Why they're safe: Avocados' thick skin keeps out insects that might feast on them—and whatever pesticides are used. "Any residues on there would be removed through the peel," Benbrook says.
Why they're healthy: Avocados are loaded with folate, which helps with the rapid cell growth that occurs during pregnancy and infancy, and with monounsaturated fats, the kind that promote HDL or "good" cholesterol, Rodriguez says. They deserve props for their fiber content, too: One avocado contains almost 14 grams of fiber, compared to just 4 in an apple, Blatner says. "Avocados are soft, smooth and pleasing to the palate—and a source of fiber that people don't think about," Rodriguez says.
