Sugar content of a banana

The sugar content of a banana is relatively high, with more than half of its carbohydrates being fruit sugar. Its glycemic index falls within the medium range – 50-52 – but it is still advisable to consume it in moderation. Consuming one banana per day is sufficient, unless there is diabetes present. With this amount, the beneficial effects of the banana are already felt by the body.

The glycemic index is a value between 1 and 100 that indicates how quickly and how much a particular food raises blood sugar levels. Glucose, or commonly known as blood sugar, is derived from carbohydrates consumed during meals and serves as the most important energy source for the human body. It circulates in the blood and is delivered to cells located throughout the body.

Classification of carbohydrates

Carbohydrates can be categorized into two main groups:

  1. Simple carbohydrates (e.g., honey, fructose)
  2. Complex carbohydrates (grains, starchy vegetables, legumes)

Low glycemic index (GI) foods only cause a minimal increase in blood sugar levels, while high GI foods trigger a significant rise in glucose levels and result in an increased insulin response.
