If the old saying is true that we are what we eat, Americans may want to sit up and take notice: the Center for Food Safety has estimated that up to 75% of processed foods on grocery store shelves contain genetically engineered ingredients. Even the most health-conscious individuals have likely been unable to avoid consuming genetically modified foods, especially since food distributors are not required by law to label them. We explore why some people wanted to alter the composition of crops in the first place, how GM food can impact your health, and what your elected representatives are doing in response to public concern. This is a lot to digest (so to speak), but we are confident you will emerge a more alert consumer.

At a local farmers market, we ask some of San Diego’s most health-conscious consumers if they’re aware of genetically modified foods. Continue watching to study the science behind the modification process.
