Adjunct Associate Professor of Nutrition, Harvard University

P.K. Newby, ScD, MPH, MS (“The Nutrition Doctor”) is a scientist, gastronome, and author with twenty-five years’ experience researching diet-related diseases; studying how people make food choices and their impact on the environment; and teaching why what we eat matters, from farm to fork. She is a thought leader who speaks locally, nationally, and internationally, and her newest book is "Food and Nutrition: What Everyone Needs to Know" (Oxford University Press, 2018). Other works include "Superfoods" (National Geographic, 2016); two ebooks on employee health and wellness (Virgin Pulse, 2015); and "Foods for Health: Choose and Use the Very Best Foods for Your Family and Our Planet" (National Geographic, 2014). She also communicates with the public on her blog, "Cooking & Eating the PK Way". She consults regularly and has served as a science advisor to several companies. Dr. Newby's passion for nutrition stems from a life-long love affair with food, from cooking, baking, and gardening as a kid to working in the restaurant industry. She was one of the “best undiscovered cooks” on ABC’s "The Taste" (2014-2015) where she created globally inspired, plant-based cuisine based on her “Healthy Hedonism” philosophy—and she was the last woman standing with domestic goddess Nigella Lawson. She holds a doctorate from Harvard, two master’s degrees from Columbia, and served on the faculties at Tufts University (Research Scientist & Assistant Professor) and Boston University (Associate Professor). She’s currently an Adjunct Associate Professor and award-winning educator at Harvard and dedicates most of her time to fighting anti-science in all the ways that she can.
