In any controversy it can be helpful to consider the views of disinterested parties. So, on the subject of agricultural policy and practice, it's worth noting that an unimpeachably neutral group has joined the ranks of those who prefer organic foods over foods produced with the help of synthetic chemicals. That group is 40 Swiss rats.
A team of Swiss and Austrian scientists recently concluded a 21-year study of organic wheat production. As an "integrative method" for assessing quality, they gave lab animals a choice of biscuits made from organic or conventional wheat. The rats ate significantly more of the former. The authors call this result remarkable, because they found the two wheats to be very similar in chemical composition and baking performance.
