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.

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.

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.

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