A person who eats trendy foods to fit in with their health-conscious friends. Locally-sourced, organic, free-range kale, anyone? May also do yoga (or just wear
yoga pants), and can talk for hours about their latest
juice cleanse. Typically found with an iPhone in one hand and a
strangely green-brown colored "beverage" in the other. Usually they're not buying all that trendy food with their own money.
My sister in law is such a herdivore. She will eat anything that she sees on Dr. Oz or at Whole Wallet Foods. If you ask me, it's a
waste of money, but her hubby's loaded and doesn't want to hear about her latest
juice cleanse all day, so he gives her a c-note and sends her to yoga class.
