General function claims under Article 13.1 of Regulation (EC) No. 1924/2006 refer to the role of a nutrient or substance in growth, development and body functions; psychological and behavioral functions; slimming and weight control, satiety or reduction of available energy from the diet.

In October 2009, EFSA published the highly controversial series of opinions which provided scientific evaluations for more than 500 “general function” health claims from a list of 4,185 claims submitted to EFSA. Now, a briefing document describes how EFSA has followed consistent procedures for evaluation of Article 13.1 health claims, including the use of uniform scientific criteria for substantiation of claims and for the characterization of foods.
