An old hippy seeker once told me that after investigating all religions and beliefs, he came to the conclusion that life is about the daily struggle within ourselves to conquer our temptations: i.e. to let our better natures overcome our baser instincts... Since I was too lazy and pre-occupied to check it out myself, I accepted his conclusion and tried to live by it.
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.
