1. After breakfast: It is better to eat apples after breakfast. Apple itself has a laxative effect. Eating an apple after breakfast can promote gastrointestinal motility and expel feces from the body as soon as possible. But be careful not to eat apples on an empty stomach in the morning, because apples contain ingredients such as malic acid, which will damage gastrointestinal health if eaten on an empty stomach.

2. Half an hour before lunch: It is better to eat apples half an hour before lunch. Apples contain a lot of water and have relatively low calories. Eating an apple half an hour before a meal can make you feel full and reduce your lunch intake, which is helpful in controlling your diet.

3. One hour before going to bed: It is better to eat apples one hour before going to bed. Apples can eliminate bacteria in the mouth and help you sleep. Eating an apple one hour before going to bed can clean your mouth and improve the quality of your sleep.
