No known dietary or lifestyle changes prevent inflammatory bowel disease (IBD), and no known dietary substances have been consistently shown to cause activation of IBD. Tobacco use has been linked to increases in the number and severity of flares of Crohn disease, and smoking cessation can help achieve remission in patients with Crohn disease. Lactose intolerance is common in persons with Crohn disease or ulcerative colitis and can mimic symptoms of IBD.
