Canned vegetables: how healthy are canned vegetables?

How healthy are canned vegetables?

Most of you will know it: When time is short and hunger is great, many reach for vegetables or fruits from the can. The food is already peeled and cut and can be processed straight away. Since canned food can usually be kept for years, canned peas, carrots, corn and the like are always at home. But can something that lasts so long be healthy? What about the vitamin content? Do they break when you heat up the canned food?

The fact is: canned vegetables are usually processed immediately after harvest and briefly blanched. Thanks to this gentle process, the vitamins are largely retained. Protection from light also helps ensure that the vitamins are retained. The fat-soluble vitamin content of most canned vegetables is usually not that different from that of fresh vegetables. The amount of vitamin loss depends on the duration of the pasteurization. The longer the heating time, the greater the loss of vitamins. This primarily affects water-soluble, heat-sensitive vitamins such as vitamin C and the B vitamins: Here, losses of 40 to 65 percent of the vitamin content are possible if the vegetables are heated for too long. That is why you should also be careful not to let vegetables simmer for too long when cooking.

Canned vegetables: heating time affects vitamin content

Usually only water, a little salt or sugar is added to the vegetables. The latter have a preservative effect and prevent the vegetables from spoiling. The pasteurization, i.e. brief heating to 60 to 90 degrees, kills germs.

When cooking, it doesn't make much difference whether you use fresh vegetables or canned vegetables, as vitamins are lost during cooking anyway. In winter, in particular, it pays to use canned vegetables. This is often a healthier alternative to fresh vegetables from countries such as Spain, Portugal or overseas. To ensure that the latter survives the long transport to Germany unscathed, pesticides are often used. Therefore, you should prefer canned fruits and vegetables to imported ones. Ultimately, it's best to buy the fruit and vegetables that are currently in season. Fresh, local fruit and vegetables are and always will be the healthiest.
