Fiber affects blood sugar and diabetes management. So how:
Slowing Carbohydrate Absorption: When coupled with water in the digestive tract, fiber, especially soluble fiber from oats, lentils, and certain fruits and vegetables, forms a gel.
This gel inhibits carbohydrate digestion and absorption, releasing glucose slowly into the bloodstream. Fiber can reduce blood sugar rises after meals, which is especially advantageous for diabetics.
Fiber-rich diets may enhance insulin sensitivity, helping cells respond to insulin and manage blood sugar. This can help diabetics maintain their blood sugar and reduce their insulin use.
Reducing Food Glycemic Index: The GI measures how rapidly carbs elevate blood sugar. High-GI foods generate quick blood sugar spikes, while low-GI foods cause moderate increases.
High-fiber diets have a lower glycemic index because fiber delays carbohydrate absorption. Diabetes patients can improve blood sugar control by eating more fiber-rich foods, which lower the glycemic load of their meals.
Fiber-rich foods are more full and reduce cravings. Managing weight and calorie intake can help diabetics maintain stable blood sugar levels.
Increased fiber intake from fruits, vegetables, whole grains, legumes, nuts, and seeds can help diabetics control blood sugar, improve insulin sensitivity, increase satiety, and improve overall health.
