In the last few years there has been much talk about resveratrol, due to the fact that this substance seems to have a very strong antioxidant, antimicrobial and anticancer action.
Just take a look at a few health benefits of resveratrol:
- Resveratrol may be highly beneficial for the teeth, because it prevent the adhesion of harmful bacteria in them and prevents tooth decay. The findings of Italian researchers show that drinking a glass of red wine a day can help maintain dental health and reduce the need for fillings. What is more, last year, a team of American researchers also discovered that certain chemicals found in large quantities in the seeds and skins of grapes prevent the adhesion of corrosive bacteria in dental enamel. The most dangerous of these bacteria called streptococcus mutans, live in the oral cavity and feed off sugars that come from our diet. These bacteria stick to the enamel, and trigger a process, in which acids (sugars have been metabolized by acid bacteria) begin to open holes in the teeth. In a recent study, researchers from the University of Pavia in Italy exposed the bacteria to a small amount of red wine (after extracting the alcohol), so to be sure what component of red wine is actually effective. The results showed that after exposure to resveratrol, the bacteria were no longer able to adhere to the teeth or the mouth.
- It may protect against diabetes: According to a study, resveratrol activates sirtuins, a group of proteins that is involved in many of the beneficial effects of calorie restriction. To verify this hypothesis, the researchers evaluated the metabolic effects of resveratrol administration directly into the brain of diabetic mice and found that it leads to improved levels of blood sugar and insulin. This effect is now being studied in humans and could pave the way for the development of new oral anti-diabetic drugs.
- It seems to act against inflammation: Scientists in Scotland and Singapore have found that resveratrol can control inflammation. The researchers provided an inflammatory agent in two groups of mice, one of whom had previously received resveratrol and the other not. The mice that had not previously received the substance showed a strong inflammatory response, while the mice that had received it did not develop inflammation.
- It can help you lose weight: It can activate the SiRT1 gene, which can help your body break down stored fat and increase your energy levels.
- It can slow down aging: Due to the activation of SIRT1 gene, this substance may help you remain young for longer. Some of the duties of SiRT1 is to repair DNA and protect the cells against free radicals, germs, toxins, UV radiation and inflammation. One of the causes of aging is that the SIRT1 is not working properly.
