The stomach’s “best friend” is not a single food—it is a meal structure that balances acid load and reflux risk. First: portion control. Large, high-fat meals slow gastric emptying and can worsen reflux/indigestion. Second: consistent meal timing and eating slowly. Third: a balanced fiber–protein pattern, adjusting spices and fat based on personal tolerance. Fourth: reduce alcohol and smoking, and avoid late meals (ideally finish eating 2–3 hours before bed). Fifth: know your triggers—chocolate, peppermint, coffee, tomato/citrus, and fried foods can worsen reflux for some. A stomach-friendly approach is also gut-friendly: better digestion upstream reduces irritation downstream. If you have persistent burning, swallowing difficulty, weight loss, or bleeding, prioritize medical evaluation over “magic foods.” Supplements should be goal-driven and time-limited; lifestyle structure is the foundation.
