Estimate of the amount of a substance in food and/or drinking water, expressed on a body weight basis that can be ingested daily over a lifetime without appreciable health risk to the consumer on the basis of all the known facts at the time of the evaluation.
It is usually expressed in milligrams of the chemical per kilogram of body weight. ADIs are used for substances that have a reason to be found in food (as opposed to a contaminant - see TDI) and as such, include additives, pesticide residues and veterinary drugs in foods. (Source: FAO WHO (1997) )

The suprarenal or adrenal glands, each perched over one of the kidneys, are
double glands. The core, or medulla, manufactures adrenalin, noradrenalin and a
small amount of dopamine. The outer layer of the gland is called the cortex. The
adrenal cortex produces three groups of corticosteroids; mineralocorticoids
(aldosterone) - control electrolyte and water balance, glucocorticoids
(cortisol)- influence carbohydrate
metabolism and sex steroid
hormones (androgens, DHEA).

An amino acid molecule has the general formula NH2CHRCOOH, where "R" is any one of a number of side groups. Amino acids are building blocks (small molecules that link together to form long chains) of proteins.
There are 20 amino acids found in proteins, called primary amino acids. Non-essential amino acids are those made by the human body, while essential amino acids are only obtained from protein in the foods that we eat. (Source: GreenFacts)

The amount of a substance to which a person is exposed over some time period.
Dose is a measurement of exposure. Dose is often expressed as milligram (amount)
per kilogram (a measure of body weight) per day (a measure of time) when people
eat or drink contaminated water, food, or soil. In general, the greater the
dose, the greater the likelihood of an effect. An "exposure dose" is how much of
a substance is encountered in the environment. An "absorbed dose" is the amount
of a substance that actually got into the body through the eyes, skin, stomach,
intestines, or lungs.

The Scientific Committee on Food (SCF) is one of the Committees providing the European Commission with scientific advice on food safety. This Committee, composed of independent scientists, was established in November 1974, and transferred to the European Food Safety Authority (EFSA) in May 2003.
The SCF is mandated to address "scientific and technical questions concerning consumer health and food safety associated with the consumption of food products and in particular questions relating to toxicology and hygiene in the entire food production chain, nutrition, and applications of agrifood technologies, as well as those relating to materials coming into contact with foodstuffs, such as packaging."

The founding regulation of EEA stipulates that it is open to countries that do not belong to the European Union but share its concern for the environment.

"The European Food Information Council, EUFIC, is a non-profit organisation which provides science-based information on food and food-related topics to the media, health and nutrition professionals, educators, and opinion leaders."
"EUFIC acts as a vital link in the communication chain by channeling information gathered at the source - primarily from nutrition and food safety experts - through to the consumers.
EUFIC's mission is directly related to the increasing public demand for sound, balanced information on the nutritional quality and safety of foods.
EUFIC directs its resources towards three broad areas:
Contact of the cells of an organism with a substance, micro-organism or radiation. In the case of humans, this may involve contact with a substance or agent by swallowing, breathing, or through the skin or eyes. Exposure may be short-term [acute exposure], of intermediate duration, or long-term [chronic exposure].
Exposure can be divided into external and internal.
External exposure refers to the whole dose to which an organism is exposed.
Internal exposure refers only to that fraction of the initial chemical dose that is absorbed and distributed throughout the body via systemic circulation. (Source: GreenFacts)

pH is a measure of the concentration of protons (H+) in a solution and, therefore, its acidity or alkalinity. The concept was introduced by S.P.L. Sørensen in 1909. The p stands for the German "Potenz", meaning power or concentration, and the H for the hydrogen ion (H+). In layman's terms , the "pH" value is an approximate number between 0 and 14 that indicates whether a solution is acidic (pH < 7), basic (pH > 7) or neither (pH = 7) [neutral]. (Source: GreenFacts )
