This condition, which is known as insulin resistance, causes sugar and insulin levels to remain high for longer periods after a meal.<\/p>\n<p>Over time, the increasing demands made on the insulin producing cells in the pancreas wears them out, and insulin production eventually stops. So, foods that increase blood sugar levels by a large amount in a short span of time puts more stress on the body\u2019s insulin production and can be detrimental in people with diabetes.<\/p>\n<p>The glycemic index (GI) is a rating system for foods containing carbohydrates. It shows how quickly each food affects your <a href=\"https:\/\/www.suburbandiagnostics.com\/health-library\/diabetes\">blood sugar<\/a> (glucose) level when that food is eaten on its own. The rating ranges from 0 to 100, with 100 representing the blood sugar rise when pure glucose is consumed.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_86 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.suburbandiagnostics.com\/blog\/type-2-diabetes-and-glycemic-index\/#Low_medium_and_high_GI\" >Low, medium and high GI<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.suburbandiagnostics.com\/blog\/type-2-diabetes-and-glycemic-index\/#Risks_of_a_High_Glycemic_Index_Diet\" >Risks of a High Glycemic Index Diet<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.suburbandiagnostics.com\/blog\/type-2-diabetes-and-glycemic-index\/#Factors_Affecting_the_Glycemic_Index\" >Factors Affecting the Glycemic Index<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/www.suburbandiagnostics.com\/blog\/type-2-diabetes-and-glycemic-index\/#Recommendation_on_Glycemic_Index_for_Diabetics\" >Recommendation on Glycemic Index for Diabetics<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/www.suburbandiagnostics.com\/blog\/type-2-diabetes-and-glycemic-index\/#How_can_you_find_the_Glycemic_Index_of_a_food_item\" >How can you find the Glycemic Index of a food item?<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Low_medium_and_high_GI\"><\/span><strong>Low, medium and high GI<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>Low-GI foods: Glycemic index &lt; 55<\/li>\n<li>Medium-GI foods: Glycemic index is 56-69<\/li>\n<li>High -GI foods: Glycemic index is 70-100<\/li>\n<\/ul>\n<p>A low glycemic index food will cause a slow, gradual increase in blood sugar levels and will maintain increased energy levels for a longer duration.
