The nutritional value of walnuts and the benefits of eating walnuts

When it comes to walnuts, many people can still recall the time when they ate walnuts before exams to "nourish the brain". In fact, small walnuts can not only improve brain health and beautify the skin, but the latest research also found that eating walnuts regularly can lower cholesterol and protect cardiovascular health.

Nutritional value of walnuts

According to experts, walnuts have high nutritional value. According to analysis, every 100 grams of walnuts contain 14.9 grams of protein, 58.8 grams of fat, 9.6 grams of carbohydrates, 9.6 grams of dietary fiber, 30 micrograms of carotene, 43.21 milligrams of vitamin E, 385 milligrams of potassium, 3.44 milligrams of manganese, 56 milligrams of calcium, 294 milligrams of phosphorus, 2.7 milligrams of iron, 4.62 micrograms of selenium, and 2.17 milligrams of zinc. Walnuts are among the heart-strengthening foods recommended by Dr. Morrison, a contemporary master of natural therapy. According to measurements, every 100 grams of walnuts contains 20-64 grams of fat, 71% of the fat in walnuts is linoleic acid, 12% is linolenic acid, and the protein is 15-20 grams. The protein is also high-quality protein. The fat and protein in walnuts are the best nutrients for the brain. The carbohydrates are 10 grams, and it contains nutrients such as calcium, phosphorus, iron, carotene, riboflavin, vitamin B6, vitamin E, juglone phylloquinone, phospholipids, and tannins.

Benefits of walnuts

Walnuts are mainly rich in fat, the lipids they contain include linoleic acid glycerides, linolenic acid and oleic acid glycerides, which are beneficial for reducing the increase of cholesterol in the blood and are very helpful for the health of patients with arteriosclerosis and cardiovascular and cerebrovascular diseases.

Chinese medicine has called walnuts "longevity fruit" since ancient times, believing that walnuts can nourish the kidneys and brain, replenish qi, moisturize the skin, and blacken hair. Zhang Hude, a professor at the Health Care Room of Beijing University of Chinese Medicine, said that walnuts are most suitable for brain workers, especially white-collar women, because these people often overuse their brains and consume a lot of heart and blood. Eating walnuts regularly can nourish the brain, improve brain circulation, and enhance brain power. At the same time, it can also blacken hair and make the skin smooth, because "hair is the residue of blood", and blood is strong, so it turns black. Walnuts are rich in various vitamins, which can improve the physiological activity of human skin, so they are a good beauty product for women. It is said that the famous Peking Opera performer Mei Lanfang ate walnut porridge every day during his lifetime, so his skin was stretched, tender, and his complexion was smooth.

When we open the hard shell of walnut, we will find that the shape of walnut kernel is very similar to human brain. Many people know that walnut can nourish the brain. Professor Zhang said: "This is called 'like attracts like' or 'like draws like' in Chinese medicine. Chinese medicine itself is an empirical science, which is a law summarized based on long-term practical experience. Facts have proved that walnut is indeed very effective in nourishing the brain." Modern nutrition research believes that the net kernel of walnut after removing about 50% of the shell and other waste contains 63% linoleic acid, 16.4% linolenic acid, as well as rich protein, phosphorus, calcium and multiple vitamins. It contains a large amount of unsaturated fatty acids, which can strengthen the elasticity of cerebral blood vessels and promote the vitality of nerve cells, and improve the physiological function of the brain. In addition, walnuts contain a high content of phospholipids, which can maintain normal cell metabolism, enhance cell vitality, and prevent brain cell decline. In Japan, some nutritionists advocate that school-age children eat 2 to 3 walnuts a day, which is very helpful for those children who are restless, weak, hate learning and slow to react.

Walnut is a treasure, but it also pays attention to the way to eat and the taboos. Director Liu believes that it should be taken in moderation, for a long time, and with persistence. Although the fat contained in walnut kernels is unsaturated fatty acids that are beneficial to the removal of cholesterol, the fat itself has a high calorie content. If it is consumed in excess and cannot be fully utilized, it will be stored by the human body as cholesterol, which will have the opposite effect. Generally speaking, the weight of walnut kernels taken every day should be around 40 grams, which is approximately equivalent to four or five walnuts. At the same time, other fat intake should be appropriately reduced to avoid excessive calorie intake. Professor Zhang said that walnuts are hot and contain a lot of oil. Eating too much will make people get angry and nauseous. People who are getting angry or having diarrhea should not eat them. A good way to eat is to boil walnut kernels, red dates, and rice together into walnut porridge, because walnuts can replenish the "innate foundation", and rice and red dates can replenish the "acquired foundation". This combination has the best health care effect.

According to research by domestic and foreign experts in nutrition and medicine, walnut oil is rich in up to 90% of various unsaturated acids, among which linoleic acid is relatively high, which is 3 to 4 times the content of ordinary rapeseed oil. Linoleic acid is an essential fatty acid for the human body. If essential fatty acids are lacking, all systems of the human body will be abnormal. However, the human body cannot synthesize linoleic acid by itself and must rely on intake from food, while general edible vegetable oils such as rapeseed oil cannot supply the linoleic acid that the human body needs normally. Therefore, regular consumption of walnut blended oil can increase the level of high-density lipoprotein, transport cholesterol to the liver for metabolism and excretion, thereby preventing the formation of cholesterol. At the same time, walnut oil can also prevent and treat many common "rich diseases" such as hypertension, hyperlipidemia, diabetes, and obesity.

The health benefits of walnuts

The linoleic acid, glycerol and linolenic acid in walnuts can reduce the absorption of cholesterol in the intestine, promote the degradation of cholesterol in the body into bile acid in the liver, and excrete it with bile, which is beneficial for patients with arteriosclerosis, hypertension and coronary heart disease. Vitamin B6 in walnuts can help regenerate damaged hearts. Folic acid in walnuts also helps maintain myocardial metabolism; bone-enhancing acetic acid in walnuts can dilate coronary arteries, excite the heart, and enhance myocardial function; it can treat insomnia and neurasthenia. Walnuts are rich in phospholipids, which are one of the main components of cell structure. Sufficient phospholipids can enhance cell vitality and play an important role in hematopoiesis, promoting delicate skin, wound healing and hair growth. Walnuts contain a lot of zinc, manganese, chromium and other trace elements. Zinc, manganese, chromium and other trace elements are indispensable to the human body. Zinc and manganese are key components of the endocrine glands of the human body such as the pituitary gland, pancreas and gonads. More importantly, walnuts can delay the aging of cranial nerves and have the greatest benefit to cranial nerves. They are a good product for improving intelligence, strengthening the brain and strengthening the body. As early as the Sui and Tang Dynasties, people ate a lot of walnut kernels before taking the exams in order to get good results in the imperial examinations. At that time, they only knew its effect but not its principle. In fact, this is because walnuts contain lecithin, vitamins and trace elements. Some people call walnuts the "brain-enhancing god."

Benefits of eating walnuts

Walnuts are warm in nature, sweet in taste, non-toxic, and have the effects of strengthening the stomach, nourishing the blood, moistening the lungs, and nourishing the mind. They are a good fruit for food therapy. Walnuts contain a lot of fat and protein, and this fat and protein are easily absorbed by the human body. The nutritional value of 1 jin of walnut kernels is equivalent to 5 jin of eggs or 9 jin of milk. The protein it contains contains lysine, which is extremely important for the human body and is extremely beneficial to the nutrition of brain nerves. Whether you are in good health or not, eating walnuts regularly can not only strengthen your body, but also drive away the troubles of diseases.
