Eat This, Not That: The Surprising Science of Personalized Nutrition

This episode, we've got the exclusive on the preliminary results of the world's largest personalized nutrition experiment. Genetic epidemiologist Tim Spector launched the study, called PREDICT, to answer a simple but important question: do we each respond to different foods differently? And, if so, why? How much of that difference is genetic, how much is due to gut microbes, and how much is due to any one of the dozens of other factors that scientists think affect our metabolic processes? You’ve heard of personalized medicine, will there be such a thing as personalized diets? And should there be? Can teasing out the nuances of how each individual body processes different foods make us all healthier? To find out, we signed ourselves up as study participants, sticking pins in our fingers, weighing our food, and providing fecal samples, all for science—and for you, dear listeners. Listen in now as we take part in this ground-breaking study, discover our own differences, and find out the early results!
