Plain language summary
The body composition of postmenopausal women changes rapidly due to hormonal changes, including the loss of bone (osteoporosis) and muscle (sarcopenia), usually in the presence of increased adiposity and fat redistribution towards central-type obesity. The aim of this study was to summarise the efficacy of soy foods and their impact on body composition. Research shows that soy products: - may improve the body composition of menopausal and premenopausal women. - delay the physical disabilities of menopausal women with osteosarcopenia and obesity. - may improve muscle mass and bone strength to prevent the development of osteosarcopenia in post-menopausal women. Authors conclude that further research is required since some studies have questioned the mechanism of the protective effect of soybean ingredients on certain metabolic diseases.
Abstract
Chronic diseases in postmenopausal women are caused by rapid changes in hormones and are accompanied by rapid changes in body composition (muscle, bone, and fat). In an aging society, the health of postmenopausal women is a social issue, and people's interest in ingesting high-quality protein is increasing in order to maintain a healthy body composition. This review aims to summarize the efficacy of soy foods and their impact on body composition. The soy protein and isoflavones contained in soy foods can improve muscle and bone density quality and reduce body weight. It is considered a breakthrough in preventing osteosarcopenia and obesity that may occur after menopause.

Abstract
There are many studies investigating nutritional factors that affect both sarcopenia and muscle formation. According to extensive research, protein has an essential role in muscle formation. More recently, vitamin D has emerged as an important factor that regulates muscle metabolism. However, studies and research of association between 25-Hydroxyvitamin D (25(OH)D) status and components of homeostasis model assessment of insulin resistance (HOMA-IR) in older are limited. Nineteen studies were found through a search of electronic databases and were subjected to a meta-analysis to investigate the differences in serum levels of 25(OH)D and HOMA-IR between patients with controls and sarcopenia. The random-effects standardized mean difference (SD) and 95% confidence interval (CI) were calculated as the effect size. Nineteen studies with 19,528 participants (5,081 with sarcopenia and 14,447 without) were analyzed. Sarcopenic participants had significantly lower serum levels of 25(OH)D (SD =1.163; 95% CI 0.514, 1.812; p<0.001; I2=99.652%) and HOMA-IR (SD=-2.040; 95% CI -3.376, -0.705; p<0.005; I2=99.837%) than controls. It has been reiterated that sarcopenia may be related serum levels of 25(OH)D and HOMA-IR. This relationship needs to be clarified by future longitudinal studies.

Advantage of Dairy for Improving Aging Muscle.

Journal of obesity & metabolic syndrome. 2019;(3):167-174
Abstract
The risk of sarcopenia increases with aging. Malnutrition in the elderly population is an important risk factor for sarcopenia. Calcium (Ca), phosphate (P), vitamin D and protein are key nutrients for the human body and affect muscle mass and quality. Dairy products are rich in these nutrients, which implicates that dairy products might be ideal for elderly population. This systematic review highlights the effects of dairy products on muscle mass, muscle strength and body performance in the elderly population in the perspective of Ca, P, vitamin D and protein.
