Foods to Avoid
Dairy foods increase the production of acid in the stomach. You don’t have to totally cut out such foods from your diet. You could reduce their consumption to three or less servings a day. Opt for low-fat or fat-free dairy products to effectively regulate stomach acid production.
Alcohol, as has been mentioned, aggravates gastritis. Black and red pepper, curry powder, hot peppers and chili are a strict no-no. If you stay away from them, you’ll see a positive effect on your gastritis.
Teas, cocoa, chocolate and colas should be avoided. Coffee increases the acidity level in your stomach.
Check to see if seasonings like cinnamon, garlic and cloves upset your stomach. Even if they don’t, limit their intake as a precaution. Peppermint, tomatoes, and citrus juices should also be reduced or eliminated from your diet if they cause stomach discomfort or heartburn.
Gas-producing foods like peas, broccoli, cabbage and some nuts should also be avoided or minimized, depending on how they affect your stomach.
