Rumor: Can Drinking Red Wine Prevent Cardiovascular Diseases?
Truth: It is not reliable to drink red wine to prevent cardiovascular diseases.
Some studies believe that resveratrol in red wine may have the effects of preventing vascular injury, reducing low density lipoprotein cholesterol and preventing blood coagulation.
However, most studies on resveratrol are based on animals, and whether resveratrol has the same effect in humans is still uncertain.
Experiments on rats show that resveratrol may prevent obesity and diabetes, both of which are high risk factors for heart diseases. However, if the amount of resveratrol consumed by rats in the experiment is to be equivalent, a person should drink 1,000 litres of red wine every day!
Recently, a study by Johns Hopkins University School of Medicine even suggested that resveratrol is not directly related to cardiovascular health. Therefore, drinking red wine to prevent heart disease is not reliable.
