Hello, hello everyone, it’s time for another great guest on the Peak Human podcast. I’m Brian Sanders the founder of Sapien.org, NoseToTail.org, and creator of the Food Lies film that I continue to work on daily while I do these podcasts and post daily on social media. You can check out clips from the Food Lies film interviews and other presentations I’ve done on the Food Lies youtube channel.
Today I’m talking to the great Michael Crawford, PhD. He is a storied researcher and has contributed a lot to our knowledge on brain development, human evolution, and marine foods high in DHA. I think the meat crowd needs to rally behind seafood a bit more and recognize its unique nutrients. He’s a sharp guy for an older fella and there’s a lot to learn in this one!
Dr. Michael Crawford is a professor and researcher at the Imperial College of London. He is part of the Faculty of Medicine, Department of Metabolism, Digestion, and Reproduction. He is the Director of the Institute of Brain Chemistry and Human Nutrition, Founder Trustee of The Mother and Child Foundation and The Little Foundation. His research focuses on (i) the biological reason why docosahexaenoic acid (DHA) has been so unique in neural signaling for the past 500-600 million years of evolution (ii) application of the knowledge to prevent and treat neurodevelopmental disorder.
To date we have organised 22 international conferences on nutrition, brain development and mental health. He also has an impressive list of publications I’ll link to in the show notes.
