Willett Sharpens Scope of Diet/Cancer Link |
| By Rich McManus |

Dr. Walter Willett at NIH on July 25 |
Soft-spoken, data-driven and painstakingly careful about the accuracy of his recommendations, Dr. Walter Willett gives no outward appearance of opposing the American Way of Fun. It’s just that virtually every credible study of the causes of human cancer with which he is familiar tends to oppose the lifestyle of, say, Texas troubadour Jerry Jeff Walker, who once sang, “I like to smoke and drink and have fun, jump in my car and see how fast it’ll run.”
Willett visited NIH July 25 as a guest of NCI’s Cancer Prevention Fellowship Program. In a talk he titled “Diet & Cancer: The Fourth Paradigm,” he explained that every 10 years or so for the past 40 years, a new paradigm has emerged in the science of determining diet’s link to the incidence of cancer. The distinguished Harvard nutritionist and epidemiologist gave an overview of that era, arguing that the field’s focus would most profitably turn toward an examination of energy balance, or the problem of being overweight and under-active.

High-speed video cameras that track cells, a computer model that mimics a human organ and microscopes that detect biological structures smaller than a human hair—such advances all are possible when scientists from diverse fields join together to tackle human disease.
At his July 25 lecture, “The Study of Human Diseases at the Intersections of Physical Sciences, Engineering and Biology,” National Science Foundation director Dr. Subra Suresh discussed cutting-edge collaborations to explore the mechanism, diagnosis and treatment of disease. In what NIH director Dr. Francis Collins called a “historic moment,” Suresh described his own research as well as the work of other scientists on such deadly diseases as malaria and cancer.
