Fresh vs Frozen Produce: Are we giving up nutrition for convenience?
Most people typically eat only one-third of the recommended
daily intake (three servings instead of nine) of fruits and vegetables, so if
you’re confused as to which to choose, vegetables or fruits in any form is
better than none at all.
Fruits and vegetables are mostly found in 3 ways at your
grocery store:
- Fresh
- Canned
- Frozen
The nutritional content varies according to the type of
fruits or vegetables you get.
Canned vegetables tend to lose a lot of nutrients during the
preservation process (notable exceptions include tomatoes and pumpkin). Canned
fruits and vegetables tend to be higher in sugar and salt content. When
choosing canned vegetables, choose low-sodium or no added sodium options. When
choosing canned fruit make sure you buy fruit in fruit juice and not fruit in
syrup.
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. Frozen vegetables may be even more healthful than some of the fresh
produce sold in supermarkets. Fruits and vegetables chosen for freezing tend to
be processed at their peak ripeness, a time when—as a general rule—they are
most nutrient-packed.
While the first step of freezing fruits or vegetables—blanching
them in hot water or steam to kill bacteria and arrest the action of
food-degrading enzymes—causes some water-soluble nutrients like vitamin C and
the B vitamins to break down or leach out, the subsequent flash-freeze locks
the vegetables/fruits in a relatively nutrient-rich state.
Freezing preserves food, so 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.
On the other hand, fruits and vegetables destined to be
shipped to the fresh-produce aisles around the country typically are picked
before they are ripe, which gives them less time to develop a full spectrum of
vitamins and minerals. Outward signs of ripening may still occur, but these
vegetables will never have the same nutritive value as if they had been allowed
to fully ripen on the vine. In addition, during the long haul from farm to
fork, fresh fruits and vegetables are exposed to lots of heat and light, which
degrade some nutrients, especially delicate vitamins like C and the B vitamin
thiamin.
Bottom Line:
- When vegetables are in-season, buy them fresh and ripe. “Off-season,” frozen vegetables will give you a high concentration of nutrients.
- The nutritional content of frozen and fresh produce is very similar, maybe better in frozen foods. So when in dilemma you can choose whatever option is available.
- Choose frozen or fresh fruits and vegetables over canned
- Frozen vegetables and fruits are usually cut, washed and prepped so it makes them a very easy way to add them to our meals. Helping us to increase their intake.
- Frozen vegetables tend to be a cheaper option than fresh produce
- Eat them soon after purchase: over many months, nutrients in frozen vegetables do inevitably degrade.
- Finally, steam or microwave rather than boil your produce to minimize the loss of water-soluble vitamins.
I always wondered if i should buy frozen vegetables or not. This helps....
