A Guideline Daily Amount (GDA) was a nutrition facts label originally designed in 1996 in the United Kingdom (UK) as a collaboration between the government, the food industry and consumer organisations. GDAs appeared on the front and back of food packaging to help raise awareness of how much a food item represents as a proportion of a balanced intake each day in each food element (e.g. energy, fat, salt, etc.). The British initiative was followed in the European Union (EU) and influenced similar systems in other countries including the United States.
It is now replaced by Reference Intake (RI) in the UK and the EU.
