It is recommended to go to the canteen. After all, dormitory appliances are forbidden, and it is difficult to eat well in the dormitory without a small pot. However, once it is discovered, it will only be punished, and the bookstore has a single nutrition. Therefore, it is recommended to go to the canteen, which is rich in nutrition, which is very beneficial to college students' physique.

Three meals a day can provide the human body with the necessary nutrition and energy. In fact, the breakfast, lunch and dinner time.

Only by correctly grasping the time of three meals together can we really achieve the purpose of health preservation.

1: Eat breakfast late

Older people generally have shorter sleep time, and believe that "early to bed and early to rise is good for health". Therefore, many old people get up at five or six in the morning, and then rush to exercise after breakfast, which is actually wrong.

Because when you sleep at night, all other organs are "resting", and only the digestive system is still working quietly, so you can't take a break until morning.

The old people's physical function declines, and their digestive function becomes weak. In the morning, the gastrointestinal tract should rest for at least 2 hours before they can start working again.

Eating breakfast too early will interfere with gastrointestinal rest and make the digestive system tired. Over time, gastrointestinal diseases such as indigestion will occur.

In addition, the early morning is an important time for the human body to eliminate metabolites. Because of the decline of the function of various organs, the elderly need to eliminate wastes for a longer time. If they eat too early, metabolites will accumulate in the body.

Two: Eat less at lunch

What I said here is to eat less.

There are two meanings. One is that it is best to be full at seven or eight points, and never eat too much! Another layer is to eat less staple food!

An Australian expert's research shows that if people are always hungry, their life span will increase by 2%-3%.

If we eat too well and eat too much, it will only overload the body and cause a series of health problems. Among them, obesity bears the brunt. The foods with high fat and high protein that modern people often eat are more difficult to digest. Excess "nutrients" accumulate in the body, and the consequences are obesity and a series of diseases of wealth.

Therefore, after lunch, people will continue to devote themselves to their work, especially some white-collar workers who sit for a long time and exercise less. If they eat too much at lunch, they are more likely to become obese.

In addition, studies have proved that eating less staple food at lunch can prevent drowsiness in the afternoon.

At lunch, the gastrointestinal tract begins to digest food, and the blood will concentrate on supplying the gastrointestinal tract and absorbing nutrients, so the blood supply to the brain will decrease, and you will feel sleepy.

Especially when you eat too much carbohydrates at lunch, the glycemic index will be high, and the blood sugar in your body will rise rapidly and then fall, so people will feel weak and sleepy.

For Chinese people, it is normal to eat more rice and steamed bread for lunch. The calorie intake of carbohydrates represented by these staple foods has accounted for 2/3 of the total calorie intake of Chinese people.

But as everyone knows, the glycemic index of these foods is above 8, almost as high as sugar, which is the "culprit" that causes people to feel sleepy in the afternoon.

Therefore, if you want to stay awake in the afternoon, you should pay attention to lunch:

First, slow down the body's absorption of carbohydrates. Eat more foods containing protein, such as fish, eggs and bean products, and eat less carbohydrates, such as rice and other staple foods. A lunch composed of protein and vegetables plays a decisive role in keeping the brain sharp and awake.

Second, in the order of eating, you can eat soup first, then vegetables and staple foods, so that you can make your stomach feel full first, and then you won't overload your stomach.

Third, eat only eight points full, otherwise it will easily lead to brain hypoxia.

3: Eat dinner early

In life, many elderly people like to wait for their children to come home from work before eating together. Therefore, dinner is often delayed until seven or eight o'clock in the evening, but eating dinner at this time is very harmful to the health of the elderly.

First of all, the digestive function of food is declining when people enter old age. Old people have less nightlife. Generally, they finish their meals at seven or eight and go to bed before ten o'clock.

The body simply doesn't have enough time to digest food thoroughly, and it is prone to indigestion such as abdominal distension and constipation, which may also affect the quality of sleep.

If the water intake in dinner is high, getting up many times at night will also affect the sleep of the elderly.

Secondly, the peak time of calcium excretion is 4-5 hours after eating. If you eat dinner late, too close to your bedtime, and your body doesn't have enough time to excrete calcium through urination, it may lead to urinary calculi.

There are many young people who often go out for dinner at night or have a snack, which will lead to eating too late for dinner, which is very harmful to health!

Although it's called dinner, try to eat it as early as possible, and generally make sure to finish the dinner four hours before going to bed. Considering the different time and the length of the journey for everyone to get off work, it is more appropriate to have dinner between 6 and 8 pm.
