Why Canned Produce Has Just as Many Nutrients as Fresh Produce

Why Canned Produce Has Just as Many Nutrients as Fresh Produce

Canned fruits and vegetables have a reputation for not being as packed with nutrients as their fresh counterparts, but as The New York Times points out, by the time that produce actually reaches you, both canned and fresh are on pretty equal footing.

In fact, canned fruits and vegetables sometimes retain more of their nutrients than fresh produce. While freshly picked fruits and vegetables start with more vitamins, by the time they're shipped, packed, and end up in your shopping basket they've lost some of their luster:

Canned produce can lose some of its nutritional value as well, particularly water-soluble nutrients like vitamins B and C. But over all, the nutrients in canned fruits and vegetables tend to be relatively stable because they are protected from the deteriorating effects of oxygen, a fact emphasized in an extensive report on the subject published in The Journal of the Science of Food and Agriculture by researchers at the University of California, Davis.

“Fresh fruits and vegetables usually lose nutrients more rapidly than canned or frozen products,” the researchers wrote. “Losses of nutrients during fresh storage may be more substantial than consumers realize” and may not be reflected on nutrition labels.

Of course, both fresh produce and canned produce are still healthy, and either option is better than nothing.

I did not have all of this at home when I started the project. But when I knew how I wanted the speaker to become I started buying parts.
