High Fiber Foods for Diabetics: 10 Dietitian Recommended Foods

Published on: 05/02/2023

For those with diabetes, managing blood sugar levels can be a challenge. One way to help manage blood sugar levels is to include high fiber foods in your diet. High fiber foods can help regulate blood sugar levels, improve insulin sensitivity, and reduce the risk of complications associated with diabetes. In this blog post, we will explore the top high fiber foods for those with diabetes and how to incorporate them into your diet.

The Role of Fiber in Diabetes

Fiber is a type of carbohydrate that your body cannot digest. Instead, it passes through your digestive system mostly intact. This can help regulate your blood sugar levels in several ways:

  • Slows down digestion: High fiber foods take longer to digest, which means that glucose (sugar) is released into your bloodstream more slowly. This helps prevent spikes in blood sugar levels.
  • Improves insulin sensitivity: Eating high fiber foods can help improve your body’s sensitivity to insulin. This hormone helps your cells absorb glucose from your bloodstream, which can help lower your blood sugar levels.
  • Promotes fullness: High fiber foods can help you feel fuller for longer, which can prevent overeating and help you maintain a healthy weight. This is important because excess weight can make it harder to manage your blood sugar levels.

  1. Legumes – beans, lentils, and peas 
  2. Berries – strawberries, raspberries, and blueberries 
  3. Whole grains – oatmeal, quinoa, and brown rice
