"The assumption from life history theory based on the assumption of calories as an universal measure of nutrients that puberty must be a linear sequence of events and that hallmarks of puberty happening in a different order than population average is classified as pathology imposes particular problems for healthy eating in adolescents that sometimes extend into young adulthood, especially for those who retain into adulthood visible signs of having gone through a different sequence of puberty. Research on deficiencies of essential nutrients show that deficiencies of specific nutrients impair different bodily functions and the development thereof depends on which nutrient it is. Some scientists therefore argue that a population in which unhealthy diets such as Western pattern diets impose too much calories at the same time as deficiencies of some micronutrients lead the assumption of the population average sequence of puberty hallmarks being the only "correct" one to falsely classify sequences resulting from a healthy diet as pathology, due to different effects of different nutrients on different aspects of puberty. These scientists argue that measures of health risks such as diabetes and precursor disruptions of metabolism, cell changes known to be precursors of cancer and early stage arteriosclerosis should be used as measures of what diet effects are healthy for youths and that correspondence of their puberty sequence to a population average should be regarded as irrelevant. It is argued that the persistence of simplistic caloric models of nutrition in life history theory and related disciplines are due to academic insularity that cause them to miss out on research on micronutrient deficiencies (examples mentioned are that optimal foraging theory misses the necessity of essential nutrients and that the assumption of an universal sex division of costs of reproduction miss the differences in costs for different nutrients and therefore different body functions that need them across the world depending on what nutrient is locally the most scarce) and that the effects are harmful due to prescriptions of unhealthy diets and in some cases harmful hormone therapy to adolescents and young adults whose "pathology" is simply health resulting from a healthy diet.
