TLDR
New research and novel research methodologies are necessary to establish the protein needs and optimal patterns of protein intake for older persons.Abstract:
Background.
Protein is a macronutrient essential for growth, muscle function, immunity and overall tissue homeostasis. Suboptimal protein intake can significantly impact physical function and overall health in older adults.read more

TL;DR: For the purposes of optimally managing individuals with physical frailty, all persons older than 70 years and all individuals with significant weight loss (>5%) due to chronic disease should be screened for frailty.

Evidence-Based Recommendations for Optimal Dietary Protein Intake in Older People: A Position Paper From the PROT-AGE Study Group
Juergen M. Bauer,Gianni Biolo,Tommy Cederholm,Matteo Cesari,Alfonso J. Cruz-Jentoft,John E. Morley,Stuart M. Phillips,Cornel C. Sieber,Peter Stehle,Daniel Teta,Renuka Visvanathan,Elena Volpi,Yves Boirie +12 more
TL;DR: To help older people (>65 years) maintain and regain lean body mass and function, the PROT-AGE study group recommends average daily intake at least in the range of 1.2 g protein per kilogram of body weight per day.

Protein intake and exercise for optimal muscle function with aging: recommendations from the ESPEN Expert Group

TL;DR: Recommendations are made that daily physical activity or exercise (resistance training, aerobic exercise) should be undertaken by all older people, for as long as possible to help older adults sustain muscle strength and function into older age.

Protein Ingestion to Stimulate Myofibrillar Protein Synthesis Requires Greater Relative Protein Intakes in Healthy Older Versus Younger Men
Daniel R. Moore,Tyler A. Churchward-Venne,Oliver C. Witard,Leigh Breen,Nicholas A. Burd,Kevin D. Tipton,Stuart M. Phillips +6 more
TL;DR: The data suggest that healthy older men are less sensitive to low protein intakes and require a greater relative protein intake, in a single meal, than young men to maximally stimulate postprandial rates of MPS.

Prevalence, incidence, and clinical impact of sarcopenia: facts, numbers, and epidemiology—update 2014
TL;DR: The definition of sarcopenia is now defined as a decline in walking speed or grip strength associated with low muscle mass, which leads to loss of mobility and function, falls, and mortality.

Nevitt,Marjolein Visser,Stephen B. Kritchevsky,Stefania Badinelli,Tamara B. Harris,Anne B. Newman,Jane A. Cauley,Luigi Ferrucci,Jack M. Guralnik +18 more
TL;DR: In this pooled analysis of individual data from 9 selected cohorts, gait speed was associated with survival in older adults and predicted survival was as accurate as predicted based on age, sex, use of mobility aids, and self-reported function.

TL;DR: Sarcopenia should be considered in all older patients who present with observed declines in physical function, strength, or overall health, and patients who meet these criteria should further undergo body composition assessment using dual energy x-ray absorptiometry with sarcopenia being defined using currently validated definitions.

Anabolic signaling deficits underlie amino acid resistance of wasting, aging muscle

TL;DR: It is demonstrated that EAA stimulate MPS independently of increased insulin availability, and in the elderly, a deficit in MPS in the basal state is unlikely; and the decreased sensitivity and responsiveness of MPS to EAA, associated with decrements in the expression and activation of components of anabolic signaling pathways, are probably major contributors to the failure of muscle maintenance inThe elderly.

TL;DR: Dietary protein may be a modifiable risk factor for sarcopenia in older adults and should be studied further to determine its effects on preserving LM in this population.

TL;DR: It is proposed that the risk of adverse outcomes, such as functional limitation and mortality, is better estimated by considering jointly obesity and muscle strength rather than Obesity and muscle mass and the term ‘sarcopenic obesity’ should be revisited.
