Ask Tufts Experts July 2013 Issue

Q. In purchasing frozen fruits and vegetables, does it matter how far the produce traveled to my grocery store? Is frozen produce from Mexico, Chile or the Ukraine as nutritious as that from the US?

A. Alice H. Lichtenstein, DSc, Gershoff Professorof Nutrition Science and Policy at Tufts’ Friedman School, answers, “To my knowledge there are no data available on this topic. However, freeze/thawing cycles significantly decrease the quality of the product. Hence, it is in the producers’ and purveyors’ interest to maintain high quality, and thus to avoid temperature changes. The bottom line is that properly stored frozen fruits from other countries should be fine.”
