This is actually incorrect. The high fiber content of fruit can cause it to sit in the stomach longer, but only at most around twenty minutes, which is a good thing because this helps you feel more full and can help you lose weight and take in less of the more typically unhealthy foods. In fact the human body is designed to hold food in the stomach and slowly release it into the intestine to maximize intestinal digestion.

Furthermore, bacteria is what causes fermentation and rot, but bacteria can not survive in the extremely acidic conditions of the human stomach.

The truth is any time is a good time to eat fruit, before, during, or after meals. But most dietitians agree that eating it during the first portion of a meal is best, Because it slows digestion.
