I have been considering how to write on nutrition. One of the biggest issues in the public health arena is obesity. We all know that personal responsibility and social responsibility are two arms of the same issue. Since, education is the preferred tool for creating greater personal responsibility, policy was aimed at increasing nutritional education. However, as many of us know, rarely do we eat correctly. With this in mind current policy is aimed at changing the environment. This is seen in the movement to remove unhealthy snacks in the school vending machines, smaller portions served at restaurants, healthy food choices at places like McDonald's, and the willingness for restaurants to accommodate low fat and low salt diets.

But, there is more to the story than simply too much food. Marion Nestle, MD, MPH writes and lectures extensively on the politics of food. I feel that a lecture that she gave at Google in 2007 serves as a very good general overview as to what has happened in the food industry that has made significant changes in the consumption of food. The video is about an hour long but, is worth listening to (in smaller portions if you prefer).
