Fruit digestion and storage: debunking common myths

Scientific insights clarify common misconceptions regarding fruit consumption and storage. Contrary to the belief that eating fruit after a meal causes it to ferment in the stomach, the digestive system processes all food contents together. The stomach mixes food with gastric juices, preventing rigid layers from forming, and moves contents progressively toward the small intestine.

Research published in The Journal of Nutrition indicates that the form of the fruit affects digestion speed; for instance, whole apples have a gastric emptying half-time of approximately 65 minutes.

Regarding food preservation, apples release ethylene, a natural plant hormone in gas form that accelerates ripening. Because of this, apples should not be stored near ethylene-sensitive produce such as broccoli or green salad, as the gas can cause these items to yellow or spoil more quickly.
