Wits Guts Grit is inspired by the many questions acclaimed science writer and mother Jena Pincott explored about the natural forces that shape children's minds and health. What if we identify the microbes that support stress resilience and find ways to expose our kids to them? What if we reintroduce the mineral magnesium, deficient in almost every child's diet? Would it reduce anxiety and increase bounce back, as the science now suggests? What if memory and learning could improve measurably after eating certain foods--such as blueberries--high in plant chemicals called flavonoids, or after certain forms of exercise? These and many more questions led Pincott to simple, all-natural "biohacks"--experiments inspired by current research and theory--complete with instructions on how to undertake them to help your own children strengthen their wits, guts, and grit.
