Plant food is rich in vitamins and so on. Among them, vitamin C can enhance resistance, and vitamin B 1 and nicotinic acid are indispensable substances for glucose metabolism, which directly affect the energy demand of the brain. These plant foods belong to alkaline foods and play an important role in maintaining the acid-base balance of the body. Therefore, eat 200-300g of fresh vegetables and 200-400g of fruit every day.
Supplementing protein food.
35% of brain cells are made up of protein. During the preparation period, high-quality protein should be supplemented to ensure physical needs. Eat meat 100g, fish and shrimp over 50g, bean products 100g, milk and dairy products over 200ml every day.
Enjoy your breakfast.
No matter how busy you are, you should eat a good breakfast, because the energy needed by the human body mainly comes from sugar. After getting up in the morning, the stomach is empty and the blood sugar level is low. If you don't eat or eat low-quality breakfast, and there is not enough blood sugar in your body to consume, people will feel tired, weak and slow.
As the examination period approaches, it is useless to "replenish the brain" too much.
There is less than a month before the college entrance examination. Many parents try their best to buy various supplements for their children, hoping to improve their intelligence and make their children's brains smarter and more flexible than usual by what medicine, health care products or nutrients they eat before the exam. This is actually ineffective and will increase their mental stress.
What parents can do is: give candidates more chin, vitamin C, beta-carotene, and minerals with antioxidant effects such as selenium, zinc and manganese to eliminate free radicals in the body and improve their antioxidant capacity.
The trace element beneficial to intelligence is mainly zinc.
Reminder around:
Foods rich in zinc are: meat, liver, eggs, corn, carrots, pumpkins, eggplant, Chinese cabbage and so on.
Candidates who stay up late should not drink coffee.
Although coffee can refresh you, it will accelerate the consumption of B vitamins. A small amount of sweets can bring relaxation and satisfaction, but too much will lead to the loss of minerals such as magnesium. At the same time, eating too much sugar will stimulate insulin secretion, lead to lower blood sugar, affect brain activity, and even make people sleepy. If candidates need to stay up late to study, it is best to eat more foods rich in vitamin B family for dinner, such as whole grains, lean meat, liver and beans. Yeast powder is also a good source of vitamin B family.
Reminder around:
Around midnight is the best time for protein synthesis in the brain. Long-term study staying up late will lead to cerebral dystrophy. Therefore, we should eat lean meat, eggs, tofu and other high-quality protein.
Children with poor sleep drink milk or a bowl of lotus seed and jujube soup before going to bed.
Children with depressive symptoms should eat more bananas, walnuts and chicken. These foods contain B vitamins and folic acid, which helps to improve symptoms.
Eat less cold food before the exam.
Don't eat cold food, in addition to worrying that summer food is easy to deteriorate and cause digestive tract diseases, you are also worried that candidates' digestive ability will weaken under tension.
