Diabetes is one of the most commonly seen lifestyle diseases throughout the world. Millions of people are affected by it. Adherence to a healthy, balanced diet and healthy lifestyle is crucial to preventing and managing diabetes. People suffering from it should monitor the glycemic index of everything they eat. The glycemic index is the ranking of carbohydrate rich foods in the diet according to how they affect blood sugar levels. The higher the ranking, the higher the effect on blood sugar levels. Most people who have diabetes do not consume anything sweet or extra sugar.

Some fruits have a low glycemic index. Diabetic patients can eat such fruits in moderation. Choosing them can be a bit daunting. Below we will discuss the most common fruits that people with diabetes can include in limited amounts in their diet.

Why are Fruits Beneficial During Diabetes?

The notion that fruits are not safe for patients with diabetes is entirely wrong. Fruits are rich in a wide variety of vitamins, minerals and fibre. These are excellent for controlling blood sugar levels and reducing the risk of developing type 2 diabetes. The fibre content in fruits can also help prevent unhealthy cravings and overeating by making the stomach feel full. So they also play a vital role in healthy weight management, increasing your insulin sensitivity, thus helping with managing diabetes. 

What is the Glycemic Index?

The glycemic index is a statistic that measures how much a food that contains carbohydrates raises blood glucose levels. People with diabetes mainly follow the glycemic guide to choose the right foods. Foods with a high glycemic index value tend to raise your blood sugar levels more than foods with a low GI value. Foods with a value of 55 or less are considered low glycemic index foods, those with a value for 56 to 69 are considered medium glycemic index foods and those with a value above 70 are considered high glycemic index foods. A person with diabetes should consume fruits with low to medium glycemic index. Of these, however, low-GI fruits are most preferred. In addition, water-based fruits are beneficial for people with diabetes.
