Dihydrodaidzein and 6-hydroxydaidzein mediate the fermentation-induced increase of antiosteoporotic effect of soybeans in ovariectomized mice.

The consumption of soybeans is known to have beneficial effects on osteoporosis in postmenopausal women. However, the effects of soybean fermentation on the bioavailability and the antiosteoporotic effect have not yet been elucidated. To address this question, we fed ovariectomized C57BL/6J mice with a 5% nonfermented raw soybean (RS)- or fermented soybean (FS)-supplemented diet. After 18 wk of treatment, microcomputed tomography showed that FSs significantly increased bone mineral density compared with RSs. This was because of the up-regulation of bone morphogenic protein 2 (Bmp2) and its downstream target osteopontin in bone tissues. We analyzed isoflavone metabolite profiles in the sera of RS- or FS-fed mice and observed that the levels of 19 isoflavone metabolites were significantly increased in the sera of FS-fed mice. Among these metabolites, we observed that both dihydrodaidzein (DHD) and 6-hydroxydaidzein (6-HD) increased osteogenesis via Bmp2 signaling pathway in MC3T3-E1 cells and reduced receptor activator of nuclear factor κ-B ligand-induced osteoclastogenesis in RAW264.7 cells through the inhibition of NF-κB activation and MAPK phosphorylation. These data suggest that improved bioavailability of FSs resulted from the production of active metabolites such as DHD and 6-HD after consumption. DHD and 6-HD can be used as potential therapeutics for the amelioration of osteoporotic bone loss.-Kim, J.-S., Lee, H., Nirmala, F. S., Jung, C. H., Kim, M. J., Jang, Y.-J., Ha, T. Y., Ahn, J. Dihydrodaidzein and 6-hydroxydaidzein mediate the fermentation-induced increase of anti-osteoporotic effect of soybeans in ovariectomized mice.

Is a 'healthy diet' and a 'calcium-rich diet' the same thing? Qualitative study examining perceptions of a calcium-rich diet in individuals who have received bone health education.

BACKGROUND: In the present study, we aimed to (i) examine perceptions of achieving calcium and vitamin D recommended dietary allowance (RDA) and (ii) determine how participants talked about food in relation to RDA recommendations. METHODS: Participants aged ≥50 years who were prescribed osteoporosis medication and received two modes of bone health education were eligible. Relying on a qualitative description design, we interviewed participants 1 month after they had attended an education session and received a self-management booklet. Calcium and vitamin D intakes were estimated by in-depth questions about diet and supplements and compared with perceptions of achieved RDA levels. Interview transcripts were analysed based on an analytic hierarchical process. RESULTS: Forty-five participants (29 reporting previous fragility fractures) were included. Calcium and vitamin D RDA appeared to be potentially achieved by 64% and 93% of participants, respectively, primarily because of reliance on supplements. Few participants talked about vitamin D in relation to food intake and 49% of participants were unclear about the calcium content of food. Most considered that a healthy diet was equivalent to a calcium-rich diet. We noted no differences in our findings in the subset of individuals with fragility fractures. CONCLUSIONS: Despite reporting a prescription for osteoporosis medication and receiving bone health education, a substantial number of individuals appeared to have sub-optimal calcium levels. This may be attributed to the challenge of achieving RDA with diet alone and the misconception of a healthy diet as a calcium-rich diet.

Short communication: Dietary bovine milk-derived exosomes improve bone health in an osteoporosis-induced mouse model.

Osteoporosis is a systemic skeletal disease characterized by low bone mass and micro-architectural deterioration of bone tissue, with a consequent increase in bone fragility and fracture susceptibility. In an aged society with increased life expectancy, the incidence rate of osteoporosis is also rapidly increasing. Inadequate nutrition may negatively influence bone metabolism. Recently, many studies have investigated the functionality of milk-derived exosomes, which play important roles in cell-to-cell communication. However, there are few reports of how milk-derived exosomes influence osteoblast proliferation and differentiation. Here, we determined whether bovine colostrum-derived exosomes promote anti-osteoporosis in vitro and in vivo. Tartrate-resistant acid phosphatase-stained cells were significantly inhibited in Raw264.7 cells treated with exosomes, indicating reduced osteoclast differentiation. We induced osteoporosis in mice using glucocorticoid pellets after orally administering exosomes for 2 mo. Interestingly, the bone mineral density of exosome-fed mouse groups was significantly improved compared with the glucocorticoid-induced osteoporosis group without exosome treatment. In addition, Lactobacillus were decreased in the gut microbiota community of osteoporosis-induced mice, but the gut microbiota community composition was effectively restored by exosome intake. Taken together, we propose that exosomes isolated from bovine colostrum could be a potential candidate for osteoporosis prevention, bone remodeling improvement, and inhibition of bone resorption. To our knowledge, this is the first time that a protective effect of milk exosomes against osteoporosis has been demonstrated in vivo. Our results strongly suggest that bovine colostrum exosomes might be used as a prophylaxis to prevent the onset of osteoporosis. Indeed, our results offer promising alternative strategies in the nutritional management of age-related bone complications.

Tanshinone prevents alveolar bone loss in ovariectomized osteoporosis rats by up-regulating phosphoglycerate dehydrogenase.

Osteoporosis is manifested by reduced bone mass. Tanshinone has been shown to affect osteoclast differentiation, but its role in osteoporosis remains less clear. This study aimed to investigate the effects and molecular mechanisms of tanshinone on osteoporosis. Osteoporosis was induced by bilateral ovariectomy (OVX) in adult female rats treated with or without tanshinone. Trabecular bone structure was assessed by micro-computed tomography (micro-CT). Bone marrow stromal cells (BMSCs) were isolated for analysis of stemness and senescence. mRNA levels of age related genes were examined and the role of the gene that was upregulated by tanshinone treatment was suppressed to determine its involvement in tanshinone mediated effects. Finally, the mechanism underlying tanshinone induced gene upregulation was explored. We found that tanshinone treatment restored alveolar bone structure in OVX rats as well as the stemness and senescence status of BMSCs isolated from OVX rats. Tanshinone upregulated Phgdh mRNA levels and inhibition of phosphoglycerate dehydrogenase Phgdh, the protein encoded by the Phgdh gene, abolished the effects of tanshinone on BMSC stemness and senescence. Finally, we found that OVX lead to hypermethylation of the promoter region of Phgdh which was suppressed by tanshinone treatment. Our study shows that tanshinone potently suppress OVX induced osteoporosis and BMSC senescence through upregulation of PHGDH.

Dietary strategies for mitigating osteosarcopenia in older adults: a narrative review.

The synchronic loss of bone mineral density and decrease in muscle mass, strength, and function defines the scenario of osteosarcopenia, which is associated with an increased risk of falls and fractures in older adults. An important role in preventing muscle and bone loss is played by nutritional factors, in particular the intake of proteins, calcium, magnesium and vitamin D. This review summarizes the available literature concerning the influence of protein intake and supplementation (vitamin D, Ca, Mg, branched-chain amino acids) on the decline of musculoskeletal integrity in healthy older adults. Furthermore, in this paper, we attempted to give some suggestions to build up adequate nutritional and dietary strategies against the age-related loss of muscle and bone mass.

Vitamin D, bone mineral density and risk of fracture in people with intellectual disabilities.

BACKGROUND: People with intellectual disabilities (IDs) have very high rates of osteoporosis and fractures, to which their widespread vitamin D deficiency and other factors could contribute. We aimed to assess in people with IDs previously treated for vitamin D deficiency (1) long-term adherence to vitamin D supplementation and (2) bone mineral density (BMD), as an indicator for risk of fractures, according to vitamin D supplementation and other factors. METHOD: We recorded height, weight, medical, pharmacological, dietary and lifestyle assessment. Blood sample were taken for vitamin D and related analytes. dual-energy X-ray absorptiometry for BMD was performed. RESULTS: Of 51 study participants (mean [standard deviation, SD] age 51.5 [13.6] years, 57% male), 41 (80.4%) were taking vitamin D and 10 were not. Mean [SD] serum vitamin D was 81.3 [21.3] vs. 25.2 [10.2] nmol/L (P < 0.0001), respectively. Thirty-six participants underwent a dual-energy X-ray absorptiometry scan, which showed osteoporosis in 23.7% and osteopenia in 52.6%. Participants on vitamin D had higher BMD than those who were not, a statistically significant difference when confounders (lack of mobility and hypogonadism) were removed. BMD was significantly different according to mobility, particularly in wheelchair users, in whom hip BMD was 33% lower (P < 0.0001) than in participants with normal mobility. Participants still taking vitamin D showed a 6.1% increase in BMD at the spine (P = 0.003) after mean [SD] 7.4 [1.5] years vitamin D treatment. CONCLUSIONS: In people with IDs and previous vitamin D deficiency, BMD increases on long-term vitamin D supplementation. However, additional strategies must be considered for osteoporosis and fracture prevention in this population.

Biofunctional soyasaponin Bb in peanut (Arachis hypogaea L.) sprouts enhances bone morphogenetic protein-2-dependent osteogenic differentiation via activation of runt-related transcription factor 2 in C2C12 cells.

Improvement of bone formation is necessary for successful treatment of the bone defects associated with osteoporosis. In this study, we sought to elucidate the osteogenic activity of peanut sprouts and their bioactive components. We found that peanut sprout water extract (PSWE) enhanced bone morphogenetic protein-2-mediated osteoblast differentiation in a dose-dependent manner by stimulating expression of runt-related transcription factor 2 (Runx2) via activation of AKT/MAP kinases. We identified a major component of PSWE, soyasaponin Bb, as the bioactive compound responsible for improvement of anabolic activity. Soyasaponin Bb from PSWE enhanced expression of the osteogenic transcription factor Runx2 and alkaline phosphatase. The soyasaponin Bb content depended on sprouting time of peanut, and the anabolic action of PSWE was dependent on soyasaponin Bb content. Thus, PSWE and soyasaponin Bb have the potential to protect against bone disorders, including osteoporosis.

Pisidium coreanum Inhibits Multinucleated Osteoclast Formation and Prevents Estrogen-Deficient Osteoporosis.

Mollusks have served as important sources of human food and medicine for a long time. Raw Pisidium coreanum, a freshwater bivalve of the phylum Mollusca, is used in traditional therapies in parts of Asia. However, the therapeutic effects of Pisidium coreanum on bone diseases are not known. We investigated the functional roles of Pisidium coreanum in osteoporotic bone diseases. Pisidium coreanum inhibited the differentiation of bone marrow-derived monocytic cells into mature osteoclasts in vitro. The ovariectomized mice that received oral administration of Pisidium coreanum showed improvements in both trabecular and cortical bones. This preventive activity of Pisidium coreanum against bone loss was due to limited osteoclast maturation with reduced osteoclast surface extent in trabecular bone tissue. The formation of large multinucleated osteoclasts in vitro was significantly decreased in response to Pisidium coreanum, consistent with the reduced expression levels of osteoclast markers and fusion-related genes, such as NFATc1, p65, integrin αvß3, DC-STAMP, OC-STAMP, Atp6v0d2, FAK, CD44, and MFR. These data suggest that Pisidium coreanum inhibits osteoclast differentiation by negatively regulating the fusion of mononuclear osteoclast precursors. Thus, our data demonstrate the ability of Pisidium coreanum to effectively prevent estrogen-deficient osteoporosis through inhibition of multinucleated osteoclast formation.

Biological Activities of Lactose-Based Prebiotics and Symbiosis with Probiotics on Controlling Osteoporosis, Blood-Lipid and Glucose Levels.

Lactose-based prebiotics are synthesized by enzymatic- or microbial- biotransformation of lactose and have unique functional values. In this comprehensive review article, the biochemical mechanisms of controlling osteoporosis, blood-lipid, and glucose levels by lactose-based prebiotics and symbiosis with probiotics are reported along with the results of clinical investigations. Interaction between lactose-based prebiotics and probiotics reduces osteoporosis by (a) transforming insoluble inorganic salts to soluble and increasing their absorption to gut wall; (b) maintaining and protecting mineral absorption surface in the intestine; (c) increasing the expression of calcium-binding proteins in the gut wall; (d) remodeling osteoclasts and osteoblasts formation; (e) releasing bone modulating factors; and (f) degrading mineral complexing phytic acid. Lactose-based prebiotics with probiotics control lipid level in the bloodstream and tissue by (a) suppressing the expressions of lipogenic- genes and enzymes; (b) oxidizing fatty acids in muscle, liver, and adipose tissue; (c) binding cholesterol with cell membrane of probiotics and subsequent assimilation by probiotics; (d) enzymatic-transformations of bile acids; and (e) converting cholesterol to coprostanol and its defecation. Symbiosis of lactose-based prebiotics with probiotics affect plasma glucose level by (a) increasing the synthesis of gut hormones plasma peptide-YY, glucagon-like peptide-1 and glucagon-like peptide-2 from entero-endocrine L-cells; (b) altering glucose assimilation and metabolism; (c) suppressing systematic inflammation; (d) reducing oxidative stress; and (e) producing amino acids. Clinical investigations show that lactose-based prebiotic galacto-oligosaccharide improves mineral absorption and reduces hyperlipidemia. Another lactose-based prebiotic, lactulose, improves mineral absorption, and reduces hyperlipidemia and hyperglycemia. It is expected that this review article will be of benefit to food technologists and medical practitioners.

Public health impact and economic evaluation of vitamin D-fortified dairy products for fracture prevention in France.

The recommended intake of vitamin D-fortified dairy products can substantially decrease the burden of osteoporotic fractures and seems an economically beneficial strategy in the general French population aged over 60 years. INTRODUCTION: This study aims to assess the public health and economic impact of vitamin D-fortified dairy products in the general French population aged over 60 years. METHODS: We estimated the lifetime health impacts expressed in number of fractures prevented, life years gained, and quality-adjusted life years (QALY) gained of the recommended intake of dairy products in the general French population over 60 years for 1 year (2015). A validated microsimulation model was used to simulate three age cohorts for both women and men (60-69, 70-79, and >80 years). The incremental cost per QALY gained of vitamin D-fortified dairy products compared to the absence of appropriate intake was estimated in different populations, assuming the cost of two dairy products per day in base case. RESULTS: The total lifetime number of fractures decreased by 64,932 for the recommended intake of dairy products in the general population over 60 years, of which 46,472 and 18,460 occurred in women and men, respectively. In particular, 15,087 and 4413 hip fractures could be prevented in women and men. Vitamin D-fortified dairy products also resulted in 32,569 QALYs and 29,169 life years gained. The cost per QALY gained of appropriate dairy intake was estimated at €58,244 and fall below a threshold of €30,000 per QALY gained in women over 70 years and in men over 80 years. CONCLUSION: Vitamin D-fortified dairy products have the potential to substantially reduce the burden of osteoporotic fractures in France and seem an economically beneficial strategy, especially in the general population aged above 70 years.

Vitamin D: Musculoskeletal health.

Perhaps the role of Vitamin D supplementation has been most exhaustively studied in calcium absorption, skeletal wellbeing, muscular potency, balance and risk of falling. Nonetheless, new data has emerged and the recent research on sarcopenia makes the topic increasingly interesting. Given the socioeconomic burden of the musculoskeletal consequences of hypovitaminosis D it is vital to keep abreast with the latest literature in the field. The recommended Vitamin D supplementation dose should suffice to increase the serum 25 hydroxyvitamin D level to 30 ng/mL (75 nmol/L) and this level should be optimally maintained with a maintenance dose, particularly for those diagnosed with osteoporosis.

Food Versus Pharmacy: Assessment of Nutritional and Pharmacological Strategies to Improve Bone Health in Energy-Deficient Exercising Women.

PURPOSE OF REVIEW: The review aims to summarize our current knowledge surrounding treatment strategies aimed at recovery of bone mass in energy-deficient women suffering from the Female Athlete Triad. RECENT FINDINGS: The independent and interactive contributions of energy status versus estrogen status on bone density, geometry, and strength have recently been reported, highlighting the importance of addressing both energy and estrogen in treatment strategies for bone health. This is supported by reports that have identified energy-related features (low body weight and BMI) and estrogen-related features (late age of menarche, oligo/amenorrhea) to be significant risk factors for low bone mineral density and bone stress injury in female athletes and exercising women. Nutritional therapy is the recommended first line of treatment to recover bone mass in energy-deficient female athletes and exercising women. If nutritional therapy fails after 12 months or if fractures or significant worsening in BMD occurs, pharmacological therapy may be considered in the form of transdermal estradiol with cyclic oral progestin (not COC).

[Osteoporosis Liaison Service and nutrition counseling and education.]

Nutritional counseling as part of the Osteoporosis Liaison Service(OLS)should provide active nutritional counseling and lifestyle guidance by referring to the detailed methods for conducting "nutritional status assessments", an item of OLS-7, a detailed activity outcome measure of the OLS. After conducting adequate nutritional assessments, the goals for each stage of behavior change should be established, aiming to set roughly one goal for a specified period of time and increasing the goals once improvements have been made. Incorporating feedback in the next improvement plan becomes very important. Good nutritional counseling will surely lead to achieving the OLS goals(improvement in treatment rates and treatment continuation rates). Moreover, it will contribute to decreasing the number of patients with fractures, eliminating sequential fractures and prolonging a healthy life expectancy in Japan.

Resveratrol supplementation affects bone acquisition and osteoporosis: Pre-clinical evidence toward translational diet therapy.

Osteoporosis is a major public health issue that is expected to rise as the global population ages. Resveratrol (RES) is a plant polyphenol with various anti-aging properties. RES treatment of bone cells results in protective effects, but dose translation from in vitro studies to clinically relevant doses is limited since bioavailability is not taken into account. The aims of this review is to evaluate in vivo evidence for a role of RES supplementation in promoting bone health to reduced osteoporosis risk and potential mechanisms of action. Due to multiple actions on both osteoblasts and osteoclasts, RES has potential to attenuate bone loss resulting from different etiologies and pathologies. Several animal models have investigated the bone protective effects of RES supplementation. Ovariectomized rodent models of rapid bone loss due to estrogen-deficiency reported that RES supplementation improved bone mass and trabecular bone without stimulating other estrogen-sensitive tissues. RES supplementation prior to age-related bone loss was beneficial. The hindlimb unloaded rat model used to investigate bone loss due to mechanical unloading showed RES supplementation attenuated bone loss in old rats, but had inconsistent bone effects in mature rats. In growing rodents, RES increased longitudinal bone growth, but had no other effects on bone. In the absence of human clinical trials, evidence for a role of RES on bone heath relies on evidence generated by animal studies. A better understanding of efficacy, safety, and molecular mechanisms of RES on bone will contribute to the determination of dietary recommendations and therapies to reduce osteoporosis. This article is part of a Special Issue entitled: Resveratol: Challenges in translating pre-clinical findings to improved patient outcomes.

Effects of Dairy Products Consumption on Health: Benefits and Beliefs--A Commentary from the Belgian Bone Club and the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases.

Dairy products provide a package of essential nutrients that is difficult to obtain in low-dairy or dairy-free diets, and for many people it is not possible to achieve recommended daily calcium intakes with a dairy-free diet. Despite the established benefits for bone health, some people avoid dairy in their diet due to beliefs that dairy may be detrimental to health, especially in those with weight management issues, lactose intolerance, osteoarthritis, rheumatoid arthritis, or trying to avoid cardiovascular disease. This review provides information for health professionals to enable them to help their patients make informed decisions about consuming dairy products as part of a balanced diet. There may be a weak association between dairy consumption and a possible small weight reduction, with decreases in fat mass and waist circumference and increases in lean body mass. Lactose intolerant individuals may not need to completely eliminate dairy products from their diet, as both yogurt and hard cheese are well tolerated. Among people with arthritis, there is no evidence for a benefit to avoid dairy consumption. Dairy products do not increase the risk of cardiovascular disease, particularly if low fat. Intake of up to three servings of dairy products per day appears to be safe and may confer a favourable benefit with regard to bone health.

Pregnancy-associated osteoporosis (PAO) with multiple vertebral fragility fractures: diagnosis and treatment in a young primigravid woman.

PAO is an uncommon condition affecting pregnant women during last trimester or early post-delivery period; it is often asymptomatic or presents with pain related to some acute fragility fractures. The diagnosis is often delayed or missed, the etiology remains unknown and no guidelines about treatment have been published. We present one case of PAO in a 33-year-old primigravid woman presenting acute worsening back pain. Our patient was treated with a TLSO brace, oral 25 (OH)-vitamin D supplementation and Teriparatide for 6 months. A short review of the literature has been included and useful advice about how to suspect and diagnose this uncommon disease were given in order to recognize and treat such a debilitating and severe condition for young mothers as best as possible, based on the available scientific evidences.

A community-based cross-sectional study for relationship of frequency of vegetables intake and osteoporosis in a Chinese postmenopausal women sample.

BACKGROUND: The main purpose of this study was to explore the associations between frequency of vegetables intake and osteoporosis (OP) in Chinese postmenopausal women. METHODS: We conducted a large-scale, community-based, cross-sectional study to investigate the associations by using self-report questionnaire to access frequency of vegetables intake. The total of 1903 participants was available to data analysis in this study. Multiple regression models to include frequency of vegetables variable were performed to investigate the relationships for OP, after controlling for confounding factors. RESULTS: Multiple regression analysis indicated that the frequency of vegetables intake was independently and significantly associated with OP (P < 0.1 for model 1 and model 2). The postmenopausal women with high frequency of vegetables intake had a higher prevalence of OP. CONCLUSION: The findings indicated that frequency of vegetables intake was independently and significantly associated with OP. The prevalence of OP was more frequent in Chinese postmenopausal women preferring vegetables food habits. TRIAL REGISTRATION: (ClinicalTrials.gov Identifier: NCT02451397 ; date of registration: 2015-05-28).

[Effects of the nutritional education and dietary intervention on nutritional status and bone mineral density of middle-aged and senile patients with osteoporosis].

OBJECTIVE: To study the effect of the nutritional education and dietary intervention on nutritional status and bone mineral density (BMD) of middle-aged and senile patients with osteoporosis. METHODS: Ninty middle-aged and senile osteoporosis patients were enrolled. They were randomly divided into two groups (intervention and control group) with 45 cases each. The control group was received conventional therapy and the intervention group added with nutritional education and dietary intervention for six months on the basis of conventional therapy. The methods of education and intervention included seminars, brochures distribution, dietary survey and individual guidance. The nutritional status and BMD were analyzed at the beginning and the end of the intervention respectively. RESULTS: After the intervention, the ratios of subjects whose intake of grain, vegetables, fruits, eggs, milk and beans in line with recommended intake of the intervention group were higher than those of the control group (P < 0.05). After the intervention, frequencies of coarse grain, dairy, beans and seafood consumption of the intervention group were higher than those of the control group (P < 0.05). After the intervention, the daily intakes of protein, VA, VC, calcium, zinc, magnesium, dietary fiber of the intervention group were significantly superior to the control group (P < 0.05). BMDs of lumbar spine and femoral neck in the intervention group were significantly higher than those in the control group (P < 0.05). CONCLUSION: The nutritional education and dietary intervention could promote middle-aged and senile patients' reasonable diet, improve their nutritional status, enhance bone mineral density and improve the effect of conventional therapy for osteoporosis.

Association between phosphorus intake and bone health in the NHANES population.

The objective of this study was to estimate the independent associations between intake of phosphorus (P) and bone health parameters such as bone mineral content (BMC) and bone mineral density (BMD). It provides odds ratio (OR) of osteoporosis with quartiles of P intake adjusted for covariates (i.e., age, gender, BMI, and consumption of calcium (Ca), protein, total dairy foods, and vitamin D as well as intakes of supplemental Ca, vitamin D, and multivitamins/minerals). Data came from males and females aged 13-99 years who participated in the 2005-2010 National Health and Nutrition Examination Survey (NHANES). Analyses showed that higher P intake was associated with higher Ca intake, and that dietary Ca:P ratios (0.51-0.62, with a mean of 0.60 for adults) were adequate in all age/gender groups. High intake of P was positively associated with BMC in female teenagers (Q4 vs. Q1: BMC, 30.9 ± 1.1 vs. 29.0 ± 0.5 g, P = 0.001). It was also positively associated with BMC and BMD as well as reduced risk of osteoporosis in adults >20 years of age (Q4 vs. Q1: OR of osteoporosis, 0.55; 95% confidence interval [CI], 0.39- 0.79; P = 0.001; BMC, 37.5 ± 0.4 vs. 36.70 ± 0.3 g, P < 0.01; BMD, 0.986 ± 0.004 vs. 0.966 ± 0.005 g/cm(2), P < 0.05). The data suggest that high intake of P has no adverse effect on bone metabolism in populations with adequate Ca intake, and that it is also associated with positive bone parameters in some age/gender groups.

Focus on Pivotal Role of Dietary Intake (Diet and Supplement) and Blood Levels of Tocopherols and Tocotrienols in Obtaining Successful Aging.

Numerous specific age-related morbidities have been correlated with low intake and serum levels of tocopherols and tocotrienols. We performed a review in order to evaluate the extant evidence regarding: (1) the association between intake and serum levels of tocopherols and tocotrienols and age-related pathologies (osteoporosis, sarcopenia and cognitive impairment); and (2) the optimum diet therapy or supplementation with tocopherols and tocotrienols for the treatment of these abnormalities. This review included 51 eligible studies. The recent literature underlines that, given the detrimental effect of low intake and serum levels of tocopherols and tocotrienols on bone, muscle mass, and cognitive function, a change in the lifestyle must be the cornerstone in the prevention of these specific age-related pathologies related to vitamin E-deficient status. The optimum diet therapy in the elderly for avoiding vitamin E deficiency and its negative correlates, such as high inflammation and oxidation, must aim at achieving specific nutritional goals. These goals must be reached through: accession of the elderly subjects to specific personalized dietary programs aimed at achieving and/or maintaining body weight (avoid malnutrition); increase their intake of food rich in vitamin E, such as derivatives of oily seeds (in particular wheat germ oil), olive oil, hazelnuts, walnuts, almonds, and cereals rich in vitamin E (such as specific rice cultivar rich in tocotrienols) or take vitamin E supplements. In this case, vitamin E can be correctly used in a personalized way either for the outcome from the pathology or to achieve healthy aging and longevity without any adverse effects.
