The short answer to the question posed in the title is attributed to Ben Franklin-“Believe none of what you hear and half of what you see” (or read).First, recognize that research (could apply to any research) concerning the effects of alcohol on one’s well-being, could be initiated and conducted with various degrees of bias. For example, I recently noticed conflicting research data from two seemingly benign sources concerning the benefits, or lack of, in alcohol consumption เหล้านอก. Two somewhat contradictory articles were published on August 22nd and 24th, 2018. Both studies appeared in the Health section on the Newsmax website on August 24, 2018.
The lead article on the 24th had a headline: “No Safe Level of Alcohol”, the other appeared on the 22nd: “Moderate Drinking May Protect Your Health”. With just the information implied by the titles, what take-aways should the reader be left to contemplate?What is the consumer to believe? For years I have been writing on conflicted studies relative to the benefits of drinking wine and alcohol in general. I find the disparity in studies can have a deleterious effect on making reasoned decisions from information in such studies. If you enjoy consuming some alcoholic beverages, you are no doubt interested in the long-term effects. But, based on never-ending studies covering both sides of the issue, it is hard to have much faith in any one study or even arrive at a reasonable conclusion.
Most benefits of wine consumption are centered around cardiovascular benefits. A French scientist studied wine and grape seeds/skins for decades. He was widely published relative to the anti-oxidant benefits from wine, and grape seeds in particular. His conclusions in the 80’s was that the benefits of wine, especially grape seed extracts, were remarkable relative to heart health, vascular system, and skin elasticity, to name a few. “In 1985, Jack Masquelier was able to further explain the intense and instant positive effects that OPCs (an anti-oxidant compound in grape seeds/skin and wine) have on the human body when he discovered that OPCs neutralize free radicals, the common cause of degenerative conditions and early onset of age-associated changes in the body.”
The point being; seeds and skin of grapes have high concentrations of OPC’s and while drinking wine has some anti-oxidant values (derived primarily from resveratrol) most are found in grape skin and seeds. In fact, there are some large wine producers (Gallo being one) also producing grape seed extract for the supplement industry. Also, resveratrol is being used in some topical anti-ageing skin products.
