Eating a healthy diet is important for managing type 2 diabetes as it can help control blood sugar and weight, prevent complications, and potentially reduce medication needs. Nutrition guidelines recommend consuming at least 130 grams of carbohydrates per day primarily from fruits, vegetables, whole grains and low-fat dairy, monitoring carbohydrate intake, limiting saturated and trans fats, and engaging in regular exercise. Individualized medical nutrition therapy is needed based on a person's health status and goals.
