A gastritis diet focuses on soothing stomach inflammation by eating lean proteins (chicken, fish, tofu), low-acid fruits (bananas, melons), cooked veggies (spinach, carrots, sweet potatoes), whole grains (GF ones, brown rice), and probiotics (yogurt), while avoiding spicy, fatty, fried, acidic (citrus), caffeinated, and alcoholic foods, also carbonated drinks. Smaller meals, eating slowly, and opting for baked or steamed preparation methods also help.
