I'd say there's too much fixation on "carbs" and "fats" and too little on the source. Would you agree that eating a fresh apple gives a different effect compared on eating a couple of teaspoonfuls of white sugar, even if the carb and caloric content is equal? I wish there was a breakdown for the source of micronutrients somewhere.

And of course, the total amount of calories and sedentary lifestyles contribute greatly to people being overweight.

But what does contribute to the growth in rates of cancer, diabetes, heart diseas and other "diseases of civilisation"? This is not so easily answered by just breaking down the food by carbs/fats/protein.
