The study of human eating behavior is carried out by researchers in various disciplines, since eating fulfils biological needs, but is also a source of pleasure and comfort, and reflects economic, social and cultural realities and perceptions. While clearly the biological drives of feeding, hunger and satiety have shared physiological bases with other mammals, including the primates, a central issue to the understanding of human eating is the characterization of specific human feeding traits, which are novel or distinct from those of other mammals.
When you try to understand the human eating diversity remember that humans raised within given cultural and social norms prefer customary foods and flavor combinations; however, within any socio-cultural context,different individuals may display varied likes and dislikes for particular foods.
