Moises Velasquez-Manoff is a journalist – a science writer primarily — who has taken on the job of translating an ambitious scope of research for the non-medical reader. The central thesis is that we evolved with parasites, mostly insects and worms, and without their stimulus our immune systems get restless and look for targets that often end up being some part of ourselves. This sort of ‘friendly fire’ becomes allergies, asthma and autoimmune diseases. It’s important to point out that the many examples in the book are based on correlation, not causality. The correlations are indeed compelling, however. One, for instance, is that mothers who live on farms with animals have children with less asthma and fewer allergies. Another correlation links the end of malaria in Sardinia to a rapid rise in two autoimmune diseases, multiple sclerosis and type-1 diabetes. This book is dense with such examples.
