Nutrient Density
The cleanest measurement of nutrients and bad stuff is the "nutrient density" IMO. The "ideal" food would have every ingredient be a density of one. For example, if a food had a density of 1 for vitimin C, that would mean that you would get exactly the recommended dose if you ate nothing but that food (assuming normal caloric intake). 2 would mean you get twice the recommended amount if you ate nothing but that food.
Thus, if a hamburger had a fat density of 2, then you know you are getting bad stuff. The current labels with Oz's of X are useless without a calculator (or quick math head).
Anyhow, there is some recent evidence that fat intake is not the problem, but instead starch and sugar intake. It is still highly controversial, but the bottom line is that there is very little evidence that the fat percentage in one's diet is the primary cause of obesity, dispite common perceptions.
There are a lot of skinney people in Asia, even office workers. Yet, the restaraunts often serve fatty meats such as pork. But, when asians move to the US, their children are just as likely to be chubby as anybody else. This is a mystery that has yet to be solved.
