From the point of view of nutrition, the foods you eat e.g. eating broccoli which may cause bloating or too much or too little fibre, can impact on all types of IBS.
You may have heard that a low FODMAP diet can help IBS – yes, this can be very helpful. FODMAP foods, when processed by your digestion, can produce gas. This gas can cause bloating, and abdominal discomfort.
FODMAP foods resist complete digestion; they pass into the large intestine or colon where the bacteria in your colon ferment these foods; this produces gas which in excess causes the discomfort you experience. FODMAP foods are not bad foods. In fact they are a fuel for the friendly bacteria. But some people are more sensitive to the effect of FODMAPs foods.
To help reduce your symptoms we recommend you find out what FODMAP foods your digestion is reacting to. FODMAP foods are common foods that have health benefits e.g. garlic, avocado and beetroot, but when eaten in specific amounts usually more than your digestion can handle will cause these digestive symptoms. It does not do you any harm to eat these foods, if you do get symptoms there will be no long term damage. But it is recommended that for a period of time you reduce FODMAP rich foods and then you can have a trial period where you re-introduce into your diet to see how your digestion handles them.
It is important to get guidance as many people remove a lot of foods from their diet. We must remember that most plant foods contain carbohydrates and it’s important to not overly restrict your diet. Having a nutritional and dietary assessment and plan will help you to manage your diet and get the symptom control you seek by following a low FODMAP diet.
