ETYM Latin additivus.

In food, any natural or artificial chemical added to prolong the shelf life of processed foods (salt or nitrates), alter the color or flavor of food, or improve its food value (vitamins or minerals). Many chemical additives are used and they are subject to regulation, since individuals may be affected by constant exposure even to traces of certain additives and may suffer side effects ranging from headaches and hyperactivity to cancer. Food companies in many countries are now required by law to list additives used in their products. Within the European Union, approved additives are given an official E number.
They must be listed on labels of foods sold in the US so consumers may be aware of those they cannot tolerate. The natural food movement has grown enormously in the 1970s and 1980s, as increasing awareness of the dangers of additives sent consumers looking for additive-free foods.
