Watermelon has also been touted as a possible aid for individuals with diabetes. But is this true? Let's explore the evidence.

Glycemic Index of Watermelon

The glycemic index is the rating given to foods based on how quickly that particular food raises blood sugar levels when eaten. 

The glycemic index of watermelon is 72, which is high4. Such foods with a glycemic index value ≥ 70 are strictly restricted from being included in the diet of individuals with diabetes.

Watermelon in Diabetes

So, is watermelon good for diabetic patients? 

According to a study, lycopene present in the flesh of the watermelon and ⍺-glucosidase present in the watermelon leaf extract has antidiabetic properties and could potentially be used for the treatment of diabetes5.

In another study conducted on 40 rats with diabetes, it was found that administration of different doses of watermelon juice reduced the fasting blood glucose level5.

However, it's important to note that these studies were conducted using watermelon flesh, leaf extract and in animals, respectively, so it's not clear if the same effects would be seen in all individuals with diabetes. 

Additionally, the results of these studies are preliminary and more research is needed to determine if a watermelon is truly effective for individuals with diabetes.

Also, considering the high glycemic index value of watermelon, it cannot be advised for diabetic people. 

Managing diabetes requires a combination of lifestyle changes, such as eating a healthy diet, getting regular exercise, and taking medications as prescribed.

Recipes of watermelon
