Whether sensational headlines from the latest study or anecdotes from celebrities and food bloggers, we're bombarded with "superfoods" and "best ever" diets promising to help us lose weight, fight disease, and live longer.

At the same time, we live in an over-crowded food environment that makes it easy to eat, all the time.

The result is an epidemic of chronic disease amidst a culture of nutrition confusion--and copious food choices that challenge everyday eaters just trying to get a healthy meal on the table.

In her book, Food & Nutrition: What Everyone Needs to Know, Harvard- and Columbia-trained nutrition scientist Dr. P.K. Newby examines 134 stand-alone questions addressing "need to know" topics, including how what we eat affects our health and environment, from farm to fork, and why, when it comes to diet, the whole is greater than the sum of its parts-and one size doesn't fit all.

Listen as Newby joins Dr. Friedman to debunk popular myths and food folklore, encouraging readers to "learn, unlearn, and relearn" the fundamentals of nutrition at the heart of a health-giving diet.
