It is believed that a glass of red wine or a shot of brandy good for the heart. Is it really? Indeed, many studies have shown that moderate alcohol consumption, ie 20 ml for men and 10 ml for women in terms of pure alcohol per day reduces the risk of cardiovascular diseases. It is this number protects against coronary heart disease and stroke.
10 ml of alcohol (96%) - about 250 ml of beer (5%), 100 ml of wine (12%) and 30 ml of vodka (40%).
When the alcohol helps?
The potential benefits from the use of alcohol is not. The small amount of red wine is good for the heart. To a small extent it helps to beer or vodka. The beneficial effects of other alcoholic beverages other than wine, is explained only by the fact that they increase the concentration of so-called "good" cholesterol (HDL).
Why just the wine?
This is due to content in it polyphenol called resveratrol. There is a substance in the skin of grapes. Resveratrol prevents vasoconstriction and enhances the arterial endothelium. Violation of these functions leads to atherosclerosis. Furthermore, prevents platelet aggregation and reduces blood thickeners secretion, increases "Good" cholesterol, but it is also a powerful antioxidant that protects the body against free radicals.
That's why so much talk about the "French paradox": the French eat saturated fat and less than residents of other countries suffer from diseases of the cardiovascular system. That's because they drink red wine.
The content of resveratrol in red greater than in white wine, which is the result of the production process.
It is useful to drink for health?
The relationship between heart disease and alcohol is of the form «U» capitalized: originally the incidence of falls, but the more we drink, the faster growing. At the same time, quite a lot of reasons not to consume alcoholic beverages.
According to WHO, alcohol ranks third among health risk factors:
● it is toxic to the liver,
● increases the risk of breast cancer and pancreas, oral cavity, larynx and esophagus,
● takes calcium from the bones - causes osteoporosis and gout,
● damages the nervous system,
● leads to a deficiency of vitamins and minerals, contributing to various diseases.
Do the recommended dose is safe?
Not really. It is designed for the average consumer and depends on many factors: gender, weight, age, metabolism, and overall health. In addition, regular consumption of even small amounts can lead to addiction.
Therefore, doctors do not recommend to drink alcohol as a preventative for heart disease. There are safer ways, such as healthy eating, physical activity, weight loss.
Important to remember!
Resveratrol is not present in all varieties of red wine. Most of the polyphenols contained in the grapes with thick skinned, ripening only in warm climates. In addition, important manufacturing process - the longer it is, the more resveratrol. This is a useful compound can be found in many fruits and berries: blueberries, cranberries, blackcurrant, mulberry, strawberry, raspberry and apples, as well as in nuts, tomatoes, and even chocolate. And instead of wine you can drink grape juice.
