Through the Foundation he started, Dr. Li describes in his TED talk the properties of various anti-angiogenic therapies which he and his colleagues have tested. The most promising line of investigation turns out to be the adoption of a diet high in natural anti-angiogenic substances, such as resveratrol in grapes and wine, or lycopene in tomatoes. The reason is that, as Dr. Li points out, by age 60 most men and women have cancer cells in their body -- women in their breasts, and men in their prostates -- and by age 70-80, all people have developed cancerous cells in their thyroid glands. Few of these cells, however, ever turn into malignant, metastasizing cancer, because they never trigger the angiogenesis required to furnish them with an adequate supply of blood.
Dr. Li is excited about the potential prevention of cancer (and perhaps even of obesity, because fat cells require a large blood supply as well) through the ingestion of anti-angiogenic foods. In the talk below, he gives a whole list of them, many of which you probably did not realize had those properties -- strawberries and blueberries, for example. As you watch his talk, look at the shrinkage of blood vessels which his lab slides demonstrate is caused by the growth-inhibiting substances found in common foods. Maybe you will be inspired to eat more of them!
