The recommendation that one-half of an individual's grain intake should come from whole grains is based on their numerous health benefits, especially for individuals with diabetes. Whole grains are less processed than refined grains, which means they retain more of their natural nutrients, including fiber, vitamins, and minerals. The higher fiber content in whole grains helps regulate blood sugar levels by slowing down the digestion and absorption of carbohydrates, which can prevent spikes in blood glucose.

In addition, whole grains can promote feelings of fullness, thereby aiding in weight management—an important factor for individuals managing diabetes. They also have an overall positive effect on heart health, which is particularly important, since individuals with diabetes are at a higher risk for cardiovascular disease.

While refined grains, sugary grains, and gluten-free grains do have their places in certain diets, they typically do not offer the same health benefits as whole grains. Refined grains often lack the fiber and nutrients present in whole grains. Sugary grains can lead to increased blood sugar levels due to their high sugar content, and gluten-free grains may not provide the same nutritional benefits as whole grains unless specifically fortified.
