Study: Wine Only Beneficial Against Cardiovascular Disease For People Who Exercise

shutterstock_3284818Many people may have heard about the health benefits of drinking red or white wine. Its benefits include helping protect against cardiovascular disease if consumed in moderation. But according to the results of the In Vino Veritas, or IVV, study, the health benefits of wine may only be functioning in people who exercise. The results were recently presented at the European Society of Cardiology (ESC) Congress.

The IVV study was the first long-term, randomized trial comparing the effects of red and white wine on known markers of atherosclerosis among people with mild to moderate risk of cardiovascular disease. The said study involved 146 people with mild to moderate risk of CVD. The participants were then randomized to a year of moderate consumption of red wine or white wine, all from the same year and the same wine region in the Czech Republic. Moderate consumption, according to the WHO, is 0.3L for men and 0.2L for women for a maximum of five times per week.

One of the primary targets in the said study was to determine the HDL cholesterol level in one year. Other targets include levels or other markers related to atherosclerosis including LDL cholesterol. The participants of the said study still followed their usual diet.

As part of the study, the participants were also instructed to keep a logbook of their wine consumption and other alcoholic beverages, any intake of medicine as well as the type and amount of exercise they follow.

The researchers discovered that there was no substantial difference between HDL levels at the beginning and the culmination of the said study in either of the red wine and white wine groups. On the other hand, LDL cholesterol was lower in both groups after a year. Total cholesterol levels were only lower among the red wine group.

According to Professor Milos Taborsky, one of the authors of the said study, “A rise in HDL cholesterol is the main indication of a protective effect against CVD, therefore we can conclude that neither red or white wine had any impact on study participants as a whole.”

“The only positive and continuous result was in the subgroup of patients who took more exercise, which means regular exercise at least twice a week, plus the wine consumption. In this group, HDL cholesterol increased and LDL and total cholesterol decreased in the red and white wine groups. There may be some synergy between the low dose of ethyl alcohol in wine and exercise which is protective against CVD,” Professor Taborsky further added.

“Our current study shows that the combination of moderate wine drinking plus regular exercise improves markers of atherosclerosis, suggesting that this combination is protective against cardiovascular disease,” he concluded.

Studies in the future may include studying the effects of red or white wine among people who may be at high risk of CVD and how taking medications such as statins and regular exercise may have an effect on the markers of atherosclerosis.
