Food & Nutrition:
What Everyone Needs to Know
Evidence-Based Answers to Essential Questions

"The Nutrition Doctor" P.K. Newby sorts food fact from fiction and nutrition science from nonsense when it comes to what we eat and why it matters, answering “need to know” questions related to all things food, from farm to fork. Nutrition confusion ends here.

I cooked my heart out for the extraordinary Nigella Lawson (aka, the Domestic Goddess) in the search for America's "best undiscovered cook" on ABC's 2015 season of The Taste. You can now download episodes here. (I'm in episodes 1 through 4 and am especially prominent in episode 4.)
