Not all organic produce is created equal.
For example, don't waste money on organic fruits and vegetables with tough or inedible peels such as pineapples, papayas, mangos and avocados. "Most of the pesticides can be removed or washed away," Woroch says, citing WebMd research.
If you do opt for organic, make sure you're getting the real thing. Look for the organic seal certified by the USDA, which confirms the food is grown, harvested, and processed according to federal standards.
Labels that boast "natural," "hormone-free" or "antibiotic-free" don't necessarily assure that food meets organic standards.
And when it comes to seafood, the U.S. has no organic fish regulations, so "don't waste your money on false food claims," Woroch says.
