Is Resveratrol In Wine Worth The Side Effects?
According to many studies which mostly are done by the alcohol industry, red wine in moderate levels, is claimed to have positive effects on the heart. The alcohol and resveratrol, which is a potent antioxidant, are supposed to help reduce the incidence of heart diseases and even cancer by increasing levels of high density lipoprotein (HDL) levels or the “good cholesterol” in the body protecting against artery destruction.
Despite the news that red wine might be healthy to drink many doctors and scientist are still holding off regarding advocacy of drinking alcohol as alcohol can cause cancer and damage the nervous system. But more recently, studies attempt to find out more about Resveratrol which is the focus of numerous animal and human studies and its effects to the functioning of the body.
The effects of Resveratrol on the lifespan of many of these organisms still are controversial, with undefined effects upon examination of fruit flies, worms and short-lived fish. We cannot, however, disregard the fact that Resveratrol is now associated with anti-cancer, anti-inflammatory, blood sugar lowering and other cardiovascular benefits when tested with animals. But then again, much of these results have yet to be applied in more human studies in order to strongly support the benefits observed in animal trials.
What Is Resveratrol?
Resveratrol is a substance found in skins of red grapes thus can be found red wine. Other significant sources of Resveratrol include peanuts; peanut products and the Japanese knotweed, where Resveratrol has been derived from, through chemical synthesis, and are sold as nutritional supplements by pharmaceutical companies around the world.
The effects observed with Resveratrol primarily come from animal experiments. In the year 2003, certain groups published findings that support Resveratrol’s effects to improve lifespan expectancy initially observed with certain yeast specie. Later on, the study was replicated through certain specie of nematodes, fruit flies and a short-lived fish with increased average life spans.
In 1997, topical applications of Resveratrol in mice prevented the development of skin cancer. As of today, there are no results of human experiments for cancer has been reported. So far, the strongest evidence that Resveratrol can prevent cancer development is if the substance actually comes in direct contact with the tumor such as tumors from the skin and gastrointestinal tract. As for other types of cancers, there is no clear evidence regarding the anti-tumor properties of the substance.
Other applications for Resveratrol are the level of improved endurance seen in mice receiving vigorous physical activity when compared to mice with no treatment of Resveratrol. Another study suggested that Resveratrol’s effects are similar to the improved but still uncertain lifespan expectancy that calorie restriction provides.
Overall, Resveratrol if not obtained from drinking alcohol is a very promising substance when it comes to health issues and the attempt to improve lifespan expectancy of humans but people have to be aware of the fact that studies are still inconclusive. How Resveratrol induces its effects to the body is still relatively unknown. Research into the potential heart and anti-cancer benefits of Resveratrol is still ongoing.
