Apples are sweet and sour, rich in nutrients, and are good for the body. There is no specific time limit for eating apples, and they can be used at any time of the day. The best time to eat apples is in the morning after waking up and half an hour before meals. After sleeping at night, the water and sugar in the body will be consumed, and the body will lack nutrition after waking up in the morning, so any food can be absorbed by the body quickly. In addition, patients with diabetes and ulcerative colitis should limit their intake appropriately, while apples are hard in texture and should be chewed slowly to avoid stimulating the intestinal tract and causing digestive diseases.
