Bring on the Rioja
The latest research is suggesting that substances specifically found in red wine may help prevent heart disease, fight tooth decay and help with a host of other ailments. Several studies have demonstrated that the substance resveratrol, which is present in the skin of the grape, has a protective effect against cardiovascular diseases. It seems that at least part of the protective effect can be explained by the fact that resveratrol inhibits the formation of inflammatory factors.
Cardiovascular disorders, such as heart attacks and strokes, frequently occur in association with chronic inflammatory diseases, such as arthritis. The natural substance resveratrol has major therapeutic potential, particularly when it comes to the treatment of inflammatory diseases that can cause serious damage to the cardiovascular system.
Another recent study found that red wine, as well as grape seed extract, could potentially help prevent cavities. The report, which was published in the Journal of Agricultural and Food Chemistry, could lead to the development of natural products that ward off dental diseases with fewer side effects.
Cavities, periodontal disease and tooth loss affect an estimated 60 to 90 per cent of the global population. The problems start when certain bacteria in the mouth get together and form biofilms (communities of bacteria that are difficult to kill). The biofilms form plaque and produce acid, which starts damaging teeth. Brushing, fluoride in toothpaste and water, and other methods can help get rid of bacterial plaques, but the effects are limited. Currently used antimicrobial rinses can change the colour of the gums and alter taste. Subsequently, many people don’t use them for as long as they should.
The researchers found that polyphenols, grape seed extract and red wine were the most effective at getting rid of the bacteria. The study suggested that regular intake of resveratrol may be highly beneficial in preventing tooth loss.
“The benefits of red wine are well documented,” said Dr. David Prelutsky, who is with Washington University School of Medicine in St. Louis (Missouri). “However, moderation is the key and you can’t go overboard every night. It is also best to have some food with red wine. It may be the combination of resveratrol and other substances that produce the beneficial effect. The Spanish have it right with combining it with tapas.”
Another recent article published in the journal Advances in Experimental Medicine and Biology found that resveratrol may prevent cancer as well. The researchers found that resveratrol had significant anti-cancer effects. Currently, clinical trials are testing the ability of resveratrol to prevent colon and liver cancer. Further studies are also planned for head and neck cancers.
