Eat a fruit whenever you feel like eating an unhealthy snack. Eat a fruit whenever you feel frustrated. Eat a fruit whenever you feel like you have achieved a goal. Fruit can be eaten at any time and it can be eaten along with other foods. The body produces digestive enzymes for protein, fat, and carbohydrates which help it digest mixed meals. Besides, since the stomach has a high concentration of hydrochloric acid, bacteria is killed before it is able to reproduce so fermentation cannot take place in the stomach , so don't worry about mixing fruits with your main meals like salads.
