My son and I were at the chiropractor yesterday and he had us put these little pH tester papers in our mouths. We both turned out to be at around 6.5-7, which he said was too acidic. How do we get from where we are to where we need to be?

I eat a completely primal diet, but we can't afford grass fed/pastured meats and eggs. I buy almost exclusively organic fruits and veggies (unless they aren't available).

I take 3g of fish oil a day, as well as a host of other supplements.

What am I missing?
