This chart, entitled “Comparison of Foods and their Impact on Blood Sugar,” is a visual tool designed to show how different foods can affect blood glucose levels. Using the Glycemic Index (GI) as an indicator, the chart compares common foods such as white bread, rice, potato, ripe banana, carrot, apple, lentils, nuts, plain yogurt, broccoli and corn tortillas.

  • High GI foods: Products such as white bread and potato are observed to have elevated values, suggesting a greater potential to rapidly raise blood sugar.
  • Low GI Foods: Options such as nuts, broccoli and plain yogurt show much less impact, making them ideal for those seeking to maintain stable glucose levels.
  • Expanded Comparison: The inclusion of corn tortillas provides an important benchmark, especially in traditional diets, helping to choose options that are better for metabolic health.


Overall, this chart allows you to quickly and easily identify which foods may help or hinder glycemic control, providing a useful guide for planning a balanced and health-conscious diet.
