Eating fruits after a meal is a great thing to do, especially if they replace a high-calorie dessert. Fruits contain fiber, vitamins, minerals, and other health-promoting ingredients, especially when eaten fresh. For that reason, I would say that fruits do affect the body, but in a positive way. There is no reason to wait for a certain period of time after having a meal to eat fruit. Eating one fruit after every meal would make sure that you ate at least three fruits each day. (It is recommended that we eat 5-9 servings of fruit and vegetables per day.)
