Since 1909, has American carbohydrate consumption gone up or down?
This is somewhat of a trick question, because the trends in the last 40 years have been upward. Overall in the last century our carb consumption is lower, because at the turn of the century we were eating almost entirely grains, and as our prosperity increased especially after the world wars, we began to eat meat much more regularly. Now we are eating more carbs (especially simple carbs, like HFCS) than we were forty years ago, but less than 100 years ago.

Up: we eat more fat now, but the percentage of calories from fat has gone down, because we are eating so much more sugar.
