What is glycemic index? 

Glycemic Index is a scale that gives you an idea about the number of carbohydrates in foods from 0-100. This number indicates how quickly the food causes an individual’s blood sugar to rise. The Glycemic index is used to facilitate better blood sugar management. Every meal you eat changes your blood sugar level and the glycemic index measures the effect of the food you eat has on your blood sugar levels. 

In simple words, it is a ranking system that shows you how fast a type of food can raise your blood sugar.

Glycemic index

The glycemic index affects your health and eating food with a high glycemic index may cause a lot of health conditions like diabetes, obesity and cardiovascular diseases. People with diabetes need to use the Glycemic index to plan their meals to manage blood sugar levels. 

The smaller the number of the glycemic index is, the less impact the food has on your blood sugar level. Here is a breakdown of the glycemic index proportions: 

  • Low Glycemic Index: 55 or less
  • Medium Glycemic Index: 56-69
  • High Glycemic Index: 70 or more

You can check the glycemic index on packaged foods by checking their labels. You can check the glycemic index for some common foods on the internet too!

Why is the Glycemic index important? 

Our body needs glucose according to its metabolic demands. The usual requirement is 200 gms per day. Our brain totally depends on oxygen and glucose.

A low level of blood glucose may make you feel lethargic and hungry. This is why the glycemic index is crucial as it may help you maintain blood sugar levels by giving you an idea of how a type of food can raise your blood sugar level. This helps you in the long term as well.

This may help you in: 

  • Lowering the risk of heart diseases

Factors affecting the Glycemic Index of a food 

Glycemic index

The Glycemic index of a type of food is determined by various factors. The contents, nutrients and several other factors may be responsible for influencing the glycemic index. Here are some factors that affect the glycemic index of food: 

Type of sugar content 

Sugar isn’t always high in glycemic index. It is a common myth that all types of sugars have a high Glycemic index. It should be noted that the glycemic index of fructose may range from as low as 23 and up to 105 for maltose. So, the glycemic index of food may depend on the type of sugar it contains. 

How do refined carbs fare? 

Processed foods are not healthy for your health as they contain a high glycemic index. Processing methods in the preparation of the food like grinding, rolling can raise the glycemic index making it an unhealthy option for those who have diabetes or heart diseases.

Nutrients are very important for our health and they can influence the glycemic index but in a good way! More protein and fat in a meal can slow digestion and help reduce the glycemic response to the meal. 


Starch is a carb and it includes two molecules- amylose and amylopectin. Foods that contain high amylose will have a much lower glycemic index than foods containing amylopectin as amylose is difficult to digest. 

Cooking method 

Usually, food that is cooked for a longer period of time will have a high glycemic response to it than food that is cooked for a shorter period. 


Ripeness may influence the glycemic index as an unripe fruit has less glycemic index than a riper fruit.
