You make good points. I guess what I really wanted to say is that 90% of the time when people talk about toxins and try to offer up a solution, they don’t even know what they’re trying to talk about. There certainly are substances that bio-accumulate. And as you say, understanding what is actually there, what can be measured, what is problematic, and then reducing intake should be key in solving the issue.
Another thing I think is important to understand is that the science is continually evolving. I’ve encountered plenty of doctors who insist you should eliminate saturated fat from your diet as much as you can, and that’s key to reducing your odds of heart disease. This is the old hypothetical model of heart disease. Modern studies tend not to agree. But people are still being told the same old things.
