Half glass of wine a day – good for longevity or bad because of increased cancer risk?

The answer depends on the study.  As far back as 1997, epidemiological studies suggested that moderate regular consumption of wine, red wine in particular, was associated with decreased risk of ischemic heart disease death(ref).   Then there is the often-cited 2007 study done by researchers at Wageningen University in the Netherlands of 1373 men born between 1900 and 1920(ref).  That study showed that, compared with men who did not consume alcoholic beverages, wine drinkers lived an average 3.8 years longer. Dr. Daan Kromhout, a senior author of the the study and vice president of the Health Council of The Netherlands is reported to have said “– men who drank about a half a glass of wine a day had a 40% reduction in all cause mortality and a 48% lower incidence of cardiovascular death.” 

On the other hand, it appears that women who drink just one small glass of wine a day significantly increase their risk of getting a number of cancers.  This is according to an article in the Feb 24, 2009 issue of the Journal of the National Cancer Institute reporting on a study of 1,280,296 middle-aged women conducted at the University of Oxford in the UK.  Of the women who drank, the average intake was the equivalent to a small glass of wine or 8g of alcohol. Drinking is estimated to result in 7,000 additional cancer deaths a year in the UK, 15 extra cases of cancer per 1,000 women(ref).  Rates of breast, oral, rectal, oesophageal, laryngeal and liver cancer were higher in the wine-drinking group.   “In an editorial published alongside the research, Michael Lauer and Paul Sorlie at the National Heart, Lung and Blood Institute in Maryland, US, write: ‘From the standpoint of cancer risk the message of this report could not be clearer. There is no level of alcohol consumption that can be considered safe.’” 

So what is going on here?  Is drinking a little red wine daily very good for the longevity of Dutch men but quite bad for British women?  Is there a critical health difference between drinking a half-glass and a full glass?  If Dutch men can be equated with British women, do the two studies taken together say the cardiovascular benefit of drinking the daily shot of wine exceeds the increased cancer risk?  Or should the British study be paid more attention to because of its much larger population sample?  Or perhaps the Dutch gentlemen were drinking better organic wines than cheaper stuff the English ladies were drinking.  Were the English ladies possibly imbibing wines with carcinogenic contaminants or additives?  Grapes can absorb pesticides and arsenic from the soil and wine can be contaminated by ochratoxin, or aflatoxin, all of which promote cancers.  It is enough to get me dizzy without drinking any wine at all. 

Personally, I might  drink a half-glass of red wine once or twice a month.  However, I take trans-resveratrol capsules twice daily without fail. 

About Vince Giuliano

Being a follower, connoisseur, and interpreter of longevity research is my latest career, since 2007. I believe I am unique among the researchers and writers in the aging sciences community in one critical respect. That is, I personally practice the anti-aging interventions that I preach and that has kept me healthy, young, active and highly involved at my age, now 93. I am as productive as I was at age 45. I don’t know of anybody else active in that community in my age bracket. In particular, I have focused on the importance of controlling chronic inflammation for healthy aging, and have written a number of articles on that subject in this blog. In 2014, I created a dietary supplement to further this objective. In 2019, two family colleagues and I started up Synergy Bioherbals, a dietary supplement company that is now selling this product. In earlier reincarnations of my career. I was Founding Dean of a graduate school and a full University Professor at the State University of New York, a senior consultant working in a variety of fields at Arthur D. Little, Inc., Chief Scientist and C00 of Mirror Systems, a software company, and an international Internet consultant. I got off the ground with one of the earliest PhD's from Harvard in a field later to become known as computer science. Because there was no academic field of computer science at the time, to get through I had to qualify myself in hard sciences, so my studies focused heavily on quantum physics. In various ways I contributed to the Computer Revolution starting in the 1950s and the Internet Revolution starting in the late 1980s. I am now engaged in doing the same for The Longevity Revolution. I have published something like 200 books and papers as well as over 430 substantive.entries in this blog, and have enjoyed various periods of notoriety. If you do a Google search on Vincent E. Giuliano, most if not all of the entries on the first few pages that come up will be ones relating to me. I have a general writings site at www.vincegiuliano.com and an extensive site of my art at www.giulianoart.com. Please note that I have recently changed my mailbox to vegiuliano@agingsciences.com.
