Use your NutriKit® life-sized food images to show the glycemic index of foods Diabetes patients should know the differences in carbohydrates and how they affect their blood sugar. Choosing carbohydrates that can help maintain normal blood sugar is important to avoid complications. One way to achieve this is by consuming food with low glycemic index. Glycemic index compares the effect of food in blood sugar with the effect of pure glucose in blood sugar. Use your NutrikitUSA life-sized food images to encourage consuming low glycemic index foods instead of high-glycemic index foods.
