Today, I was at the mind, body, spirit and products advertising promotions expo

So I got myself tested for PH and metal?
PH came back as 7.3 as expected. Go the raw food!! The person said, out of all the people she tested this expo I was only the second with a 7.3, all the rest were acidic. All the raw foodist should head over there and show them were all alkaline.
Following that she tested for heavy(ionic) metals, there were some lead and mercury. So that got me thinking where I can get those metal in my body. Now I been water fasting for roughly 40 hours. Just broke it about 5 hours before the expo.
1. Tap water(unfiltered). I been drinking mostly boiled tap water, which does nothing to remove the metal in the water.
2. Food? metal in food? Soil contamination?
3. Air we breath? What can we do about that?
4. Fish or meat? well I am am 90% vegan(50% of that is raw) and 10% crap.
Can else add where else I can get metal in my body?
