Nutrients have been recognized as essential for maximum growth, successful reproduction, and infection prevention since the 1940s; since that time, the lion's share of nutrient research has focused on defining their role in these processes.

Nutrients have been recognized as essential for maximum growth, successful reproduction, and infection prevention since the 1940s; since that time, the lion's share of nutrient research has focused on defining their role in these processes. Around 1990, however, a major shift began in the way that researchers viewed some nutrients particularly the vitamins. This shift was motivated by the discovery that modest declines in vitamin nutritional status are associated with an increased risk of ill-health and disease (such as neural tube defects, heart disease, and cancer), especially in those populations or individuals who are genetically predisposed. In an effort to expand upon this new understanding of nutrient action, nutritionists are increasingly turning their focus to the mathematical modeling of nutrient kinetic data. The availability of suitably-tagged (isotope) nutrients (such as B-carotene, vitamin A, folate, among others), sensitive analytical methods to trace them in humans (mass spectrometry and accelerator mass spectrometry), and powerful software (capable of solving and manipulating differential equations efficiently and accurately), has allowed researchers to construct mathematical models aimed at characterizing the dynamic and kinetic behavior of key nutrients in vivo in humans at an unparalleled level of detail.

Autorenporträt
Hans-Georg Müller wurde am 27.August 1937 in Suhl in Thüringen geboren. Nach dem Abitur 1955 verließ er die DDR und studierte an den Unis Göttingen und Grenoble in Frankreich Mathematik, Physik, Philosophie, Pädagogik und Französisch. Nach jahrzehntelanger Arbeit in der Datenverarbeitung in Sindelfingen, Böblingen und Stuttgart nahm er nach seiner Pensionierung 1996 an der Uni Tübingen ein Zweitstudium der Allgemeinen und Vergleichenden Sprachwissenschaft und der Islamkunde auf, das er 2001 mit dem Magister Artium und 2003 mit der Promotion abschloss.
