Harvard School of Public Health developed an insightful infographic titled, The Dollars and Sense of Chronic Disease. According to the Centers for Disease Control and Prevention, nearly one out of every two Americans suffers from a chronic disease, defined as a noncommunicable disease (NCD) prolonged in duration, including cancer, heart disease, stroke, and diabetes. Chronic diseases are the number one cause of death in the U.S and many other countries of the world.
The World Health Organization estimates that 80 percent of all heart disease, stroke, and type 2 diabetes, as well as more than 40 percent of cancer, would be prevented if people would stop using tobacco, eat healthy, and exercise.
However others believe that as alarming as the WHO results are, 40% is way too low for the correlation between food and cancer. It is estimated that between 5-10% of people ‘suffering’ with cancer today is genetic, so the balance of 90% of cancers is caused by diet, lifestyle & environmental factors.

The researches present evidence that inflammation is the link between the agents/factors that cause cancer and the agents that prevent it. In addition, they provide evidence that cancer is a preventable disease that requires major lifestyle changes.
