What should middle school students eat to stay alert

In this season, people are prone to sleepiness when working or studying, or even when resting at home, because many people's mental state is like this. They will feel very sleepy in an extremely quiet or extremely busy environment. Especially many middle school students are in the tense stage of the exam. Once they feel sleepy, it may affect their listening in class, which will cause a lot of harm to the body. What middle school students can eat to refresh themselves has become a concern for parents.

1. Beans

Iron is the main medium for producing human energy, and it is responsible for the important task of transporting oxygen to human organs and muscles. Therefore, if the human body lacks iron, it will lead to anemia, making people feel dizzy and weak.

Although pork liver and lean meat are the best sources of iron, eating red beans, black beans or soybeans regularly can also supplement iron and effectively improve symptoms of fatigue and weakness.

2. Spinach

Spinach contains magnesium, a mineral that women are more likely to lack. If women consume less than 280 mg of magnesium per day, they will feel tired. The role of magnesium in the human body is to convert carbohydrates in the muscles into usable energy.

3. Banana

Bananas are known as "high-energy foods" because they contain carbohydrates that are easily absorbed by the human body and are also rich in potassium. Potassium can help maintain normal muscle and nerve function in the human body, but it cannot be stored in the body for a long time. After strenuous exercise, the potassium level in the body will drop to a very low level. Studies have shown that low potassium can cause muscle pain, irregular heartbeat, slow reaction, etc., and eating a few bananas can make up for the potassium deficiency.

4. Strawberries

5. Tuna

Among high-protein fish, tuna is rich in tyrosine, which helps produce neurotransmitters in the brain, allowing people to concentrate and think quickly.
