The idea of organizing the nutritional scientists of Asia into a federation was explored during the First Asian Congress of Nutrition held in Hyderabad, India, in 1971. FANS was formally organized during the Second Asian Congress held in Manila in 1973. Fourteen countries were the original signatories to the formation of the FANS, namely, Afghanistan, Bangladesh, India, Indonesia, Iran, Japan, Korea, Lebanon, Nepal, New Guinea, Pakistan, Philippines, Sri Lanka and Thailand.
FANS is envisaged to have a simple organization – practical and realistic to cope with the Asian situation of development. It should hold regular Congresses and meetings and open communications between members in the region.
