Glycemic Index of Banana and its Impact On Diabetes

Glycemic Index of Banana are everyone’s delight. They are sweet-smelling, tasty, and considered nutritious. But about eating it during diabetes?

As a diabetic, you must have pondered over the sweetness of the banana. What is the glycemic of banana? Any guesses?

This article deals with a glycemic index score of banana and it impacts on diabetes. Let’s see if this nutritious fruit bestows the same health benefits upon diabetics or not.

What is the glycemic index?

Calculations and measurements are a part of the day to day life. We measure, compare, analyze certain numeric values every day. Be it a person on diet measuring his/her weight loss or doctor measuring the temperature of a patient suffering from fever.

How does the doctor confirm if the patient is suffering from a fever? And if the fever is moderate or critically high?

Because we already have standards set for measuring temperature using a thermometer. When the mercury levels cross 100 degree Celsius, an individual is supposed to be suffering from fever.

Similarly, the glycemic index is the measurement standard or formula made for calculating how quickly or slowly will the given food releases sugars in the bloodstream after it is eaten.

Ever seen a pH scale? The neutral elements are assigned a value of 7. Substances ranging in value less than 7 are considered acidic and those more than 7 are considered basic.

Following the same fashion, in the case of the glycemic index score, the reference value is chosen as 59-69. Foods having a score lesser than 59 are considered lower GI foods whereas those having a score of more than 69 are considered high GI foods.

The foods whose GI scores fall in the range of 59-69 are considered moderate GI foods. These can either harm you or can be harmless, depending upon your blood sugar levels and the number of calories permissible for you.

Low GI foods are good for diabetes. They slow down the rate of release of sugars from the food into your body. When this is done, blood sugar levels don’t rise after meals.
