The United States has experienced a major health transition in the last 150 years, which has included an increase in the prevalence of obesity, diabetes and coronary heart disease. As these conditions are heavily influenced by food choices, it is important to understand how the American diet has changed over this time period. This talk will describe qualitative and quantitative changes in American food habits that may be relevant to modern disease patterns.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
