Prem51, I think you'll find this 10 minute lecture from 2011 by Dr. Joseph Pizzorno, ND interesting. Pay particular attention to the POPs - [Persistant Organic Pollutants] - and Diabetes slide and discussion, minutes 08:16 - 09:04...
Something else that I learned from Dr. Pizzorno is that toxins, which include POPs and heavy metals, are
partitioned off from the body in our fat cells. That's why it's so important to have regular bowel movements and to regularly eat fiber rich foods when losing weight so as those toxins are released into the colon, they bind with the fiber and are carried out of the body so they're not reabsorbed.
If anyone is interested in learning more from Dr. Pizzorno, there's quite a few good interviews with him on YouTube from 2017 when his book was published. Two interviews with Dr. Pizzorno that I enjoyed were with Dr. Trevor Cates, The Spa Doctor Podcast...
and with Dave Asprey, Bulletproof Radio...
This is the reason why I want to continue losing weight.
