SciAm: Could Diet Change Help Treat Blood Cancer or Transplant Patients?

The essential role valine plays in blood should not come as such a surprise, says Linheng Li, a stem cell biologist at the Stowers Institute for Medical Research. Some people who eat a low-protein vegetarian diet are known to develop anemia, a disease characterized by low levels of red blood cells.

Tell someone you could treat blood cancer via diet, even a month ago, you'd get laughed out of town. Just goes to show - slavish devotion to existing belief systems without a sense of humbleness, without recognition of the fallibility of human knowledge, is very unwise. Most science is but a set-point, not an absolute. To think of it otherwise is actually anti-science. Zhuangzi:  Men honor what lies within the sphere of their knowledge, but do not realize how dependent they are on what lies beyond it.
