Here is a quote from Danny Roddy's blog- I think this guy is really on to something!--------
According to Professor Bruce Ames from the University of California, Berkeley, our short-term survival is achieved by prioritizing the allocation of scarce micro-nutrients. He believes that this "triage theory" has enormous implications for human health and aging.
Triage theory explains that age-related diseases like hair loss, heart disease, cancer, and dementia may be unintended consequences of mechanisms that engender human survival to protect against episodic vitamin and mineral shortages.
Such deficiencies would decay all "non-essential systems" but allow critical metabolic functions, such as ATP production, intact," explained Prof Ames in the Proceedings of the National Academy of Sciences.
Professor Ames is also a senior scientist at Children's Hospital Oakland Research Institute (CHORI).
