1. In the right amounts, alcohol lowers LDL ("bad" cholesterol) and raises HDL ("good" cholesterol). This effect does not require that the alcohol come from wine, though it is more likely that the drinking pattern will be a healthy one if it is.
2. Alcohol raises levels of heart-healthy omega-3 fatty acids. This is a relatively recent discovery but potentially very important. Have some wild (not farmed) salmon with a glass or two of pinot noir and you are on your way.
3. Wine drinkers have lower health care costs. This may seem obvious to those who have an interest in the science of healthy drinking, but it has been documented in a study by Medicare. In a review of health care costs related to drinking, they found that those drinking 6-13 glasses of wine per week had annual expenses about $2000 less than nondrinkers.
