There is an ongoing debate about the differences in nutritional quality and adequacy of protein from vegan, vegetarian and animal sources, though many studies and institutions have found that a well-planned vegan or vegetarian diet contains enough high-quality protein to support the protein requirements of both sedentary and active people at ...
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. [11] [12] Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form. [13] Malnutrition is a category of diseases that includes undernutrition and ...
Children who are undernourished before age two and gain weight quickly later in childhood and in adolescence are at high risk of chronic diseases related to nutrition. [14] Studies have found a strong association between undernutrition and child mortality. [15] Once malnutrition is treated, adequate growth is an indication of health and ...
The low protein theory, which relies heavily upon Starling's theory for the movement of fluid in biological systems, provided a compelling rationale for the pathogenesis of edema in kwashiorkor. What it does not explain, however, is the entire array of disturbances that define the kwashiorkor syndrome.
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
The fetal origins hypothesis (differentiated from the Developmental Origins of Health and Disease hypothesis, which emphasizes environmental conditions both before and immediately after birth) proposes that the period of gestation has significant impacts on the developmental health and wellbeing outcomes for an individual ranging from infancy to adulthood.
Starvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. It is the most extreme form of malnutrition. In humans, prolonged starvation can cause permanent organ damage [1] and eventually, death. The term inanition [2] refers to the symptoms and effects of starvation.
A theory of epidemiological transition aimed at explaining not just describing changes in population disease and mortality profiles would need to encompass the role in different morbid conditions of infectious diseases contracted over the life course.
