Many people think that puzzle games are helpful for brain-nourishing. In fact, eating the right things can achieve the same effect. Recently, Haramarano, a famous American psychologist and columnist of Psychology Today magazine, recommended ten kinds of brain-nourishing foods. They all help to protect delicate brain cells and prevent the damage to blood vessels caused by aging. Of course, different countries have different food structures. This menu is for reference only. < p>
1 spinach <; p>
Spinach has strong antioxidant capacity, which helps to slow down cognitive impairment and central nervous system damage caused by age. Spinach is a leader in containing antioxidants vitamin C and vitamin E, which is especially beneficial to the elderly. Scientists at the Nutrition Research Center for the Elderly in Boston, USA, recently gave eight elderly women spinach extract. The results showed that the extract had "strong antioxidant activity", which could improve their antioxidant capacity by 2%, which was equivalent to taking 125 mg of vitamin C. < p>
2 dark green leafy vegetables < p>
The metabolism of food in protein will produce a substance called cysteine, which is harmless to the body, but too high a content will cause cognitive impairment and heart disease. Moreover, once cysteine is oxidized, it will have toxic and side effects on the arterial wall. Vitamin B6 or B12 can prevent the oxidation of cysteine, and the vitamin content in dark green leafy vegetables is the highest. < p>
3 salmon <; p>
Fish fat contains omega-3 fatty acids, which can protect the nervous system and help to strengthen the brain. Studies have shown that people who eat fish at least once a week, especially salmon, sardines and herring, have a much lower incidence of Alzheimer's disease than those who seldom eat fish. Eating fish also helps to strengthen the activity of nerve cells, thus improving the ability of learning and memory. < p>
4 grape juice or wine < p>
drinking grape juice often is beneficial to prolong life. Drinking wine properly has the same effect, but because alcohol can paralyze nerves, grape juice is a better choice. The antioxidant content of grape juice is higher than that of any other fruits and vegetables, and it can improve the transmission ability of nervous system. Besides prolonging life, grape juice can also improve memory in a short time. < p>
5 hot cocoa <: p>
Hot cocoa not only warms the body, but also is effective for strengthening the brain. The content of antioxidants in drinks made from two teaspoons of pure cocoa powder is almost twice that of red wine, three to four times that of green tea and four to five times that of black tea. Antioxidants in cocoa can protect brain cells and prevent neurological disorders. < p>
6 whole wheat products and brown rice < p>
The best way to enhance the body's nutrient absorption capacity is to eat brown rice. Brown rice contains various vitamins, which is very important for maintaining cognitive ability. Among them, vitamin B6 is the most effective for reducing the level of cysteine. Americans seldom eat "coarse grains", which is one of the reasons for their insufficient intake of vitamin B6. < p>
7 almonds and walnuts < p>
Dried fruits, especially almonds and walnuts, are common foods at parties. They are not only delicious, but also rich in antioxidants. Almonds and walnuts have more obvious effects because they contain omega-3 series fatty acids. This coincides with China's statement that "eating walnuts to nourish the brain". < p>
8 olive oil <; p>
The main causes of cerebral arteriosclerosis are long-term consumption of high-calorie and high-fat (saturated fatty acid) foods and lack of essential nutrients. It is found that the residents of Mediterranean countries have a low incidence of cardiovascular and cerebrovascular diseases, which is related to their eating more olive oil in their diet. Olive oil contains a variety of unsaturated fatty acids, which can prevent atherosclerosis. Therefore, it is recommended to add some vegetable oils such as olive oil and safflower oil to cooking oil. < p>
9 garlic <; p>
The energy source of brain activity mainly depends on glucose. In order to make glucose play its due role, it is necessary to have enough vitamin B1. Garlic itself does not contain a lot of vitamin B1, but it can enhance the effect of vitamin B1, because garlic can produce a substance called allimine with B1, and the effect of allimine is much stronger than that of vitamin B1. Therefore, eating garlic properly can promote the transformation of glucose into brain energy. < p>
1 blueberry fruit < p>
Wild blueberry fruit is rich in antioxidants, which can remove impurities in the body. The experimental results in mice show that long-term intake of blueberry fruit can accelerate the growth and differentiation of neurons in the hippocampus of the brain, improve memory, prevent balance and coordination from weakening with age, and reduce the incidence of hypertension and stroke.
