Human evolution has had its diet du jour for thousands of years. Through the ages one would expect that life expectancy, brain size and height would have improved with the advent of agriculture, 10,000 years ago. That assumption would be wrong. In fact for various reasons, at the advent of agriculture, life expectancy declined from 40 years to 20 years and there is evidence that height and brain size also declined. The E3 Nutrition Lab at Washington University in St. Louis sizes up humans's dietary progress from three related perspectives: evolutionarily appropriate, environmentally sustainable and economically affordable. Lora Ianotti is the Diretor of E3 Nutrition Lab and Associate Dean for Public Health at Washington University. She takes Farm to Table Talk back millions of year and then forward again to consider the issues of today and tomorrow's diets. https://e3nutritionlab.wustl.edu
