The full form of TDI in medical term is “Tolerable Daily Intake.”
Tolerable Daily Intake (TDI) is a term used in toxicology to describe the maximum amount of a chemical or substance that a person can consume daily without significant risk of adverse health effects over a lifetime. TDI is an important concept in food safety, as it is used to establish acceptable levels of exposure to contaminants and additives in food.
The TDI is based on scientific data and is established by international organizations such as the World Health Organization (WHO) and the Food and Agriculture Organization (FAO) of the United Nations. These organizations evaluate the available data on the toxicity of a substance, including its effects on various organs and systems in the body, to determine the level of exposure that is safe for human consumption.
The TDI is calculated using a safety factor approach, which considers the variability of human sensitivity to a substance and any uncertainties in the data. The TDI establishes maximum levels of contaminants and additives in food. The TDI also establishes acceptable daily intakes (ADIs) for food additives. ADIs are the maximum amount of a food additive that can be safely consumed daily over a lifetime.
TDI is established by international organizations based on scientific data and is calculated using a safety factor approach to account for individual variability and uncertainties in the data. By establishing safe levels of exposure, the TDI helps to protect consumers from the adverse health effects of excessive exposure to harmful substances in food.
