Abstract

Body composition changes as people get older. One of the noteworthy alterations is the reduction in total body protein. A decrease in skeletal muscle is the most noticeable manifestation of this change but there is also a reduction in other physiologic proteins such as organ tissue, blood components, and immune bodies as well as declines in total body potassium and water. This contributes to impaired wound healing, loss of skin elasticity, and an inability to fight infection. The recommended dietary allowance (RDA) for adults for protein is 0.8 grams of protein per kilogram of body weight. Protein tissue accounts for 30% of whole-body protein turnover but that rate declines to 20% or less by age 70. The result of this phenomenon is that older adults require more protein/kilogram body weight than do younger adults. Recently, it has become clear that the requirement for exogenous protein is at least 1.0 gram/kilogram body weight. Adequate dietary intake of protein may be more difficult for older adults to obtain. Dietary animal protein is the primary source of high biological value protein, iron, vitamin B(12), folic acid, biotin and other essential nutrients. In fact, egg protein is the standard against which all other proteins are compared. Compared to other high-quality protein sources like meat, poultry and seafood, eggs are the least expensive. The importance of dietary protein cannot be underestimated in the diets of older adults; inadequate protein intake contributes to a decrease in reserve capacity, increased skin fragility, decreased immune function, poorer healing, and longer recuperation from illness.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
