Some studies have found that one or two glasses of wine per day may have cardio-protective benefits if you do not already suffer from a medical condition that precludes you from drinking alcohol. Red wine contains antioxidants that may increase the amount of ‘good’ cholesterol (HDL) and decrease the amount of ‘bad’ cholesterol (LDL) and/or reduce blood clotting.
Why is this? Drier wines like Cabarnet Sauvignon or Petit Syrah contain more of the flavonoids from the skin of the grapes chosen to make these red wines. The sweeter the wine, the smaller the concentration of flavonoids- this explains why white wine hasn’t been shown to be particularly cardio-protective. Drink safely but intelligently- always stay within your limits.
