Let Them Eat Dirt

Wall Scholar Dr. Brett Finlay spent 30 years studying bacteria as something bad; now he and fellow researchers (in his lab and all over the world) have turned their gaze to bacteria as something good—and essential to your child’s well-being. Dr. Claire Arrieta’s research shows that babies who are missing key intestinal microbiota are more likely to develop asthma later in life. This groundbreaking study and others of its kind inspired Brett and Claire to write the book, to inform the important choices parents make early on that will affect their kids’ lifelong health.
