Is alcohol good for the brain?

77. Continuing our line of thought on wine and the brain, we turn to the question of alcohol's effects. Haven't we always assumed that alcohol kills brain cells, and so any positive aspects of drinking must be weighed against this? True, at high doses alcohol (as with anything for that matter) is toxic, but a recent review from Loyola University pointed to experimental evidence that moderate alcohol levels exert direct "neuroprotective" actions; that is, in addition to promoting healthy blood vessels that improve blood flow to the brain, the direct effects of alcohol on nerve cells are protective, at least in moderate amounts.
Add this to the list of healthy effects of alcohol in moderation where cardiovascular disease is concerned, and keep it in mind the next time you see an ad for some supplement touting "all the benefits of wine without the alcohol" because that is of course not possible.

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:
