men have 14% less leg muscle than do those aged 20, and older adults will lose 0.7% to 0.8% of muscle per year. Longitudinal studies show similar results, suggesting that older women lose 1% of leg muscle mass per year and 0.2% to 0.4% of trunk muscle, with...
RESULTS: The mean estimated average requirement (EAR) and upper 95% CI (approximating the RDA) protein requirement of women >65 y were 0.96 and 1.29 g · kg(-1) · d(-1), respectively. CONCLUSION: These estimates of protein requirements for older women are higher than the current EAR ...
Only 14% of men over 70 and 4% ofwomenover 70 do not meet their estimated average protein requirements. This could be for many reasons, including a decline in overall health or an illness or injury which leads to reduced appetite, reduced ability to prepare foods for themselves and also th...
It is important to note that protein requirements increase considerably with illness severity. Current clinical practice guidelines recommend giving patients with mild to moderate illness 0.8 to 1.2 g/kg protein per day, and to prescribe critically ill patients higher protein diets—1.2 to 1.5 g/kg...
Protein requirements by age: The National Academy of Medicine recommends that adults get about 0.8 grams of protein a day for every kilogram they weigh. That's about 7 grams for every 20 pounds. It suggests babies and children get a bit more, ranging from 1.2 grams per kilogram for infants...

Descriptive statistics were conducted to describe the content of nutrients, environmental impact, and quantities of food groups of the mean HAB and modeled diets (PROT, +PROT, and +PROT-GHGE diets) for older men and women separately. To assess the acceptability of the modeled diets, departure ...
These limitations underscore the challenges of determining protein intake requirements for all adults, as well as the difficulty in differentiating needs for men versus women or for older adults versus younger adults.32 Although other methods, including carbon balance34 and amino acid indicator studies,...
During the mid-luteal phase, protein requirements may be higher due to an increase in protein oxidation. During exercise in the mid-luteal phase, protein usage appears to be higher. More protein is used for building endometrial tissue in the mid-luteal phase. ...
When protein intake is in excess of requirements, the con-stituent amino acids must be catabolized and the waste products excreted. This is associated with the production of acid equiva-lents as well as the build-up of urea and possibly other (as yet poorly characterized) metabolic toxins. ...
