American Society For Nutrition



Excellence in Nutrition Research and Practice


The American Society for Nutrition became the US Adhering Body to the International Union of Nutritional Sciences in 2008. However, our organizations have collaborated closely for many decades.

At ASN's annual meeting in 1949, President E.M. Nelson reported on a meeting he had attended in London in June of 1948. The meeting had been convened to consider the formation of an International Union of Nutrition Sciences (IUNS). At this meeting, a tentative constitution and by-laws for the proposed union was prepared and adopted. Application to the International Congress of Scientific Unions was made and acted on in September of 1949.

The IUNS mission is:
-To promote advancement in nutrition science, research and development through international cooperation at the global level.
-To encourage communication and collaboration among nutrition scientists as well as to disseminate information in nutritional sciences through modern communication technology.


IUNS Newsletter September 2016

The IUNS Newsletter September 2016 edition is now available to read online or to download in pdf form.

This edition includes updates on the revised IUNS Statutes and Rules and the latest news from the preparations of 21st IUNS-ICN in Buenos-Aires, Argentina.

International Congress of Nutrition

IUNS has organized International Congresses of Nutrition since 1952. In 1981, the ASN (then known as AIN) administered the International Congress in San Diego, CA (program chair: James Dinning). View the ASN Living Legends featured at the International Congress in 2009 in Bangkok, Thailand.

ASN maintains a competitive travel awards program for outstanding early-career and student investigators currently based in the U.S. The travel awards assist with costs related to attendance at the International Congresses. Funders are asked to provide grants of $3,500. Email us for more information.

2017 Congress

Dear Colleagues and Friends,

I feel honored to have the responsibility to chair the IUNS 21st International Congress of Nutrition (ICN), to be held in Buenos Aires, October 15th – 20th, 2017.

The Sociedad Argentina de Nutrición (SAN) will be in charge of managing the Congress. This renowned society was founded in 1941 by the scientist Prof. Pedro Escudero, pioneer in Latin America.

For ten years the SAN has been working together with Nutrition Societies of the Southern Cone, Brazil, Bolivia, Uruguay and Chile in the field of Nutrition Quality Education in medical schools, as well as joint activities with other scientific related societies.

The IUNS-ICN International Congress of Nutrition is a four yearly meeting that's been held since 1946. Its 21st edition will be based in Buenos Aires for the first time in its history.

It is my pleasure to invite you to experience this vibrant multicultural metropolis designated “City of Design” by UNESCO. Its wide range of cultural diversity will amaze you.

We are currently designing the scientific programme according to the motto “From Sciences to Nutrition Security” with the aim of encouraging the exchange of knowledge in order to achieve the improvement of Nutrition Security.

We intend to focus on every aspect of nutrition issues going through a wide variety of topics which will be dealt with from different perspectives in order to enrich our attendees' points of view.

Allow me to mention the pillars of our preliminary programme:

  1. Advances in Nutrition Research
  2. Nutrition Through Life Course
  3. Public Health Nutrition and Environment
  4. Nutrition and Management of Diseases
  5. Nutrients and Nutritional Assessment
  6. Functional Foods and Bioactive Compounds
  7. Food culture practices and Nutritional Education
  8. Agriculture, Food Science and Safety

Our main goal is to offer you a high-level meeting focused on addressing the key aspects of nutrition in a multicultural environment, from state-of-the-art reviews to cutting edge nutritional science information.

We hope to cover all your needs in 2017 and we are looking forward to giving you the warmest welcome.

See you soon in Buenos Aires!

Dr. Mabel Alicia Brígida Carrera
President of the IUNS 21st International Congress of Nutrition (ICN)

2013 Congress

IUNS held the 20th International Congress of Nutrition in Granada, Spain, Sept. 15-20, 2013. The theme for 2013 was "Joining Cultures Through Nutrition." ASN greeted many members and Congress attendees at Exhibit #101. Invited papers were published as a supplement in Advances in Nutrition and can be accessed through the Proceedings of the International Union of Nutritional Sciences (IUNS) 20th International Congress of Nutrition (ICN) collection.  

The E.V. McCollum Lecture, organized by ASN, took place on Tuesday, September 17 at 10:30 a.m. in the Lorca Auditorium. The keynote address was delivered by Lindsay H. Allen, PhD, RD, the Director of the USDA ARS Western Human Nutrition Research Center (WHNRC). Dr. Allen's research is focused on the prevalence, causes, consequences and prevention of micronutrient deficiencies including iron, vitamin B-12, zinc, vitamin A and riboflavin. As the 2012-2013 McCollum Lecturer, Dr. Allen presented a talk focused on “Micronutrient Research, Programs and Policy: From Meta-analyses to Metabolomics.”

Congratulations to the following travel award recipients, who received ASN support to attend the Congress in 2013. ASN remains appreciative of the organizations supporting student and emerging investigator travel to the ICN: the Office of Dietary Supplements at the National Institutes of Health; DuPont Nutrition & Health and Solae, LLC; and the Future Congresses Fund.
