Thanksgiving is near, which means many families will come together with loved ones over a shared meal that celebrates abundance. But along with their appetites, guests bring their food preferences. As omnivores, vegetarians, vegans, or those interested in eating sustainably grown food gather, a meal can turn into a battleground for arguments that go way beyond what’s on the plate.

On this episode, we explore our desire to make food choices that benefit our health — and perhaps the health of the planet — and why we get so passionate about these choices. Are we taking the old saying “We are what we eat” too seriously — using our food choices as an anchor for identity? Gastroenterologist and winner of the BBC’s MasterChef competition Saliha Mahmood Ahmed describes mouth-watering ways to combine delicious flavors that promote good gut health, and why she thinks it’s perfectly fine to occasionally eat a jam-filled doughnut. Food writer Alicia Kennedy talks about her choice to become first vegan and then vegetarian, and why her family still seems to think it’s a phase.

And we visit a farm that was created with hard work, enthusiasm, and idealism: small and sustainable, with a mission to make humanely raised animal products available to many people … but a closer look reveals that things may not be idyllic as promised.
