TED Fellow Christina Warinner is an expert on ancient diets. So how much of the diet fad the "Paleo Diet" is based on an actual Paleolithic diet? The answer is not really any of it.
Warinner's archeological journeys have taken her from Belize to Nepal. She pioneered the biomolecular investigation of archaeological dental tartar. She was a 2012 TED Fellow, and her work has been on CNN. She has a Ph.D. from Harvard.
