Abstract: Better understanding the complex factors leading to human diseases will be necessary for both long term prevention and for managing short-term crises health problems. The underlying context is one with finite global resources for sustained healthy human survival, population explosion, increased environmental pollution, decreased clean air, water, food distribution, diminishing opportunities for human self-esteem, increased median life span, and interconnected causes of acute infectious and chronic diseases.  The transition of our pre-human nutritional requirements for survival to our current unequal and culturally-shaped diet has created a biologically mismatched human dietary experience. While individual genetic, gender, and developmental stage factors contribute to human diseases, various environmental and culturally-determined factors are now contributing to both acute and chronic diseases. The transition from the hunter-gatherer to an agricultural-dependent human being has brought about a global crisis in human health.  Initially, early humans ate seasonally-dependent and calorically-restricted foods, during the day, in a “feast or famine” manner. Today,  modern humans eat diets of  caloric abundance, at all times of the day, with foods of all seasons and from all parts of the world, that have been processed and which have been contaminated by all kinds of factors. No longer can one view as distinct, infectious agent–related human acute diseases from chronic diseases. A new concept has emerged that indicates pre-natal maternal dietary exposures can now affect diseases later in life (Barker hypothesis).  Examples from the studies of the atomic bomb survivors illustrate this insight.
