All foods deteriorate as they age. This is a problem for the food industry because many foods are shipped over great distances. Therefore chemicals are added to preserve foods and give them a longer “shelf life”. Unfortunately, in spite of chemicals, the nutrient content of foods decline over time, even though they may look the same.
Even fresh fruits or vegetables may be sprayed, gassed or fumigated in order to make them look “ripe” and “fresh”. So what looks healthy isn’t necessarily as healthy as you may think.
