Resveratrol-rich food source

What is the resveratrol sources

Resveratrol is a polyphenolic compound and plants are its only food source. About 70 plants can produce this substance to protect against pathogen attacks such as fungi and bacteria. All of these plants have varying amounts of resveratrol.?

Data on the source of resveratrol dates back to 1940, when Japanese scientist Gao Gang isolated the compound from white gourd. Then, resveratrol was also found in Japanese cockroaches. But this compound really became known because of the puzzling data of the French about diet and health. The French people's diet has a large proportion of fat, but their cardiovascular disease incidence is very low, which has caused widespread concern among scientists. The study found that this is related to the French people's daily habits of consuming red wine. Red grapes are one of the rich sources of resveratrol.

Resveratrol from grapes is found mainly in the peel and grape seeds. However, white wine does not contain resveratrol because white wine does not use grape skin during processing. One liter of red wine contains approximately 0.2-5.5 mg of resveratrol. The difference in content is mainly related to grape varieties, soil environment, cultivation methods, varieties and pests. Red grape juice and Spanish rose wine are other sources of resveratrol, ranging from 0.06-1.30 mg (150 ml).

Studies have found that wines produced using the same grape source produce more resveratrol than juice. This may be related to the conversion of resveratrol to the substance called spruce.

In addition to grapes, peanuts also contain resveratrol. Studies have confirmed that the resveratrol content of cooked peanuts and red grapes is very similar. For example, a glass of red grapes can provide about 0.25-1.25 mg of resveratrol. A cup of cooked peanuts can also provide the same amount. Bilberry and blueberry contain 10% less resveratrol than grapes. After heating and cooking, the resveratrol content of cranberry and blueberry will be further reduced.

Currently, there are many studies investigating the benefits, side effects and appropriate doses of resveratrol. But before the new research results come out, it is best to consume in moderation. The recommended intake of resveratrol supplements in the form of enteric capsules is 15-20 mg per day.
