Is Red Wine Good or Bad to Heart

It seems that you always hear about people talking about “red wine is good to health”. Is it right or wrong of this conclusion? Red wine and the resveratrol in red wine may be beneficial to hearth health. Then, what about the alcohol? Is it beneficial too?


People have been thought of drinking red wine is beneficial to heart health. The alcohol and antioxidant in red wine can prevent the occurrence of heart disease through increasing “beneficial” cholesterol and resisting artery injury. If you only have a glass of red wine in dinner every day, it is good to hear about above comment.
But, doctors always would not encourage people having wine since too much alcohol will bring a lot of side effect to human body.
Of course, many doctors agree that some substances in red wine really are good to heart health. This may be the effort of antioxidant, such as flavonoid, or a kind of substance called resveratrol that is helpful to heart health.

How does red wine affect heart health?

In comparison with other wine, red wine seems to have more characteristics that are beneficial to heart. But, it also may be no beneficial at all in comparison with beer, white wine and liquor.
At present, there is no certain evidence that red wine has much better benefits to heart than other forms of alcohol.
The antioxidant in red wine—polyphenol maybe can help protect the inner wall of heart blood vessels. A kind of polyphenols called resveratrol is one of the important substances in red wine that catches attention.
If you want the resveratrol in red wine to perform, you have to drink 60 liters red wine everyday.
Resveratrol may be the key substance in red wine to protect the blood vessels from damaging, reduce “harmful” cholesterol content and prevent thrombus.
Many researches about resveratrol are conducted on animals, but not human being.
According to experiment done on rats with resveratrol, this kind of antioxidant also can defend obesity and diabetes which are two risky factors for heart diseases. However, those founding were only on rats, but not human being.
In addition, in order to obtain the same amount of resveratrol, you have to drink 60 liters wine every day.
Some researches show that resveratrol is closely related to the two factors that induce heart disease. It also can reduce the risk of having inflammation and blood clotting. But whether it is the resveratrol that makes it work still needs further study.

The resveratrol in grape, replenisers and other food

The resveratrol in red wine comes from the grape peel that is used to brew red wine. It is because the ferment time with peel of red wine is much longer that that of white wine and so red wine contains more resveratrol.
Someone said that having grape or grape juice is a way to absorb resveratrol without having alcohol. Red and purple grape juice has the same beneficial as red wine.
Other substance with resveratrol includes peanut, blue berry and cranberry.
As for protecting heart, there is no evidence that having grape or other food is better or worse than having red wine. The resveratrol in food and red wine is changing all the time.
The resveratrol replenisers also can be used.
Although the researcher still does not fid any harm of having resveratrol, most resveratrol in replenisers cannot be absorbed.

How does alcohol protect heart?

All kinds of researches show that moderate drinking all kinds of wine is good to heart, not only red wine, people think alcohol can:
Enhance “beneficial” cholesterol—the composition of HDL.
Lower down the possibility of forming thrombus.
Help prevent artery injury caused by the increase of “harmful” cholesterol LDL.
Moderate drinking—or do not drink

Whether the red wine is good to heart or not still needs to be studied.

Those people who are suitable to drink, including red wine, seems to have lower risk of having heart disease. However, we still need more evidence to prove that red wine is more beneficial than other wines, such as beer or liquor, to heart.
No matter the American Heart Association or the National Institute of Heart, Lung and Blood all advocate having less alcohol to prevent heart disease.
Alcohol also can make people addictive or cause other serious health problems. Excessive alcohol will increase the risk of having hypertension, high glycerate, liver damage, obesity, and some kinds of cancer, accident or other problems. In addition, drinking often will also cause cardiomyopathy—weaken cardiac ability—the symptoms of cardiac failure. If you have cardiac failure, or weak heart ability, then you should not have alcohol at all.
If you have aspirin everyday, then you should avoid drinking or drinking moderately according to the suggestion of doctors. If you are pregnant, then you definitely cannot drink. If you still have doubts about alcohol, you should consult the doctor.
If you have already had red wine, then have it moderately. Moderate drinking means make have two shares and female one share every day.
The reason why male can have more is because the average weight is bigger than that of female and male has more enzymes to metabolic alcohol.
A share refers to 12 ounce (355 ml) beer, 5 ounce (148 ml) grape wine or 1.5 ounce (44 ml) 80% distilled water.
