Taking vitamins after exercise may offset the benefits of exercise. German medical scientists have discovered that the body produces free radicals after exercise, and an appropriate amount of free radicals can help fight and prevent diseases such as diabetes. Supplements such as vitamins C and E have antioxidant effects and can inhibit free radicals. If you take vitamin C and E supplements after exercise, the effect of exercise will be greatly reduced, especially type 2 diabetes patients.
Some vitamins are antioxidants. Many people believe that antioxidant vitamins can reduce free radicals in the body. Taking antioxidant vitamins can protect body tissues from "oxidative stress", and free radicals may cause some diseases, such as cancer, heart disease, etc. , or cause aging. However, according to recent research from the University of Jena in Germany, taking too many antioxidants may do more harm than good.
The research team of Dr. Mike Restow of the University of Jena found that free radicals can have positive benefits for the body. Free radicals can increase insulin sensitivity. The insulin sensitivity of patients with type 2 diabetes is relatively weak, but antioxidant vitamins can counteract it. The benefits of eliminating free radicals.
Research results show that after men take vitamins C and E, there is no immediate change in the number of free radicals in the body. On the other hand, people who did not take antioxidants had higher free radical oxidative stress. The subjects underwent intensive exercise training for four weeks. Researchers found that the insulin sensitivity of the group that did not take antioxidants quickly returned to normal. The metabolic status of the group taking antioxidant vitamins worsened.
Sarah Aldred, a lecturer in sports science at the University of Birmingham in the UK, pointed out that this does not mean that vitamins C and E are harmful to the human body. The key lies in the timing of taking them. Elisabeth Weichselbaum, an expert from the British Nutrition Foundation, said that antioxidants can indeed protect body cells and help reduce the risk of cancer.
