Is the FODMAPS diet the only option for Irritable Bowel Syndrome [IBS]?

Most people have heard that diet has a role in Irritable Bowel Syndrome [IBS]. Usually it is assumed that the only diet option is to lower all the food that cause bloating and wind and the discomfort, even spasm pain that may follow. This is the FODMAPS diet which is useful for those symptoms. However there is another option, especially for those who have severe pain, crampy pain, looseness, bowel urgency with a wave of almost feeling faint as the motion is passed. For these symptoms the low chemical diet can reduce the symptoms. This diet minimizes suspect additives, salicylates, amines, and monosodium glutamate [MSG]. Everyone has their own variety of symptoms and sometimes their symptoms are a mixture of these two types. It is worth getting the help of an accredited practising dietitian so your diet is not too strict, and testing food for tolerance is really clarified. There is lots of information that helps with understanding  IBS in the [Articles] section of the website. These include Stories of IBS food sensitive patients, and the new one on FODMAPS or food chemical intolerance, how do you decide?  See  https://foodintolerancepro.com/category/irritable-bowel-syndrome/
