I think health preservation is nothing more than two aspects, and it is two verbs, one is to eat and the other is to move. Let's start with food. For example, China people's eating habits from ancient times to the present are breakfast, lunch and dinner, among which breakfast is the most important. There is a saying that breakfast should be eaten well, lunch should be full, and dinner should be eaten less. This may be the way to keep fit. Breakfast is about 12 hour from the last meal. Normally, it should be. At this point, all the glycogen nutrients in your body are consumed, and your brain needs blood supply. So if you don't eat breakfast the next morning, your brain can't supply nutrition, so your reaction will be slow, which will affect your morning. Moreover, breakfast should pay attention to balanced nutrition. Nowadays, many people's breakfast is gradually westernized, and two pieces of bread are directly in a box of milk, even if breakfast is solved. This is definitely impossible. These can't provide the nutrition the human body needs at all. These can be said to be snacks, even the fried dough sticks or biscuits that some of us often eat for breakfast are not allowed. Breakfast should be nutritious, with protein, some vitamins and, more importantly, carbohydrates. For example, you can eat eggs and whole wheat bread. Remember, it must be whole wheat bread, which is different from that kind of bread with sugar. Or drink soy milk or milk, be sure to eat vegetables, preferably with meat. If you have enough time, you can squeeze a cup of fruit and vegetable juice to supplement both vitamin C and cellulose. If you do, this is a nutritious breakfast. Noon is a transition. I have to work half a day in the morning and half a day in the afternoon, so I have to eat well at noon. Usually, I have to eat meat, vegetables and soup for lunch. For example, chicken, beef and mutton with some vegetables, such as lettuce, carrots, Chinese cabbage, mushrooms and broccoli, are enough to supplement nutrition. Eat light dinner, don't eat too greasy, don't eat too much, to avoid increasing the burden on the gastrointestinal digestive system. In this case, it is easy to sleep well at night, so eat less spicy food at night, and don't eat some foods that are easy to cause flatulence, such as potatoes and sweet potatoes. As for sports, we need to persist. Now advocate walking every day 10000. You can do more exercise in your daily life, such as doing housework. And if you live on a floor that is not very high, you can take the stairs. You can get up early every day, especially running, and you can go swimming in your spare time.
