One can observe and identify foods that cause acidity, a burning sensation, vomiting, excessive gas, nausea, a feeling of heaviness and should avoid these. Alcohol, pepper, chilli, other spices, coffee, tea and colas should be avoided as these irritate the stomach linings. Food high in dietary fibre, vegetables, fruits and whole grains are good for the digestion. Caffeine-free drinks, low acid juices, such as apple, grape, or pear, mild herbal teas and water should be used as beverages.
Non vegetarian food produce toxins and should be avoided. Boiling, steaming and baking which use little or no fat/oil are the best way to cook food. How much you eat is important. A thumb rule for food intake is to eat just enough food that leaves you feeling hungry. If you feel satiated, you are unnecessarily taxing your stomach. Follow a sensible regime of eating moderate amount of locally available food which suits your taste, avoiding food that irritates your stomach. That is the best gastritis diet. Indeed it is the best diet for all conditions. You won’t ever need to see a doctor for this.
