Precautions for breakfast principle: breakfast should follow the principle of low quantity, high quality and thinness, and pay attention to the collocation of main and non-staple foods.

In the morning, we can often see some office workers eating bread, steamed bread, cakes or biscuits while walking in a hurry.

After getting up in the morning, people's gastrointestinal function has not recovered from the state of inhibition at night to the state of excitement. The digestive function is also weak. Eating some "dry food" at this time is not only difficult to swallow, but also the human spleen is depressed in the morning. The gastric juice is not moist, and the secretion of various digestive juices is insufficient, which is not conducive to the digestion and absorption of food. After a night's sleep, people consume a lot of water and nutrition from urine, skin and breath, and are already in a semi-dehydrated state in the morning. Eat foods rich in water for breakfast, or drink some liquids before meals, such as warm water, soybean milk or hot milk. This can not only improve the water shortage in the body in time, but also be beneficial to gastrointestinal digestion and restore the body's metabolism to a vigorous state. It is beneficial to work and study during the day, and can also effectively prevent the sudden onset of cardiovascular and cerebrovascular diseases.
