According to Dr. Tapan Mehta of the University of Colorado Anschutz Medical Campus, among people with healthy kidneys, those who drank a little red wine daily (less than a glass) had a 37% lower risk of developing chronic kidney disease compared to non-drinkers. Among patients with chronic kidney disease, those who drank a little red wine daily (less than a glass) had a 29% lower risk of developing cardiovascular disease compared to non-drinkers.
Mehta and his colleagues analyzed data from the 2003-2006 National Health and Nutrition Examination Survey and data provided by the National Kidney Foundation, finding that moderate drinking is beneficial for both kidney and heart health. He analyzed that moderate alcohol consumption can lower urinary protein levels, and higher urinary protein levels may affect kidney function. As for the relationship between red wine and heart health, it may be due to the anti-inflammatory and antioxidant effects of polyphenols contained in red wine.
New research results from Harvard Medical School are also consistent with this study. It should be emphasized that moderate drinking is key, and there is no doubt that excessive drinking is harmful to the body. Do not drink too much, and it is best not to exceed two glasses per day.
