This Exercise pertains to a 2015 study which took a Swedish family that ate a conventional diet (non-organic), and then had only organic for two weeks. Pesticide concentrations for several different pesticides were measured in µg/g creatinine by te 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 which as of this writing has had over 30 million views online. The data are visualized in Figure 1 for eight different detected and can be found in OrganicEffect. How do pesticide levels in the body differ after eating organic versus non-organic?

![The Organic Effect
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 OrganicEffect. How do pesticide levels in the body differ after eating organic
versus non-organic?

Eating Organic and 3-PBA Levels
We first study 3-PBA, a commonly used insecticide found in grains, fruits, and vegetables. How much higher are 3-PBA concentrations
while not eating organic versus eating organic? A bootstrap distribution based on 1000 samples of the mean concentration before the
switch minus the mean concentration after switching to organic is shown in Figure 2.
