Why to eat grapes twice a day to prevent old age? Stick to it for 6 months to get results!

In the past, it has been found that grape can prevent thrombosis, reduce serum cholesterol level, prevent cardiovascular and cerebrovascular diseases to a certain extent, and it can also help to eliminate free radicals in the body and delay aging. Recently, a new study published in the American Journal of experimental gerontology has added another great advantage to grapes: reducing the risk of Alzheimer's disease.

In the new study, Dr. Daniel h. Silverman, a researcher at the University of California, Los Angeles, randomly divided participants who showed early signs of memory decline into two groups: one group took whole grape beverage powder (equivalent to 340 grams of fresh grapes) every day, and the other group took placebo powder without polyphenols. The appearance and taste of the two beverage powders are basically the same. At the beginning of the study and 6 months later, the participants received cognitive test and brain PET scan to evaluate the changes of brain metabolism, which is of great reference value for clinical diagnosis of Alzheimer's disease. The results showed that grape rich diet could significantly inhibit the decline of brain metabolism and improve the cognitive and working memory ability of brain.

According to Dr. Silverman's analysis, grapes are rich in polyphenols, which can reduce the oxidation reaction in the brain, promote blood circulation in the brain, help maintain the level of key chemicals in the brain, enhance memory and reduce inflammation. This study further proves that eating grapes can improve nervous system and cardiovascular health. It is recommended to eat grapes twice a day for at least 6 months. A kind of
