There are many fresh walnuts in supermarkets and streets now. However, eating walnuts is also very particular. Four or five walnuts a day is enough, but it is best to stick to it for a long time. This is the best support for the body. Let's listen to the advice of experts.
Walnuts make up the brain. That makes sense.
Miss Zhang likes eating walnuts, but she just likes it. She doesn't believe her mother's statement that walnuts supplement the brain. "My mother said that walnuts look like brain flowers, so it is because of this brain. I don't think it is established. " However, Zhang's point of view does have rules to follow.
There is a saying in Chinese medicine that "people of the same kind want each other", that is, Ms. Zhang's insistence on looks can make up for it. Traditional Chinese medicine itself is an empirical science, and it is a law summed up 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 restless, weak, tired of learning and slow to respond.
Most suitable for mental workers
What are the benefits of eating walnuts? Linoleic acid and linolenic acid in walnuts can increase the level of high density lipoprotein, transport cholesterol to the liver for metabolism and excretion, and play a role in lowering blood cholesterol. Walnut contains a lot of vitamin E, which can enhance the vitality of human cells and is unique in preventing arteriosclerosis and delaying human aging.
Walnut also contains zinc, manganese, chromium and other indispensable trace elements, which are closely related to keeping the heart strong, maintaining normal endocrine function and resisting aging. In addition, walnut phospholipids can also enhance cell vitality, promote hematopoiesis, make skin smooth and delicate, promote wound healing, hair growth, improve brain nerve function, enhance digestion, and enhance the body's disease resistance.
Chinese medicine has called walnuts "longevity fruit" since ancient times. Experts believe that walnuts are most suitable for mental workers, especially white-collar women, because these people often use their brains too much and consume a lot of energy. 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.
It is not advisable to eat more at a time.
Many women have a big appetite after learning about the benefits of walnuts. It is not a good habit to buy one or two kilograms and clean them in a day or two. Walnuts should be taken in moderation for a long time, and they should not be "concentrated for a few days".
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, which is counterproductive and affects digestion. 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.
Chinese medicine also believes that walnuts are 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 it. A good way to eat is to make walnut porridge with walnuts, red dates and rice, because walnuts can supplement the "innate foundation" and rice and red dates can supplement the "acquired foundation". This combination has the best health care effect.
For fresh walnuts, the skin outside the kernel is bitter, and many people peel it, but there is a saying that this skin is nutritious and it is recommended to soak in water.
