I think the question is what is "good." What we've been told is a good diet for the last 50 or so years is really crap in my opinion. The better diet in my view is lower in sugars and carbs - especially from grains - and higher in animal fats.

We eat too much sugar, including from fruits, and starches. It's making us fat and sick and crazy, IMO. Why is the world suddenly full of obese diabetics? Hint: it's not because the human race suddenly became lazy gluttons.

And it started with the low-fat idiocy. Nutritionists have a lot to answer for.
