Where does watermelon fall on the glycemic index?
The glycemic index (GI) looks at how fast food sugar enters the blood stream. Each food item is given a value between 1 and 100. These values are determined according to how each food compares to a reference item. Sugar or white bread is generally used for reference.
Glycemic load (GL) is the combination of the GI and the actual carbohydrate content in a typical serving of food. It’s argued that the GL gives a more real-world value of how a specific food can affect blood sugar levels.
People who are managing their diabetes by carbohydrate counting often use this approach. Foods with a low or medium GI are considered less likely to raise your blood sugar levels.
A GI of 55 or less is considered to be low. A GI between 55 and 69 is generally considered to be medium. Anything over 70 is considered to be high.
A GL under 10 is low, 10 to 19 is medium, and 19 and above is considered high.
Watermelon typically has a GI of 72 but a GL of 2 per 100 gram serving. The GL of watermelon is low, and it can be eaten in moderation like all fruit as part of a balanced meal.
