Effects of dietary patterns and low protein intake on sarcopenia risk in the very old: The Newcastle 85+ study

A. Granic, N. Mendonça, A.A. Sayer, et al.

Clin Nutr. 2019 Jan 21. pii: S0261-5614(19)30011-1. doi: 10.1016/j.clnu.2019.01.009. [Epub ahead of print]

The aim was to investigate the association between healthy dietary patterns DPs and the risk of sarcopenia over 3 years, and to determine whether protein intake influences this relationship in community-dwelling older adults from the Newcastle 85 + Study.

Higher protein intake is associated with a lower likelihood of frailty among older women, Kuopio OSTPRE-Fracture Prevention Study

M. Isanejad, J. Sirola, T. Rikkonen, et al.

Eur J Nutr. 2019 May 7. doi: 10.1007/s00394-019-01978-7. [Epub ahead of print]

Nordic nutrition recommendations (2012) suggest protein intake ≥ 1.1 g/kg body weight (BW) to preserve physical function in Nordic older adults. However, no published study has used this cut-off to evaluate the association between protein intake and frailty. This study examined associations between protein intake, and sources of protein intake, with frailty status at the 3-year follow-up.

Nutrient-rich, high-quality, protein-containing dairy foods in combination with exercise in aging persons to mitigate sarcopenia

S.M. Phillips, W. Martinson

Nutr Rev. 2019;77(4):216-229

This narrative review provides evidence to support a recommendation for per-meal protein targets in older persons that are underpinned by knowledge of muscle protein turnover.

Associations between dietary patterns at age 71 and the prevalence of sarcopenia 16 years later

M. Karlsson, W. Becker, K. Michaëlsson, et al.

Clin Nutr. 2019 Apr 18. pii: S0261-5614(19)30182-7. doi: 10.1016/j.clnu.2019.04.009. [Epub ahead of print]

The growing recognition of the significance of sarcopenia has highlighted the need to understand etiologic factors, where food intake likely plays a role. The aim was to investigate the association between dietary patterns at mean age 71 and the prevalence of sarcopenia at mean age 87 in a Swedish cohort of community dwelling men.

Effect of nutritional supplementations on physical performance and muscle strength parameters in older people: A systematic review and meta-analysis

N .Veronese, B. Stubbs, L. Punzi, et al.

Ageing Res Rev. 2019;51:48-54

Malnutrition plays a role in the development of poor physical performance, frailty and sarcopenia. The use of nutritional supplementations for improving physical performance and muscle strength parameters in older people is unclear. We therefore aimed to summarize the effect of nutritional supplementations compared to placebo on physical performance (i.e. tests more investigating physical function, utilising aerobic capacity & muscle power) and muscle strength (i.e. tests depending on muscle power) outcomes in older people in randomized controlled trials (RCTs).

Thirteen weeks of supplementation of vitamin D and leucine-enriched whey protein nutritional supplement attenuates chronic low-grade inflammation in sarcopenic older adults: the PROVIDE study

K. Liberman, R. Njemini, Y. Luiking, et al.

Aging Clin Exp Res. 2019 May 2. doi: 10.1007/s40520-019-01208-4. [Epub ahead of print]

A chronic low-grade inflammatory profile (CLIP) is associated with sarcopenia in older adults. Protein and Vitamin (Vit)D have immune-modulatory potential, but evidence for effects of nutritional supplementation on CLIP is limited. The aim was to investigate whether 13 weeks of nutritional supplementation of VitD and leucine-enriched whey protein affected CLIP in subjects enrolled in the PROVIDE-study, as a secondary analysis.
