Irritable Bowel Syndrome (IBS) Diet Plan
Irritable Bowel Syndrome (IBS) is a diagnosis labelled to any disorder of the intestine, where there is no other apparent pathology. Unfortunately many other diseases often go undiagnosed due to mislabelling as IBS. That's not to say there isn't a genuine condition of IBS; there most definitely is, and it seems to be becoming increasingly prevalent in the West.
IBS symptoms vary from constipation to diarrhoea to intermitted constipation and diarrhoea, and other symptoms may or may not be present: stomach pain/discomfort, urgency, abdominal cramps, blood in stools, flatulence, excessively smelly stools, anaemia, bloating, excessive belching and more. Due to the different symptoms there can be a number of dietary and medical approaches to the treatment of IBS, with varied success. Some people may identify certain food intolerances and need to exclude the offending items from their diet, others may adopt a diet high in dietary fibre, for example see our Meal Plan for Diverticular Disease. Others may trial a low fibre or low residue diet (plan coming soon) to try to control symptoms. Some people however try a number of dietary regimens, with zero success, and so may need medical intervention and further exploration.
However, the first dietary manipulation suggested is the low irritant diet. The principles of this diet are to avoid irritant foods and also to reduce high intakes of fatty foods. Fibre needs to be included in your diet, but certain high fibre foods may irritate the bowel. This regimen encourages a good fibre intake, whilst avoiding certain irritant fibre foods. High fat foods may also exacerbate symptoms so should be limited. It is also important to drink well – 12 cups of fluid per day. Avoid strong tea and coffee, and limit fizzy drinks and alcohol. It is also important to eat a wide variety of foods and to eat regular meals, don't miss meals. Adapt the plan to suit your own needs and daily routine and vary portions and food choices from day to day.
