Dietary Fiber and Healthy Blood Sugar Response

Dietary Fiber and Healthy Blood Sugar Response

Dietary fiber is an important part of a healthy eating pattern. Although it is often associated with digestive health, it can also help support a healthier blood sugar response after meals.

What is dietary fiber?

Dietary fiber is a type of non-digestible carbohydrate found naturally in plant foods, and ‎fibers can also be added to foods. Unlike sugars and starches, fiber is generally not ‎digested or absorbed in the small intestine and has effects that are beneficial to human ‎health. Different fibers work in different ways, which is why eating a variety of fiber-‎containing foods is important.‎

How dietary fiber helps support a healthy blood sugar response

  • Slows digestion: ‎ Some fibers form a gel-like substance in the stomach and small intestine, slowing ‎the passage of ingested food and how quickly nutrients move into the bloodstream.‎
  • Helps steady blood sugar after meals: By slowing carbohydrate absorption, fiber may help reduce rapid post-meal increases in blood glucose.
  • Supports your body’s insulin response: Fiber may help reduce the amount of insulin needed after a meal by helping moderate the blood sugar rise.

How to identify dietary fiber for this benefit

  • Check the Nutrition Facts label: Look for the amount of “Dietary Fiber” listed per serving.
  • Compare similar products: Choosing options with more dietary fiber may help support a healthier blood sugar response after meals.
  • Review the ingredient list: Added fiber ingredients such as beta-glucan, inulin, pectin, polydextrose, psyllium, ‎resistant maltodextrin, resistant starch, and soluble corn fiber can contribute dietary ‎fiber.‎
  • resistant starch, soluble corn fiber, inulin, polydextrose, psyllium, beta-glucan, pectin, and resistant maltodextrin can contribute dietary fiber.
  • Increase gradually: Adding dietary fiber over time can help the digestive system adjust comfortably.

Fiber is about more than regularity. As part of a balanced eating pattern, it can help promote a healthier post-meal balance of blood sugar and insulin.
