The efficacy of grape seeds was discovered through a story of “waste recycling”.
A wine-making farmer was not willing to spend a large sum of money dealing with so much grape seed waste, so he thought of studying it. Maybe he would discover its special value. This research has made grape seeds a hot topic in the health food industry.
Because he discovered the highly bioactive antioxidant “proanthocyanidins” in grape seeds.
Anthocyanins and proanthocyanidins
When it comes to proanthocyanidins, it is necessary to mention anthocyanins.
◆Anthocyanin is a kind of bioflavonoid substance, a kind of water-soluble natural pigment, which is widely present in angiosperms, among which it is more abundant in berries such as black goji berries, blueberries and mulberries.
◆Proanthocyanidins are a type of polyphenol that is associated with a well-known compound, resveratrol, which is usually found in grape skins and seeds.
Although they differ by only one character, they are completely different substances.
The main function of proanthocyanidins is to act as antioxidants
Antioxidation mainly refers to the inhibition of oxidation reactions within the body. Oxidation reactions generate free radicals, which can initiate a response that causes cell damage and apoptosis, thereby leading to aging.
Antioxidants can neutralize free radicals in our bodies, prevent cell damage and apoptosis, and thus play a role in delaying aging.
Since the proanthocyanidins extracted from grape seeds have antioxidant effects, then why can’t we eat grape seeds directly?
According to the research results, the content of proanthocyanidins in grape seeds is approximately 3.18mg per 100g. As a general antioxidant, it is recommended that the daily intake of proanthocyanidins be 50mg.
Converted, each person needs to consume 1,572g of grape seeds every day to truly achieve the antioxidant effect. More than three pounds of grape seeds, I believe it’s hard for anyone to eat them…
Therefore, if you want to supplement proanthocyanidins, it is more efficient to directly take health supplements related to grape seeds.
Grape seed extract
Beneficial to the health of the heart, skin and brain
◆Lower blood pressure
The antioxidants in grape seed extract (including flavonoids, linoleic acid and phenolic proanthocyanidins) help prevent vascular damage and hypertension.
Studies show that grape seed extract can help dilate blood vessels and can assist patients with metabolic syndrome in lowering blood pressure.
◆Improve chronic venous insufficiency
Grape seed extract helps strengthen capillaries, arteries and veins, and improve blood circulation.
Eighty percent of patients with chronic venous insufficiency reported that their various symptoms had improved after taking proanthocyanidins for ten days, with a significant reduction in dullness, itching and pain.
◆Strengthen bones
Grape seed extract can enhance joint flexibility, promote bone formation, increase bone strength, and reduce the risk of osteoporosis, fractures and other diseases.
◆Improve swelling
The University of Maryland Medical Center pointed out that patients who took 600 milligrams of grape seed extract daily after surgery and persisted for six months experienced reduced pain and edema symptoms compared to those who took a placebo.
Another study shows that grape seed extract can effectively prevent leg swelling caused by prolonged sitting.
◆Improve complications of diabetes
Compared with individual intervention management, the combination of grape seed extract and exercise training is more effective in improving blood lipids, reducing weight, lowering blood pressure and alleviating other diabetic complications.
Researchers say, “Grape seed extract and exercise training are convenient and inexpensive ways to treat complications of diabetes.”
◆ Improve cognitive decline
Animal studies have shown that grape seed extract can reduce oxidative stress and protect mitochondrial function, thereby reversing hippocampal dysfunction in the brain.
Grape seed extract can even be used as a preventive or therapeutic agent for Alzheimer’s disease.
