Fermentation is a process of converting carbohydrates into alcohol by yeast and under the influence of the environment with a limited amount of oxygen. Wine is what happens when the grape juice ferments. Red wine is formed when the grape skin is included in the process of fermentation.
White wine can be made from any kind of grapes. Recent studies have shown that drinking a glass of red wine a day is healthy. The moderate consumption of wine protects against cancer, heart disease, improve cholesterol levels and blood pressure.
The concept of moderate consumption in the US means one glass for women and two glasses for men. On the other hand in the UK and the EU as a moderate amount of perceived three cups for women and four cups for men.
Excessive alcohol consumption has no benefit to the body. Excessive alcohol consumption, including wine, causes liver cirrhosis and alcoholism. Glass or two are enough to reduce the risk of heart disease, cancer and stroke.
The French, as we well know, understand a little bit more of the secrets of red wine. In a study comparing French and German wines, the French showed better results because they contain a large amount of antioxidants.
This also applies to the “French Paradox.” Despite the high levels of fat in the traditional French cuisine, the French suffer far less from heart diseases than the Americans. The evidence is inconclusive, since there is a big difference in the eating habits of both sides.
Actually there are two main components in red wine that make it with healing properties – antioxidants and resveratrol.
Resveratrol is produced naturally by the skin of grapes during fermentation. Generally, white wine contains lower levels of resveratrol.
What we should know about resveratrol?
Resveratrol is one of the new hits on the market for health supplements in the recent years. It is claimed that resveratrol cures diabetes 2, prolongs life and even stops cancer.
Proven benefits of taking resveratrol:
The most important and proven effect of the resveratrol is its antioxidant effect. Thanks to him, he stops the action of various free radicals that can damage our cells. Studies have shown that resveratrol works with vitamin E and his fellow substances.
- Improvement in the treatment of diabetes 2 – currently actively experimenting with laboratory animals and humans.
- Athletic achievements. It is believed that resveratrol unlocks sports gene SIRT 1, which significantly improves the performance in terms of rate of metabolism, hormone levels, etc.;
- Extension of life (anti-aging);
- It is believed that the way in which resveratrol acts, as is unlocked and stimulate certain genes in human DNA and thus leads to an improvement in the overall metabolism.
Red wine is undoubtedly one of the richest sources of polyphenols in our diet. They are powerful antioxidants, which are obtained from the skin, seeds and even the stalk of the grapes. The polyphenols are generally formed during the fermentation of red wine.
The most powerful and famous among polyphenols is resveratrol. It reduces inflammation, lowers “bad” LDL cholesterol and prevents blood vessels. Also reduces the risk of diabetes and Alzheimer’s disease and may stop the growth of cancer cells (at least in the laboratory). But we must consider that in high concentrations resveratrol may be toxic. There are not enough researches on the effects of the antioxidants to the human health, so we do not know whether the amount in a glass of red wine is enough to take full advantage of the healthy abilities of resveratrol.
The health benefits of red wine
Moderate and regular consumption of red wine is beneficial not only because of the ingredients in this aromatic drink, but mostly because of the lifestyle that man leads along with the wine.
Many people know that red wine is beneficial to health because it contains polyphenols. But increasingly, experts believe that lifestyle and the way we drink are more important than what kind of alcohol you consume.
In 1992, Dr. Serge Renaud paid attention to the fact that people in France rarely suffer from heart disease compared with those in northern Europe, although there was no difference in the amount of saturated fat in the diet of both groups. He called this “French paradox” and devoted it to the Mediterranean diet and the red wine.
Later, several studies have shown that alcohol, regardless of its type, it may be beneficial to health when consumed in moderation. It raises “good” HDL cholesterol, has anti-inflammatory abilities and helps to control the level of glucose in the blood. The negative effects are that increases the risk of high blood pressure, kidney disease, etc. The end result is a J-shaped relationship between alcohol and mortality, where moderate consumption increases the chances of a long life, and excessive them lowered.
Maybe it’s important what is your lifestyle?
In general, researches show that people who drink wine, have a healthy lifestyle. Usually the wine drinkers eat more fruits and vegetables, move more, smoke less. So really, it is possible to have a good health by keeping the red wine in your lifestyle.
The rise in blood lipids and oxidative stress after eating is a well-known risk factor for developing atherosclerosis. However, this can be prevented with the help of polyphenols from the grapes. Because usually people who drink wine, drink a glass with dinner and this may be an important factor. According to the statistics, people who drink red wine in moderate amounts rarely begin to abuse with alcohol.
Red wine and prevention of cancer
Although there is not enough conclusive evidence, the laboratory tests and studies suggest that resveratrol contained in red wine, may help to suppress the growth and reproduction of cancer cells of the breast cancer, leukemia and skin cancer. The growth of other types of cancer cells such as prostate cancer and colon also have been shown to reduce by the consumption of moderate amounts of red wine.
Red wine and heart diseases
The results of the studies show the benefits of resveratrol in the prevention of cardiovascular disease and stroke. Researchers attributed mainly to the ability of resveratrol to thin the blood, which prevents blood clots in arteries and other blood vessels. Namely such combination produces a condition called ischemia, or lack of oxygen in the heart, which can cause a heart attack. Several studies conducted in France showed that resveratrol protects against potential future cases of heart failure.
Red wine, cholesterol and blood pressure
Red wine contains ingredient called saponin – another antioxidant. Recent studies have shown that red wine leads to a decrease in the level of LDL. Because of its ability to prevent the accumulation of “bad” LDL cholesterol, red wine is an effective alternative for lowering high blood pressure.
In addition to the above, may be added several health benefits of red wine. Resveratrol has similar properties to those of the female hormone estrogen – that is why red wine can be very useful in periods when the estrogen level decreases – during the menopause, by breast cancer, after birth, osteoporosis, etc. Catechins – other antioxidants contained in red wine protect the heart, and the antioxidant kuertsitin reduces the risk of lung cancer.
Although red wine already has earned a worldwide reputation as a useful health drink to take advantage of its beneficial actions, we should consume in moderation. Too much alcohol, particularly red wine and can lead to alcoholism, obesity, high blood pressure, damage to the liver and many other health problems.
What is clear and what is not?
It is not sufficiently proven that red wine is a more beneficial than beer or liquor. Yet the message might be, however, that it is more important how and how much we drink than what we drink.
If you do not drink, there is no reason to start, even if your goal is to prevent cardiovascular disease – alcohol is addictive and may worsen other aspects of your health. If you like to drink, there is no reason to stop doing it as long as it is a in moderation.
Glass of red wine is not only a temptation for the eyes and the mouth, but also contributes to our health. Consuming a glass or two of red wine is considered beneficial in the prevention of many diseases and to maintain overall health.
Red wine is a naturally rich in antioxidants, According to studies, has a good effect on the prevention of cardiovascular disease and certain cancers. It has been proven and that the wine has a positive effect on lowering blood pressure and cholesterol levels in the body. The main ingredient in red wine that has a role in prevention of disease is resveratrol – a specific antioxidant, which suggests that there are even anti-cancer characteristics.
