Remember when fruit was just fruit? Turns out, including watermelon in your daily diet could give your health a serious boost. Researchers looked into data spanning 15 years to see how this refreshing snack stacks up nutritionally.

Watermelon consumption was modest across the board — on average, children ate 7.51 gm per day, adults 7.29 gm. But for those who actually indulged, the numbers jumped to 125 gm daily for kids and 161 gm for adults. And it’s not just hydration, they saw real nutritional benefits.
