Resveratrol: good, bad or just plain hype?

Resveratrol: good, bad or just plain hype? | casaveneracion.com

An article that says ingesting resveratrol may be the equivalent of working out in the gym has gained some 1.8 million shares on various social networks. “A glass of red wine is the equivalent to an hour at the gym, says new study” published on January 15, 2015 in My Daily cites a Science Daily article dated June 19, 2012 as its source.

The Science Daily link to “materials” from University of Alberta Faculty of Medicine & Dentistry lands on a 404 page. A search in the University of Alberta Faculty of Medicine & Dentistry using “resveratrol” as the keyword leads to “Resveratrol may be a natural exercise performance enhancer” published on June 19, 2012. Nowhere in the article is it said, or implied, that “a glass of red wine is the equivalent to an hour at the gym”. How My Style writer Daisy May Sitch [described as “all about vintage leather, oversized anything (handbags), coffee and ‘The Way We Were'”] reached that conclusion is unclear.

Is the 2012 University of Alberta study still authoritative?

In July of 2013, a University of Copenhagen study led to the conclusion that “in older men, a natural antioxidant compound found in red grapes and other plants – called resveratrol – blocks many of the cardiovascular benefits of exercise.”

A 2014 study in another Canadian university was quoted in in October 29, 2014 article in The Queen’s Gazette.

Sixteen participants who engaged in less than three hours of aerobic exercise per week at the time of enrolment were asked to perform HIIT three times per week for four weeks. During this time, participants were administered daily doses of either RSV or a placebo.

Results after the four-week study showed that RSV supplementation may actually oppose the effects of exercise alone. In fact, the placebo group showed an increase in some of the benefits associated with physical activity as opposed to the group taking RSV whose physical fitness didn’t improve.

Going back to Daisy May Sitch’s srticle in My Style, there an “update link” to a February 11, 2015 article written by My Style Acting Editor Katie Jones which points to another Science Daily article that rehashes an Oregon State University article published on February 4, 2015.

Drinking red grape juice or wine – in moderation – could improve the health of overweight people by helping them burn fat better, according to a new study coauthored by an Oregon State University researcher.

Why the confusing findings?

One factor is the methodology used in each study. Another factor which is rarely mentioned in “scientific” studies, is where the funding from the study comes from. In the 2012 University of Alberta study, principal researcher Jason Dyck was quoted as saying that “We immediately saw the potential for this and thought that we identified ‘improved exercise performance in a pill.'”

And that’s the operative word right there — PILL. If you can’t smell the presence of pharmaceutical companies, you should have your cognitive faculties checked. Drug companies fund a lot of this studies to find out just what can be transformed into pills that they can manufacture, hyped up and sell at exorbitant prices.
