There are some studies where we read the headlines and believe, because we like the headlines and want to believe in it!
I saw one article the other day that said “A new study says a glass of red wine is the equivalent to an hour at the gym”. I was thrilled, no gym! Not that I drink a glass of wine everyday, but nor do I go to the gym everyday. But, when I do drink a glass of wine, I could make myself feel good.
I went to the source to find out more. The article, ‘Improvements in skeletal muscle strength and cardiac function induced by resveratrol during exercise training contribute to enhanced exercise performance in rats’ was published in the Journal of Physiology. The key points in the article were that resveratrol, which is found in the skin of grapes and therefore red wine has benefits for the cardiovascular systems. The exercise training in rats that were fed resveratrol improved their exercise performance and energy metabolism. The endurance capacity was increased in rats whose diet included resveratrol during a 12-week endurance-training program.
Nowhere in the article does it say “A glass of red wine is the equivalent to an hour at the gym’. Sorry folks, just red wine and no excercise will not help. But maybe a glass of red wine while excercising might help your endurance!!! J However the results showed that it increased the endurance only by 1.2 -1.5 times for rats. So, don’t get your hopes up high!
By the way, even that one glass is a fallacy – if we need to take the same milligrams per kilogram of weight of resvertrol that needs to give you a benefit you will have to drink three liters of red wine. So, you will have a good heart, but a bad liver!
