Low FODMAP diet is more effective than sticking to a low fat diet for symptoms of IBS (irritable bowel syndrome)

Irritable bowel syndrome affects 10% of the population and is very common. Symptoms include abdominal pain, distension, altered stool consistency (hard or soft) and altered stool frequency ( diarrhoea or constipation). First line treatments include – regular exercise, low fat diet and soluble fibre starting at a low dose (British Society of Gastroenterology recommendations).

Hot off the press (GUT journal doi:10,1136, 2022) scientific research reports that a diet low in FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) is more effective than the first line recommendations for improving IBS symptoms. A low FODMAP diet is not forever and should be tried for limited periods preferably with the supervision of a trained dietician.

A good place to start would be to avoid high FODMAP foods in your diet:

  • apples
  • wheat
  • margerine, cream, custard
  • baked beans
  • lentils
  • honey
  • onions
  • garlic.

Now try to incorporate low FODMAP foods instead;

  • avocado
  • kiwi (great for constipation!)
  • maple syrup
  • butter
  • parmesan, brie, mozzarella
  • broccoli, carrots, green beans, aubergine
  • brown rice
  • brazil nuts
  • eggs, fish, chicken.

I would recommend keeping a food diary, daily , alongside abdominal symptoms and stool chart.
