The Study led by Dr. Tapan Mehta, a renal fellow at the University of Colorado Anschutz Medical Center, and his colleagues studied 4-year data from the National Health and Nutrition Examination survey from 2003-06 based on the wine consumption by 5852 participants, 1031 of whom already had CKD.
The researcher found that the subjects who drank up to one glass of wine a day had a 37 per cent lower prevalence of CKD than those who drank no wine at all. And those who already had CKD were 29 per cent less likely than teetotalers to have cardiovascular disease if they drank less than a glass a day. Dr. Mehta has presented preliminary findings at a meeting of the National Kidney Foundation.
The findings support the past studies suggesting that a single glass of red wine a day for women and up to two glasses for men help protect your heart, said Dr Leslie Spry, a spokesman for the Foundation.
Dr Joel Topf, a nephrologist in Detroit and president of the scientific advisory board of the Foundation endorses the result and says, "It doesn't surprise me that, as we learn that wine is protective to the heart, we're seeing the same effect on the kidneys." However, he cautions that more research needs to be done to clearly establish cause and effect. It's not clear, for example, whether those who were sickly or had kidney disease had avoided alcohol because of their health concerns or whether the avoidance led to health problems. He also notes that too much wine can push up blood pressure, a major cause of chronic kidney disease.
It may be the alcohol and antioxidants in red wine boost levels of high-density lipoprotein (HDL), the good cholesterol and protect against artery damage, according to the Mayo Clinic, reports NZHerald even as the study didn't differentiate between red and white wine. Dr. Mehta did observe that more people drink red wine than wine,
Dr. Mehta also warns against advising teetotalers to start drinking wine if they have kidney disease. “This is just an association study, so we can’t conclude any cause-and-effect relationship; so we can’t yet recommend people with kidney disease to start drinking wine,” he said.
According to the American Heart Association, one glass of wine is four ounces (125 mL or the equivalent of 6 glasses a bottle). Although it is not specific about the alcohol level, it is safe to assume that it refers to12.5% alcohol level and if the alcohol is higher-say 20% for the volume of 15%,the intake quantity ought to be reduced by 20%.
The Study seems to be yet another endorsement of the advisory by delWine of drinking daily one glass of red wine for women and up to two glasses of red wine, preferably with meals-editor |
