Matt Yglesias has a post up contrasting how the creation of health policy differs in Finland and the United States. Here's his description of Finland's process, as it pertains to school lunches:
...in 1999, parliament passed some legislation guaranteeing a nutritionally balanced school lunch. So the National Nutrition Council wrote some guidelines dictating that a properly balanced lunch would feature fresh or cooked vegetables covering half the plate, a starch (potatoes, rice, or pasta) covering a quarter of the plate, and meat or fish or a vegetarian protein alternative covering the remaining quarter.
...what's crazy about it is the way it happened. Parliament felt children should eat a well-balanced meal, and so guidelines were written by a government agency and then implemented. Like magic!
By way of contrast, here's an example of how food industry lobbyists hijack the system in the United States, courtesy of the very good American News Project:
The next issue of Mother Jones, which is either on newsstands near you or will be soon, is on how to fix food. Most of the content is not online yet, so if you want to read more you'll have to settle for this conversation we had with Michael Pollan, a longtime MoJo contributor who has more neat ideas on reforming food policy than just about anyone.
