A diabetic person can eat ice cream occasionally as long as he continues to adhere to the recommended carbohydrate intake for his individual meal plan, according to the American Diabetes Association. This usually involves cutting out other foods to make room for the ice cream.
If a diabetic person who typically consumes 60 grams of carbohydrate for dinner wants to include a modest serving of ice cream consisting of 15 grams of carbohydrate, he should ensure that the combined carbohydrate count of any other items he eats for dinner does not exceed 45 grams, explains the American Diabetes Association. He may have to reduce or eliminate high-carbohydrate foods such as bread, corn, rice, potatoes or legumes in that particular meal to achieve this goal. Ideally, a diabetic person should prioritize nutrient-rich foods in the majority of his meals and enjoy ice cream as an infrequent treat.
