The 9 biggest triggers of Irritable Bowel Syndrome

1. Dairy foods

Dairy can be problematic for some people for 2 main reasons. The first reason is that dairy contains fat which can increase the incidence of diarrohea. Switching to non-fat or low-fat dairy may lesson symptoms. The second reason is that many people with IBS are lactose intolerance. Meaning they react to the milk sugar lactose that is contained in dairy as they don't have a significant amount of the enzyme lactase that helps to digest and breakdown lactose. As there can be varying levels of lactose intolerance, you may be able to handle a certain amount of Lactose, so it will be trial and error to see the amount that is tolerable until you see symptoms appearing.
