Watermelon Glycemic Index

Watermelons have high carbohydrates and natural sugars, but the way your body breaks them down determines whether they cause glucose spikes or not. Glycemic index and glycemic load are essential to understand these.

Watermelon has a Glycemic index of 72 and a glycemic load of 2 per 100g serving. What does this mean? Let us understand glycemic index and glycemic load.

The Glycemic index depicts how quickly our body absorbs sugar from food. Based on how fast our stomach digests the food and releases it into the bloodstream, GI is calculated. It ranges from a scale of 0 to 100. Foods on the scale 0 to 55 are low GI, 55 to 70 are medium GI, and above 70 are high GI. 

Dieticians argue glycemic load is a better indicator. It is a combination of GI with actual carbohydrate content in a food serving. 0-10 is low GL, 10-19 is medium GL, and anything value above 19 is high.

Watermelon has a low glycemic load of 2 per 100g serving. Though the GI of watermelon is high, its low GL indicates watermelon can be consumed in moderation by people with diabetes.

Glycemic load of watermelon

A food's glycemic load (GL) accounts for both the amount of carbs it contains and how they affect blood sugar levels. Since watermelon has a relatively low GL, moderate consumption is unlikely to result in significant blood sugar spikes. A cup (or 152 grammes) of diced watermelon is thought to have a low glycemic load of roughly 5, which is 5. This is because watermelon has a low carbohydrate content compared to other fruits and contains fibre and water, both of which can reduce the blood sugar absorption.
