20. Canned Soup
Canned soup is known to be very convenient and very cheap. You can get a can of soup for less than a dollar, and then all you need to do is add water (sometimes) and cook! However, the fact that these products are processed and canned in a manner that helps them gain a lengthy shelf-life means that all the nutritional and the health benefits of the products are as good as depleted. Hence, they do not really offer you any health related benefits. On the contrary, they cause a great deal of harm to your health as a single can of soup has enough sodium to increase the levels of your blood pressure drastically.
