Understanding Carb Counting
Why Count Carbs?
Carbohydrates have the most impact on blood glucose levels. Counting carbs helps you match insulin doses to the food you eat, which can help keep blood glucose levels within target range.
Reading Food Labels
Look for "Total Carbohydrates" on the nutrition label. Remember that sugar is already included in this number. For packaged foods, make sure to check the serving size.
Adjusting for Activity
Physical activity generally lowers blood glucose. You may need to adjust your insulin dose or eat additional carbs before exercise, depending on intensity and duration.
