Grains are an essential part of the diet, and the Australian Dietary Guidelines recommend for adults to consume 4-6 serves of grains daily. Not all grains can be consumed in large amounts on the low FODMAP diet as some of them are high FODMAP foods. However, it is important to still meet your recommended serves of grains from low FODMAP options.

Fructans: the FODMAP found in common grains

Grains and products made from wheat, barley and rye are all high in the FODMAP fructans. People with IBS may find that fructans are a trigger for their symptoms. Everyone experiences fructans malabsorption, which is normal as they are not absorbed during digestion and pass through to the large intestine. Typically, the body can only absorb 5-15% of fructans. This is due to our bodies not producing enough of the enzyme required to break down fructans in the small intestine, resulting in fructans travelling to the colon and being fermented.

However, fructan malabsorption does not always result in uncomfortable IBS symptoms. When digestive symptoms are present after eating fructans, it is very likely a fructan intolerance. In people with IBS, fructans intolerance can trigger symptoms of bloating and diarrhoea. This is because the fructans molecule is osmotic, meaning that it brings more water into the colon triggering these symptoms. If your dietitian has identified fructans as a trigger for your IBS symptoms, it is important to limit the amount of fructans in your diet.

Why are grains important?

Grains are one of the core food groups and are an essential part of our diet. There are two different types of grains- wholegrains and refined grains.

Wholegrains contain all three layers of the grain:

  • Bran: outer layer of the grain which is high in fibre, B vitamins, iron, magnesium, zinc, copper and phytochemicals
  • Endosperm: middle layer that contains carbohydrates, proteins and small portion of minerals and B vitamins
  • Germ: core of the that includes Vitamin E, unsaturated fats (healthy fats), B vitamins and phytochemicals

In comparison, refined grains such as white grains only contain the endosperm layer, as the bran and germ are removed in the refining process. Whole grains are a better grain choice as they contain fibre, carbohydrates for energy, vitamins and minerals. Even on the low FODMAP diet, there are still a range of wholegrain options that you can choose.

Common High FODMAP Grains

There are a range of high FODMAP grains including wheat, barley and rye, which are high in fructans and other FODMAPs. It is important to limit these in the diet as they can trigger your IBS symptoms.  A typical serve of these foods (2 slices bread, 1 cup pasta/rice, 100g flour) is considered high FODMAP:

  • Gluten free bread (note: varies between brands)
  • Multigrain bread
  • Wheat pasta
  • Spelt pasta
  • Pumpernickel bread
  • Roti bread
  • Rye bread
  • White bread
  • Wholegrain bread

  • Barley flour
  • Whole-wheat flour
  • Chickpea pasta cooked
  • Spelt pasta
  • Semolina

High FODMAP Foods that are Low FODMAP in Small Quantities

Several high FODMAP foods are below the threshold of FODMAPs when consumed in a smaller amount such as 1 slice bread or 50g pasta. However, make sure to test your tolerance level to these foods before regularly including them in your diet.

  • Almond meal
  • Amaranth
  • Oat sourdough bread
  • White bread
  • Wholemeal bread
  • Rice and corn cous cous
  • Filo pastry
  • Chickpea pasta cooked
