I seem to recall it being posted by Mike or Steven.... I can't seem to find the link after searching through the forum. Any help would be appreciated.
I think this might be what you're looking for -
Trends in Intake of Energy and Macronutrients --- United States, 1971--2000
It shows that fat as a percentage of total calories decreased due to an increase in the consumption of everything else (mostly refined CHO) however actual fat intakes in terms of grams per day showed little change over that time period.
IMO the use of percentages when presenting data on macronutrients to the public should be abandoned in favour of grams per day as percentages can lead to some confusion and many pointless arguments on internet message boards. For example many people believe that diets like Zone which allow 40% CHO are high carb diets when they're actually low energy and therefore low carb diets.
