In fact, it exaggerates the health care function of apple. Therefore, an apple a day keeps the doctor away, and there is not much scientific basis.

Moreover, if you only eat one apple a day, it is not in line with the concept of food diversification and balanced nutrition recommended by China's dietary strategy. China dietary strategy recommends eating every day? 250 ~ 350 grams of fruit, and try to diversify. Eating only one apple a day is not balanced, so you can't ignore other fruits.

The nutritional value of apples is still good! Although an apple a day can't keep the doctor away, eating apples still has many benefits and high nutritional value.

Apples contain dietary fiber, which can help the human body to discharge waste, promote intestinal activities, and moisten the intestines to relieve constipation. Apples contain vitamin C, which can also enhance physical strength and disease resistance, so you can eat them often.

Third, the precautions for eating apples Patients with nephritis, diabetes and ulcerative colitis should not eat apples. The crude fiber in apples can cause physical discomfort. Especially in patients with acute ulcerative colitis, it is easy to cause serious complications.

Apples are hard, so you should chew them slowly, so as not to affect the intestines and cause digestive problems. It is not advisable to eat apples immediately after meals. When the food is still being digested after a meal, eating apples immediately will increase the burden on the stomach and even lead to bloating, diarrhea and other inedible apple cores.

Although apples are rich in nutrition, we should eat less, only one a day, before meals.
