broad Impact on Health

carrotWho would have thought that the action of chewing food had a role other than to start the digestion process! Increasing research studies have found that mastication (technical term for the the action of chewing food) has a major impact on many aspects of our health. Chewing and brain function effects have been found in connection to learning, memory, focus and concentration.

Raw fruit and vegetables, nuts and seeds and meat all demand more chewing. Many processed foods and cooked foods are softer and easier to chew through.  One of my pet hates when it comes to commercial food products are those ridiculous pouches of soft pureed fruit that kids consume direct from a tube, instead of chewing through an apple or orange! Now we know that this will have a negative impact on their brain, memory and learning.

On average, it is estimated that we chew 800 to 1,400 times a day.  We generally recommend chewing our food slowly, at least around 15 times, but for many foods we don't need that long and realistically swallowing is in an instinctive behaviour. We simply know when food is chewed well enough and then we naturally swallow. While it may seem logical that easy to digest food is a good thing, in reality we haven't evolved with soft foods. Many of the pathways that stimulate digestive juices and gut motility (that are essential for digestion) stem from the action of chewing and the taste of foods. Bitter foods for example are highly stimulating for digestion and chewing sends signals to the brain that stimulate the gut to prepare for food.

Good Teeth Are The Key!

elderlyAs we age, many people have declining memory and focus and concurrently may also suffer from poor dental function. With bad teeth, elderly people often resort to soft foods that don't tax the teeth, however this may lead to unexpected negative consequences. Not only will the gut not get clear signals for digestive juice manufacture, we now know there are more broad problems that can arise in distant regions of the body.  In particular, we know that mastication has a direct impact on learning and memory formation and so poor dental health can impact the brain. For instance, research has shown that the systemic effects of tooth loss are a risk factor for Alzheimer’s disease.

The hippocampus is the brain region that is involved with forming memories and it seems that the action of mastication, stimulates this area. Functional MRI studies can compare the difference in brain region activity in different populations. The acquisition of memory in elderly people was significantly enhanced by chewing, but benefits of chewing had less effects in younger people.

Interestingly, another study found that lower intakes of nutrient-dense foods and higher intakes of unhealthy foods were also both independently associated with smaller left hippocampal volume. So it seems that it is both the processed foods being both nutrient poor and requiring less chewing that create a perfect storm for brain impairments.

Researchers have also found that a reduction in corticosterone production is another way that mastication can have a role in poor brain function. Thus a chronic stress state is induced by poor chewing activity and this can in turn lead to learning and memory impairments.  Concurrently, the act of chewing during stressful conditions was shown to attenuate the effects of stress on cognitive function. This has been further explored by some researchers with a recommendation to chew gum as a way of enhancing memory and cognition and delaying the development of dementia and also ameliorate the effects of stress on the brain.

appleSo there are so many reasons to chew your food well, and make sure the foods you eat include some types that require lots of chewing - like raw veggies! Also, it serves that foundational to this whole approach is to also ensure optimal dental hygiene. So if you choose to chew gum to boost your memory, make sure it is sugar free or contains xylitol which has been shown to reduce oral bacteria and prevent gum disease.

Fever

Natural Fever Management

fever thermometerI see many children in my practice with recurrent infections and lowered immunity. In these cases, I always check in with the parent about their usual routine for fever management. So many parents are scared of fevers and I spend a large part of the consultation educating about the importance of fevers, their role in immunity and how to manage them more naturally.  It is not uncommon for parents to give multiple doses of paracetamol or ibuprofen containing medicines to lower a fever. While every parent is well meaning and wants to ease discomfort in their child, these drugs are not without side effects. Many children overdose from excess paracetamol ingestion and it is the leading cause of paediatric hospital admissions and calls to poisons information hotlines.  Children aged between 1-3 years old have the highest incidence of accidental poisoning.

Why Do Fevers Occur?

coldFevers are a common occurrence in children and less common in adults possibly due to a child's immune system being more immature and many adults tend to suppress the fever response over the years and have a generally lower vitality. The most important thing to know is that fevers are not a disease but rather a symptom of another disease process. The body uses a fever to stimulate and enhance the immune system to deal with the actual disease process. A fever may occur in response to many different challenges that the body faces, including infections, burns, dehydration, heatstroke, vaccination, drug and alcohol use, excessive exertion and exhaustion. In babies and young children fevers can also accompany teething, overdressing and overexcitement. Most fevers that occur are the result of a viral infection and are considered a natural defence mechanism employed by the immune system.  Research has revealed that the raising of core body temperature destroys many viruses and bacteria which can only survive in a narrow temperature range. Fevers also enhance immunity through increasing white cell counts.

The thermoregulation of the body (temperature control mechanism) is a finely regulated process. While many people get alarmed that the body temperature is elevating and might not stop, it is important to understand that the fever process is finely regulated by the brain. The hypothalamus (brain region) acts like a thermostat and responds to substances in the body and can increase or decrease temperature states.  These substances called pyrogens are produced by the body but are also produced by infectious agents such as viruses and other pathogens. In most cases though the temperature rises to 39-40.5 and stops. In very rare cases, if the core temperature stays elevated for too long at a very high temperature above 41 degrees C, it is possible for the fever to cause damage to tissue and impair cell function.

But what about febrile convulsions – aren’t they dangerous?

brainThe fear of a febrile convulsion is certainly what drives many parents to turn to paracetamol or ibuprofen during a fever. A febrile convulsion or mini seizure normally occurs when the body temperature rises too rapidly and contrary to popular thinking is not due to how high the temperature is per se.  A febrile convulsion generally only lasts one to two minutes but can last up to 10-15 minutes. The actual risk of febrile convulsion is actually very low, only occuring in approximately 3% of children. These convulsions, while being stressful to witness, are actually benign, do not damage the brain or impair intelligence. There is no long term complications or increased risk of epilepsy or other seizures following a febrile convulsions. Research has shown that paracetamol does not decrease the risk of febrile convulsions. It is possible that as the medicines wear off, there can be a more rapid rise in temperature as the body attempts to increase the fever response and that might be a possible trigger for seizures.

Feed a Cold, Starve a Fever?

sick childLike many ‘old wive’s tales’ there is truth in this saying. When we eat while having a fever it diverts energy away from the vital response and can decrease our ability to fight the illness. In addition, it is possible that the body may misinterpret food substances absorbed from the gut as allergens during a fever response as it is on high alert. In most cases of fever, our body ensures we don’t eat too much anyway, as our appetite is often very low and we don’t feel like eating.  However, it is very important to remain well hydrated during a fever as the increased body temperature and sweating can lead to dehydration. Small frequent drinks of water and medicinal herbal teas are best initially in the early stages and then you can use bone or vegetable broth or diluted vegetable juices once on the mend.

It is normal for a fever to increase the heart rate and be accompanied by other symptoms such as a headache. Remember that when using paracetamol or ibuprofen to relieve a headache or lower the fever might make your child more comfortable, it will also make their body work harder to fight the infection. So instead of trying to bring a fever down, consider allowing it to do its job. I find in most incidences when a fever is allowed to run its natural course the patient

dispensaryrecovers much quicker. I have also found that in cases of chronic lowered immunity and recurrent infections, allowing a fever to run its course has an immune enhancing effect that boosts the vitality and helps to prevent another infection – effectively breaking the cycle of recurrent infections. There are some remedies that you can use during a fever to alleviate some of the unpleasant side effects but still support your body. I find homeopathic remedies can be effective and some herbal teas are useful.  Supporting your body with vitamins can also be a good way to enhance the immune response without lowering the fever.

Natural Fever Management Tips

When dealing with a fever, you should aim to support yourself or your child by staying warm, keeping well hydrated and getting plenty of rest.  The onset of sweating will often resolve the fever, but do not force your child to be over dressed or covered to stimulate this.  As a general rule, if you or your child is still shivering or has cold hands or feet, do not attempt to lower the temperature as the body is still raising the temperature to the optimal level.  Wait until the body is universally hot or sweating has started, as this heralds the climax of temperature. The body will naturally bring the temperature down when it deems that the time is right.

RED FLAG : redflag
  • While most fevers can be managed safely at home, always seek medical advice when fevers are accompanied by other major or severe symptoms such as persistent cough, vomiting, headache with neck stiffness, respiratory distress or marked mood disturbance or when fevers are very high and continue for more than 24-48 hours.

 

 

Summary of Tips For Managing Fever and Keeping Hydrated
  • Offer plenty of water or rehydrating formulas but avoid using juice or milk as hydrating agents

broth

  • Use homemade bone broth or vegetable broths / soups once on the mend. Recipe is available here.
  • Herbal teas such as rosehip, yarrow, elderflower & peppermint can help with fever and cold symptoms.

homoeopathy

  • Homoeopathics such as Belladonna, Aconite are great for sudden onset fevers.
  • Tepid baths and sponging can make children more comfortable and will help to lower the fever a little if you feel it needs to.
  • Make sure  you or your child child gets plenty of rest and sleep!

 

 

 

 

Harmful Effects of Screen Time

Harmful Effects of Screen Time

Kids and Media Use:  How Much is Too Much?

School holidays are fast approaching again! Many parents (and kids!) look forward to less routine, no school lunches and rushed mornings! Hopefully the spring weather will draw kids outside to play in nature and at the beach - but many children I see in my clinic tend to spend their holidays stuck behind screens. Without the 'school night' curfews, often it is a free for all when it comes to kids and screen time during holidays.

So are screens (TV, computers, mobile devices) harmful and should we be limiting our children’s time in front of them?  Normally when we look at holistic health we include all manner of things - from diet and lifestyle to family history and individual health history.   I always ask children (or their parents) about not only their food diet but also their media diet. Just like food, media experiences must be ‘digested’ and fully understood and essentially ‘made our own’.  In the same way rich food can disagree with sensitive stomachs, screen experiences that are too rich or too abundant can overstimulate and disagree with sensitive brains and emotions.  Children do not have the capacity to process in a rational or logical manner screen experiences the way that adults can.  Their developing brains and emotional immaturity put them in a vulnerable position, where too much too soon can leave a lasting impression.

sad childThere has been a big interest in the past few years into how the brain is affected by the increasing screen time that many children are now experiencing. In fact, some argue much of the fear, anxiety and depression that is becoming so prevalent in today’s children is merely reflecting overstimulation and premature exposure to media influences. Some children in my clinic who suffer nightmares, phobias and anxiety often report being scared when watching a movie or a computer game.  Many other children do not understand where their fears and anxieties come from. They are possibly a build up of many different experiences that are poorly digested and appear as behavioural issues, emotional lability or sleep disorders. Parents always report bad behaviour or restlessness after screen time – yet often feel powerless to limit their children’s time.

We all know about the modern ‘explosion’ in children with Attention Deficit/ Hyperactivity Disorders (ADD/ADHD) and autism. Much research is being done and possible causes have been identified – most being related to environmental issues.  These include diverse things from food additives to vaccinations and media exposure. Other researchers are examining the way the brain is changing in children after being exposed to screens.  The instant gratification offered by computers and continuous snippets of information bombarding our brains from surfing the web to SMS messages and emails is literally changing the way the brain is connected and operates.

mediaThe virtual world is very different from the real world. Screens do not readily explore metaphor, abstract concepts or logical narrative. They do not encourage long attention spans or imagination.  Is it any wonder that so many of our kids can’t concentrate or sit still for very long – their brains are programmed from a young age to do the opposite. Screen experiences are always processed in the moment, with very little capacity for follow-up or consequences.  For example when a game allows you to shoot someone, you don’t have to deal with the consequences of that death.  Then if you happen to ‘die’, well you just start over. Susan Greenwood is a leading UK researcher in neuroscience and has observed a real shift in brain function.

"In the current generation if they've been exposed, as most western people have, to screen culture, they will have a shorter attention span and an emphasis of process over content. This means that these young people don't necessarily spend time evaluating the meaning of things and are perhaps rather impulsive and live in the moment, demanding a high degree of sensory stimulation, as opposed to the ability to reflect and think about abstract things."

girl natureIf you need some inspiration to create a new low screen time environment at home, you should check out Susan Maushart’s book, “The Winter of our Disconnect”. It provides a fascinating look behind the scenes at a single mother and her three teenager’s experience of going screen free. Like most teenagers, they were heavy users of online social networking, mobile phones, TV, digital music and computer games.  The book documents many of the issues and withdrawal symptoms that she and her kids had with letting go of their myriad devices.  But the interesting part is how they adapted and how they came to appreciate other things in life.  Her son took up saxophone and her daughters started cooking – and they spent lots of time together as a family.  Without screens to escape to, mealtimes were lingered over and became a time to connect as a family and dusty old board games were given a new lease of life.

A truly holistic view of a child’s health must incorporate their diet, their home life dynamic, screen time and their school and social life.  All these things will impact on a child’s physical and emotional health.  In my view, limiting screen exposure is a responsibility few parents are willing to embrace. Yet, a childhood rich in real life experiences with people, places and the natural world is a gift that will pay dividends.  So consider having a family media holiday – even one day a week - and enjoy the many rewards of connecting with each other rather than a screen.

natural treatment of acne

Natural Treatment of Acne

pimplNearly everyone would have experienced acne at some point in their lives – with more than 85% of Australians experiencing some form of acne between the ages of 13-25 years. The typical spots, known as pimples and black heads, can be mild and infrequent or severe and prolonged, bringing both physical and emotional pain and discomfort. Acne vulgaris is the most common form of acne, but there are other types such as acne rosacea which is more common in adult women.

The teenage years are, of course, when we are most prone to this skin affliction and nothing brings dread into the heart of the average teenager more than a bad case of acne. Puberty heralds an activation of reproductive hormones and this increases the likelihood of acne.

Causes of Acne

Acne is caused by androgens (such as testosterone) stimulating the sebaceous glands in the skin of the face, neck and upper body. This stimulation causes an increase in the size of the glands and also an overproduction of sebum. Too much sebum can cause a blockage which results in the small fluid filled spots known as pimples. Bacteria and white blood cells get trapped in the pimples and multiply quickly causing swelling, redness and discomfort. Blackheads are also caused by too much sebum but the dark appearance is due to the presence of the pigment melanin.

Acne can have a big impact on self esteem

Stress is also a common trigger for acne and while this has always been common knowledge to acne sufferers, only recently have studies been done to prove the impact of stress on acne. Exam stress was found in one study to definitely exacerbate acne in students. Stress is thought to worsen acne due to increased hormones produced by the adrenal glands and also by slowing down healing. Self esteem issues are common in most teenagers, but particularly those with acne. Studies have shown that teenagers with acne experience low self esteem, social isolation and are more prone to depression and anxiety. So it is essential that treatment for acne is holistic and takes into account the psychological elements as well as the physical.

The good news is that there is a lot that can be done to treat acne. Firstly, let's look at the conventional medical treatments and some of the problems with them. Standard medical treatment normally involves long term antibiotics which are aimed at decreasing the infection in the skin. The problem with antibiotics is the destruction of healthy bacteria in other areas of the body, such as the gut. This seems counterintuitive when a healthy gut and bowel function are essential in clearing body wastes including excess hormones as well as supporting optimal immune function. Retinoids (such as roaccutane) are another medical treatment derived from synthetic vitamin A which are used in bad cases of acne. These are powerful drugs with many serious side effects and I believe they are best avoided. There are also topical types of retinoid creams that are less harmful that the oral dose. Other treatments such as the contraceptive pill can be used in women to help balance the hormones that cause acne - however from a holistic perspective this is not really treating the underlying cause.  Natural approaches always aim to determine and treat what is contributing to the complaint.

Natural Treatment of Acne

A diet low in sugar and rich in veggies is essential in treating acne.

A diet low in sugar and rich in veggies is essential in treating acne.

Natural approaches to acne tend to focus on hormone balance, a nutrient dense & low sugar diet, healthy bowel function and stress management. Nutrients that are essential for healthy skin include vitamin A, E and C and the mineral zinc. When these nutrients are deficient, the skin is more likely to be unhealthy and will also scar more readily. Scarring in cystic acne always improves when the right nutrients are supplied.

A healthy diet is absolutely essential in treating acne, but not always easy for the average teenager to adhere to. Sugar is a major culprit in acne as it causes a surge in insulin which in turn stimulates an increased production of androgens which go on to trigger acne flare-ups. So avoidance of sugar and refined carbohydrates such as white flour products like breads, cereals and biscuits will indirectly decrease acne. A good intake of fibre from vegetables, nuts & seeds will ensure excess hormones are removed through the bowel, decreasing the stimulus on acne. Probiotic supplements and fermented foods such as yoghurt, sauerkraut, kimchi or kefir can also be useful as they help to promote good gut health, detoxification and robust immunity.

Burdock is a herb that helps to purify the skin from the inside out

Burdock is a herb that helps to purify the skin from the inside out

Herbal medicine provides many options for acne with hormone balancing herbs, liver and bowel herbs, immune and general ‘skin cleansing’ herbs. Once again, when you have a whole health assessment, we can detect what the underlying trigger for the acne is and then an individual herbal formula can be designed for each case and often gives great results.

Stress management is essential in acne treatments and should include yoga, meditation, massage, exercise and a balance should be sort between work, study and rest. If stress is a big trigger, herbs and flower essences can also help.

Natural Topical Treatments

It is normally best to not squeeze pimples and avoid touching your skin too much as your hands carry bacteria, which can make pimples worse. While, most of the problems with acne come from the inside out as detailed above, there are also some good natural remedies that you can apply to blemishes and pimples to promote healing and reduce inflammation on the surface. Apple cider

vinegar diluted 50:50 with water makes an effective treatment for spots as does lavender oil, teatree oil or raw honey applied to individual pimples. Be sure to find a good natural cleanser, use a microfibre cloth, carry out gentle exfoliation regularly and using a light lotion based moisturiser is normally necessary. Stripping too much oil from the skin can create rebound overproduction of sebum which may aggravate skin further.  Rosehip or argan oil are very good for promoting healing after a lesion has healed and can reduce scarring.

 

Patience is also necessary as all treatments for acne, whether they be natural or drug based, can take at least six weeks to have any noticeable impact, as the skin takes some time to respond.

 

Dangers of Doctor Google

Dangers of Doctor Google

Google-DrWith the advent of google and everyone being able to access health information, the general public has never been more aware and informed about health and disease. This is, for the most part, a wonderful thing. I am a major proponent of patient education and information and most of what I do is to promote self reliance in your diet and lifestyle choices and help you achieve optimal health and prevent disease.

The internet can be a wonderful tool for accessing information, recipes, ideas and other health tips. However, all this comes with a warning. 'Google' and other search engines are not always your friend and may indeed be a foe when it comes to health. There are dangers in seeking online advice, particularly when it comes to diagnosing an illness. Without the medical training and knowledge of tired 2the body, it can be hard to interpret the information and make sense of the often conflicting information. Research in the UK, found that around 25% of women made a wrong diagnosis based on using the internet for their health issues. In many cases they misdiagnosed breast cancer, thrush, high blood pressure and asthma. Researchers also found that at least 10% of women experienced unpleasant feelings and worry after their self-diagnosis.

I have had many instances of patients who have come in after googling their symptoms, and they are full of anxiety that they have a serious illness. Anxiety and panic attacks themselves are often the source of much googling and of course can mimic a range of other serious illnesses. We can get into overwhelm and worry very easily when researching health issues for ourselves or loved ones online. In the worse case scenario, we may make changes to our diet or take inappropriate supplements that can jeopardise our health. High profile cases that have been reported, include Melbourne parents who fed their new born infant rice milk as they were worried about dairy allergy. The infant ended up getting severe malnutrition and died from a systemic candida infection.

Karen@clinicAnother, often overlooked pitfall of managing your own health via online or virtual support is that you get exhausted managing your own health and you may be too close to your own case or your child's cases to get perspective. There is something really liberating in receiving support and care from a trusted practitioner who can give your a clear picture of what is going on and prescribe appropriate measures to take. Letting go and receiving support is healing in itself and is why I still seek the support and care of other holistic practitioners for managing aspects of my own healthcare.

Do You Know Where Your Nutritional and Herbal Supplements come from?

UnknownThe ability to easily access health information online has lead to a massive increase in self-prescribed medicines and people can now buy all sorts of things online from local and overseas companies. Sourcing your own vitamins and herbal supplements may be safe and appropriate. However, it is important to know that there are no safeguards in place for either what you have decided to take or the quality of what you end up purchasing. The quality of online and over the counter supplements can be highly variable.

Manufacturing standards are not as stringent in many countries producing herbal and nutritional supplements as they are in Australia. This includes the USA, China and India who are some of the leading manufacturers of herbal products. Products produced in some of these countries may have elevated levels of heavy metals, pesticides, or microbial contaminants, as herbs are not screened for contaminants in many countries. They may also contain low levels of stated herbal active ingredients, the wrong herb entirely, or be adulterated with other unknown ingredients. Many reported cases of serious side effects from herbal or nutritional products have been traced back to heavy metal contamination or poisonous herbs that were disguised or misidentified and included in the product. Clearly, taking products that are contaminated or adulterated poses a serious risk to the general public, especially those who are already unwell and more vulnerable.

As a practitioner I only source from companies that I can rely on for quality and effectiveness. I need to know that what I am giving my patients is what it says it is to ensure the best effect and outcome. I also need to be confident that there are no hidden nasties in any product such as fillers, binders or preserving agents that might cause allergies or have other negative impacts. For most Australian practitioner quality products, there is a high level of testing and quality assurance.

medherbHere are some of the standard guidelines used by a range of Australian practitioner suppliers who I recommend and prescribe:

  • Herbal ingredients are sourced where possible from organic, fair trade, sustainable or wild-crafted (harvested) crops.
  • Herbal ingredients are tested to ensure the correct material is used and the active ingredients of the herb are at an appropriate level.
  • Nutritional products are formulated with nutrient combinations that are appropriate and synergistic for the desired effect.
  • Nutritional ingredients are tested to ensure correct composition and include the ones that are most active and bio-available for the body to utilise.
  • Products are manufactured under stringent Good Manufacturing Practice conditions.
  • Finished products are tested again to confirm that active ingredients have survived the manufacturing process.
  • Microbiological tests are performed to ensure safety before released for sale.
  • Products are placed on stability trials so that you know what is on the label is in the product and that the product will be active until the use by date.

Thyme

creeping thyme.JPGTime for Thyme!

Thyme is one of my favourite herbs in the dispensary for complaints such as colds, coughs and bronchitis.

The medicinal benefits of thyme have been recognized for thousands of years in many different regions and countries throughout the world. Thyme has a range of medicinal actions including anti-microbial, anti-inflammatory and anti-spasmodic. In addition to thyme chest congestion remedies and using it for respiratory issues such as sore throats, thyme has also been used for arthritis and urinary tract complaints.

Thyme is rich in aromatic essential oils, which is another reason that aside from its use in my clinic, it is also a popular herb in my kitchen for cooking! It pairs well with roast vegetables and meats and the effects of its essential oils on the gut mean that it can also improve digestion. The powerful essential oil has even been shown to be a potent inhibitor of harmful bacterias such as Staph and the tincture of thyme has been found to be beneficial for acne.

balmThyme is an ingredient in my popular lung and cough tea. Another great way to use Thyme is by making a chest rub, that can be a wonderful addition to your winter medicine kit! It is much like the classic Vicks vaporub but uses natural oils and beeswax rather than petroleum jelly as a base (which like other mineral oils and paraffin can leach minerals out of your body). It is super easy to make and lovely to use.

Upcoming Events

There are no upcoming events.

To me Karen is an absolute angel! I highly recommend Karen to anyone who is going through the whole ‘roller coaster’ journey of IVF. It was so lovely to actually have someone that actually listened to me, it was in 2010 when we decided we would give IVF one last go before having a break. Karen put me on a super tonic which I call her ‘magic potion’ and after a few weeks in taking this my FSH levels dropped dramatically and this was my lucky month and my dream had finally came true. I always feel so positive every time I leave Karen’s rooms, I’m so glad that I found her I can never thank her enough for my positive out come!
