IBS attacks can get triggered by:
Greasy Food
If your digestive system is sensitive, you should avoid fried food and fatty meats. Food with high-fat content can increase contractions in the intestine for the bowel movement more than what is required.
This doesn't mean avoiding fat altogether. Food with healthy fat, such as nuts and fish, can be beneficial for digestion and overall health.
Dairy Products
Many people suffer from a condition called lactose intolerance due to which their bodies find it difficult to digest the sugar found in dairy products. Lactose intolerance can lead to digestive symptoms like cramping, bloating and diarrhea.
Gluten
Although a high fiber diet is important for digestion, certain high fiber foods can be problematic. For people with celiac disease, intake of a protein called gluten can cause the body's immune system to attack the small intestine and result in serious health problems. Gluten is found in some whole grains like wheat, rye and barley.
Soda
Soda is carbonated water and it can contribute to problems like intestinal gas and bloating. The high amount of sugar in regular soda may add to an imbalance in your gut bacteria and cause further gas.
