However, a recent study seems to really make this tongue twister "come true". Grape skins and grape seeds, which seem to be thrown out casually when eating grapes, actually have very objective health values.
The study was published in the journal Natural Metabolism, and the experimental results were jointly developed by researchers from relevant nutrition institutions in China and the United States. Analysis of chemical substances in grape seeds and skins.
According to the researchers' extraction research, the results show that grape skins and grape seeds contain a very wonderful proanthocyanidins extract named pcc 1, which is not found in other common fruits.
Subsequently, the researchers used the extracted pcc 1 to carry out experiments on mice. They injected pcc 1 with fluorescent label directly into old mice by intraperitoneal injection, and then observed their physical changes.
The results showed that the fluorescent markers in aging mice gradually decreased, and they interacted with aging cells, which truly showed the correlation between pcc 1 and aging cells. Subsequently, the researchers dyed fluorescent labels on aging cells and reinjected them into mice, and the same results were obtained, which further proved the anti-aging effect of pcc 1 in animals.
In other words, proanthocyanidins extracted from grape skins and grape seeds (pcc 1) can indeed inhibit cell oxidation, thus helping animals to delay aging and promote longevity. It is indeed a new research achievement worthy of the happiness of elderly friends.
Not only that, this proanthocyanidins can also make achievements in the direction of anti-oxidation and anti-aging. According to the researchers' further research, pcc 1 is also quite good for cancer and anti-cancer.
According to the contents of the paper published in Natural Metabolism, we found that the researchers used pcc 1 in the following experiments.
The specific process is as follows: human prostate cancer cells and human aging cells are mixed according to the experimental proportion, and after the same injection of fluorescent labeling, pcc 1 is used in combination with some chemotherapy drugs, and is also injected into the culture medium of prostate cancer cells for at least 8 weeks.
The results showed that the tumor cell volume was reduced by about 55% compared with chemotherapy alone, and the tumor volume was reduced by 75% compared with the culture medium without any drug treatment.
Not only can it resist aging, but it can also fight cancer. This "pcc 1" extracted from unremarkable grape skins and grape seeds will definitely have unimaginable research value in the diagnosis and treatment of senile diseases and cancer in the future, which is worth looking forward to.
However, when you are happy, many friends will think about eating grape skins and grape seeds on purpose after hearing about such research results, in order to live longer.
We can understand this feeling, but this approach is biased.
Practically speaking, it is not feasible.
What we need to understand is that proanthocyanidins extracted from grape skins and grape seeds can really resist cancer and aging, and they must be further purified to get a reasonable concentration before they can really play their role.
The skins and seeds produced by eating grapes at ordinary times obviously can't meet this requirement. If you eat a lot of grape seeds, you may be poisoned by excessive anthocyanins and other toxic substances in the seeds, thus damaging your health. Therefore, please be careful not to eat blindly.
Regarding grape skins, "eating grapes without spitting grape skins" is reasonable, and there will be no hidden danger of poisoning if you eat them properly. In addition, grape skins are rich in protein and vitamins. It is strongly recommended that everyone eat grapes together, but for the sake of health and hygiene, please be sure to wash them before eating.
