Having upset the dietetics industry by writing about stuff in which he has no qualifications, he then turned his focus to something else he is unqualified to write about, education. In Free Schools, David takes a parent’s eye-view of the research and concludes that all the rolling green hockey fields and architect designed amphitheatres won’t make a jot of difference to the education your child is likely to receive.
In Eat Real Food, David returns to the topic of human nutrition and delivers the ultimate practical guide to avoiding the two most toxic substances in the modern food supply, sugar and seed oil.
His new book, Taming Toxic People, looks at the phenomenon that damages businesses, seeds mental disease and discomfort, and can bring civilisations to the brink of explosion – the psychopath.
