In fact, the magic of proanthocyanidins goes far beyond this. It can also promote skin blood circulation, promote skin cell metabolism and take away waste. As proanthocyanidins itself is a strong antioxidant, it can also repair the skin damage caused by sunlight and ultraviolet rays, maintain the vitality of skin cells, delay the generation of wrinkles and rejuvenate the face. Therefore, it is scientific to eat grapes and drink dry red wine for beauty. Later, a large number of studies showed that proanthocyanidins not only have the health care functions of antioxidation and promoting blood circulation, but also have various medicinal effects such as antibacterial, anticancer, anti-inflammatory and cataract prevention. Its health magic is really strong!
Finally, I will tell you a secret. Although the sweet pulp of grapes contains a certain amount of proanthocyanidins, the content of proanthocyanidins in grape skins and grape seeds is much higher than that in the pulp.
Of course, proanthocyanidins also exist in other plants besides grapes. For example, while people found that grape proanthocyanidins have protective effects on cardiovascular and cerebrovascular diseases, the French also found that pine bark has antiviral and antibacterial active ingredients, which are actually proanthocyanidins! As early as 300 BC, Europeans used the inner layer of pine bark as food to satisfy hunger, prevent wound infection and treat inflammation. Before the birth of the United States, a large number of seafarers and immigrants who went to America to explore the new world suffered from severe hunger and disease, and more than half of them died. The remaining few are exhausted and dying. Thanks to the help of the local native Indians, I learned how to use the local pine bark. Slowly, these people came alive, and then there were a lot of immigrants, and then there was America. In addition, apple, hawthorn, red vegetables, chocolate, medlar and citrus also contain proanthocyanidins, but the content, molecular composition and polymerization degree of proanthocyanidins are different.
