There are two main types of nutrients you obtain from foods:
Carbohydrates are the body’s preferred source of energy; in fact, our brains only use glucose, a carbohydrate, for energy. 100% of carbohydrate sources consumed turn into glucose in the bloodstream, making carbohydrates the food group that impacts your blood sugar the most.
People with diabetes need carbohydrates and can have sugars and starches; however, portions should be limited and spread throughout the day. The types of carbohydrates and amounts you should consume should be individualized. Some medications used to treat diabetes will require you to eat carbohydrates consistently at each meal. Your healthcare team will help you evaluate and determine how much carbohydrates you should consume and the timing of meals based on your health goals and blood sugar patterns.
Protein is used in small amounts by the body for the healing and repair of body tissues, including muscle tissues. Protein does not directly make blood sugars go up. Including protein at a meal or snack can help stabilize blood sugars longer by slowing the absorption of carbohydrates into the bloodstream and helping you feel fuller for longer. Protein sources should include lean meats or meat substitutes that are plant-based/vegetarian prepared without large amounts of fat —avoid frying and trim visible fat.
Fat is used in the body to help protect our organs and insulate the body to maintain body temperature. We cannot eliminate fat from our diet; however, it contains large amounts of calories causing weight gain, and some fat types can increase your risk of heart disease. Fats may need to be limited, and you should focus on the types of fats you consume. Try to consume more unsaturated fats than saturated and trans fats. In general, fat in the diet does not directly make blood sugar increase, but fat can indirectly impact diabetes by increasing weight and, in turn, increasing insulin resistance.
