1 What to eat before the exam? Give full play to your brain. 1, properly supplement foods rich in vitamin A, vitamin B and lipids.
Nuts such as green or red vegetables, eggs, beans, sesame seeds, walnuts, peanuts and coarse grains such as millet.
2. Eat something to relieve tension.
It can supplement iodine-containing foods such as kelp, laver, shrimp and fish. The effective components in onion can dilute blood concentration, improve oxygen supply to the brain, and eliminate mental stress.
3, nuts can be eaten, don't eat too much.
Some people think that nuts like walnuts are very brain-healthy. In fact, it is not suitable to eat too many nuts before the exam. Because these hard fruit foods are high in oil, eating them in large quantities will cause candidates to get angry. So don't exceed 25 grams at a time.
1 Precautions before the exam 1. Eat less sweets.
In addition, foods with high blood sugar response are not conducive to brain thinking. Studies have long known that high-carbohydrate foods can increase the level of serotonin in the blood, which can promote sleep. It is found that even if a lot of rice is eaten, rice varieties with high blood sugar response will feel sleepy significantly earlier than rice varieties with low blood sugar response. Therefore, during the inspection, children should try to eat less sweets, sweet drinks and processed foods containing flavors and pigments.
Don't eat too much for lunch and dinner.
Studies show that people who eat more will feel more sleepy under the same food content. Therefore, Fan Zhihong suggested that children should eat 70% to 80% full lunch and dinner during the exam, so as not to affect their studies after meals. Add a small amount of extra meals between meals, especially fruits and yogurt.
Eating walnut fish oil before the exam is not helpful.
Because learning is "brain-dead", many parents will give their children brains. In addition to buying health products, they often give their children "brain-nourishing" foods such as walnuts and fish oil. Professor Fan Zhihong said that it is of no practical significance to eat fish oil to supplement DHA before the exam, because although the development of brain cells needs omega-3 fatty acids, brain cells have already developed in childhood, and cells will not proliferate for life.
In the days before the exam, no matter how much fish oil you eat, it is impossible for your brain to grow new cells. Although adequate intake of DHA is beneficial to infants and the elderly, for adults, no study has found that eating DHA for ten and a half months has any practical significance.
I recommend: pay attention to six points before the college entrance examination.
4. Don't eat big fish and big meat during candidates.
Some parents often eat big fish and big meat in order to supplement their children's nutrition during exams, which is called supplementing enough protein. Fan Zhihong said that amino acids in protein are really necessary, and many kinds of neurotransmitters need them to be synthesized, but people only need dozens of grams of protein a day, so there is no extra benefit from excessive supply. For girls who don't exercise much, two pieces of meat/fish, one egg, one glass of milk and 300 grams of food are enough.
