Are there any authoritative, proven books on nutrition? A 1-2-3 step programme to eating healthy? No, people are expected to get an intuition themselves. I think that's a great issue. Biology class teaches carbs, protein, and fats but not how to apply that knowledge. The Internet is full of anecdotes, paid meal plans by has-beens, and homeopathy. Anyone have good reads to share?
