Just a few health benefits of drinking wine:

- While wine offers certain medical benefits, it may slightly increase the risk of contracting certain kinds of cancer of the digestive tract, particularly the esophagus. There is also a slightly increased risk of breast cancer.

- Red wine, typically more than white wine, has antioxidant properties and contains resveratrol, which seems to be important in the cardio-protective effects of wine.
