Essential whole grains and pseudo cereals

Grains are the edible portion of cereal grasses that belong to the Gaminae family. The term whole grain refers to a grain or grain-based product that contains all three of its main parts – the endosperm, bran and germ.

Whether you have coeliac disease or non-coeliac disease gluten intolerance, your health will depend on the strict adherence to a GF diet – and removal of all wheat, rye and barley. Fortunately, despite having to avoid a number of gluten-containing whole grains, there are still a good variety of gluten free whole grains available, such as brown rice, corn, millet, sorghum, teff and wild rice – as well as the pseudo-grains of amaranth, buckwheat and quinoa. Pseudo grains are those grains that are not grasses but are similar in content and can be used in a similar way to grains.

What are whole grains?

Whole grains not only ass nutritional value to products, but also add texture, flavour, visual appeal and variety to the diet.  Eaten in combination with other whole foods, they are also generally more filling and satisfy for longer than refined grains.

Gluten free grains have become more readily available over the last few years. They have also started to appear in gluten free manufactured products, such as breads and breakfast cereals, but these still tend to be in small amounts.

Nutritional value of whole grains

A whole grain is made up of three parts – the bran, germ and endosperm. The bran is the outer protective layer of the grain. This contains fibre and a large percentage of the B vitamins found in a whole grain. The germ contains unsaturated fat, vitamin E, some protein, minerals and B vitamins.

The endosperm is made up mostly of carbohydrate and protein, with some B vitamins. Since the bran and most of the germ are removed during the refining and milling of grains, the majority of fibre, minerals and vitamins are lost. Other beneficial phytonutrients such as lignans, phytoestrogens and phenolic compounds are removed as well.

In regard to gluten free whole grains, amaranth is high in calcium, iron, magnesium and fibre. Buckwheat is a good source of fibre and some B vitamins. Millet is high in B vitamins and fibre. Teff is high in calcium, iron, magnesium, zinc, B vitamins and fibre. It is also the only cereal to contain a high lysine content, which makes its protein content similar to that of cow’s milk. Wild rice is high in zinc, magnesium and folate. Brown rice and sorghum are a good source of fibre.

The advice for newly diagnosed coeliacs is that oats, even if uncontaminated from other gluten containing cereals, should be routinely avoided.  However, studies also show that a majority of individuals with Coeliac Disease and those with non-Coeliac gluten intolerance can tolerate some (uncontaminated) oats.  As a good source of wholegrain, oats are readily available and affordable, but uncontaminated ones are not – these are often expensive as they are imported into NZ.  Individuals with Coeliac Disease should, however, not add oats to their diet without medical supervision.

Other Characteristics

Whole grains not only add nutritional value to products, but also texture, flavour, visual appeal and variety. They are also generally more filling and satisfy for longer compared to refined grains.

Availability and Cost

Gluten free whole grains have become more readily available over the past few years. They have also started to appear in gluten free products such as bread and breakfast cereals but usually in small amounts. Gluten free whole grains are often available from good supermarkets, health food shops, organic food stores, Bin Inn, specialist gluten free food stores, and Indian and Asian food markets.

Cross Contamination

If you have coeliac disease or you are sensitive to small amounts of gluten then it is important to avoid even traces of gluten. A real issue to consider when purchasing gluten-free whole grains is whether they have been contaminated. Just because a grain is naturally gluten free does not mean it will be gluten free when it reaches the shelf! It could have been contaminated with gluten in the fields or during storage, processing, packaging or transportation. It is safest to purchase pre-packaged whole grains that state they are gluten free.

How many whole grains to eat?

I don’t know of any country, including New Zealand, that has set guidelines on the quantity of whole grains that should be included as part of a gluten free diet. However, for the general adult New Zealand population, the Ministry of Health recommends that plenty of breads and cereals (6+ servings per day, depending on weight, age and activity levels), particularly whole grain varieties, are eaten. This is probably a suitable recommendation for those on a gluten free diet.

Ways to add whole grains to your diet

Breakfast

  • make a hearty porridge with ground amaranth, quinoa, buckwheat, sorghum, or millet.
  • make a GF muesli, adding in buckwheat groats, puffed brown rice, quinoa, amaranth, and millet.
  • choose bread that contains a high proportion of gluten free whole grain. If making your own bread, aim for at least half of the dry ingredients to be whole grains.
  • have gluten free Weetabix. These can be eaten as is or crumbled over another cereal or muesli
  • include buckwheat pancakes occasionally

Lunch

  • enrich soups with brown rice, buckwheat, millet, quinoa, sorghum, or wild rice.
  • make salads based on whole grains such as brown/wild rice or quinoa/buckwheat (tabbouleh)
  • if having bread/toast based lunches, choose a GF bread high in whole grains
  • make sushi with brown rice or quinoa

Dinner

  • add cooked buckwheat, quinoa, or wild rice to pilaf or rice risotto
  • choose a gluten free pasta made with whole grain-based flours such as brown rice, amaranth, quinoa, or millet
  • extend meat loaves or mince patties with cooked buckwheat, quinoa, amaranth or teff
  • thicken casseroles with amaranth, millet or teff
  • serve stir-fry or curries with brown rice or quinoa
  • use quinoa or buckwheat flakes to make fruit crumbles

Snacks

  • enjoy popcorn as a snack
  • choose whole grain rice or corn crackers
  • enjoy yoghurt with a sprinkle of GF whole grain-based muesli
  • occasionally have GF baking in which at least half the dry ingredients are whole grain flours
  • occasionally enjoy gluten free wholegrain corn chips
