The Science Behind Health Benefits of Red Wine

red wine health benefits

 

Red wine can slim risks of osteoporosis

Osteoporosis is an age-related bone thinning, which is related to calcium loss.

A study published in the American Journal of Epidemiology showed that women who drank one to three glasses of wine had greater bone mineral density. Moderate drinkers, according to a report published in the American Journal of Nutrition that tested around 500 elderly women, have 12 to 16 percent higher bone mineral density than nondrinkers.

Finnish scientists tested 143 men aged 54-63 to see the effects of wine on bone mineral density and compared to nondrinkers, the men who drank a glass or two a day showed signs of greater bone mineral density.

 

Red wine can help protect the skin from sunburn

Flavonoids in wine are the compounds that help protect our skin.

When UV rays hit human skin the result is seen in oxidizing fats, DNA, and other molecules. Once this occurs, other enzymes are stimulated and can harm skin cells. Antioxidants in red wine play an important role in preventing oxidative stress.

Scientists from the University of Barcelona have discovered that drinking wine can help to lessen the effects of ultraviolet rays and protect the skin from severe sunburn.

 

Red wine can prevent blindness and eye diseases

Given resveratrol is responsible for stopping the growth of the blood vessel, it can prevent age-related macular degeneration and diabetic retinopathy, the researchers at Washington University School of Medicine concluded.

A great deal of research has identified resveratrol as an anti-aging compound.

A study of 1,379 individuals in Iceland, which was published in Nature, found that moderate drinkers are 32 percent less likely to get cataracts than nondrinkers.

 

Red wine can help to slow down the aging process

We can say that red wine promotes longevity.

A Finnish study of 2,468 men over a 29-year period, which was published in the Journals of Gerontology, found that wine drinkers have a 34 percent lower mortality rate than beer drinkers.

Another in vitro study conducted by the researchers at Harvard Medical School showed that resveratrol is linked to increased health and longer life span.

 

Red wine plays an important role in protecting against prostate cancer

Red wine plays an important role in protecting against prostate cancer
The study shows that men who drink an average of four to seven glasses of red wine per week are 52% as likely to be diagnosed with prostate cancer.

The researchers believe that compounds resveratrol and flavonoids are responsible for this protective role. More research is needed to prove the findings.

 

Red wine can prevent breast cancer

Unlike most alcoholic beverages, red wine can help to prevent breast cancer, according to the researchers from Cedars-Sinai Medical Center.

The scientists found out that chemicals in the seeds of red grapes can reduce estrogen levels in premenopausal women, increasing their testosterone levels. This seems to be the perfect condition for lowering the risks of developing breast cancer.

“If you were to have a glass of wine with dinner, you may want to consider a glass of red,” said Chrisandra Shufelt, MD, one of the study’s co-authors.¬† “Switching may shift your risk.”

Authors of the study explained that eating red grapes would have the same positive effects.

 

Red wine can protect against lung cancer

Unfortunately, lung cancer is the most common cause of death around the world. It is also the newly diagnosed cancer. This makes the matter more devastating given that smoking is the most common cause and that percentage of smokers is increasing every year.

However, different causes can increase the risks, although tobacco smoking is the most common factor for the disease.

This is the founding from the first meta-analysis that examines the separate effects of alcoholic beverages on lung cancer risk:

“An antioxidant component in red wine may be protective of lung cancer, particularly among smokers,” according to Chun Chao, Ph.D., one of the authors of this study.

 

Red wine can prevent bowel cancer

The compound responsible for decreasing the risk of developing bowel cancer is resveratrol.

Drinking two glasses of red wine a day can reduce the rate of bowel cancer by around 50%, according to the scientists from the University of Leicester.

“It’s a fascinating study but we need much more research to understand all the pros and cons of someone taking resveratrol to prevent bowel cancer.

However, we do know that keeping a healthy weight along with a balanced diet low in red and processed meat with lots of fiber including fruit and vegetables can stack the odds in your favor to lower your risk of developing the disease.”

 

Red wine can improve short-term memory

Once again, the magic compound behind this health benefits is resveratrol.

Wine can improve problem-solving and reasoning skills, researchers showed in a study. It appears that light and moderate drinkers showed less memory decline than non-drinkers.

Resveratrol seems to impact the portion of the brain associated with the formation of new memories and learning.

 

Red wine could help burn fat

It seems that a certain type of red wine, Red Muscadine, native to the southeastern US, contains ellagic acid that could help with weight loss.

Apart from this type of wine, ellagic acid is found in raspberries, blackberries, walnuts and pecans and green tea. One study showed that ellagic acid can prevent the development of cancer cells.

This is promising news, however, a study from Oregon State University tested the impact on the fat cells on overweight mice. More research is needed to be able to show that rare red wine can be beneficial to humans.
