Resveratrol May Help Smokers Heart Health
Smoking is a major risk factor for heart disease. In fact, smokers are 2-4 times more likely to develop coronary heart disease than nonsmokers. A recent study found that supplementation with resveratrol may help improve cardiovascular health in smokers.
Participants in the study included 50 individuals between the ages of 20-50 who smoked at least five cigarettes daily, at least 20 packs per year, and drank at least 30 g of alcohol daily. Over the course of 30 days they were randomly assigned to take either 500 mg of resveratrol or a placebo. Following that phase, all of the participants switched interventions after a 30-day washout period.
At the conclusion of the study, the researchers noted the resveratrol group had a 50% reduction in C-reactive protein (a marker of inflammation) as well as decreased triglyceride concentrations and increased Total Antioxidant Status.
The researchers noted that the reduction in CRP seen here is notably higher than that seen in a previous study, which found that supplementation with 8 mg of resveratrol resulted in a 26% reduction. They therefore hypothesized that resveratrol has a dose dependent ability to reduce CRP levels.
Researchers from the University of Turin in Italy conducted the study. It was published in Volume 20, Issue 10 of Current Medicinal Chemistry.
Previous studies have shown resveratrol to be a powerful antioxidant with health benefits that include increasing energy levels, improving brain health, reducing the appearance of aging, lowering the risk of lung cancer, improving metabolism, regulating blood glucose levels in diabetics and improving liver function.
This antioxidant can be found in red wine, grapes, grape seed extract, and peanuts. A glass of red wine a day can provide a good amount of resveratrol, but excess drinking will reverse the positive health benefits. Another good way to get resveratrol is through a high quality supplement.
