Be Well Gluten Free – Mythbusting by Sally Marchini

So many of us are encouraged via various influencers to try going ‘gluten-free’.  As an Accredited Practising Dietitian who has a special interest in this area it’s an issue I deal with and research every day. In this article I would like to cut through all the marketing speak for you and, based on current scientific knowledge, explain a little of what it all means.

Up front we have coeliac disease (CD). CD is an autoimmune medical condition that in Australia effects about 1 in 70 people, and around 80% of those go undiagnosed. The diagnosis of CD can be overwhelming for many but it is critical for long term health that people with CD follow a strict lifelong gluten free diet. This is because it is the protein gluten that causes an inflammatory response in these people, which can lead to various ongoing health issues. Even a small amount of gluten that’s not enough to cause symptoms will cause the inflammatory response – hence the need for it to be a strict diet.

Gluten is a protein that is found in wheat, barley, rye and oats and some derivatives of these grains. Gluten is not the only component of these grains that can cause people to feel unwell. If it’s not the gluten that’s causing you to feel unwell (which you wouldn’t know unless you had CD ruled out) then the outcome is a much nicer story with no long term damage risk. And the associated symptoms are dose dependent, so easy to manage. This means that with the assistance of an Accredited Practising Dietitian you can work out what your tolerance levels are, and know that if you really feel like that piece of wheat based cake regardless of your symptoms, you can have it.

Wheat Allergy is a recognised medical condition and affects an estimated 0.27% of the population. It’s unrelated to gluten/CD and people with it must strictly avoid wheat. There is also a condition known as Non-Coeliac Gluten Sensitivity (NCGS), but the long term health of those with it is not put at risk by accidental gluten intake.

Unless it is medically necessary, going ‘gluten-free’ is not a healthier option.  If it means that you cut out processed foods such as fast foods, pies, cakes and biscuits from your diet then you can see that it may be beneficial in encouraging more fresh food intake, which will make you feel better. But many of the ‘gluten-free’ options for the processed foods contain less fibre, more fat, more salt, fewer nutrients and are more expensive.

Let’s look at some facts to help put it all into perspective:

  • 2014 research by the Grains & Legumes Nutrition Council (GLNC) indicated that 14% of people listing CD as their health condition reported self-diagnosis. This puts them in a high risk category for misdiagnosis which could be potentially dangerous to their health in the longer term.
  • In the same survey by the GLNC, 49% of respondents indicated that their reason for wheat avoidance was that it makes them feel bloated. Bloating is associated with both CD and FODMAP intolerances, so how can one diagnose on this basis?
  • According to Dr Sue Shepherd, if you combine Irritable Bowel Syndrome (IBS) and NCGS stats, about 1 in 5 people (20% of the Australian population) are affected by the ‘gluten’ containing grains.
  • Coles revealed that in 2013 four out of ten of their shoppers were purchasing gluten free foods.
  • 10-15% of the Australian population suffers IBS, of which 75% can be treated by following a low-FODMAP diet.

Can you see the risks of self-diagnosing based on these numbers? Please don’t do it.

Let’s talk about the wonderful low FODMAP diet. Developed by an Australian Accredited Practising Dietitian in response to her clients’ common complaints, Dr Sue Shepherd’s PhD research is used and further studied across the world to help people who suffer bloating, constipation, diarrhoea, pain and other gastrointestinal disturbances. I mentioned further up about working with an Accredited Practising Dietitian to work out what your tolerance levels are – well here’s how it works.

FODMAPs (Fermentable Oligosaccharides Disaccharides Monosaccharides and Polyols) is an acronym which basically means carbohydrate types that are not broken down sufficiently in the digestion process and enter the large bowel where they ferment, attract water by osmosis and feed bacteria that create gasses. This all contributes to the symptoms people experience with IBS.  Dr Shepherd has created a short term diet (6-8 weeks) where all foods containing FODMAPs are removed from the diet. Your dietitian will help you to find suitable alternatives and ensure your diet remains nutritionally balanced. The next stage is called ‘Liberalisation’ and involves reintroduction to determine your tolerance levels within each group.

Within the 5 FODMAP groupings there’s one called ‘Fructans and GOS’ which, among other foods, includes wheat, barley and rye (3 of the 4 gluten containing grains) and these foods are malabsorbed in everybody.  Some people experience worse symptoms in this group than others, so it’s all about finding your tolerance level. If it’s found that you are sensitive in this grouping and haven’t yet had CD ruled out, it’s strongly suggested that you do. Reintroducing the gluten containing grains for the gluten challenge before testing for CD is not a positive experience but there are ways to make it more bearable, which your dietitian can explain.

In summary, it is important to see an Accredited Practising Dietitian before putting yourself on a restrictive diet for the reasons of potential misdiagnosis, malnourishment and unnecessary restriction of otherwise nutritious and delicious foods. The closed Facebook group ‘Be Well Gluten Free’ has about a dozen Accredited Practising Dietitians as members so you can feel safe with the input of qualified health care professionals to ask your questions and find out in a balanced way how you should progress for your own best health interests.
