Is Fast Food Messing With Your Hormones?
Examine the results of a study1 investigating whether
fast food consumption increases one’s concentration of phthalates,
an ingredient in plastics which has been linked to multiple health
problems including hormone disruption. The study included 8877
people who recorded all the food they ate over a 24-hour period and
then provided a urine sample. Two specific phthalate byproducts
were measured (in ng/mL) in the urine: DEHP and DiNP. Find a 99%
confidence interval for the difference, μF-μN, in mean
concentration between people who have eaten fast food in the last
24 hours and those who haven’t. The mean concentration of DEHP in
the 3095 participants who had eaten fast food was x¯F=83.6 with
sF=194.7 while the mean for the 5782 participants who had not eaten
fast food was x¯N=59.1 with sN=152.1.
