Low-Carb Science 2010


Updated December 26, 2010

Oftentimes, the way science is portrayed in the media can be a problem. Ideally, what we know about the world is built piece by piece, with lots of scientists checking and cross-checking each other until a pattern emerges. However, the media often chimes in on this study or that one and often influences public perception of an issue. It's important for us to understand the process of science so we can put the information we get in context.

When a news or media story comes out about research regarding diet, I often try to put it in context for my readers. Here are some of the stories I covered in 2010. Check here for less sciency low-carb blog posts.
