No, big pharma and big agra are not behind the obesity and diabetes epidemic you name.

Here is a hint of what is behind the obesity and diabetes epidemic: driving cars everywhere, including shuttling kids everywhere over hyped paranoia over stranger-child kidnapping, drinking sugar rich soda pop by the gallon, addictions to hand-held cell phone games and texting and aps (replacing after school sports games), and lousy store food variety in too many neighbourhoods inhabited by lower income folks who thus eat less greens and more junk out of boxes.

Nothing to do with "organic" (roll eyes) or big pharma...
