Oct. 27, 2013 -- intro:Frozen foods get a bad rap for being processed junk, but the truth is, some of the healthiest foods in the market are in the freezer section. Here are five important reasons to stock up today, and all year round, on iced veggies and fruits:

Because most frozen fruits and veggies are frozen shortly after they're harvested, they're allowed to fully ripen, which means they're chock full of vitamins, minerals, and antioxidants, and freezing "locks in" many of their nutrients. On the flip side, much of the fresh produce in your supermarket was reaped over 1,500 miles away, and had to travel by truck to get there. As a result, it may have been harvested before it reached its nutritional peak, then artificially ripened during transport.

How to Get Your Favorite Fruits in Winter

Scientists from Leatherhead Food Research and University of Chester, carried out 40 tests to measure nutrient levels in produce that had been sitting in a fridge for three days, compared to frozen equivalents. They found more beneficial nutrients overall in the frozen samples, in everything from broccoli to blueberries. In fact, in two out of three cases, frozen fruits and veggies packed higher levels of antioxidants, including polyphenols, anthocyanins, lutein, and beta-carotene. This conclusion supports previous research, which found that freezing produce does not destroy its nutrients. In one report, the vitamin C content in fresh broccoli plummet by more than 50% with a week, but dipped by just 10% over an entire year when frozen.

10 Forgotten Winter Fruits and Veggies

quicklist: 3 category:5 Reasons to Buy Frozen Fruits and Veggies title:They're additive-free url: text:Because freezing preserves food, no unwanted additives are needed in bags of frozen goodies, like spinach and strawberries. In addition, "naked" produce (e.g. no added salt or sugar) is the norm, so it's incredibly easy to find fruits and veggies with single word ingredient lists--simply the fruit or veggie itself. To be sure, always check the ingredients, but I bet you'll find at least a dozen varieties in the freezer aisle with absolutely nothing added.

One study found that working women spend, on average, less than one hour a day preparing, serving, eating, and cleaning up after meals. That's not under an hour for each meal – it's less than one hour for all daily meals! Because frozen produce is prep-free, reaching for it can save you a ton of time, allowing you to make healthy dishes at home, rather than opting for takeout.

quicklist: 5 category:5 Reasons to Buy Frozen Fruits and Veggies title:They're versatile url: text:I keep my freezer stocked with a spectrum of frozen fruits and veggies, and use them in a variety of ways. In addition to adding frozen fruit to smoothies, I thaw or warm it as a topping for oatmeal, or whole grain toast spread with almond butter. Frozen veggies are my chief ingredient in stir fry dishes, but I also love to sauté them in extra virgin olive oil with garlic and herbs, toss with a little quinoa or brown rice pasta, and top with a lean protein. For a quick and easy side dish, I keep jars of all natural, vegan pesto and tapenade, to toss with steamed frozen veggies. Some of my favorite combos are: broccoli with sundried tomato pesto; spinach with roasted red pepper pesto; and French cut green beans with green and black olive tapenade. Simple, delicious, and ready in a jiffy.
