Grape seed: natural antioxidant

Grape seed is the leftover of winery It is the product of separating grape skin and grape stem after drying Grape seeds contain flavonoids and resveratrol, which are natural products with strong antioxidant and anticancer effects In recent years, the research of flavonoids with antioxidant effect has been a hot topic in food and medicine At present, there are more than 500 kinds of known biological flavonoids Compared with most flavonoids, the biological flavonoids extracted from grape seeds have special structure, good water solubility, high efficiency, and more than 90% bioavailability, which are easily absorbed by human body Flavonoids extracted from grape seeds can dilate blood vessels, increase peripheral blood circulation and blood flow speed, reduce cholesterol content in blood, improve the proportion of cholesterol and phospholipid, effectively inhibit thrombosis, improve symptoms of coronary heart disease, hypertension and cardiovascular and cerebrovascular diseases, promote cerebral circulation metabolism, improve memory function and brain damage Both the recovery of injury and Alzheimer's disease have active therapeutic and health care effects; it has the functions of anti-bacterial and anti-inflammatory, inhibiting cancer promoter (TPA), improving human immune function and anti-aging function The OPC (proanthocyanidins) rich in grape seeds has very strong anti-oxidation ability, which can even be said to be the most powerful pure natural antioxidant found so far It can effectively remove the excess free radicals in the body, protect VC and ve from being oxidized and inactivated before reaching the effective site, and make them play a strong anti-oxidation role together Therefore, it is called the synergist of VC and VE OPC is a water-soluble substance, which is easy to combine with collagen, hard elastic protein and connective tissue It is easy to be absorbed by the human body and transported to all parts of the body The "survival" period of the human body is long After oral administration for 7 hours, half of the original dose still remains in the body to play a role At present, the research and test of using grape seeds to develop health products have achieved remarkable results It is hoped that health food with grape seeds as raw materials will enter thousands of households as soon as possible.
