I am busy this week crunching data for a potential research abstract, so I thought I would send in a blog substitute for today. Check out this post by Civil Eats.
It has a really neat info-graphic that shows America's estimated per capita calorie consumption from various food groups between 1970 and 2008. I find what we're eating to be more telling than how much.
The major limitation of this data is that it is derived from USDA food availability statistics and not from samples of what individuals actually consume. While they have adjusted for grocery store waste, they have not adjusted for restaurant waste. This could mean that all the oil leftover in deep-fryers is estimated into the consumption statistics.
Added sugar appears to have risen about 20%. Meat, egg, and nut consumption has gone unchanged. Grain consumption inflates in the 1980's (fear of fat trend?), and added fat inflates between 1990's and 2000's. From this data, I find it hard to blame the consumption of animal products as a cause of our current dietary tribulation, so I'm maintaining that sugar and flour are the problems.
