My wife and I recently saw Food, Inc., a documentary by Robert Kenner. We were stunned to find out the lengths to which the public is kept in the dark about the food we eat. This is an even more important issue given that we are in a national obesity crisis.

One thing that I found particularly disturbing was the ways that food companies like Tyson, Perdue and Smithfield keep the farmers under their thumb. The farmers must continually buy expensive new equipment or face termination of their contracts with the companies. This keeps them heavily and constantly in debt.

Since most people love white meat, the food companies have genetically modified chicken so they have bigger breasts. This is achieved by injecting them with hormones. Naturally these hormones make it into our bodies, causing any number of health problems for us.

Our beef has also been tainted because cows have been taught to eat corn feed instead of grass. This deprives the beef of the natural nutrients that grass fed cows have long provided. In turn, it affects our bodies in a negative way.

What we took from the film was the need to know what is in our food. We cannot assume that our best interests are being looked after. Knowledge is the best weapon.
