26. Vanessa Rissetto: Seed Oils, Ultraprocessed Foods, Nutrition Myths, and More

In this episode, Sam sits down with Vanessa Rissetto, a registered dietitian, Scorpio, and founder of Culina Health. They talk about the brokenness of American healthcare and how Culina is creating an inclusive nutrition economy before deep diving on all the buzzy topics we can't seem to escape in 2025. What are ultraprocessed foods doing to our bodies? Are seed oils really that bad? Are GLP-1s like Ozempic safe for aesthetic weight loss purposes? Listen to this episode if you've ever asked yourself any of those questions, if you're struggling with food noise in the wellness space, or if you want to hear realness from someone who's highly trained and certified to advise you...instead of a healthtokker.
