Michael S DonaldsonMichael Donaldson, PhD, is a chemical engineer and independent nutrition researcher with more than 28 years of experience in raw food science. He holds a doctorate in chemical engineering from Cornell University, with an emphasis in biochemical enginering.After completing his graduate studies, Dr. Donaldson joined Hallelujah Diet, where he became the organization's one-man research department, developing enzyme-based analytical methods to evaluate the biological vitality of raw food products. That work grew out of a deceptively simple question: how do you prove, scientifically, that a food has not been cooked? The methodology he developed became the foundation for more than two decades of independent comparative testing of barley grass juice powders and other green food products available in the United States market.His research has spanned a wide range of nutrition topics - including dietary interventions, bone health, metabolic disease, and micronutrient science - with a particular focus on the intersection of analytical chemistry and whole-food nutrition: understanding not just what living foods contain, but whether what they contain survives the journey from field to consumer. He lives in Zillah, Washington. Learn more about his research at twhealthproducts.com. Read More Read Less
