IBS - Nutritional Management
Diet and nutrition should be assessed for people with IBS and the following general advice given.
Have regular meals and take time to eat.
Avoid missing meals or leaving long gaps between eating.
Drink at least 8 cups of fluid per day, especially water or other non‑caffeinated drinks, for example herbal teas.
Restrict tea and coffee to 3 cups per day.
Reduce intake of alcohol and fizzy drinks.
It may be helpful to limit intake of high‑fibre food (such as wholemeal or high‑fibre flour and breads, cereals high in bran, and whole grains such as brown rice).
Reduce intake of 'resistant starch' (starch that resists digestion in the small intestine and reaches the colon intact), which is often found in processed or re‑cooked foods.
Limit fresh fruit to 3 portions per day (a portion should be approximately 80 g).
People with diarrhoea should avoid sorbitol, an artificial sweetener found in sugar‑free sweets (including chewing gum) and drinks, and in some diabetic and slimming products.
People with wind and bloating may find it helpful to eat oats (such as oat‑based breakfast cereal or porridge) and linseeds (up to 1 tablespoon per day). [Reference]
