Jaclyn London

A registered dietitian with a Bachelor of Arts degree from Northwestern University and a Master of Science degree in Clinical Nutrition from New York University, Jaclyn “Jackie” London handles all of Good Housekeeping’s nutrition-related content, testing, and evaluation. Prior to joining Good Housekeeping, she was a clinical dietitian at Mount Sinai Hospital. In addition to reporting on nutrition news and trends, noteworthy products, “myth-busting” diet fads, weight-loss tips and eating advice, she oversees taste-tests and reviews all food products interested in earning the Good Housekeeping Seal or the GH Nutritionist Approved emblem. She loves establishing healthful nutritional criteria and evaluating packaged food claims (“low-sodium,” “high-fiber”) to make sure they’re legit. Jackie is a regular expert guest on The Dr. Oz Show and The Today Show. She is also an adjunct professor at Touro College and author of the upcoming book Dressing on the Side (and Other Diet Myths Debunked).
