New Heart Association Survey on wine: Why are Americans confused about healthy drinking?

The American Heart Association recently released the results of a survey of Americans on their knowledge of healthy drinking and consumption of sea salt. No surprise, they concluded that we have it all wrong. On the plus side, two thirds agreed with the statement that wine is good for the heart, but less than one third know the AHA’s recommended limits of a daily glass or two for men and no more than one for women. The survey showed that “we need to do a better job of educating people about the heart-health risks of overconsumption of wine” according to a spokesperson.


I say bless their hearts but their paternalistic message only adds to the confusion. For starters, they don’t even have their definitions right, which is a 5-ounce pour as the standard on which research and policymakers have long agreed, but the AHA cuts it back to 4. Granted, they have come a long way since the mid 1990’s when the official policy grudgingly acknowledged that a glass or two a day “might be considered safe” while hastening to add a disclaimer about all of the social ills attributed to alcohol consumption. But these problems are associated with excess and problem drinking, not a glass or two or even three with a leisurely dinner. What statistics consistently show is that wine with dinner is among the most powerful contributors to health.

Part of the problem is the narrow focus on heart health, which we can forgive to some degree for the AHA but it leads to an incomplete picture of the broader benefits of healthy drinking. When consumed with meals, up to 3 glasses for a man and about half that for a woman is associated with the greatest reduction in health problems across the board leading to longer lifespan and a higher quality of life, especially in old age.

Just as interesting to me is the comments that follow the various news postings about the study. It would seem that we are even more confused about wine and health now as ever, judging from remarks suggesting that red grape juice has the same benefits as wine without the alcohol.

Wear red and DRINK red for women’s heart health

This Friday Feb 2nd is the annual “wear red” day in Canada and the U.S. to raise awareness for women’s heart health. Why only a day for the number one threat to women’s health? Women are 5 times more likely to succumb to heart disease than breast cancer, which gets a whole month (October.) Another contradiction is that the advice women hear about prevention of breast cancer is the opposite of what you can do to lower the risk of heart disease: a daily glass of wine. Even one drink a day raises your risk of breast cancer, we are told, ignoring the overriding benefits of wine on heart health. Drink red wine to live longer Here’s why I think women should also “drink red.” For starters, wine helps de-stress and celebrates life. Stress is a factor in heart disease, and if that were the only way wine helped it would be worth considering. But the medical evidence is also strong: a daily glass of red wine helps raise the HDL “good cholesterol” levels, which lowers the risk of cardiovascular p…

Which types of wine are the healthiest?

I am often asked after lecturing on the healthful properties of wine which type is best to drink. Since much of the discussion has to do with the polyphenol antioxidants from the skins and seeds of the grape, red wine is the first criterion since it is fermented with the whole grape rather than the pressed juice. This allows for extraction and concentration of these compounds, familiar ones being resveratrol and tannins. But beyond that, which varietals have the highest concentrations?


According to the Roman philosopher Pliny the Elder, “The best kind of wine is that which is pleasant to him that drinks it” but modern science expects more specifics. (The point of course is that if you have a wine that you enjoy you are more likely to drink regularly and therefore reap the benefits.) But there are several difficulties in singling out certain wines for their healthful properties. Which compounds to measure? Are we talking about heart health or the whole gamut? Is it the varietal of the …

The J-curve is dead. Long live the J-curve!

There is a resurgence of debate about the validity of the J-curve, especially as it relates to alcohol and cancer. A 2014 report determined that “alcohol use was positively associated with overall mortality, alcohol-related cancers, and violent death and injuries, but marginally to CVD/CHD” (cardiovascular disease). In other words, there was little benefit if any in terms of heart disease but a big upside risk for cancer and accidental or violent demise. Gone was the French Paradox! The J curve is dead! Or not. Though that statement may be technically true, I looked at look at the data myself and found something different: a strong confirmation of the J-curve for overall mortality, overall cancer deaths, cardiovascular disease, and all “other causes.” This held for both men and women:
