As long we impart to nutrition the mediagenic volatility associated with the weather, we can all but guarantee that our understanding of what is good for us will remain very much clouded over. There will also be a very high chance of us acting like meatheads -- and being fed a steady diet of headlines accordingly.
Here's what we actually know. In the U.S., more dairy in the diet -- of whatever variety -- is generally associated with better health and weight outcomes. But that is likely because in the context of our culture, more dairy means less soda. In global context, some of the world's healthiest diets and most convincing intervention trials have de-emphasized, or even excluded dairy.
