Really ? The research to date has been very mixed with quite a number of investigations that haven’t found a protective effect for red wine or other alcohol, probably because of the difficulty of doing studies in which people often do not tell scientists and doctors how much they really drink. The Penn results are just the largest sample showing significant harm to the heart in even moderate intake. The genetic component was due to not being able to tolerate alcohol, not better genes overall. I may or may not discontinue my habit of 2-3 oz of red wine a day (60-70 ml?) but it is good to know this just seems to be another case where you get a lot of hype about health benefits that doesn’t stand the test of time.
I wonder if it has anything to do with alcohol tolerance. The heart has brain cells in it. Males and females have different tolerances, too. I would think when it comes to what we eat, we should follow our ancestor’s diet. If they live a long time, do what they did. If you are of mixed heritage, good luck. Gene studies will someday tell you what you are good for. The one thing I learned about genes that I didn’t know is some can turn on and off.
Sorry about missing the tolerance statement in your post. Must be having a low sugar crash. Too much maple syrup in my oatmeal? Get loopy. When I re-read your post I realized I wasn’t far off. Better go get some meat to offset my sugar.
