There are many tasty snack ideas for diabetics; you just need to find the items you like. How about an apple with peanut butter? - weird but wondeful! A great alternative to peanut butter is almond butter, which is great on high-fiber crackers like ones made with rye flour. Or make your own snack mix out of a variety of nuts and dried fruit! Try grapes and feta cheese with balsamic vinegar.
If you have diabetes, you should try to cut out alcohol or talk to your doctor if you can not. Alcohol can cause low blood sugar, which is called hypoglycemia. The effects can be very hard to predict with different people. Doctors will allow some people to have a drink or two with proper management, but it is best to avoid alcohol altogether.
