Recently I heard on a radio science show something very interesting regarding antioxidants. Apparently they negate the training effect of exercise. One of the usual goals of exercise is to become healthy, stronger and more capable. We do this by over loading the muscles, causing slight damage and then when they repair they come back stronger. In damaging the muscles we cause oxidative stress. As it turns out the, we need these free radicals to stimulate the body’s own antioxidants and cause the wonderful training effect of exercise. If you train and take antioxidants supplement you won’t get this effect and you won’t change physically. If you want to get buff, throw away the pills and get some tasty, good whole foods.
