CHICAGO – The American Dietetic Association has appointed four registered dietitians to three-year terms as media spokespeople for the Association. ADA’s nationwide volunteer spokesperson network consists of 30 RDs who conduct more than 2,000 print, broadcast and electronic interviews each year on behalf of ADA on nutrition and healthful eating. As RDs, these spokespeople are the food and nutrition experts, having fulfilled specific requirements, including having earned at least a bachelor's degree (about half of RDs hold advanced degrees), completed a supervised practice program and passed a registration examination — in addition to maintaining continuing education requirements for recertification.

The following registered dietitians have been appointed as new ADA spokespeople for 2010-2013:

  • Karen Ansel, MS, RD, New York, N.Y.
    Ansel is a freelance journalist focusing on nutrition, food and health. Her areas of expertise include executive health, family nutrition and food preparation and meal planning.
  • Heather Mangieri, MS, RD, LDN, CSSD, Pittsburgh, Pa.
    Mangieri is the owner of a nutrition consulting practice and a faculty member in the exercise science department at Chatham University. Her areas of expertise include sports nutrition and fitness, disease prevention and fad diets.
  • Marjorie Nolan, MS, RD, LD, CPT, New York, N.Y.
    Nolan owns a private nutrition consulting practice and works as an outpatient dietitian for the Renfrew Center. Her areas of expertise include eating disorders, nutritional psychotherapy and behavior and lifestyle modification.
  • Manuel Villacorta, MS, RD, CSSD, San Francisco, Calif.
    Villacorta is the owner of a private practice nutrition clinic and creator of a weight management program. His areas of expertise include obesity and weight management, sports nutrition and fitness and worksite nutrition.

In addition, the following current ADA spokespeople have been reappointed for 2010-13:

  • Joan Salge Blake, MS, RD, LDN, Boston, Mass.
    Blake is a clinical assistant professor and director of the dietetic internship at the Sargent College of Health and Rehabilitation Sciences at Boston University. Her areas of expertise include cardiovascular nutrition, food safety and hypertension.

  • Christine Gerbstadt, MD, MPH, RD, LD, CSSD, Sarasota, Fla.
