Walnut is a good diet. Phospholipids in walnuts have good health effects on the cranial nerves. Walnut oil contains unsaturated fatty acids that have the effect of preventing arteriosclerosis. Walnut contains zinc, manganese, chromium and other essential trace elements. The antitussive and antiasthmatic effects of walnut kernels are also very obvious. In the winter, they have excellent curative effects on patients with chronic bronchitis and asthma.
In order to have a smart little baby, many expectant mothers will consciously eat more walnuts during pregnancy. Some pregnant women eat 10 to 20 walnuts every day, and another can eat half a catty of small walnuts. But in this way, because of the high fat content of walnuts, eating too much will inevitably cause the body to gain weight due to excessive calorie intake, thereby affecting the normal blood sugar, blood lipids and blood pressure of pregnant women. Therefore, the following points should be noted when eating:
1. It should be taken in an appropriate amount for a long period of time.
Although the fat contained in the walnut kernel is an unsaturated fatty acid that is beneficial to the removal of cholesterol, the fat itself has a high calorie content. If it is used excessively and cannot be fully utilized, it will be stored by the human body as cholesterol, and the result is counterproductive. In general, the weight of walnuts taken every day should be about 20-40 grams, which is equivalent to about 4-5 walnuts. At the same time, other fat intakes should be appropriately reduced to avoid excessive calorie intake.
2. Peel the surface of the walnut skin.
Some people like to peel off the thin brown skin on the surface of walnuts, which will lose some of the nutrition, so do not peel off this layer of thin skin.
3. People who should not eat walnuts.
Walnuts are flaming, contain many oils, and eating too much can make people get angry and disgusting. Those who are getting angry and suffering from diarrhea should not eat it.
U.S. Finds that Men Eat a Handful of Walnuts a Day May Improve Sperm Quality
According to a recent report by the US “Doctor of Medicine Onlineâ€, a new study published in the journal Reproductive Biology of the American Reproductive Biology Society magazine found that men eat a handful of walnuts each day to improve sperm quality.
Researchers at the University of California, Los Angeles School of Public Health divided subjects into two groups, one normal diet and the other 75 grams walnuts per day. Before and after the experiment, the researchers extracted sperm samples from all participants and compared the sperm concentration, vigor, shape and size, and chromosome abnormalities. As a result, only the men in the "Walnut" group had significantly improved sperm quality.
Dr. Wendy Robbins, the head of the new study, said that the content of omega-3 fatty acids in walnuts is considerable. A number of male infertility studies have found that omega-3 fatty acids can improve sperm quality. This fatty acid and other polyunsaturated fatty acids play a pivotal role in improving sperm maturation and sperm membrane function.
