Plain language summary
Osteoporosis, a progressive systematic skeletal disease is caused by diminished bone density and strength, which may increase the risk of fragility fractures in the spine, pelvis, femur etc. Women are at greater risk of developing osteoporosis. Osteopenia is an intermediary stage of reduced bone mineral density before progressing into the osteoporosis disease state. Exercise and pharmacological therapies are considered two effective strategies commonly used in the treatment of osteoporosis. Exercise may help to improve bone mineral density, strength and muscle mass and reduce the risk of fractures. This systematic review and meta-analysis of five parallel-arm randomised controlled trials investigated the combined effect of exercise and pharmacological therapy on bone mineral density, bone turnover markers, fractures and fracture healing in patients with osteopenia and osteoporosis. This systematic review and meta-analysis showed a non-significant improvement in bone mineral density in patients with osteopenia and osteoporosis followed by combined pharmacological treatment with exercise. Pharmacological therapy alone showed improvement and maintenance of bone mineral density. There was no evidence for the improvement in fragility fracture healing. Due to the low evidence and high heterogeneity of included studies, further robust studies are required to evaluate the combined effect of exercise and pharmacological therapy in people with systematic skeletal disease. Healthcare professionals can use this study to understand the benefits of pharmacological therapy in improving osteoporosis and osteopenia and the potential of adding exercise as a therapeutic strategy in clinical practice.
Abstract
This prospectively registered systematic review and meta-analysis examines whether exercise (EX) training has an additive effect to osteoanabolic and/or antiresorptive pharmacological therapy (PT) in people with osteoporosis on bone mineral density (BMD), bone turnover markers (BTMs), fracture healing, and fractures. Four databases (inception to 6 May 2022), 5 trial registries, and reference lists were searched. Included were randomized controlled trials comparing the effect of EX + PT vs. PT with regard to BMD, BTM, fracture healing, and fractures. Risk of bias was assessed using the Cochrane RoB2 and certainty of evidence by the GRADE approach. Random-effects meta-analysis with Hartung-Knapp-Sidik-Jonkman adjustment was used to estimate standardized mean differences and 95% confidence intervals. Out of 2593 records, five RCTs with 530 participants were included. Meta-analysis showed with very low certainty evidence and wide confidence intervals that EX + PT compared to PT had larger effect sizes for BMD at 12 months at the hip (SMD [95%CI]: 0.18 [- 1.71; 2.06], n = 3 studies), tibia (0.25 [- 4.85; 5.34], n = 2), lumbar spine (0.20 [- 1.15; 1.55], n = 4), and forearm (0.05 [- 0.35; 0.46], n = 3), but not femoral neck (- 0.03 [- 1.80; 1.75], n = 3). Furthermore, no improvement was revealed for BTM such as bone ALP (- 0.68 [- 5.88; 4.53], n = 3), PINP (- 0.74 [- 10.42; 8.93], n = 2), and CTX-I (- 0.69 [- 9.61; 8.23], n = 2), but with very wide confidence intervals. Three potentially relevant ongoing trials were identified via registries. No data were found for fracture healing or fracture outcomes. It remains unclear whether EX has an additive impact to PT in people with osteoporosis. High-quality, adequately powered, targetted RCTs are required. PROTOCOL REGISTRATION PROSPERO CRD42022336132.

Plain language summary
Osteoporosis is associated with severe complications, such as osteoporotic fracture and fracture-related functional disability. Risk factors for osteoporosis must be identified and validated at the earliest. The aim of this study was to investigate the association of coffee and tea intake with bone mass density (BMD) and hip fracture risk. This study was a systematic review and meta-analysis of 106 studies. In total, 416,847 individuals (BMD related studies, 99,750 individuals; hip fracture–related studies, 408,562 individuals) were included in the final analysis. Results showed that the daily intake of caffeinated beverages, such as coffee and tea, is not associated with BMD or hip fracture risk, particularly in postmenopausal women. Authors concluded that their findings help reduce the inconsistency in the current literature. Furthermore, it may serve as a reference for future studies aimed at identifying the risk factor for osteoporosis.
Abstract
Background and Objectives: Osteoporosis is characterized by low bone mass and high bone fragility. Findings regarding the association of coffee and tea intake with osteoporosis have been inconsistent. We conducted this meta-analysis to investigate whether coffee and tea intake is associated with low bone mineral density (BMD) and high hip fracture risk. Materials and Methods: PubMed, MEDLINE, and Embase were searched for relevant studies published before 2022. Studies on the effects of coffee/tea intake on hip fracture/BMD were included in our meta-analysis, whereas those focusing on specific disease groups and those with no relevant coffee/tea intake data were excluded. We assessed mean difference (MD; for BMD) and pooled hazard ratio (HR; for hip fracture) values with 95% confidence interval (CI) values. The cohort was divided into high- and low-intake groups considering the thresholds of 1 and 2 cups/day for tea and coffee, respectively. Results: Our meta-analysis included 20 studies comprising 508,312 individuals. The pooled MD was 0.020 for coffee (95% CI, -0.003 to 0.044) and 0.039 for tea (95% CI, -0.012 to 0.09), whereas the pooled HR was 1.008 for coffee (95% CI, 0.760 to 1.337) and 0.93 for tea (95% CI, 0.84 to 1.03). Conclusions: Our meta-analysis results suggest that daily coffee or tea consumption is not associated with BMD or hip fracture risk.

Plain language summary
Menopause is the permanent cessation of menstrual cycles following the loss of ovarian follicular activity. It is associated with increased prevalence of obesity, metabolic syndrome, cardiovascular disease, and osteoporosis. The aim of this narrative review was to discuss the current evidence on the association between dietary patterns and clinical endpoints in postmenopausal women (body composition, bone mass, and risk markers for cardiovascular disease), and thereby providing novel insight into the establishment of optimal dietary guidelines for healthy postmenopausal period. Research shows that: - the changes in weight and fat distribution in women are associated with aging and mainly with the decrease in oestradiol levels during peri- and post-menopause. - calcium, vitamin D, vitamin K, selenium, magnesium, and beta-carotene adequate intake could be linked with better BMD in postmenopausal women. - diet is a major modifiable risk factor for cardiovascular disease and could be a powerful intervention to reduce cardiovascular risks in postmenopausal women. - the Mediterranean diet is composed of healthy foods that have anti-inflammatory and antioxidant properties. Authors indicate that future studies evaluating the effects of low-fat, plant-based diets on fat mass in post-menopausal women are needed.
Abstract
Among the various aspects of health promotion and lifestyle adaptation to the postmenopausal period, nutritional habits are essential because they concern all women, can be modified, and impact both longevity and quality of life. In this narrative review, we discuss the current evidence on the association between dietary patterns and clinical endpoints in postmenopausal women, such as body composition, bone mass, and risk markers for cardiovascular disease. Current evidence suggests that low-fat, plant-based diets are associated with beneficial effects on body composition, but further studies are needed to confirm these results in postmenopausal women. The Mediterranean diet pattern along with other healthy habits may help the primary prevention of bone, metabolic, and cardiovascular diseases in the postmenopausal period. It consists on the use of healthy foods that have anti-inflammatory and antioxidant properties, and is associated with a small but significant decrease in blood pressure, reduction of fat mass, and improvement in cholesterol levels. These effects remain to be evaluated over a longer period of time, with the assessment of hard outcomes such as bone fractures, diabetes, and coronary ischemia.

Plain language summary
Eating habits not only affect current health but may determine the development of future diseases in later stages of life. The appearance of genomics has presented an opportunity to explore the inter-individual differences in the metabolism of and response to nutrients. Nutraceuticals are biological substances extracted from natural sources by non-denaturing processes to preserve their original properties without any chemical manipulation. Thus, non-denaturation conditions and the use of the original matrix of the species allow all health-beneficial properties to remain intact. This review outlines that: - fish occupies the highest position in marine animal consumption. Literature shows strong links between fish and seafood consumption and positive health effects, particularly in a decreased risk of coronary heart and cardiovascular diseases, a decrease in inflammatory diseases such as arthritis, and the prevention of cancer. - the consumption of complex marine extracts provides numerous health benefits concerning the immune system, hypertension, atherosclerosis, arthritis, and menopause-related dysfunctions, and might reduce the risk of cardiovascular problems, osteoporosis, or senile muscle weakness. - based on nutrigenomic and epigenomic principles, nutritional advice can benefit the relationship between genes and the nutritional habit-related consequences. Authors conclude that the use of each person’s genetic profile for the prescription of nutraceuticals is a major goal to be striven for in order to improve their effectiveness in the prevention and natural treatment of prevalent diseases.
Abstract
The investigation of new alternatives for disease prevention through the application of findings from dietary and food biotechnology is an ongoing challenge for the scientific community. New nutritional trends and the need to meet social and health demands have inspired the concept of functional foods and nutraceuticals which, in addition to their overall nutritional value, present certain properties for the maintenance of health. However, these effects are not universal. Nutrigenetics describes how the genetic profile has an impact on the response of the body to bioactive food components by influencing their absorption, metabolism, and site of action. The EbioSea Program, for biomarine prospection, and the Blue Butterfly Program, for the screening of vegetable-derived bioproducts, have identified a new series of nutraceuticals, devoid of side effects at conventional doses, with genotype-dependent preventive and therapeutic activity. Nutrigenomics and nutrigenetics provide the opportunity to explore the inter-individual differences in the metabolism of and response to nutrients, achieving optimal results. This fact leads to the concept of personalized nutrition as opposed to public health nutrition. Consequently, the development and prescription of nutraceuticals according to the individual genetic profile is essential to improve their effectiveness in the prevention and natural treatment of prevalent diseases.

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.
