The wine has been proved to have a beneficial effect on the heart. This beneficial effect of red wine on the heart has been attributed to its richness in Phenolic flavonoids, substances that are found in grapes and its skin. The phenolic flavonoids give red wine its characteristic color, they act to stop the oxidation of lipoproteins, and in-turn preventing arteriosclerosis (deposition of cholesterol within the arteries).
According to various studies conducted statistically, the consumption of 1/2-1 cup of red wine a day lowers the risk of death from heart attack. The studies showed that this beneficial effect seems to involve more of men over the age of 50. From the same statistical research conducted, when more than 1 cup of wine is consumed a day, the death rate due to cardiovascular disease increases, and many other disorders are promoted as well.
We have seen above how the consumption of too much wine can be harmful to our health, and how the consumption of a regulated amount can be beneficial to our health. Therefore, since wine is from grapes, whatever benefit coming from wine is still from grapes. Thus, to be on a safer side, the consumption of grapes themselves or its juice is much more healthier for the heart and the entire body than consuming wine.
