I first came across Tim Spector because of COVID. His company, ZOE, launched an app which I and millions of others used to report daily on symptoms, vaccines, etc. Since then I’ve read one of his books, watched his video podcasts, read his columns and have been duly impresses. This book does not disappoint. It sums up everything he has learned about eating and sometimes reads like an encyclopedia because of it. But it’s good stuff, much of new and has caused me to rethink some of the foods I eat — and don’t eat. Recommended.
