Welcome...

 

The role of nutrition in health promotion and disease prevention and treatment is becoming more evident and visible as the science of nutrition evolves and as health care reform becomes increasingly based on prevention and disease.  Consequently, there is an increasing demand for experts with specialized knowledge in nutrition and clinical nutrition on the part of educators, health professionals, the media, and consumers. 

American Society for Nutrition (ASN) members total over 3,000, with many nutrition practice specialties and sub-fields represented. ASN is the premier research society dedicated to improving the quality of life through the science of nutrition. ASN is committed to bringing together the world's top nutrition medical practitioners, researchers, policy makers and industry leaders to advance our knowledge and application of nutrition for the sake of humans and animals. Their members' practices range from the most critical details of research to the broadest applications in society
