High Glycaemic Index Foods That Diabetics Should Avoid

Most diabetics are advised to eat low-glycaemic foods, considering they may spike blood sugar levels quickly and cause various other health problems. Therefore, it is imperative for most who are susceptible to diabetes or those who already have the condition. What is glycaemic index and what is its function? We give you a sneak peek of the foods that have high glycaemic index and are supposed to be avoided as much as possible.

According to Dr. Parul Srivastava, Nutritionist and Dietician, Eldercare, “The Glycaemic index is a value assigned to foods (carbohydrate), based on how slowly or quickly they affect blood glucose levels. Carbohydrates with a low GI value (55 or less) are more slowly digested, absorbed and metabolised and cause a lower and slower rise in blood glucose. Foods with high-glycaemic index numbers make blood sugar levels as well as insulin levels spike fast and subsequent rapid return to feeling hungry.” Senior Diabetes Educator, Kanika Malhotra agrees, “GI also depends on whether the food is eaten in isolation or with other foods. Consuming a food along with protein, fat, or other CHO that have a lower GI effectively lowers its GI value. Other factors that might affect a food’s GI include the ripeness of fruits (under-ripe fruits have a lower GI than ripe ones) and also how food is cooked or processed.”
