This Exercise pertains to a 2015 study¹ which took a Swedish family that ate a conventional diet (non-organic), and then had them eat only organic for two weeks.

Question
This Exercise pertains to a 2015 study¹ which took a Swedish family that ate a conventional diet (non-organic), and then had them eat only organic for two weeks. Pesticide concentrations for several different pesticides were measured in µg/g creatinine by testing morning urine. Multiple measurements were taken for each person before the switch to organic foods, and then again after participants had been eating organic for at least one week. The results are pretty compelling, and are summarized in a short video³ which as of this writing has had over 30 million views online. The data are visualized in Figure 1 for eight different detected pesticides, and can be found in Organic Effect. How do pesticide levels in the body differ after eating organic versus non-organic?
