For more than 2,800 years, the concept of eating plants in their whole-food form has struggled to be heard and adopted as a way of life. However, recent evidence shows that more than ever a plant-based diet is not something to be ignored. In fact, eating a plant-based diet has become an urgent matter from several perspectives. Not only will it improve your health -- and the evidence behind this claim is now overwhelming -- but it will also dramatically reduce health care costs, as well as reduce violence to our environment and to other sentient beings.

The fact is our nation's economic stability, already crumbling due to the repeated bursting of bubbles such as technology and housing, has been hard hit by spiraling health costs that seem to have no end in sight. Despite this, as a nation, we are sicker and fatter than we have ever been. The epidemic of obesity and diabetes, especially in the young, forecasts an economically unsustainable public health challenge with the gloomy prophecy that today's children may not outlive their parents.

Who will protect the public? Not our government: The U.S. Department of Agriculture's nutrition pyramid is laden with food that will guarantee millions will suffer ill health. Not the American Dietetic Association, which is controlled by food corporations. Not the insurance industry, which profits by selling plans to the sick. Not the pharmaceutical industry, which pockets billions from chronic illnesses. And not the medical profession, in which doctors and nurses receive virtually no training in nutrition or behavioral modification, and are handsomely rewarded for administrating drugs and employing technical expertise.

What can save America is a plant-based diet, which will help individuals recover their good health, and which in turn will set our health care system right (as well as our economy). However, for this plant-based diet to take hold, the public must be endowed with nutritional literacy, the kind of knowledge that is portrayed in the new documentary, "Forks Over Knives."

"Forks Over Knives" focuses not just on the research that both of us have been engaged in over the last four decades, whether in China and Cornell or at the Cleveland Clinic; it also traces the journey of several Americans as they move from a lifetime of eating mostly animal-based and processed foods to a whole food plant-based diet, and the extraordinary medical results that follow. It is educational, entertaining, and literally life-saving.

Please see "Forks Over Knives." It could transform your life in ways you never thought possible. And it may just help start the seismic revolution in health care this country so badly needs.
