Healthy Hedonism: The P.K. Way

Eating Delectably Without Deprivation


Thank you for visiting my website. I am a Harvard-trained nutrition scientist and educator with more than fifteen years of experience researching diet, obesity, and chronic diseases; studying how people eat; and teaching students about why what you eat matters, farm to fork. My mission? To bring together my passions for science, food, health, and sustainability to help people translate principles of sound nutrition and green eating to their plates in delectable ways, always keeping pleasure (that’s the “hedonism” part of the equation) at the center of the plate. After all, it doesn’t matter how “healthy” something is: if it’s not tasty, you’re not eating it--and neither am I!


For hundreds of recipes and tips on Cooking and Eating the P.K. Way, please visit my blog or watch videos on my cooking channel. (May include martinis and buttercream. Not together.) And contact me to see how I can help you meet the goals of your next event, whether on stage, television, or radio. I look forward to hearing from you!
