Its nuts are delicious and the quality is the best among walnut trees. It can be eaten raw, fried or made into candy. No matter from the taste or nutrition, it has higher nutritional value than ordinary walnuts.
In fact, small walnuts can not only strengthen the brain and maintain beauty, but the latest research also found that eating walnuts regularly can lower cholesterol and protect the cardiovascular system.
A recent experiment conducted by Australian scientists proved that eating walnuts every day can lower human cholesterol. Liu, a member of the Collateral Diseases Branch of the Chinese Medicine Association and director of the Cardiovascular Department of Beijing Hospital of Traditional Chinese Medicine, said that walnuts are mainly rich in fat, and their lipid substances include linoleic acid glyceride, linolenic acid glyceride, oleic acid glyceride, etc., which is conducive to reducing the rise of cholesterol in the blood and is very helpful for the health care of patients with arteriosclerosis and cardiovascular and cerebrovascular diseases.
Chinese medicine has called walnuts "longevity fruit" since ancient times, and holds that walnuts can tonify the kidney and brain, tonify the middle energizer, and nourish the skin and blacken the hair. Zhang said that walnuts are most suitable for mental workers, especially white-collar women, because these people often overuse their brains and consume sad blood. Eating walnuts regularly can replenish the brain, improve brain circulation and enhance brain power. At the same time, it also has the effect of blackening hair and moistening skin. Because "hair is bleeding" and blood is black, walnuts are rich in vitamins, which can improve the physiological activity of human skin, so they are beautiful products for women. It is said that Mei Lanfang, a famous Peking Opera performer, ate walnut porridge every day before her death, so her skin was delicate and her face was smooth.
After we open the hard shell of walnut, we will find that the shape of walnut kernel is very similar to that of human brain, which is why many people further understand that walnut can replenish brain. Professor Zhang said: "This is called" seeking the same kind "or" taking the image of the same kind "in Chinese medicine. Traditional Chinese medicine itself is an empirical science, and it is a law summarized from long-term practical experience. Facts have proved that walnuts are really effective in nourishing the brain. " According to the research of modern nutrition, clean walnut kernel, after removing about 50% waste such as shell, contains 63% linoleic acid and 16.4% linolenic acid, and is rich in protein, phosphorus, calcium, vitamins and a lot of unsaturated fatty acids, which can enhance the elasticity of cerebral vessels, promote the vitality of nerve cells and improve the physiological function of the brain. Moreover, walnuts contain high phospholipids, which can maintain the normal metabolism of cells, enhance cell vitality and prevent brain cells from declining. In Japan, nutritionists advocate that school-age children eat 2 ~ 3 walnuts every day, which is very helpful for those children who are anxious, weak, tired of learning and slow to respond.
Walnut is a treasure, but also pay attention to how to eat, avoid eating. You should take it in moderation and stick to it for a long time. Although the fat contained in walnut kernel is unsaturated fatty acid, which is beneficial to remove cholesterol, the fat itself is high in calories. If you eat too much and can't make full use of it, it will be stored as cholesterol by the human body, and the result is counterproductive. Generally speaking, the daily weight of walnuts should be about 40 grams, which is equivalent to about four or five walnuts. At the same time, we should appropriately reduce the intake of other fats to avoid excessive calorie intake. Walnuts are very angry and contain a lot of oil. Eating too much will make people get angry and get sick. People who get angry and have diarrhea should not eat more.
A good way to eat is to make walnut porridge with red dates and rice, because walnuts can supplement the "innate foundation" and rice and red dates can supplement the "acquired foundation", which has the best health care effect;
Generally, raw food has high nutritional value;
