Over time, years of meditation gave me glimpses of the interconnectedness and interdependence of all life. I experienced that on one level we are alone, separate, apart from everyone and everything; on another level, we are the Self in different disguises, different names and forms, a part of everyone and everything. This experience of interconnectedness is part of spiritual traditions and the perennial wisdom in virtually all religions and cultures.

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.

I've found that if I tell somebody 'Eat this and don't do that,' it's not only not helpful, it's counterproductive because even more than being healthy, we want to feel free and in control, and as soon as somebody tells us to do something, there's a tendency to do just the opposite.

I'm a big admirer of Walter Willett's work. I think he's done some really important research. He and I agree on most things.

Although scientists can often be as resistant to new ideas as anyone, the process of science ensures that, over time, good ideas and theories prevail.

Whether you're six or sixty, if you go on a diet and lifestyle program and feel constrained, you're likely to go off it sooner or later. Offering a spectrum of choices is much more effective; then, you feel free and empowered.

People tend to think of breakthroughs in medicine as a new drug, a laser, or a high-tech surgical procedure. They often have a hard time believing that the simple choices that we make in our lifestyle. What we eat, how we respond to stress, whether or not we smoke cigarettes, how much exercise we get, and the quality of our relationships and support can be as powerful as drugs and surgery. And they often are.
