There is less pollutants in the blood of young people

« We found that older compared with younger adults with morbid obesity had levels of PCBs, OCPs, and PFCs approximately two‐ to fivefold higher at the time of bariatric surgery. More importantly, with rapid weight loss, older adults had greater increases in serum levels of the lipid‐accumulating environmental toxicants PCBs, OCPs, and PBDEs. In contrast, PFCs, which bioconcentrate in the serum, kidneys, and liver (28, 29), showed a completely different response to weight loss. While the older group had higher baseline concentrations, the younger group had a greater increase in the PFC serum levels associated with weight loss. It is important to note that our “older” group was still relatively young, with a mean age of only 47 years. Therefore, they have the prospect, especially after weight loss, of living several more decades with increased exposure to these toxicants. »
