Usually spit out the grape seeds, but some businesses hype it as anti-cancer, anti-oxidation, anti-aging All kinds of "grape seed oil" and "grape seed powder" on the market are selling very well Are grape seeds really so effective? Experts say that the magic effect of grape seed health care is that businesses are stealing concepts Can grape seed fight cancer? The reporter looked up a lot of data and found that the experimental data of grape seed extract inhibiting cancer cells are quite a lot, but the premise of conclusion is very clear: "in vitro experiment can inhibit cancer cells" Professor Li duo, Department of food science and nutrition, Zhejiang University, explained that "in vitro experiment can inhibit" and "in vivo can inhibit" are totally different things "In vitro experiment" can only show that further research can be carried out for specific cancer cells, and there is no evidence that grape seed extract can inhibit cancer cells in vivo Yun inadvertently pointed out that British scholars published a phase II clinical study of grape seed extract assisting cancer patients The volunteers who had breast cancer radiotherapy in the early years were divided into two groups, one group took grape seed and the other group took placebo The results showed that there was no difference between the two groups In addition to anti-cancer, promoting the antioxidant function of grape seeds is also the concept of many businesses Experts say grape seeds do contain proanthocyanidins, an antioxidant, but it remains to be seen how effective the ingredient can be Chen Wei, a physician in the Department of parenteral and enteral nutrition of Peking Union Medical College Hospital, explained that antioxidation is actually to eliminate the cell damage caused by oxidation, which is also the basis for the relationship between antioxidation, anti-aging and disease prevention Grape seed health care products said "antioxidant" is only based on this theory, there is no clinical data for the actual situation, so all kinds of beauty, anti-aging and other functions are "good wishes" Yang Wenjiao, a national second-class public nutritionist, said that compared with the antioxidant ingredients in other fruits and vegetables, grape seeds do not have much in particular, and there is no need to rely exclusively on grape seeds to supplement Yun inadvertently pointed out that the components of grape seed extract are relatively complex and have not undergone systematic and sufficient safety research Considering that such research is not sufficient, pregnant women and children should not take it.
