Natural products that appeal to the paleo population were everywhere at Expo West 2015. Some paleo brands—which exclude dairy, grains, legumes (and obviously fillers or stabilizers) that a person living 10,000 years ago wouldn't recognize—highlighted their caveman suitability by placing "primal" or "paleo" on their packaging.

Plus, for many products, super-simple ingredients lists also meant they're vegan.
