Dark green leafy vegetables
The metabolism of protein foods produces a substance called homocysteine. This substance is not harmful to the body in itself, but excessive levels can cause cognitive impairment and heart disease. Moreover, once oxidized, homocysteine can have toxic effects on the arterial walls. Vitamin B6 or B12 can prevent the oxidation of homocysteine, and dark green leafy vegetables have the highest vitamin content.
Fish
The fat in fish contains omega-3 fatty acids, which have a protective effect on the nervous system and are beneficial for brain health. Studies have shown that people who eat fish at least once a week, especially salmon, sardines, and mackerel, have a much lower incidence of Alzheimer's disease compared to those who rarely eat fish. Eating fish also helps to enhance the activity of nerve cells, thereby improving learning and memory abilities. Whole grains and brown rice The best way to enhance the body's nutritional absorption is to eat brown rice. Brown rice contains various vitamins that are essential for maintaining cognitive function. Among them, vitamin B6 is most effective for lowering homocysteine levels.
Garlic
The main source of energy for brain activity is glucose. For glucose to function properly, a sufficient amount of vitamin B1 must be present. Garlic itself does not contain a large amount of vitamin B1, but it can enhance the effect of vitamin B1 because garlic can react with B1 to produce a substance called "allithiamine," whose effect is much stronger than that of vitamin B1. Therefore, eating garlic in moderation can promote the conversion of glucose into brain energy.
Eggs
The protein contained in eggs is one of the best-quality proteins in natural foods. It is rich in amino acids that the human body needs. In addition to being rich in lecithin, the egg yolk is also rich in calcium, phosphorus, iron, and vitamins A, D, B, etc., making it suitable for people with mental work.
Legumes and their products
They provide high-quality protein and 8 essential amino acids, all of which help to enhance the function of cerebral blood vessels. In addition, they contain lecithin, rich vitamins, and other minerals, making them particularly suitable for people with mental work. Soybean fat contains 85.5% unsaturated fatty acids, of which linolenic acid and linoleic acid are abundant. They have the effect of lowering cholesterol in the human body and are particularly beneficial for middle-aged and elderly mental workers to prevent and control cardiovascular and cerebrovascular diseases.
Walnuts and sesame
Modern research has found that these two substances are very nutritious, especially with a high content of unsaturated fatty acids. Therefore, eating them often can provide the brain with sufficient small-molecule unsaturated fatty acids such as linoleic acid and linolenic acid to remove impurities from blood vessels and improve brain function. In addition, walnuts contain a large amount of vitamins, which are very effective in treating neurasthenia, insomnia, relaxing the tense state of brain nerves, and eliminating brain fatigue.
Fruits
Pineapple is rich in vitamin C and the important trace element manganese, which helps to improve human memory; lemon can improve a person's receptivity; bananas can provide the brain with the important substance tyrosine, and tyrosine can make people energetic, concentrate their attention, and improve their creativity.
