Life and career
editMarilyn Martha Horecker was born in Washington, D.C. on June 4, 1944, the daughter of Bernard and Frances (née Goldstein) Horecker. Her father was a biochemist and served as dean of the Weill Cornell Graduate School of Medical Sciences.[1] She grew up in Maryland and New York, and graduated from New York University in 1968, where she studied the Romance languages.[1]
In 1985,[2] with her then husband Harvey Diamond, she co-authored the best-selling health and wellness book Fit for Life.[3] The book built on the natural health movement that had roots in 19th century, and was part of the development of the fascination with celebrity beauty in contemporary American culture.[4]
Diamond's ideas about diet and aging have been the subject of controversy in the media.[5][6][7] In particular, nutritionists disagree with her assertion that some foods should not be eaten together.[8]
