From bestselling author and Glucose Goddess, a groundbreaking guide to the science of pregnancy nutrition that empowers mothers-to-be to improve their baby's health for a lifetime. Most pregnant women are told: "Eat whatever you normally eat. Your baby will get what he needs from you." But science tells a different story: your diet during pregnancy shapes your baby's health for life . And somehow, no one has told you the rules--until now. When biochemist Jessie Inchauspé became pregnant, she uncovered striking research: choline, DHA, protein, and glucose are four key nutrients that influence a baby's development in the womb; yet most women don't get nearly enough of the first three and too much of the fourth. In this book, Jessie reveals science-based hacks to: Support your baby's brain development, cognitive growth, and emotional resilience Help lower their risk of health challenges later in life like asthma, allergies, and diabetes Influence your baby's body composition, organ function, and long-term metabolism With guidance on supplements, nausea, labor, breastfeeding, meal plans, and recipes, as well as Jessie's personal journey, this book reveals the extraordinary power mothers hold during pregnancy --and is an essential companion for every parent-to-be.
