Around 7 or 8 years ago, when my youngest was diagnosed with many food allergies, we started eating meat. A lot of it. At the time, it was certainly my intention to move toward a primal/paleo lifestyle but I simply couldn't get off the grains and sugar.
And for probably 20 years, I've been interested in nutrition and related fields. So, yes, there is a hx there, one that goes much much further back than May.
