They have mainly three functions: cosmetic, processing aids and preservatives. It is assumed that there are about 3794 types of additives out of which 90% have only cosmetic value. More than three-fourth of the western foods comprises of processed foods.

Till the last decade, the use of additives was no so extensive. There is nothing natural about the additives and they are synthetic. When the additives enter the body, the body treats them as foreign bodies and start resisting them. This causes different food allergies or irritant in the body.
