In Defense of Food

What should we eat? Until the early 20th century, the answer to this question was simply dictated by what was grown nearby, readily available, and unspoiled. But 100 years later, the struggle over what to eat has become one of the most complicated, confounding, and urgent battles facing the world. Based on Michael Pollan's best-selling book, In Defense of Food shows how a combination of uncertain and incomplete science, politicians, and clever marketing campaigns have shaped the world's eating habits in ways that have made us continuously less healthy. From crowded American supermarkets to the vast plains of Tanzania, In Defense of Food examines how the modern Western diet, especially as it has evolved over just the past few decades, is doing serious damage to our health.
