INTRODUCTION. Absorption of minerals, vitamins, drugs or food is a complex process. It can be generalized as passive absorption via a paracellular pathway, facilitated transport through membranes via transporters and active energy consuming transport mechanisms (1, 2). In the case of facilitated and active transport,
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and health.Poor nutrition is a chronic problem often linked to poverty, food security or a poor understanding of nutrition and dietary practices.

Streak is a more reliable property than color because streak does not vary. Minerals that are the same color may have a different colored streak. Many minerals, such as the quartz in the Figure above, do not have streak. To check streak, scrape the mineral across an unglazed porcelain plate (Figure below). Yellow gold pyrite has a blackish streak, another indicator that pyrite is not gold, which has a golden

Figure 1 Physics of X ray fluorescence in a schematic representation. When materials are exposed to short wavelength X rays or to gamma rays, ionization of their component atoms may take place. Ionization consists of the ejection of one or more electrons from the atom, and may occur if the atom is exposed to radiation with an energy greater than its ionization energy .
