Watermelon is often celebrated as a summer staple — sweet, juicy, and packed with hydration. It’s also rich in essential nutrients like vitamins A and C, antioxidants, and electrolytes. But while this refreshing fruit offers many health benefits, it may not be suitable for everyone.
Here are five groups of people who may need to approach watermelon with a bit more caution:
1. Individuals with Diabetes
While watermelon is naturally low in calories and fat, it does have a high glycemic index (GI). This means it can cause a rapid increase in blood sugar levels. For those managing diabetes or insulin resistance, consuming high-GI foods in large amounts may make blood sugar control more challenging.

This can lead to a condition called hyperkalemia, which may cause muscle weakness, fatigue, or even heart rhythm issues.
