Discover why cotton candy can beat a corn dog, how the perimeter-of-the-store hack simplifies everything, and what it really looks like to eat like your great-grandparents.

Episode Summary

In part 3 of the “Ancestral Mismatch” series, Ben Greenfield delivers three no-nonsense dietary strategies that anyone can implement without breaking the bank or setting foot in an overpriced health food store. You'll learn why fried seed oils are more damaging than sugar (and why Ben would choose cotton candy over a corn dog every time), how to avoid ultra-processed foods by shopping the perimeter of any grocery store, and why sourcing your food matters for your health, animal welfare, and the planet. Ben even drops his go-to travel grocery list that works at any supermarket on Earth.

Question of the Day 🗣️

What's one ultra-processed food you know you should ditch but keep reaching for, and what whole-food swap could replace it?

Key Takeaways

- Rancid heated seed oils in fried foods are more damaging long-term than sugar—lipid oxidation products (LOPs) become the building blocks of your cells and contribute to chronic disease risk.

- Ultra-processed foods (UPFs) are engineered to be addictive, stripped of nutrients, and loaded with additives, preservatives, and oxidized oils—shop the perimeter to avoid them.

- You don't need an expensive health food store—Ben's entire travel grocery list (rotisserie chicken, berries, avocados, sardines, nuts, yogurt, dark chocolate) costs under $40 and lasts days.

- Farmer's markets from May through October give you access to local, sustainably grown food—and many farmers will sell you a quarter or half cow and ship it in batches.

- Skip the fluff labels ("natural," "farm fresh")—look for USDA Organic, Pasture-Raised, MSC Certified, and Certified Humane instead.
