Cholesterol is a tricky thing—there's good cholesterol and bad cholesterol—you want the good kind, HDL cholesterol, but not the bad kind—LDL cholesterol. Well, good news: it turns out red wine can increase levels of HDL cholesterol...the good kind.
A recent study published in the Annals of Internal Medicine, reported on a group of 224 volunteers, who were variously told to drink 5oz of mineral water, dry white wine, or dry red wine for two years with dinner. At the end of the study, Time reports that "the red wine drinkers had significantly increased their levels of good HDL cholesterol and had a more beneficial cholesterol ratio compared to the group that drank water."
The study went on to say that the red wine drinkers "reported better sleep quality than the group that drank water" and had lower cardiometabolic risk factors.
