Red wine study - According to a study by King's College London, red wine would diversify the bacteria developed by the intestine and ensure a better defense of the immune system and therefore a better state of health. According to some scientists moderate consumption can have beneficial effects on the body. For example, an American study suggested in 2018 that drinking a small glass of wine a day helped to increase life expectancy. Scientists have denied these results by opposing the fact that regular consumption of alcohol increases the risk of cancer. A recent study, British this time, established that drinking red wine, and only red wine, would diversify the gut bacteria that helps strengthen the immune system and improves an individual’s general health status.
