"With shipping and storage, fresh fruit can often sit around for as long as two weeks before it hits your supermarket," says Suzanne Henson, RD, director of the University of Alabama at Birmingham's EatRight Weight Management Program. "During that time, it can lose a lot of its nutrients, especially vitamin C."
In contrast, frozen fruit is often picked and frozen at the peak of freshness. It's also a better choice for concocting smoothies. But watch out for frozen fruits in syrup -- it packs extra calories.
