There are many opposing studies about the benefits of red wine. Some point to the benefits of red wine; others find it may be harmful.
The key is moderation, when it comes to drinking wine or any other type of alcohol. If you’re looking for health benefits, limit your red wine consumption to a glass or two a day.
There’s no doubt that drinking wine or any alcoholic beverage – in excess can affect your health, career, and relationships, there’s some evidence that moderate consumption of wine may have significant health benefits. There are health professionals try to warn against the dangers of alcohol consumption, making it hard to understand the real story about wine, your health, and longevity. There are both positive and negative studies on how red wine consumption can affect people.
Red wine it is reach with antioxidants, also known as polyphenols. They are thought to protect your body’s cells and tissues against damage that can lead to the development of diseases such as cancer and heart disease.
The polyphenols in wine primarily come from the colored skins of grapes. That means that red wine tends to have a higher concentration of polyphenols than white wine, according to Georges Halpern, MD, PhD, a professor of pharmaceutical sciences at Hong Kong Polytechnic. “It seems that these substances in higher concentration have a better protective effect on the cardiovascular system and possibly other systems,” Dr. Halpern says.
Protect you from developing a heart disease
Over the past 20 years or so, many journals have published studies about how drinking alcohol, particularly red wine, may protect the heart, according to the American Heart Association. So when researchers challenged that notion in a 2014 study published in JAMA Internal Medicine, they raised some eyebrows.
Drinking a glass of wine per day could help keep the blues away, according to PREDIMED study on Mediterranean diets.
Why? A healthy heart means a healthy mind, and wine’s benefits for the heart keep the blues away for moderate wine drinkers.
The researchers studied Italians who consumed large amounts of the polyphenol resveratrol and found it did not protect them from developing heart disease or cancer.
Protecting against certain cancers
A study published in Advances in Experimental Medicine and Biology in 2014 found that resveratrol may prevent head and neck cancer. The resveratrol kills damaged cells that can lead to cancer, slows their growth by cannibalizing themselves. Another study, published in 2014 in the Royal Society of Chemistry’s Food & Function, found that the more polyphenols, particularly resveratrol, in wine, the more the wine protects against colon cancer.
Slowing memory loss
Researchers at the Texas A&M Health Science Center College of Medicine found that resveratrol may help prevent age-related memory decline. They published the findings from their study of rats in “Scientific Reports” in January 2015.
Help you with weight loss
Researchers in Korea found that the compound piceatannol, which is found in red grapes and is similar to resveratrol, can block cellular processes that allow fat cells to develop and grow. Piceatannol could be used as a weapon against weight gain, the researchers wrote in their study, which was published in The Journal of Biological Chemistry in 2012.
Reservatrol which is part of both berries and red wine, turns bad, obesity-inducing white fat into good calorie-burning beige fat that the body uses for energy.
In a recent study by Washington State University polyphenols, caused mice to burn excess fat through body heat.
Protects your teeth
A 2014 study published in the Journal of Agricultural and Food Chemistry found that red wine may kill dangerous bacteria in your mouth that could cause dental diseases, including cavities. An active component in the grapes has antimicrobial effects on bacteria in the mouth. And the best news it could lead to safer tastier mouthwash being developed.
Help fight off the common cold
There is a lot of evidence to suggest that moderate wine drinking, can boost your immune system, making you 40% less likely to suffer bouts of cold.
Why? The non-alcoholic components of red wine, particularly reservatrol, may suppress the immune response that leads to the cold manifesting itself.
Protects your sight
Though too much wine can cause double vision, drinking red wine may offer protection against loss of eyesight.
Why? Reservatrol appears to stop the abnormal growth of new blood vessels or angiogenesis in the eye. Angiogenesis typically leads to page-related loss of eyesight or even blinding disorders.
Other research results show that wine consumption is in an association with increased risk for certain cancers.
A study published in Alcohol and Alcoholism in 2012 found that drinking wine could increase a woman’s risk for breast cancer. According to Cancer Research UK, alcohol consumption also increases the chances of developing mouth, throat, liver, and bowel cancer in some people.
While research and the debate continue, the key seems to be moderation. Too much wine can damage your body, but one glass a day for women and two a day for men, might be the enough to enjoy alcohol’s health benefits.
If you prefer not to drink alcohol, the good news is that you can get the same health benefits from wine with significantly lower alcohol levels, Halpern says.
