Document Summary
Nufs 356 nutrition requirements for the elderly. Cross-sectional studies: a snapshot to the whole population at one point in time. Limitations include higher non-response rates in higher ages, people with unhealthy habits die sooner and we have bias and the many factors that determine food habits. Longitudinal studies: same group of people over time. Limitations include change in technology, in recommendations and the cognitive ability of the participants. Cross sectional studies show that more older individuals eat enough fruit and veggies but as they age they consume less dairy and grain products. The reduction of these food groups is concerning because of the vitamins that they provide.

Longitudinal studies of people"s average kcal/kg of body weight give us some insight into the changing requirements of aging.
