Some vegetables start losing vitamins:

Fresh spinach is better for you than frozen.
True
False
Fresh spinach is better for you than frozen.
If they’re fully ripe and frozen or canned quickly after being picked, some fruits and veggies can be more nutritious than the fresh ones at the grocery store. For instance, frozen spinach has higher levels of many nutrients, including calcium and vitamin E. Not all canned or frozen fruits and vegetables offer better nutrition than they do when they are fresh. Neither frozen green peas nor canned peaches, for instance, have more vitamin C than the ones you get in the produce section of your grocery store. But taking time to compare the nutritional value of frozen or canned produce with what you get from fresh fruits and vegetables can help you find easier ways to provide the nutrients you want your family to get.

There’s no guarantee they’ll still taste good, though. And they won’t be as good for you as they might have been had you eaten them sooner. If you’re concerned about quality and nutrition, eat veggies stored in a standard freezer/fridge combination within 6 weeks. If they’re in a freezer chest, you can keep them up to 3 months.

You also can put them back in the freezer if the package still has ice crystals in it and still feels refrigerator-cold. Otherwise, it’s best to toss them.
You can keep that can of corn on the shelf:
Up to 1 year
Up to 2 years
2 to 5 years
You can keep that can of corn on the shelf:
Potatoes, carrots, spinach, beets, peas, and pumpkin should last that long, too. But don’t wait to use canned fruits and vegetables that are high in acid. Juices, tomatoes, grapefruit, pineapple, apples, peaches, pears, plums, berries, and pickles should be eaten within 12 to 18 months.
You shouldn’t buy cans that are:
Bulging
Dented
Both
You shouldn’t buy cans that are:

Some canned vegetables you buy at the grocery store may have lead in them.
True
False
Some canned vegetables you buy at the grocery store may have lead in them.
The U.S. made food companies stop using lead in cans in 1995. The FDA also prohibits the sale in America of foreign foods and products that have lead. Even so, some foods packed in cans with lead are sold in this country. Watch out for cans with wide silver-gray seams (where the body and lid overlap). Over time, the lead can leak into the food inside.

Aluminum foil
Glass jar
Wax paper

The wrong container can lead to freezer burn and make your fruits and veggies smell weird – and no one wants that. Put them in something that’s easy to seal, keeps out water and air, and will stand up to the extreme temperature of your freezer.
Make sure to get wide-mouth, dual-purpose glass jars made specifically for freezing and canning. Other good options are plastic freezer containers and freezer bags.
