In Food and Nutrition: What Everyone Needs to Know®, nutrition scientist and gastronome Dr. P. K. Newby provides a sweeping overview of the many interrelationships between humans, land, and food. What are today's major global nutrition problems-and are they preventable? Is it possible to retrain the palate to prefer healthier foods? How exactly do our dietary choices impact the land, water, and air that surround us? And what's the best way to live to 100, and beyond? In 147 stand-alone questions spanning twenty chapters, Newby examines topics including key nutrition concepts behind good eating; the technology, biology, and psychology of food choices; how diet affects our health and environment; and evidence-based tips for creating lasting behavior change. At the same time, Newby debunks popular myths and food folklore, challenging listeners to "learn, unlearn, and relearn" the fundamentals of nutrition at the heart of a health-giving diet. Her passion for all things food shines through it all, as does her love of the power of science, technology, ingenuity, and engineering to help create healthier, more sustainable diets for everyday eaters and students of nutrition alike.
