5 foods people with Crohn's disease should avoid

Processed foods with unhealthy fats and sugary drinks can trigger inflammatory bowel symptoms.

Crohn's disease is a chronic inflammatory condition of the digestive tract that can deeply affect the intestinal wall, causing abdominal pain, persistent diarrhea, fever, fatigue, loss of appetite, and weight loss. A healthy diet and lifestyle help control symptoms and reduce the risk of recurrence. Conversely, foods high in saturated fat, sugar, or processed items can worsen symptoms for some patients.

Spicy foods like chili, pepper, and mustard contain high levels of capsaicin. This compound is a common trigger for Crohn's symptoms, as it can cause inflammation and inhibit stomach acid production, leading to issues such as reflux, nausea, and diarrhea.

Individuals with Crohn's disease should minimize added sugar and sugary foods to help improve their symptoms. Sugar can increase bowel motility, reduce nutrient absorption, and create an an environment for harmful bacteria to thrive. Excessive sugar intake may also stimulate inflammation, exacerbating inflammatory bowel symptoms.

Fried foods and meals high in fat, including large amounts of cream, butter, or oil, are detrimental for Crohn's patients. These can lead to abdominal pain, bloating, and diarrhea. The unhealthy fats in such foods are often not fully absorbed in the small intestine. Furthermore, saturated fats found in fast food can contribute to fat accumulation, increasing the risk of inflammation.

Lactose-containing dairy products can be problematic. Intestinal inflammation caused by Crohn's disease often makes lactose digestion difficult, resulting in bloating, indigestion, and digestive upset. Lactose is a sugar present in milk and other dairy products. Patients should explore alternative sources of calcium and vitamin D, such as soy milk, almond milk, or rice milk.

Red meat and processed meats can also aggravate Crohn's symptoms. Red meat's high saturated fat content can promote inflammation, triggering disease flare-ups. Moreover, processed meats often contain numerous spices and preservatives that can elevate blood sugar levels, negatively impacting gut health. Crohn's patients should opt for lean red meat to provide essential protein while limiting inflammatory fats.
