Eric,
Does it really matter?
Do you really want to eat that crap.
I am sorry but there are several things that I don't want anywhere near my food.
1.) Deification and other bodily fluids.
2.) Heavy metals.
3.) Petroleum products.
You can't tell me well it's just a little bit of feces.
Yea it's just a little bit of neurotoxin.
What do they say "what doesn't kill you makes you stronger".
That may be fine for animal feed, but it's getting to the point the point where no matter how much effort you can't protect yourself and your family from these things.
We are starting to see so many health problems in our western culture. Little by little so many getting traced back to diet.
Are you familiar with the engineering term "Accumulation of Tolerances"
It's about predicting reliability. Say were building a car, and each part can be 1 mm off.
After you connect 10 parts together in a chain, you can have on occasion be 10 mm off.
Well it's like that with tolerating toxins.
Yea we can handle so much mercury and so much hexane and so much BPA, PFOE, Flouride, Aluminum, Cadmium etc. etc. etc ...
Even Sodium.
With each product it pushing that limit.
But in the real world we eat 20 products per day.
End result, Cancer, Autism, dementia, heart attack, diabetes, stroke, Asthma, allergies, lower IQ's, and a plethora of other problems.
How can anyone sort out what's causing what.
It's like badly written source code. You can't tell where the problem is. The only way out id to start correcting ugly code a piece at a time and without fail, the errors start going away.
