Angiogenesis means the growth of new blood vessels, or you can get a more detailed definition from wikipedia. Why go against the growth of new blood vessels?

He found out that you can achieve anti-angiogenesis simply from our diet, not necessarily from drugs. The implication of this is a natural and relatively cheap cure of many of our diseases.
