Internet Research: If we are what we eat... What is America?

I have heard a quote before that says " you are what you eat" and this got me thinking... If we are what we eat then what is America? How do people view us through the way we eat, what we eat and how we advertise our foods. Some statistics on the way Americans eat are as follows:
*"Less than a third of Americans are cooking their evening dinners from scratch, according to a new survey by the Institute of Food Technologists, The data shows a seven percent percent reduction over the past two years. Although 75% of Americans are eating their dinners at home, nearly half those meals are fast food, delivery, or takeout from restaurants or grocery delis. In fact, Americans spent more on fast food last year than on education." (http://www.gather.com)
* "Females and males in the age group of 2-9 eat more than three times the daily recommendation allowed for sugar. (http://www.associatedcontent.com)
*"The U.S. Surgeon General report declared that obesity is responsible for 300,000 deaths every year (http://www.americansportsdata.com/obesityresearch)
*"With the average adult woman weighing in at a staggering 163 pounds" (http://www.americansportsdata.com/obesityresearch)
*"Perhaps the most shocking statistics underscoring obesity in the United States is that 400,000 Americans (mostly men) fall into a super-massive 400+ pound category"(http://www.americansportsdata.com/obesityresearch)
*"Americans eat the most fast food... Burgers dominate the US fast food industry, with burger fast food taking more than half of total fast food expenditure." (http://www.euromonitor.com/Who_eats_the_most_fast_food)
