Certain foods and beverages can aggravate your signs and symptoms, especially during a flare-up. If you think eating certain foods make your condition worse, keep a food diary to keep track of what you're eating as well as how you feel. If you discover some foods are causing your symptoms to flare, it's a good idea to try eliminating those foods.
Like many people with inflammatory bowel disease, you may find that problems, such as diarrhea, abdominal pain and gas, improve when you limit or eliminate dairy products. You may be lactose intolerant — that is, your body can't digest the milk sugar (lactose) in dairy foods. If so, limiting dairy or using an enzyme product, such as Lactaid, will help break down lactose. However, milk and dairy often fill key nutrient gaps in one's diet so make sure to have an adequate supply of calcium, vitamin D, and protein to replace this intake.
