The best beer for diabetics to drink is light beer, with a two-drinks-per-day limit for men and a one-drink-per-day limit for women, states the American Diabetes Association. One drink is equal to 12 ounces of beer. Diabetics who drink need to do so with food and keep water handy.
Diabetics need to avoid heavy craft beers, as they tend to have twice the calories and alcohol as light beers, notes the American Diabetes Association. Patients on insulin or diabetes medications, including meglitinides and sulfonylureas, which make more insulin to lower blood glucose, must be sure they eat with their drink, and not drink on an empty stomach or when their blood glucose is low.
