A person suffering from indigestion, abdominal pain, a burning sensation in the stomach and bloating should limit the intake of foods that are high in acidity, such as tomatoes and citrus fruits, according to WebMD. Avoiding spicy foods, alcohol and quitting smoking also help to prevent or alleviate indigestion.
Foods that can help reduce bouts of acid reflux and heartburn include oatmeal, rice, couscous and other complex carbohydrates, according to the Huffington Post. Ginger, fennel, poultry, fish and seafood are all excellent foods for acid reduction, as are all greens and root vegetables such as broccoli, asparagus and cauliflower. Some fruits, such as bananas and varieties of melon, generally help to reduce acidity, but may have an adverse effect in a small percent of the population.
