Red Wine bad for Older Men
You will soon need to remove red wine from your after retirement plans as a new study reveals that red wine could be bad for older men. A natural antioxidant compound found in red grapes and other plants called resveratrol blocks many cardiovascular benefits of exercise in older men.
Though previously resveratrol has had received widespread attention as a possible anti aging compound and is available as dietary supplement, now researchers are saying otherwise. Researchers from the University of Copenhagen now suggests that eating a diet rich in antioxidants may in fact counteract many of the health benefits of exercise, including reduced blood pressure and cholesterol.
Lasse Gliemann, a PhD student who worked on the study said that they studied 27 healthy, physically inactive men around 65 years old for 8 weeks. He said that during the 8 weeks all of the men performed high-intensity exercise training and half of the group received 250 mg of resveratrol daily, whereas the other group received a placebo pill.
Gliemann further mentioned that while exercise training was highly effective in improving cardiovascular health parameters, resveratrol supplementation attenuated the positive effects of training. This happened on many parameters including blood pressure, plasma lipid concentrations and maximal oxygen uptake.
