nutrition

Nutritionists apply knowledge of the therapeutic & preventive potential of food, diet & supplements including vitamins, minerals & trace elements to maintain and promote our patient's health. The nutritionist may plan appropriate patient-based diets and prescribe nutritional supplements for general well being, or to treat clients with specific health conditions. Studies in nutrition are supported by a strong underpinning of biological and social sciences subjects.

A nutritionist assesses a patient’s diet for nutritional deficiencies and also determines particular nutritional deficiencies by the symptoms a patient has. For example, spasms and twitches of the eye are a symptom of magnesium deficiency. White spots on the nails are either zinc or calcium deficiency etc. My priority is to replace with supplements and maintain with food. In an ideal world, we can get all our nutrients from our food, however, the 21st century poses many challenges, with non-organic farming methods, environmental pollution including the current plastic apocalypse and the overuse or abuse of pharmaceuticals indicate the need for supplementation. Deficiencies in Vit A, Vit D, B complex, iron, calcium, magnesium, iodine, selenium, essential fatty acids and many more are widespread. 

My focus is always on foods that are the known richest sources of a nutrient to prevent a condition. For example, sulforaphane and indoles rich broccoli to prevent prostate cancer, isoflavone-rich Kudzu root powder to prevent hormone dependant female cancers and beta-glucan-rich oats to lower your cholesterol etc. Most importantly I tell you what you can eat, not what you cant. I will prescribe a diet that is suited to your lifestyle and environment and your social life. My philosophy is to take stress off the menu, enjoy your food life!

Nutritional supplementation 
In an ideal world, a balanced and varied diet is the best source of essential vitamins and minerals. In reality, however, nutrient deficiencies can and do occur, including in populations with bountiful food supplies and the means to procure nutrient-rich foods. For example, the Standardised American Diet (SAD) bears little resemblance to what experts recommend for fruit, vegetables, and whole grains, which serve as important sources of an array of vitamins and minerals. With time, deficiencies in one or more micronutrients may lead to serious health issues. So dietary advice and nutritional supplementation prescriptions are absolutely warranted.

Not all nutritionists are created equal
In Australia a naturopathic degree is a degree in herbal medicine and nutrition. Naturopathy is not pseudo science. The problem with the industry, is not the lack of evidence for herbal medicine and supplements, but the lack of regulation in both the education sector and the industry, resulting in the difference in qualifications of your homeopath, acupuncturist, naturopath or nutritionist. In order to successfully integrate Complementary and Alternative Medicine (CAM) into main-stream healthcare the basis of training of CAM practitioners needs to be equivalent to university degree programmes offered currently to mainstream health professionals. Australian naturopaths study an internationally recognised transferable level 8 (EQF/AQF/NFQ/Level 6 Ofqual recognised by NARIC Ireland/UK ) honours science degree. The naturopathy degree I completed, indeed the 3 degrees I completed, were all 4 year full-time Bachelor of Health science degrees with contact hours equalling 24 hours per week or 96 hours per month. Some naturopathy courses are 3 year part-time courses equating to 14 contact hours per month only. These course are not internationally recognised. An naturopath with a science degree as a firm understanding of medical pathology, pharmacology. Being trained in pharmacology and drug nutrient drug/herb interactions, Australian naturopaths work in every pharmacy and health food store to advise pharmacists of drug/nutrient and drug/herb safety to protect Public Health.  

Australia is at the forefront of natural medicine training, having offered degree programmes for 20 years. The industry is well-regulated and moving towards registration with the Australian Health Practitioner Regulation Agency (AHPRA) the national registration body that develops a nationally consistent approach to auditing health practitioners including doctors, nurses, acupuncturists and allied health professionals. I was, while living in Australia, a registered acupuncturist. Common registration standards include criminal history checks, ensure English language skills are met and ensures all it's members meet continuing professional development requirements. Registration standards are regularly reviewed. This national registration body will, soon cover Naturopathy as a discipline. 

Nutritional supplementation and safety
The use of dietary supplements is primarily self-initiated rather than practitioner-based and presents unique regulatory, safety, and efficacy challenges to consumers, researchers, and practitioners. Many supplements are contraindicated with certain medications. Many supplements should not be taken together. Some need to be taken before or after meals. Many people are taking too much or alternately not enough of the supplement. Excess dosing, particularly of fat-soluble nutrients, can be dangerous as they accumulate in the liver. Taking too little equates to taking none at all. Like herbal medicine, supplements need to be taken in their correct therapeutic doses in order for them to work. This can only be achieved by seeing a qualified practitioner. I would never recommend someone self-prescribe supplements. It is strongly advisable if you are taking a supplement or are considering taking supplements that you have a consultation with a degree qualified practitioner who is adequately trained in drug/nutrient interactions to ensure safety and is able to ensure you are taking the right supplement is in the right form and taken at the right times.

Not all nutritional supplements are created equal
On top of the safety issues, not all nutritional supplements are considered equal. Some supplements are bioavailable meaning they can be and able to be digested and absorbed and used by the body. Some are not bioavailable and as much use as a chocolate teapot or even worse can cause disease. For example, the most common and least expensive type of supplemental calcium available is calcium carbonate. This supplement is poorly assimilable therefore unable to be absorbed. Thus making it not only doesn't strengthen your bones, on the contrary, but it is also excreted by the kidneys and can contribute to kidney stones. Calcium carbonate is also an antacid so neutralises stomach acid and inhibits absorption of both calcium and iron so taking calcium in this form can actually lead to osteoporosis and iron deficiency anaemia. Supplements need to be prescribed in their correct form to ensure they are bioavailable. Supplements that are in the wrong form and not bioavailable are as much use as a chocolate teapot. I can prescribe practitioner only nutritional supplements that are readily absorbed and utilised.

Determining food allergy or food intolerance
A nutritionist can determine food allergy or intolerance. In fact, these words often get misused by many under trained practitioners. Food allergy is described as an immunological reaction involving the production of an anti-body whereas food intolerance is described as a pharmacological reaction to the compounds in foods, similar to the side effects when taking medication. The word allergy should be reserved for reactions that involve the immune system only. A true food allergy requires the presence of IgE antibodies against the food.
A common example of misuse is when people say they are allergic to cheese because it gives them headaches. This reaction is not an allergy, but actually food intolerance to the vasoactive amines in the cheese. In reality, food allergy affects relatively few people but can be quite severe when it does.

A good nutritionist will use a low reactive diet and an oral food challenge to test for food allergy. This is the gold standard test. Machines will give false positives due to different circumstances. A nutritionist will prescribe foods known as “living foods” or “super foods”. These are enzyme rich and nutrient dense foods.

Fasting is not junk science
Fasting is a useful therapeutic tool prescribed by naturopaths and nutritionists for certain health conditions. Fasting is Calorie Restriction (CR). The benefits of CR are scientific fact. A therapeutic fast simulates the Calorie Restrictive Diet that scientists have touted for the main reason behind Okinawan longevity. Like CR, fasting also activates telomerase the anti-ageing enzyme. Fasting, like CR, improves how cells respond to stress, how they break down (autophagy), induces apoptosis (programmed cell death ie in cancer cells), and alters hormonal balance. Autophagy in particular, is quality control inside cells. It is essential to maintain cellular homeostasis and to improve how the cell responds to stress. Autophagic activity declines with age, therefore fasting is anti-ageing. In relation to heavy metal accumulation, CR/fasting and ketosis whihc mimics CR/fasting enhances Phase II Detoxification thus will assist in the elimination of heavy metals, plastics including BPA/pthalates, dioxins and furans and other persistent toxic substances (PTS).

My preferred take on fasting
Fasting is a difficult and anti-social experience and difficult to achieve in the modern working day, however, so my approach is to mimic fasting to achieve all the benefits of fasting without the pitfalls. This is why I recommend a ketosis diet in addition to where appropriate, therapeutic fasting. This diet is a carbohydrate restrictive, high good fat, high healthy protein (including veg/vegan based protein) diet. Ketosis is a perfectly normal metabolic process. When we are unable to use carbohydrates as fuel for cells to burn for energy, fats are used instead. Ketones are produced as part of this process. In fact, ketones are the preferred source of fuel for our bodies. This diet can be adjusted and made suitable for vegetarians/vegans.

Benefits of a Keto Diet

Lowers cholesterol: Lowers LDL & triglyceride levels and raises HDL (good cholesterol). (1)

Induce Rapid Weight Loss: Reduces body weight and body mass index. (1)

Lowers Blood Sugar: Studies show a ketosis diet can eliminate type 2 diabetes. (2, 3)

Enhances physical and cognitive performance: Ketone bodies are the most energy-efficient fuel and yield more ATP. (4)

Suppresses Appetite: High fats diets increase satiety. (5)

Starve Cancer Cells: Cancer cells need glucose for fuel. Only healthy cells can live on ketones. Studies indicate a ketosis diet is an adjunct therapeutic aid in cancer. (6, 7)

Treats neurodegenerative disease: Ketosis is neuroprotective and neuroregenerative (8) & therapeutic treatment in traumatic head injury, neurological disease (9) including Parkinson’s, Alzheimer's (10) & epilepsy, (11)

Extends Life: The benefits of Calorie restriction/Keto diet are scientific fact. A Ketosis diet simulates the Calorie Restrictive Diet (12) that scientists have touted for the main reason behind Okinawan longevity. Like CR, Ketosis also activates telomerase the anti-ageing enzyme. Calorie restriction increases telomerase activity and enhances autophagy (breakdown of dead cells). (13) CR improves how cells respond to stress, how they break down (autophagy), induces apoptosis (programmed cell death ie in cancer cells), and alters hormonal balance. Autophagy in particular, is quality control inside cells. It is essential for the maintenance of cellular homeostasis and for the orchestration of an efficient cellular response to stress. Autophagic activity declines with age, and this contributes to the ageing process. (14)

The Keto Diet also aims to;

Stabilises blood sugar to reduce cravings for carbohydrates.
Improves insulin sensitivity to treat Metabolic Syndrome & address central obesity.
Promotes bile flow from the liver to assist fat metabolism & address a “Sluggish Liver”.
Tonifies the thyroid gland to boost the Basal Metabolic Rate (BMR).
Addresses the mental emotional disorders that lead to comfort eating & food addiction.
