Is Your Frozen Dinner Making You Fat?

We’re all guilty of it: microwaving a frozen dinner instead of preparing a fresh and nutritious meal after a long day. But have you ever wondered what’s really packed inside that frozen box? We went to Registered Dietitian Tanya Zuckerbrot to find out.

“Frozen meals can be loaded with calories, fat, preservatives and sodium,” she warns. But it’s not just the nutrition label she wants you to watch out for: “Beware of packing that looks like it has been kicked around, and boxes covered in frost. These are good indications that a meal has been left out for a prolonged period and then re-frozen or mishandled.” To get the most out of your frozen food, Zuckerbrot says to make sure “that any meal you choose has been handled properly throughout its journey to your table.”

Even if you have to stay away from the rumpled microwave boxes, there’s still hope for you die-hard defrosters: Frozen vegetables and fruits are one of the best choices you can make in the frozen food section. Actually, vegetables and fruits “may even be healthier than their fresh counterparts basking on the produce aisle!” Zuckerbrot tells us. “Researchers at the University of Illinois at Urbana-Champaign found that fresh green beans and spinach stored in the refrigerator for a week lost 75 percent of their vitamin C.” And, she adds, “Vegetables intended for the freezer case are flash frozen right as they are being harvested, so there’s a very good chance that what’s in your microwavable meal is still at its nutritional peak.”

But what if you want to eat more than green beans and spinach for dinner? Here’s a breakdown of some of the healthiest brands of frozen meals ... and Zuckerbrot’s personal favorites!
