The importance of the stomach to health goes without saying. If you don't take good care of it, even the best food will be tasteless, let alone absorbing enough nutrition. Taking care of the stomach requires accumulation over time, and more careful attention to diet. If your stomach is not in good condition, you can change three meals a day into five: breakfast, snack, lunch, snack, dinner. Studies have shown that regular meals can form a conditioned reflex, which is beneficial for digestion and absorption.
