In order to prepare for the unified examination, many students have to stay up late to study, but have to get up early in the morning to rush to school. This is a reflection of the life of today's students.

In addition to breakfast, lunch and dinner, most students often have the habit of eating late night snacks. Living such a stressful life, people feel like they are missing something if they don't eat, so they like to eat foods with a lot of sugar or starch, such as instant noodles, bread, and biscuits. In fact, studying and studying consume less calories than imagined. However, due to insufficient sleep time and excessive mental stress, the body will become imbalanced and prone to vitamin deficiency or mineral deficiency, as well as excessive intake of unnecessary nutrients. Sugar or starch will consume more vitamin B complex, so candidates should pay attention to taking in more vitamin B complex. Also, reading for a long time can cause eye fatigue, so you should also take in enough vitamin A. Of course, other vitamins such as C and E should also be taken regularly.

The unified examination is a short-term decisive battle. During this period, proper supplementation with multivitamin pills is also a way. However, the dosage must be carefully controlled to avoid side effects.

Generally speaking, during the examination period, the heat energy consumption is not large, but the spirit is in a state of high excitement and tension, and the digestion ability may be slightly reduced; in addition, the unified examination is mostly held in midsummer, the weather is hot, and people Water in the body is easier to dissipate. When arranging the diet, it should be based on the physiological characteristics of the candidate and the location and environmental conditions.

① Diet amount: You should not overeat, generally 70-80% full is appropriate to avoid stomach discomfort and affect the blood supply to the brain.

② Food selection: In terms of food, choose foods that are small in size, easy to digest and absorb, high in sugar, low in fat, containing inorganic salts and rich in vitamins. High-sugar, low-fat foods are easy to digest and can increase muscle glycogen reserves in the body, thereby improving the candidate's endurance. If you eat too much meat and don't supplement vegetables and fruits before the exam, your body fluids will tend to be more acidic. The acidity of the blood increases, making candidates prone to fatigue and affecting their performance. Therefore, parents of candidates should pay more attention to the combination of alkaline, neutral, and acidic foods (for questions about alkaline, neutral, and acidic foods, see Section 10 of this chapter "Changing Children's Acidic Physique").

③Drink water before the exam: The college entrance examination falls in midsummer, and candidates should prevent exhaustion to avoid affecting their performance or even interrupting the exam. Candidates should keep their bodies adequately hydrated 2-3 days before the exam. You can drink 100-200 ml of water before the exam.

④ Take sugar before the test: Taking sugar before the test can save the consumption of muscle glycogen and prevent the occurrence of hypoglycemia, improve endurance, and delay or reduce the occurrence of fatigue. Generally, it is appropriate to add about 50 grams of sugar before the test, but not too much.

⑤Drink coffee or strong tea before the exam. Both coffee and tea can cause nervous excitement. Taking a small amount of coffee before taking an exam has a certain effect on extending endurance, strengthening physical strength and increasing fat utilization. But pay attention to the dosage, and those who are sensitive to it must not take it.
