I am a Harvard-trained scientist and health expert with more than twenty years of experience researching diet, obesity, and chronic diseases; studying how people eat; and teaching students about why what we eat matters, farm to fork. Yet my passion for nutrition stems from a life-long love affair with food and cooking. I spent ten years working in the restaurant industry, two of which cooking in a vegetarian café. I made my prime time television debut on ABC's "The Taste" as one of America’s “best undiscovered cooks;” I was the last woman standing on Nigella Lawson's team. I still do some research and teaching at the university, but I spend most of my time today working with individuals and companies to help build a better world. . My obsession with science and food is at the heart of everything I do, from writing to consulting, speaking to media. I dream of having my own show one day, a fresh food personality for a new millennium, doing for globally inspired, plant based cuisine what Julia Child did for French fare. And I’m currently working on my next three books to help people live healthier lives, deliciously.

Health Expert: Communicating All Things Food and Nutrition, Farm to Fork

I’ve spent most of my professional life in the Ivory Tower as both student and researcher and am still an Adjunct Associate Professor at Harvard. I earned my doctoral degree in nutrition (ScD) at Harvard School of Public Health and completed master’s degrees in public health (MPH) and human nutrition (MS) from Columbia University. My bachelor’s degree (BS) in social welfare is from the State University of New York at Albany, with minors in psychology and sociology.

As a nutrition scientist and health expert, I spend most of my time researching diet, obesity, and chronic diseases; studying how people eat; and educating students and the public about a wide range of contemporary food issues. Weaving together traditional nutrition science, behavioral science, and environmental science, I teach using a nutrition ecology paradigm highlighting key topics in food production and public health “from farm to fork,” the subject of my current classes at Harvard and Boston Universities. I love working at the intersection of academia, government, and industry and have consulted for a large range of organizations and currently serve on the Science Advisory Board of Virgin Pulse.

Food Personality: Cooking in the Kitchen, the PK Way

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.

When I’m not in the kitchen, I’m at the theater. 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 produces three shows annually and its mission is to bring together individuals from all walks of life to provide an artistic outlet through the development of dramatic and musical works of art. 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 eighteenth season. (I’m now President Emeritus and Founder.) Although I grew up acting, singing, and dancing, I don’t spend too much time onstage these days. Instead, I save my performances for the kitchen and my online cooking channel and, increasingly, television, where my role as a food personality helps people approach nutrition in a fun and accessible (and delicious!) way. In 2014, I made my primetime debut on ABC’s The Taste (visit my news and events page for more details on that) as one of America’s “best undiscovered cooks” showcasing globally inspired, plant-based cuisine to show the world that healthy can still be delicious.

More About Me: Fitness Enthusiast and Wanderlust


Meditation is part of my daily life and I’ve been practicing yoga regularly for 6 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.

It probably won’t come as too much of a surprise that I also like to keep my endorphins up and my weight down by staying active. II wouldn’t be much of a role model if I didn’t practice what I preach!) 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 (as a time-qualified runner); the Maine marathon in 2011 (3:42:30, my personal record and a Boston qualifier); the Las Vegas Rock ‘n’ Roll Marathon in 2014; and the Chicago Marathon in 2015. 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, and family. We just got a dog, too, a black lab we named K’Ehleyr (who out there knows where that name is from?); she brings immense joy and exuberance to 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 the countries I’ve visited thus far include: Australia, Bahamas, Brazil, Canada, Denmark, England, Finland, France, Iceland, India, Ireland, Italy, Mexico, Netherlands, Norway, St. Martin, Scotland, Sweden, Switzerland, Thailand, and Turkey. I was born in Canada; live in the United States; and my most recent trip was to Spain. You can bet I’m already planning my next adventure…

And I dream about traveling to space.
