Before I start I'd like to say that I am not a food expert or a politician. I'm a food photographer who recently watched Food Inc ... and I have a sister who is a hippie and bit of a food activist. I like food & I enjoy eating. I, like many people/women/eaters, spend a good deal of time thinking about what I eat and how it will affect my body.
It is no deep secret that natural less processed foods tend to be healthier for our bodies. What IS less widely known is that we're presented processed unhealthy food partially because it's what we buy, but also because of food subsidies, policies, and big corporations. You don't have to be a political scientist to begin to understand the problem, and I have no interest in fully deconstructing it. (I dropped my dual major in political science to a minor mostly because I find politics depressing.) What I can take away from both my 'International Political Economy' class (even sounds depressing right?) and Food Inc is that we are more powerful than we know as consumers. If we buy it - they will produce it. If we demand other products we can affect change! The Story of Stonyfield Farms in Food Inc. is very inspiring and Gary (CEO aka CE-Yo) talks about this very idea.
