Dean Ornish quotes:

Think about it: Heart disease and diabetes, which account for more deaths in the U.S. and worldwide than everything else combined, are completely preventable by making comprehensive lifestyle changes. Without drugs or surgery.

With everything that you can imagine at our fingertips, many of the social interactions that help tie people together in a community have faded away. Are communities traditionally built on relationships, trust and familiarity a thing of the past?

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.

Whether it's by helping us search for health-related information, connecting us with doctors through online portals, or enabling us to store and retrieve our medical records online, the Internet is starting to show the promise it has to transform the way people interact with and improve their own health and wellness.

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 don't understand why asking people to eat a well-balanced vegetarian diet is considered drastic, while it is medically conservative to cut people open and put them on cholesterol lowering drugs for the rest of their lives.

Joy of living is sustainable; fear of dying is not.

The need for love and intimacy is a fundamental human need, as primal as the need for food, water, and air.

The need for connection and community is primal, as fundamental as the need for air, water, and food.

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.

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

There's no point in giving up something you enjoy unless you get something back that's even better, and quickly.

While the digital age has done so much to improve our world, it has dramatically changed our social structure, often further isolating us from each other.

People who are lonely and depressed are three to 10 times more likely to get sick and die prematurely than those who have a strong sense of love and community. I don't know any other single factor that affects our health - for better and for worse - to such a strong degree.

The healing power of love and relationships has been documented in an increasing number of well-designed scientific studies involving hundreds of thousands of people throughout the world.

We all know we're going to die one day, but who wants to think about it? What's sustainable is joy, pleasure and freedom.

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.

If I eat mindlessly while watching television, reading, or talking with someone else, I can go through an entire meal without tasting the food, without even noticing that I've been eating. The plate is empty but I didn't enjoy the food - I had all of the calories and little of the pleasure.

A valid scientific theory is predictive, verifiable, and replicable. To me, that's beautiful.

The Internet has transformed many parts of our daily lives, touching everything from how we find information to how we go shopping, get directions, and even stay in touch with friends and family.

I never give up hope.

The reason I spend so much of my time doing science is that the whole point of science is to help people resolve conflicting claims by saying: 'Show me the data.'

In general, losing weight is a good thing for those who are overweight, but it's important to lose weight in a way that enhances your health rather than one that may compromise it.

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.

What matters most is your overall way of eating and living.

Science is simply a powerful way of understanding what's real and what isn't, what's true and what's not. It can help us determine what works, what doesn't, for whom, and under what circumstances.

Poor health is not caused by something you don't have; it's caused by disturbing something that you already have. Health is not something you need to get, it's something you have already if you don't disturb it.

Curious patients are more receptive to new ideas, and those who engage their health practitioners in a dialogue are much more likely to adhere to these recommendations.

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.

When you grow up in an extended family, or in a stable neighborhood with two or three generations of families who live there, you feel seen. Not just the good things you've done, the stuff you put on your resume. You know they've seen you in your dark times, when you've messed up - but they're still there.

I grew up in Texas, eating meat five times a day, and I liked meat. But I began being a vegetarian when I was 19 because I found that I felt better.

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.

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.

Eating a vegetarian diet, walking (exercising) everyday, and meditating is considered radical. Allowing someone to slice your chest open and graft your leg veins in your heart is considered normal and conservative.

When I talk about forgiveness, I mean letting go, not excusing the other person or reconciling with them or condoning the behavior. Just letting go of your own suffering.

Stress is not so much what you do, but how you react to what you do.

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.

Love and intimacy are at the root of what makes us sick and what makes us well...I am not aware of any other factor in medicine-not diet, not smoking, not exercise-that has a greater impact.

We all have an inner teacher, an inner guide, an inner voice that speaks very clearly but usually not very loudly. That information can be drowned out by the chatter of the mind and the pressure of day-to-day events. But if we quiet down the mind, we can begin to hear what we're not paying attention to. We can find out what's right for us.

Real power is not given to us or even created; real power is realized. It comes from realizing an inner sense of peace, self-worth, and happiness.

An educated patient is empowered; thus, more likely to become healthy.

People don't dislike change, they dislike being changed.

Our survival depends on the healing power of love, intimacy and relationships. As individuals. As communities. As a country. As a culture. Perhaps even as a species.

I usually find that the process of discovery is more interesting than the answers.

Awareness-mindfulness-is the first step in healing. In Counterclockwise, Dr. Ellen Langer eloquently describes how becoming more aware of our beliefs and expectations allows us to powerfully transform our lives for the better. A pioneering, beautifully-written book.

When I use the word spirituality, I don't necessarily mean religion; I mean whatever it is that helps you feel connected to something that is larger than yourself.

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

One of the reasons my father ... became a dentist was so he could always be home for dinner and spend weekends with his family. At one point he had thought about being a musician, but he said, I'm not going to do that because I'd be on the road all the time and I wouldn't be with my family.

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.

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