Acceptable Daily Intake (ADI)
The Acceptable Daily Intake (ADI) is a measure of the quantity of a particular chemical in food which, it is believed, can be consumed on a daily basis over a lifetime without harm. Data for the calculation of an ADI may be derived from a variety of sources; often direct observation of human eating habits is used, but laboratory tests may also be appropriate.
The concept of an ADI is most valuable when applied to chemicals which are not usually found in foods, such as additives or the residues of pesticides or veterinary drugs. ADIs may be defined both for humans and for animals, and are widely used by organisations such as the World Health Organisation.
See also Tolerable Daily Intake.
