Are canned food healthy? 10 facts 🙌

1.Canning is a method of packing food in air tight containers to last longer period of time. It can last from 1-5 years depending upon the kind of food preserved. 3 steps which include canning are processing the food by cleaning, peeling and slicing. Next step is packing them in air tight containers and lastly, heating or thermal sterilization of those containers to kill harmful bacteria and germs.

While canned food and vegetables are fine as long as it is not used daily. Canning restores nutrients and is easy and handy to use. They can be kept in the freezer for days when the availability of fresh produce is low.

3.Some studies show that canning restores the high nutrients of the food. Since canning involves heating, heat releases more antioxidants from food like tomatoes and corn. So, certain nutrient levels like antioxidants are increased. However, some water-soluble vitamins like C and B can get damaged due to the heating process.

4.Commercial canning and food packaging involves a chemical named BPA (bisphenol-A). Studies do show that the BPA in cans do get mixed with the food that has been preserved. Certain studies show that BPA can be linked to heart disease and type 2 diabetes. But, more studies are required to prove the hypothesis. Sometimes, bad and unhygienic canning can lead to contamination by harmful bacteria like botulism. So, it is important to avoid canned food which is damaged, leaked or cracked.
