Glycemic Index of Banana

The glycemic index (GI) of a banana can vary depending on factors such as ripeness, variety, and size. Generally, the riper the banana, the higher its GI.

On average, a medium-sized banana with a GI of around 48 is considered to have a low glycemic index. However, the GI of a ripe banana can be higher, reaching up to 85, which is considered high on the glycemic index scale.

It’s important to note that the glycemic index of a food is not the only factor to consider when it comes to managing blood sugar levels. The glycemic load (GL) of a food takes into account both the GI and the serving size, providing a more accurate picture of how a food will affect blood sugar levels.

Glycemic Load of Banana

The glycemic load per 100 grams of a banana is around 10.1, which is considered moderate. However, while bananas may have a moderate to high glycemic index, they still provide a relatively low glycemic load per serving (80 grams). Additionally, bananas are a good source of fiber, vitamins, and minerals, making them a healthy and nutritious food choice for most people.
