In Episode 123 of The Eat for Endurance Podcast, I’m joined by sports dietitian and nutrition communications specialist, Marie Spano, MS, RD, CSCS, CSSD.
Marie is the Sports RD for the Washington Nationals and Atlanta Hawks, and she has previously worked with powerhouse teams including the Atlanta Braves (World Series champions in 2021), Chicago Cubs, and more. I’ve admired Marie’s work and have been trying to get her on the show for many years, so I’m extra excited to finally share this conversation with you.
In this episode, we’re diving deep into the food matrix, including what it is, why it matters, and how it impacts nutrient absorption. As Marie explains, “Food is so much more than the sum of its nutrient parts.” We break down how nutrients interact within foods, how processing or cooking can change them, and what this means for fueling, recovery, and performance.
Marie and I discuss:
- What the food matrix is and why it’s so important for athletes
- How the food matrix impacts nutrient absorption, hunger/satiety, gut health, and more
- Real-world examples of how protein, carbs, and fat behave differently depending on food form
- The role of fiber, antioxidants, and other plant compounds in long-term health and performance
- Why processed foods (like sports drinks, juice, or protein powders) can be the best choice for athletes in certain situations

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
