Episode description

What if changing what kids eat at school could transform their behavior, boost learning, and even save lives? Studies show that when kids swap junk food for real, nourishing meals, behavior problems drop, focus improves, and learning soars—with one study finding a 100% reduction in suicides among youth simply by changing their diet. Across the country, schools are proving that scratch-cooked, colorful meals made from whole ingredients can fit tight budgets, reduce waste, and make kids excited to eat. By putting nutritious food at the center of education, we can help raise a generation that’s healthier, happier, and ready to learn.

In this episode, Jill Shah, Sam Kass, Kimbal Musk, and I talk about the powerful connection between nutrition and education, showing that healthy school meals can transform not just kids’ diets but their futures.

Jill Shah is the President of the Shah Family Foundation, which drives innovative work at the intersection of education, healthcare, and community in Boston. Her leadership focuses on improving access to healthy school food, supporting neighborhood food equity, and fostering collaboration between schools and healthcare to strengthen children’s physical, emotional, and social well-being. Before launching the foundation, Jill was a successful entrepreneur involved in several internet startups, including iXL, RxCentric, and Mercator Software, and later founded Jill’s List, which she sold to MINDBODY in 2013. A graduate of Providence College, she now serves on the boards of the Red Sox Foundation, Beth Israel Deaconess Medical Center, the Museum of Fine Arts, Belmont Hill School, and the Winsor School. Jill’s commitment to community innovation has earned her honors such as the Boston Chamber of Commerce Distinguished Bostonian Award and the Playworks Game Changer Award.

Sam Kass was senior policy advisor for nutrition policy in the Obama Administration and is currently an investor in several food technology start-ups. One of Michelle Obama's longest-serving advisors, Sam was the executive director of her Let's Move initiative and helped create the first major vegetable garden at the White House since Eleanor Roosevelt's Victory Garden. He is a graduate of the University of Chicago and was trained by one of Austria's greatest chefs, Christian Domschitz.

Mindsip insights from this episode:

Implement buffet model to minimize food waste

Allowing children to build their own plates from separate components in a buffet-style line dramatically reduces food waste because they only take what they want to eat.

Replace junk food with healthy options to reduce youth crime

In a study of 3,000 incarcerated youth, replacing junk food with healthier options led to a 100% reduction in suicides and a 21% reduction in antisocial behavior.

Enhance science scores through school garden lessons

Teaching science lessons in a school garden instead of a classroom can raise student test scores by as much as 15 points on a 100-point scale.

Address nutrient deficiencies in obese children for better cognitive function

The most obese children are often the most nutrient-deficient, as their calorie-dense diets lack essential vitamins and minerals, which affects cognitive function.

Implement universal breakfast to enhance student performance

Providing free breakfast to all students in a classroom, not just low-income ones, significantly improves attendance and reading and math scores by removing social stigma.

Choose real food over processed options for cost-effective meals

Pre-packaged processed foods are often more expensive for schools than cooking with fresh, whole ingredients from scratch due to added processing and margin costs.

Reintroduce Home Economics to empower cooking skills

The food industry intentionally led a successful initiative to remove Home Economics from school curriculums, resulting in generations of people who don't know how to cook.

Choose complete magnesium supplement for better sleep and recovery

Dr. Hyman recommends Magnesium Breakthrough from Bioptimizers because it contains all seven essential forms of magnesium for sleep, stress, and recovery.
