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; with Barton Seaver). 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 and on the boards of 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.

About Nutrition Scientist & Food Expert Dr. P.K. Newby

Health Expert: Food and Nutrition, Farm to Fork

As a nutrition scientist and health expert, I spent the first 20+ years of my career researching diet, obesity, and chronic diseases; studying how people eat; and talking about why what we eat matters, from farm to fork. Today, I focus my time on science communication to reach everyday eaters far beyond the university through books, television, and all the ways I can. I also do a wide range of consulting and speaking around the world.

Food Personality: Healthy Hedonism

PK Newby, food personality consultant Science makes the world go ’round—but art makes the ride more enjoyable. My creative pursuits span the culinary and performing arts, kitchen to stage. We had a huge garden in my backyard when I was a kid, and I developed cooking and baking skills at my mother’s side. I started working in an Irish pub as a teenager and gained an appreciation for fine dining after a decade in the business. I’ve worked for many excellent restaurants and caterers and held a job as one of the main cooks in a small vegetarian café while in college. I’ve spent my life cooking and entertaining, from intimate dinner parties with wine-paired courses to lavish cocktail parties with signature cocktails. Whatever’s on the menu, my dishes feature global flavors and spices and make plants the star of the plate; that’s the #pkway.

After spending many years performing onstage—not professionally, though when I was a little girl I dreamt of being a Broadway star—I founded a Boston-based community theatre company, The Longwood Players. I began this organization when I was a student at Harvard, and it grew into one of Boston’s preeminent nonprofit theater companies, now in its twenty-third season. (I’m now President Emeritus and Founder.) I made my primetime debut on ABC’s The Taste as one of America’s “best undiscovered cooks” alongside Domestic Goddess Nigella Lawson.

P.K. at Play


Meditation is part of my daily life and I’ve been practicing yoga regularly for 11 years for health and wellbeing. Participating in a yoga retreat is a sublime gift I give myself every now and again, and I’ve done so in Massachusetts (Berkshires and Martha’s Vineyard), New York, and Thailand; India is next on my list.

I keep my endorphins up and my weight down by staying active. I was even a certified fitness instructor while a struggling grad student to help me pay the bills while getting free gym memberships! Today, my main fitness endeavors are walking, yoga, Pilates, and running. I ran the Boston Marathon in 2010 and 2013. Other marathons include Portland, ME, in 2011 (3:42:30, my personal record and a Boston qualifier); Las Vegas, NV in 2014; Chicago, IL in 2015; Niagara, CAN in 2017; and Toronto, CAN in 2018. Up next: Boston again, 2020. (I’ve also got a bunch of half-marathons and 10Ks in there too, like most runners.) Be warned: Marathons are addictive (in a mostly healthy way).



Other passions of mine include traveling, reading, and music, as well as spending time with my husband, friends, family, and dog. (Her name is K’Ehleyr (a geeky Star Trek reference); she brings immense joy into our lives.) I also spend a lot of time shopping at local farmers markets around Boston and Cambridge, a big theme on my blog. I’ve been to many cities and towns throughout the US, and countries I’ve visited thus far include: Australia, Bahamas, Brazil, Camobodia, Canada, Czechia, Denmark, England, Finland, France, Greece, Hungary, Iceland, India, Ireland, Italy, Mexico, Netherlands, Norway, St. Martin, Scotland, Sweden, Spain, Singapore, Switzerland, Thailand, and Turkey. I was born in Canada; live in the United States; and I dream about traveling to space.
