Antioxidants Not Behind Red Wine's Healthy Effect on Heart: Study

FRIDAY, Sept. 23 (HealthDay News) -- Many studies have shown that a glass or two of red booze a day is heart-healthy, and most of a benefit has been attributed to a anti-hypertensive effects of antioxidants found in red booze called polyphenols.But a new Dutch study suggests that these polyphenols, at least in isolation, may not lower blood vigour after all.Study author Ilse Botden, a graduate student at University Medical Center in Rotterdam, pronounced a new findings "do not support" a lowering of blood vigour by polyphenols as a source of red wine's benefits to a cardiovascular system.The findings have been slated to be presented Friday at a American Heart Association's High Blood Pressure Research meeting in Orlando, Fla. The new research involved 61 people averaging about 61 years of age, all of whom had borderline high blood pressure. Participants were given dairy beverages that contained either a red booze polyphenols or a harmless placebo.Botden's team found no difference in blood vigour levels in between a two groups after four weeks on a regimen. "Red booze drinking may still be beneficial to prevent cardiovascular diseases. However, this assumingly occurs in a blood pressure-independent manner," Botden said.Dr. William O'Neill, a professor of cardiology and a executive dean for clinical affairs at a University of Miami Miller School of Medicine, agreed that a findings do not mean that red wine, in moderation, isn't heart-healthy."We know that moderate consumption of red booze helps decrease a person's risk for heart disease and heart attack," pronounced O'Neill, who was not involved in a study.Instead, this research seems to contend that booze does not decrease heart risk through a mechanism of lowering blood pressure. Instead, red booze may have anti-inflammatory properties that lower cardiovascular risk, he said. Another theory is that something in red booze help decreases a "stickiness" of blood and decreases a risk of a blood clot that could cause a heart attack, O'Neill said. "We alway! s want t o get out a magic potion, and put it in tablet form, but this study shows us that it's more complicated," he said.Dr. Suzanne Steinbaum is a preventive cardiologist at Lenox Hill Hospital in New York City. She noted that a people in a study had borderline high blood pressure, and a results may not apply to people with higher blood vigour levels. The study also only lasted a month, she said, and a benefits from polyphenols might take longer to accrue."There have been multiple components in red booze and taken together, these ingredients have been shown to decrease blood vigour and prevent clotting and heart attacks," Steinbaum said. Moderate consumption of red booze is also part of a Mediterranean diet or lifestyle, which is rich in fruits, vegetables, whole grains and lean proteins. "This lifestyle is good for heart health," she said.Research presented at medical meetings should be deliberate preliminary until published in a peer-reviewed medical journal.
