I think they are very hard to avoid. I last lived in the us in 2016 and had "gone clean" in 2013. I was off of everything I knew to be toxic in food, beauty, household etc. I was filtering the air and water in my apt (so gross). I did multiple detox protocols over those years as well.

Then I moved to Thailand had had a huge immediate health improvement. Over the next 10 months, I watched my finger and toenails grow out a brown tinge and finally go completely to pink. The hairdresser I was seeing said my hair was "dead" when she first saw it and then by the end of the year she said it had improved.

Even for California, people thought I was crazy for all the precautions I took. Now I think they were not enough.
