Three doubts about walnuts

1. Is it true that walnuts are good for the brain?

The so-called "replenish brain" is not a scientific concept, and there is no scientific basis for the argument of "eat what repair what". But it cannot be completely denied that compared with other nuts, walnuts may have a slight advantage in terms of nervous system health. Walnuts contain a small amount of omega -3 fatty acids, which can be converted into DHA (docosahexaenoic acid) in the body to help brain health. Walnuts contain sphingomyelin, which is one of the structural substances that make up the nervous system. Walnuts are also rich in polyphenols. Its intake can help reduce the inflammation of brain cells and improve the transmission between neurons. It is related to the improvement of memory, cognitive flexibility, information processing speed and overall cognitive function.

It is beneficial to prevent cognitive deterioration in middle-aged and elderly people. But for tired young people, there is no research evidence that whether eating walnuts can strengthen their brains currently. It can only be said that walnuts and other nuts are part of a healthy diet, and a healthy diet can help people play better work efficiency.

2. Is it true that walnuts are good for preventing diabetes ?

Although few people mention it, this statement is not unfounded.

Dr. Lenno Alab, a researcher at the University of California, Los Angeles, and his research team conducted a questionnaire survey and observational study on 34,000 test participants aged 18 to 85. The results showed that compared with people who did not eat nuts, participants who regularly ate walnuts had a significant lower chance of developing t2dm.

Although walnuts have high fat content, they are still suitable for diabetics to consume in small amounts every day.

3. Are walnuts suitable for people with constipation?

Nuts are good for intestinal health, which is related to their rich oil and dietary fiber characteristics, which are beneficial to intestinal movement; on the other hand, they are related to various nutrients rich in nuts, such as polyphenols and plant sterols.  They are all beneficial to adjust the intestinal flora. Among all kinds of nuts, walnuts polyphenols content ranks first, especially rich in total phenols, phenolic acids and sterols, with stronger antioxidant effect. Therefore, constipation is suitable for eating walnuts.
