Final answer:
Carbohydrate counting is a method used by individuals with diabetes to manage their blood sugar levels and prevent low or high blood sugar levels.
Step-by-step explanation:
Carbohydrate counting is a method used by individuals with diabetes to manage their blood sugar levels. By keeping track of the number of carbohydrates consumed, individuals can adjust their insulin dosage accordingly and prevent both low and high blood sugar levels. This is because carbohydrates are the main nutrient that affects blood sugar levels.
When carbohydrates are consumed, they are broken down into glucose, which is then released into the bloodstream. If too few carbohydrates are consumed, blood sugar levels may drop too low, leading to hypoglycemia. On the other hand, if too many carbohydrates are consumed, blood sugar levels may rise too high, leading to hyperglycemia.
