Fiber plays a significant role in managing diabetes. It helps regulate blood sugar levels by slowing down the absorption of sugar into the bloodstream. High-fiber foods, such as whole grains, fruits, vegetables, and legumes, can also improve digestion and promote a feeling of fullness, which may help with weight management. Including fiber-rich foods in your diet can contribute to better overall health and aid in controlling blood sugar levels. Aim for at least 30 grams of fiber daily, and consult your GP or a registered dietitian for personalized dietary advice.
