Yes, but what is "moderation"? What constitutes a "balanced diet"? They've been moving targets for as long as I can remember.

Meanwhile we've gone through endless cycles of "cholesterol is bad", "cholesterol is good", "only bad cholesterol is bad", "sugar is bad", "fat is bad", "fat is good, but saturated fat is bad", "carbs are bad". Eggs have gone through two complete revolutions of being bad for you and good for you. And now the new pariahs include white bread, white rice, and potatoes. Madness.
