Glycemic Index Chart and Effects of Low and High GI Foods

Published on
By : dLife Editors

The Glycemic Index (GI) is a scale often used to classify and rank carbohydrate-rich foods based on how fast they affect blood sugar levels in a window of 2-3 hours after a meal.

While the foods high in glycemic index break down quickly to raise your blood sugar rapidly, foods with low GI take a longer time to be digested and absorbed.

This results in a gradual and slower change in blood sugar levels. When it comes to managing diabetes, it’s a great benefit to building your diet around the glycemic index of such foods involved in the diet.

Carbohydrates having a high GI will cause a rapid increase in blood sugar, whereas diet based and built around low GI are low in sugar but considerably high in fiber. Because the low GI foods cause a slow rise in blood sugar they are, therefore, considered to be more ideally suited for people living with diabetes.

Effects of eating low GI foods

  • It enhances natural weight loss
  • It increases the body’s sensitivity to insulin
  • Help keep cholesterol level under check
  • Reduces the risk of heart diseases
  • Help refuel carbs stores after intense exercise

Effect of eating high GI foods

  • It could cause cell dysfunction
  • Increase the production of insulin
  • Encourages the accumulation of free fatty acid in the body
  • Raises the risk for type 2 diabetes and obesity

Glycemic Index Chart

As already explained, foods with low GI tends to be less stressful on the body compared to high GI foods, especially for people with diabetes. Below is a glycemic index chart to help you tell the GI number of that your favorite food. The chart is courtesy of Healthiack.

Knowing the Glycemic Index of your foods is a great way to manage diabetes. You need to know that low GI foods are foods with 55 or less glycemic index, 56 to 69 signifies the food is a medium GI food, and foods with 70 and above glycemic index are high GI foods and should be avoided with all consciousness.
