In 2004, IGD embarked on a programme of work to take forward the further development of GDAs. A Technical Working Group on Guideline Daily Amounts was established to review existing IGD GDAs and to consider extending them and develop, where appropriate and agreed, new GDAs which could be used in a consistent way across industry, government and other organisations in the UK.

In developing GDAs, the process undertaken by the Working Group included reviewing national and international scientific evidence on current dietary recommendations, with a focus on UK requirements. It also included seeking the counsel of experts in the nutrients and age groups of concern.

The decisions of the Working Group and their rationale are detailed in this free report. (60 pages)
