Watermelon

 

Watermelon

Watermelon is a heavyweight in the nutrient department. A standard serving (about 2 cups) has one-third of a day’s vitamins A and C, a nice shot of potassium, and a healthy dose of lycopene for only 80 fat-free, salt-free calories. And when they’re in season, watermelons are often locally grown, which means they may have a smaller carbon footprint than some other fruits.
