However, there are some considerations to make when picking grapes: white wine typically contains fewer carbohydrates than red wine, which makes a small difference in terms of calories, says Caroline Cederquist, MD, author of The MD Factor and creator of bistroMD. Meanwhile, red wine is richer in antioxidants, and a 2014 study in The Journal of Nutritional Biochemistry, red wine's ellagic acids delay the growth of fat cells while slowing the development of new ones.
