From a nutritional point of view, the human body needs carbohydrates, minerals, protein and other nutrients. If you eat "fruit" for a long time, it will have adverse effects on the endocrine, digestion and immune system of the human body. Fruit is indeed rich in vitamins and minerals, as well as bioactive substances beneficial to human health, such as carotenoids, bioflavonoids, anthocyanins and proanthocyanidins, organic acids and so on. Other nutrients needed by human body, such as protein, which is necessary for life, are very low in fruits. Therefore, experts from China Education Alliance Network suggest:

1, let the fruit become a supporting role. It's okay to have a fruit meal once in a while, not every day. Eat some cereal in moderation for lunch. You can choose a fish or meat as the main course with some green vegetables. Then, eat a yogurt or fruit salad as a supplement after lunch.

2, only eat eight points full. After lunch, the blood in the body will be concentrated in the stomach to help digestion and absorption, during which the brain is in a state of ischemia and hypoxia. Eating too much will prolong the time when the brain is in a state of ischemia and hypoxia, thus affecting the work efficiency in the afternoon.
