What kind of food is better for children to eat to nourish their brains before the high school entrance examination?

It is common to see middle school students rushing home after school to do their homework and review their lessons. The heavy study pressure makes them almost breathless, but they have to work hard to overcome it in order to prepare for the high school entrance examination. However, long-term use of the brain will make them feel physically and mentally exhausted, and in severe cases it will affect their height growth. Therefore, it is very necessary for them to supplement their brains. So what should children eat to supplement their brains better for the high school entrance examination? Let me give you a detailed answer in the following time.

Nutritional principles

1. Carbohydrates: The three energy-producing nutrients of carbohydrates, proteins and fats are appropriate.

2. Protein: Neurotransmitters that maintain various brain activities and participate in nerve conduction are composed of or derived from amino acids in protein.

3. Fat: The protein and gray matter in the brain contain a large amount of sphingomyelin, which is synthesized by essential fatty acids.

4. Minerals: Inorganic salts such as calcium, zinc, iron, copper and iodine play an important role in the brain's learning and memory, the excitability of the central nervous system, and oxygen supply to the brain.

5. Vitamins: Mental workers need rich vitamin A, vitamin B1, vitamin B2, vitamin B6, folic acid and vitamin C, etc.

Suitable food

1. Staple foods and beans: Choose foods rich in minerals such as wheat, japonica rice, black rice, and black sesame.

2. Meat, eggs and milk: pig heart, pig brain, pig marrow, milk, beef marrow, sheep kidney, donkey meat, pigeon meat, sea bass, mandarin fish, yellow croaker, hairtail, bighead carp, sea cucumber and other foods rich in protein and vitamins.

3. Vegetables: Choose foods rich in vitamins such as cabbage, yam, taro, enoki mushrooms, shiitake mushrooms, and carrots.

4. Fruits: Choose foods rich in fat and protein such as lotus seeds, lilies, longan meat, sour dates, jujubes, mulberries, raisins, and lychee meat.

5. Others: beans, eggs, milk, fish, walnut kernels, sesame seeds, honey, corn, millet, fungus, day lily, and enoki mushrooms.

Dietary taboos

1. People who are used to eating salty food will not only develop high blood pressure, arteriosclerosis and other diseases, but also damage the arteries, affect the blood supply to the brain tissue, and cause the brain cells to be in a state of ischemia and hypoxia for a long time, resulting in mental retardation, memory loss, and even premature aging.

2. Excessive lead content in food can damage the brain and cause mental retardation. Foods include: popcorn and preserved eggs contain lead oxide and lead salts. Lead has a strong penetrating ability.

3. Foods containing aluminum can cause memory loss and slow thinking ability, so fried dough sticks should not be the staple food for breakfast. If you often use aluminum pots to cook or aluminum kettles to boil water, you should also pay attention to the problem of increased aluminum intake.

The above content is the detailed explanation I have made for everyone. I believe that parents and friends also have a correct answer to the question of what food should be eaten to better nourish the brain for their children before the high school entrance examination. In addition, I would like to remind my friends that the pressure on children to take the high school entrance examination is very high, so we should communicate more with them and help them release pressure and relieve tension. Let the children maintain a calm mind to take the high school entrance examination.
