Basically, it is better to eat fruit between meals, 2 hours after meals and 1 hour before meals. There is an English proverb that "the fruit in the morning is gold and silver from noon to 3 pm, copper from 3 pm to 6 pm, and lead after 6 pm". Eating fruit in the morning can help digestion and absorption, which is conducive to laxative. Moreover, the sweet and sour taste of fruit can make people refreshed and contribute to a good mood all day. On the contrary, eating fruits before going to bed is not conducive to digestion, especially fruits with high fiber content, which is even more harmful to health for people with poor gastrointestinal function. Eat less cool melons before going to bed.
