If you don't eat gluten or wheat then you are part of a very large club.  It seems that more and more people seem to be going grain and gluten free, and for a variety of reasons. For some people it is critical to their health for no gluten not to pass their lips, while others may be avoiding wheat unnecessarily, without really knowing if their body is better off or not.

The original wheat avoiders are those with coeliac disease who simply cannot tolerate a crumb of any gluten-containing food.  Gluten is a protein found in wheat and related grains such as rye, barely, triticale and oats.  Gluten truly is toxic to people with coeliac disease as it damages the lining of the small intestine and must be avoided at all costs for short-term digestive comfort and long-term health. 

Wheat can also cause digestive symptoms if you don't have coeliac disease.  If you are following a new eating style then you also may be avoiding wheat, and this may or may not be necessary.  I was speaking with the owner of a cake business recently and he mentioned the increasing sales of his flourless cake range.  Upon asking his customers why they are choosing the flourless, the frequent answer is 'because it is healthier'.  But is it really healthier for everybody?  Many people do need to avoid wheat products but how do YOU know if you should avoid wheat and gluten?  Here are the three main conditions that lead to avoidance of gluten and wheat:

- Coeliac disease

  Nil gluten allowed, full stop.

- Fructose malabsorption

More and more people are being diagnosed with fructose malabsorption.  The hydrogen breath test companies must be raking it in, with fructose and lactose malaborption testing readily available and although lengthy, can provide an indication of existing intolerances.  If your gut does not absorb fructose well, it is likely you may have trouble with fructans, which are found in wheat-based foods (individual tolerance varies significantly, so it is worth seeing an Accredited Practising Dietitian for more advice so that you are not avoiding foods that you could be enjoying).

- Gluten sensitivity/intolerance or Irritable Bowel Syndrome

Many people describe a range of gastrointestinal symptoms that improve when they stop eating gluten, so the natural inclination is to think this is a 'gluten sensitivity’.  There are a wide range of factors that can cause gut symptoms, including stress which is sometimes overlooked.  

Research has shown that gluten may not be the main culprit when it comes to Irritable Bowel type symptoms, but it could be the malabsorption of fermentable sugars (FODMAPs), some of which are present in wheat-based foods.  It is worth investigating a little further if you have gastrointestinal symptoms, see your doctor and specialist/s if required to ensure you are making dietary choices that are appropriate for your individual circumstances. 


The other popular reason that people avoid wheat is because the latest diet they are following tells them to!  Whether it be Paleo, LCHF, Atkins.....many fad diets recommend a reduction in carbohydrate, which is often very successful for weight loss, but unfortunately some diets also imply that 'wheat is toxic'.  Yes, toxic to someone with coeliac disease, but not for most people.  Personally, I am all for reducing carbohydrate as I think most people eat too much, but if you have a healthy digestive system then you should have absolutely no trouble digesting wheat. 

Some people DO just feel better avoiding wheat.  If you cut out wheat you are not just avoiding nutritious carbohydrate foods like wholegrains - you will also omit cakes, biscuits, savoury snacks, pastries and many other processed, high sugar and low-nutrient foods.  So it makes sense you would feel better and probably lose weight eating less of the latter.

Poor old bread seems to get terribly bullied when it comes to grain bashing, it is always the first food to be discarded when there is a change to wheat-free.  But it may not be the rye/spelt/wholegrain slice that is contributing to digestive symptoms.  It may just be the amount....think big thick sandwiches (the ones you buy at sandwich shops are often equivalent to about 4 pieces of standard bread) and overflowing bowls of a bit less at each sitting, and slowly, and your digestive symptoms could likely improve.

Be aware that sometimes a change to wheat and gluten-free can lead to weight gain rather than weight loss, not to mention constipation if fibre intake is reduced.  Some of the gluten-free substitutes are low in fibre and can be higher in fat/kilojoules, and often not as filling as wholegrain wheat options.  This is important to consider if you are eating gluten-free and trying to lose weight. 

If you DO need to avoid wheat, and you train really hard, it can be a real challenge to make sure you are eating carbohdyrate foods that are nutrient-dense (rather than living on processed gluten-free bread, rice crackers and jelly lollies for carbohydrates).  Here are some super nutritious wheat and gluten-free foods that will give you carbs to power your training and have you recovering like a champ, without the gastrointestinal issues.  

POTATO (SWEET OR WHITE) - For some reason potatoes have gone out of favour in recent years, but as far as a natural source of carbohydrate, you can't go past nutritious potatoes.  Often sweet potato is recommended over white, usually because of its lower glycemic index and vitamin content, but white potato with a higher glycemic index is terrific for post-exercise meals, and is fine when combined with other vegetables anyway.  Remember, although potato is higher carbohydrate than other vegetables, it is still a lot lower in carbohydrate than rice, pasta, and many other grains ( for example, the carbohydrate content of white potato is ~12.5g/100g cooked, sweet potato ~19g/100g cooked, brown rice ~30g/100g cooked).

SWEET CORN - Sweetcorn is another sneaky source of carbohydrate, also packed with nutrients and fibre, and a similar carbohydrate content to white potato at ~13g/100g cooked.  Great in salads, soups, main meals or a cob of corn as a snack.

QUINOA - Probably the most over-promoted and over-estimated food in the world, if you can afford quinoa it is still a great gluten-free 'seed' (see my comparison of oats an quinoa for more detail Oats vs quinoa for health, energy and performance.

RICE - Super-rich in carbohydrate, try the different colours and varieties of rice, or one of the many rice mixes available these days (such as rice with lentils or quinoa) to boost the fibre and nutrient content.  There is nothing wrong with white rice too, especially if you get lots of fibre and nutrition from other foods.  If you are looking for optimal nutrition value though,  go for the less processed varieties (but not everything you eat has to be wholegrain or brown all the time!).  If you are active, sometimes too much fibre can be a problem with stomach symptoms, particularly around competition.

OATS* - Oats are still controversial for people with coeliac disease and in Australia oats are not permitted to be considered gluten-free, although in many European countries uncontaminated oats are considered safe.  The issue is complex and relates to contamination risks during processing and also a component in oats called avenins that some people can react to.  For those avoiding wheat for reasons other than coeliac disease, enjoy oats regularly.  For more info on oats see my previous blog mentioned above Oats vs quinoa for health, energy and performance.

RYE/SPELT BREAD (not suitable for coeliac) - If you have coeliac disease you need to avoid rye flour and all bread needs to be of the gluten-free variety.  But if you are trying to reduce gluten for other reasons then choosing a bread with a high proportion of rye vs wheat, or a spelt slice, can be a tasty source of carbohydrates.

GLUTEN-FREE PASTA - Pasta is a quick and easy carbohydrate option for active people. Gluten-free pasta has improved over the years, and you can now find a wide range of varieties in most supermarkets.  If it's a while since you have tried gluten-free pasta, give some a try, combine with lean protein and vegetables or salad for a balanced meal.

MILLET - I have a confession to make.  Only once have I knowingly eaten millet.  Well, millet flour, when I was trialling some gluten-free muffin recipes.  This sounds very hypocritical, to incude millet on this list but not really eat it myself!  I am one of the many fortunate people who does not have a problem digesting wheat and wheat products, although to be honest I don't actually eat a lot of wheat on a day-to-day basis.  I am not on the lookout for wheat subtitutes for personal use, but I acknowledge the nutrient value of millet (it is a wholegrain, contains fibre and rich in magnesium). Try millet as a side dish with savoury dishes in the place of rice, or mixed together with quinoa or rice or made into porridge for breakfast.

AMARANTH - Again, not a regular staple in my cupboard, but amaranth is a nutritious pseudo-cereal (not officially a grain, but is used in similar ways and has a similar nutrition profile to other grains).  Amaranth contains a range of minerals (such as calcium and iron), and has one of the best amino acid profiles of plant-based proteins.  In Australia amaranth is commonly seen in dry cereals, but can also be cooked and used in dishes such as porridge and soup.  In many countries it is popped and eaten like popcorn.

POPCORN - Speaking of won't quite do the job for recovery needs, due to its carbohydrate content being so low, you would need to eat buckets worth.  But its low carbohydrate and energy density (1 small packet of popcorn only weighs 13g, with only 6g carbohydrate and ~55 calories) makes this a terrific wholegrain snack for active people who may be trying lose weight.  A great alternative to potato crisps or other savoury snacks, which are often a popular choice when eating gluten-free.  Make sure you go for the plain varieties, not the sugar/caramel coated options.

These are just a few nutritious and convenient options to help fuel your training and recovery.  For more ideas, see Better Health Channel - Gluten-free Diet for an easy to read listing of gluten-containing and gluten-free foods.
