Definition. Food loss and waste occurs at all stages of the food supply chain – production, processing, sales, and consumption. [13][12] Definitions of what constitutes food loss versus food waste or what parts of foods (i.e., inedible parts) exit the food supply chain are considered lost or wasted vary. [12]
Evolutionary biologists have developed various theoretical models to explain the evolution of food-sharing behavior—" [d]efined as the unresisted transfer of food" from one food-motivated individual to another [1] — among humans [2][3][4][5] and other animals. [6][7][8] Models of food-sharing are based upon general evolutionary theory.
Social aspects. v. t. e. Set point theory, as it pertains to human body weight, states that there is a biological control method in humans that actively regulates weight towards a predetermined set weight for each individual. [1] This may occur through regulation of energy intake (e.g.via increased or decreased appetite) or energy expenditure ...
Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...
Function: To find food and avoid danger. Phylogeny: The vertebrate eye initially developed with a blind spot, but the lack of adaptive intermediate forms prevented the loss of the blind spot. Mechanism: The lens of the eye focuses light on the retina. Development: Neurons need the stimulation of light to wire the eye to the brain (Moore, 2001: ...
Psychology. Food psychology is the psychological study of how people choose the food they eat (food choice), along with food and eating behaviors. [1] Food psychology is an applied psychology, using existing psychological methods and findings to understand food choice and eating behaviors. [2] Factors studied by food psychology include food ...
Psychology. Environmental psychology is a branch of psychology that explores the relationship between humans and the external world. [1] It examines the way in which the natural environment and our built environments shape us as individuals. Environmental psychology investigates how humans change the environment and how the environment ...
Behavioral neuroscience, also known as biological psychology, [1] biopsychology, or psychobiology, [2] is part of the broad, interdisciplinary field of neuroscience, with its primary focus being on the biological and neural mechanisms underlying behavior. Cognitive neuroscience is similar to behavioral neuroscience, in that both fields study ...
