American scientists told about the unexpected properties of dark grapes. It turned out that regular consumption of resveratrol, a substance released from the skins of this berry, has a positive effect on bone tissue, reducing the risk of osteoporosis in obese people.
Observation of a group of men and women was conducted for 16 weeks. As a result, it was found that regular intake of resveratrol led to the rapid growth and renewal of cartilage tissue, the bones became more dense.
It should be noted that this effect can be achieved only in the case of receiving significant doses of this substance. However, according to doctors, in order to prevent, you can take small doses of resveratrol contained in dark grapes, as well as drinks from it.
Curiously, red wine is not the best source of resveratrol. A great alternative to it is grape sauces and juices (without sugar).
