It’s easy to scare people about what’s in their food, but the danger is almost never real. And the fear itself kills.

Take the panic over genetically modified organisms, or GMOs. Ninety percent of all corn grown in America is genetically modified now. That means it grew from a seed that scientists altered by playing with its genes. The new genes may make corn grow faster, or they may make it less appetizing to bugs so farmers can use fewer pesticides.
