I am as non-accepting of medical quackery and unscientific approaches as anybody else. I've grown up as a card-carrying scientist, and I know the power of science to answer questions, and for many questions I don't know of anything better than scientific approaches to answer them.

Meaning is malleable: take it out, you get nihilism and despair. Put it in, you get sacredness and something most special.

Love and intimacy are at the roots of what makes us sick and what makes us well, what causes sadness and what brings happiness, what makes us suffer and what leads to healing...I am not aware of any other factor in medicine- not diet, not smoking, not exercise, not stress, not genetics, not drugs, not surgery- that has a greater impact on our quality of life, incidence of illness and premature death from all causes.

Even more than feeling healthy, most people want to feel free and in control.

When most people think about my work, they think about diet. To me, diet has always been the least interesting part of it.

Because the biological mechanisms that affect our health and well-being are so dynamic, when people change their diet and lifestyle, they usually feel so much better, so quickly; it reframes the reason for changing from fear of dying to joy of living. Also, the support that patients give each other is a powerful motivator.

At a time when 20% of people in the US go to bed hungry each night and almost 50% of the world's population is malnourished, choosing to eat more plant-based foods and less red meat is better for all of us-ourselves, our loved ones, and our planet.
