What is a “serving” of food in a diabetic diet?

Are people with diabetes confused about how much food they can eat? First, it is important to know how much a serving of food is. The facts may be different than expected.

Suppose you eat a cup of rice at dinner, but a serving is actually 1/3 cup. So that’s 3 times the amount of carbohydrates you think you’re getting.

To avoid this mistake, it is important to know exactly how much is in a serving. Talk to a dietitian or diabetes educator.
