The working group "Questions of Nutrition" was founded on the initiative of Dr Hans Lange (Honorary Chairman of the Food Chemistry Society). The inaugural meeting took place in Frankfurt on 21 February 1974.

The working group prepares statements on current topics in the field of nutrition, on drafts of national and international legislative proposals or on specific scientific and food law enquiries. External experts can be consulted for advice on a case-by-case basis.

Members are food chemists and nutritionists from food monitoring organisations, universities and other research institutions, as well as from independent commercial laboratories and the food industry. The working group currently has a total of 18 active and 22 corresponding members.
