With all of the flu talk in the news lately makes me highly appreciative of primal living. Knock on wood, I've been following primal for over a year now and haven't had ANY flu or seasonal allergy issues. I'd like to think that its attributable to the primal diet rather than just getting lucky.

I wonder if there is any correlation over time with the increase of grains/processed foods consumption and the number of people that get the flu. Did people get the flu in the 50s and 60s as often as we do today?
