On May 22, I had the pleasure of talking with Jamie Oliver after he received the Healthy Cup Award from the Harvard School of Public Health. He is as warm-hearted and compassionate in person as he is on TV, and I was touched by his fervor to help kids around the world lead healthier, longer lives.

I came away from our meeting understanding one point above all else: He inspires each and every person to take responsibility for transforming our food system.

Members of the Nutrition department at the Harvard School of Public Health have been advising Google food service to ensure healthy choices since 2009. During this summer, Google executive chef and nutritionist Olivia Wu and I discussed the appropriate portion size for desserts. Since all Google meals are free and employees get unlimited servings, I commented that it’s important for Googlers to learn about mindful eating along with healthy portion sizes and the nutrition of their food.

My Harvard colleagues and I recently developed the Healthy Eating Plate, a healthier, clearer version of USDA’s MyPlate.
