Amazingly, what you eat changes your cholesterol level. And your risk for fatal heart attack, if you have heart disease.
It's well known that trans fats (the icing on a donut, the dry creamer in the break room, the deep fried onion rings at the diner) raise lousy (LDL) cholesterol, and lower HDL (healthy) cholesterol.
It's less well known that all alcohol raises HDL, and that soy nuts lower LDL: if you have risk for alcoholism, or have liver disease, skip the booze; but if not, alcohol (beer, wine, spirits, cider) can be a healthy way to being to tell your genes what to do. And your cholesterol level and cardiologist will thank you.
