Kumar A, Mahapatra S, Nayak L, Biswal M, Sahoo U, Lal MK, Nayak AK, Pati K. Tuber crops could be a potential food component for lowering starch digestibility and estimated glycemic index in rice. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2024. [PMID: 38953558 DOI: 10.1002/jsfa.13679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Revised: 06/05/2024] [Accepted: 06/09/2024] [Indexed: 07/04/2024]
Abstract
BACKGROUND Rice is considered a high estimated glycemic index (eGI) food because of its higher starch digestibility, which leads to type II diabetes and obesity as a result of a sedentary life style. Furthermore, the incresaing diabetes cases in rice-consuming populations worldwide need alternative methods to reduce the glycemic impact of rice, with dietary prescriptions based on the eGI value of food being an attractive and practical concept. Rice is often paired with vegetables, pulses, tubers and roots, a staple food group in Africa, Latin America and Asia, which are rich in fibre and health-promoting compounds. RESULTS Rice from four categories (high protein, scented, general and pigmented) was analyzed for eGI and resistant starch (RS) content. Among the genotypes, Improved Lalat had the lowest eGI (53.12) with a relatively higher RS content (2.17%), whereas Hue showed the lowest RS (0.19%) with the highest eGI (76.3) value. The addition of tuber crops to rice caused a significant lowering of eGI where the maximum beneficial effect was shown by elephant foot yam (49.37) followed by yam bean (53.07) and taro (54.43). CONCLUSION The present study suggests that combining rice with suitable tuber crops can significantly reduce its eGI value, potentially reducing the burden of diet-associated lifestyle diseases particularly diabetics. © 2024 Society of Chemical Industry.

Abstract
Women face a significant change in their reproductive health as menopause sets in. It is marred with numerous physiological changes that negatively impact their quality of life. This universal, transition phase is associated with menopausal and postmenopausal syndrome, which may spread over 2-10 years. This creates a depletion of female hormones causing physical, mental, sexual and social problems and may, later on, manifest as postmenopausal osteoporosis leading to weak bones, causing fractures and ultimately morbidity and mortality. Menopausal hormone therapy generally encompasses the correction of hormone balance through various pharmacological agents, but the associated side effects often lead to cessation of therapy with poor clinical outcomes. However, it has been noticed that phytotherapeutics is trusted by women for the amelioration of symptoms related to menopause and for improving bone health. This could primarily be due to their reduced side effects and lesser costs. This review attempts to bring forth the suitability of phytotherapeutics/herbals for the management of menopausal, postmenopausal syndrome, and menopausal osteoporosis through several published research. It tries to enlist the available botanicals with their key constituents and mechanism of action for mitigating symptoms associated with menopause as well as osteoporosis. It also includes a list of a few herbal commercial products available for these complications. The article also intends to collate the findings of various clinical trials and patents available in this field and provide a window for newer research avenues in this highly important yet ignored health segment.

The effects of phytosterol and phytostanol supplementation on the lipid profile in postmenopausal women: A systematic review and meta-analysis of randomized controlled trials. Phytother Res 2022; 36:4398-4408. [PMID: 36180973 DOI: 10.1002/ptr.7646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 08/20/2022] [Accepted: 09/18/2022] [Indexed: 02/01/2023]
Abstract
Various studies have proven that phytosterols and phytostanols (PS) are lipid-lowering agents. These compounds play a role in regulating high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), and triglyceride (TG) metabolism. Although various drugs are available and are currently used to treat dyslipidemia, the management of lipid abnormalities during the postmenopausal period remains a challenge. Thus, scientists are trying to develop new strategies to reduce serum lipids concentrations using natural products. However, the impact of PS administration on serum lipids in postmenopausal women remains unclear. Hence, the purpose of this study was to assess the effect of PS supplementation on the lipid profile in postmenopausal women based on a systematic review of the literature and a meta-analysis of randomized controlled trials. PubMed/Medline, Scopus, Embase, and Web of Science were searched to identify suitable papers published until January 18, 2022. We combined the effect sizes with the DerSimonian and Laird method using a random effects model. PS supplementation resulted in a significant decrease in TC (weighted mean difference [WMD]: -16.73 mg/dl) and LDL-C (WMD: -10.06 mg/dl) levels. No effect of PS supplementation on TG (WMD: -1.14 mg/dl) or HDL-C (WMD: -0.29 mg/dl) concentrations was detected. In the stratified analysis, there was a notable reduction in TC and LDL-C levels when the PS dose was ≥2 g/day (TC: -22.22 mg/dl and LDL-C: -10.14 mg/dl) and when PS were administered to participants with a body mass index ≥25 kg/m2 (TC: -20.22 mg/dl and LDL-C: -14.85 mg/dl). PS administration can decrease TC and LDL-C, particularly if the dose of administration is ≥2 g/day and if the participants are overweight or obese. Further high-quality studies are needed to firmly establish the clinical efficacy of PS usage in postmenopausal females.

Abstract
The quest for a food secure and safe world has led to continuous effort toward improvements of global food and health systems. While the developed countries seem to have these systems stabilized, some parts of the world still face enormous challenges. Yam (Dioscorea species) is an orphan crop, widely distributed globally; and has contributed enormously to food security especially in sub-Saharan Africa because of its role in providing nutritional benefits and income. Additionally, yam has non-nutritional components called bioactive compounds, which offer numerous health benefits ranging from prevention to treatment of degenerative diseases. Pharmaceutical application of diosgenin and dioscorin, among other compounds isolated from yam, has shown more prospects recently. Despite the benefits embedded in yam, reports on the nutritional and therapeutic potentials of yam have been fragmented and the diversity within the genus has led to much confusion. An overview of the nutritional and health importance of yam will harness the crop to meet its potential towards combating hunger and malnutrition, while improving global health. This review makes a conscious attempt to provide an overview regarding the nutritional, bioactive compositions and therapeutic potentials of yam diversity. Insights on how to increase its utilization for a greater impact are elucidated.

Abstract
Background Menopause is an important physiological phenomenon in women's lives. Women's concern about taking the hormone treatment to ease menopausal symptoms is increasing. Over the past decade, the use of complementary and alternative medicine for the treatment of menopausal problems instead of hormone therapy has increased. Objective This study aimed to investigate the role of herbal medicine, acupressure, and acupuncture in the menopausal symptoms. Methods Data source: related articles were searched from internal scientific databases and external databases of "Web of Scopus, Cochrane, PubMed, Science Direct, Ovid, and Google scholar." Study Eligibility Criteria The keywords such as menopause, menopausal symptoms, complementary menopausal medicine, acupuncture in menopause, herbal medicine in menopause, and acupuncture in menopause were searched in the studies from 1987 to 2019. Exclusion criteria were inadequate information in the study, lack of access to full-text articles, animal studies, and reports. At the end of the search, 145 articles out of a total of 400 articles were reviewed. Results In various studies, different herbs such as licorice, valerian, soy, sage, ginseng, etc., were used to improve menopausal symptoms. In addition, acupuncture and acupressure were used to reduce menopausal symptoms. Conclusion The efficacy and use of complementary and alternative medicine, along with other classical medicine care, can be a new model for improving menopausal symptoms in women. It is recommended that further clinical and review studies be conducted to develop complementary and alternative medicine.

Abstract
This review attempts to collate existing data and provide the perspectives for future studies on the effects of plants on the male gonads. For many of these medicinal plants such as Lepidium meyenii, Rupus coreanus, Tribulus terrestres, Panax ginseng, Petasites japonicas, Apium graveolens, Eurycoma longifólia, Pedalium murex, Corchorus depressus, Mucuna pruriens, Astragalus membranaceus, Nigella sativa, Crataegus monogyna, Fagara tessmannii, Phaleria macrocarpa, Anacyclus pyrethrum, Cynomorium songaricum and Morinda officinalis, the mechanism of actions of their active principles and crude extracts has been shown in both laboratory animals, in vitro, and human studies, and includes their antioxidant, anti-inflammatory, spermatogenesis-inducing, aphrodisiac, smooth muscle relaxing and androgenic properties. Several active chemical leads including glucosinolates, anthocyanins, protodioscin, ginsenosides, sesquiterpenes, phyto-oestrogens, quassinoids, diosgenin, thymoquinone, proanthocyanidins and bajijiasu isolated from these plants are known to have target effects on the testis, but efforts have been limited in their application at the clinical level. There still appear to be many more extracts of medicinal plants that have not been characterised to determine the phytochemicals unique to them that have target effects on the gonads. Further, collaborative efforts at isolating pro-drug candidates from medicinal plants for studies at the molecular, cellular and clinical level towards elucidating their mechanisms of action on the testes are therefore warranted in the light of the current male fertility crisis.

Abstract
OBJECTIVES To systematically review Clinical Practice Guidelines (CPGs) for the management of menopause-related vasomotor symptoms (VMS) to 1) identify those that include Natural Health Products (NHPs); 2) identify which NHPs were included and the evidence supporting the recommendation for the place in therapy; and 3) compare methodological quality of the CPGs. METHODS PubMed, EMBASE, Web of Science, BMJ Best Practice, DynaMed Plus and websites of gynecological and menopausal societies were searched (Jan 2000-Nov 2018). Records were screened to identify CPGs that were published in English, since 2000 and were for use in North America. CPGs were reviewed for inclusion of NHPs. Data regarding NHPs (evidence, recommendation) were extracted and analyzed. CPGs were critically appraised using the AGREE II tool. RESULTS Five of six CPGs that met general inclusion criteria included NHPs. Black cohosh, isoflavones, soy food/extracts and phytoestrogens were included in all five CPGs. Comparative analysis of recommendations and level of supporting evidence revealed differences. All CPGs included recommendations regarding the use of NHPs in general, although recommendations differed. Four of five CPGs made recommendations for unique NHPs, however, recommendations differed. Using the AGREE II tool, CPGs scored well on domains for purpose and clarity. Lack of detailed description of methodology and author expertise affected scores in other domains. CONCLUSION Five CPGs included general recommendations for the role of NHPs in treating VMS, with recommendations ranging from use with caution to not recommended. There were inconsistencies among CPGs regarding NHPs included and what evidence was used in making recommendations.

Abstract
OBJECTIVE Aging and menopausal changes contribute to increased cardiovascular risks in postmenopausal women. This study examined the associations of total and specific fruit and vegetable consumption with low-density lipoprotein cholesterol (LDL-C) status, a critical cardiovascular risk factor, in early postmenopausal Chinese women. METHODS A total of 508 postmenopausal Hong Kong Chinese women aged 50 to 64 years were recruited into a cohort study on cardiovascular risks. Sociodemographic characteristics, medical conditions, use of medications, and lifestyle factors were obtained via structured interviews. Dietary intake was assessed using a validated food frequency questionnaire. LDL-C and total cholesterol concentrations were determined using biochemical enzymatic techniques and categorized according to the Adult Treatment Panel III classification. RESULTS Ordinal logistic regression analysis showed that women with total fruit and vegetable intake in the highest quartile were 33% less likely (odds ratio [OR] = 0.67; 95% CI, 0.44-1.03) to have a worse LDL-C status than those with lower intake after adjustments. The intakes of total vegetables (OR = 0.63; 95% CI, 0.41-0.96) and vegetable subgroups in the highest quartiles, including darkgreen leafy vegetables (OR = 0.60; 95% CI, 0.41-0.89) and corn and tubers (OR = 0.62; 95% CI, 0.40-0.96), were significantly inversely associated with LDL-C status. Further adjustment for total cholesterol did not attenuate the associations. CONCLUSIONS A daily consumption of vegetables equivalent to about four servings or more might be beneficial for LDL-C control in early Chinese postmenopausal women. In particular, darkgreen leafy vegetables, as well as corn and tubers, deserve greater advocacy for their ability to improve lipid profiles and hence cardiovascular health.

Abstract
Over the past decades, thousands of published studies have amassed supporting recommendations to consume fruits and vegetables for physiological and psychological health. Newer research has emerged to suggest that these plant-based foods contain a plethora of not only vitamins and minerals, but perhaps, most importantly, phytonutrients. These phytonutrients have known pleiotropic effects on cellular structure and function, ultimately resulting in the modulation of protein kinases and subsequent epigenetic modification in a manner that leads to improved outcomes. Even though eating fruits and vegetables is a well-known feature of a healthy dietary pattern, population intakes continue to be below federal recommendations. To encourage consumers to include fruits and vegetables into their diet, an “eat by color” approach is proposed in this review. Although each individual food may have numerous effects based on its constituents, the goal of this simplified approach was to identify general patterns of benefits based on the preponderance of scientific data and known mechanisms of food-based constituents. It is suggested that such a consumer-oriented categorization of these plant-based foods may lead to greater recognition of their importance in the daily diet throughout the lifespan. Other adjunctive strategies to heighten awareness of fruits and vegetables are discussed.

Abstract
Benign Prostate Hyperplasia (BPH) has been associated with prostate cancer prevalent among men after 50 years of age, however, it is unclear whether the antidiabetic drug, metformin, can reduce prostate cancer for men with BPH. The insurance claims data of men aged 50 years or older, with both type 2 diabetes mellitus (T2DM) and BPH diagnosed from 1997 to 2007 were analyzed. Individuals were followed up for at least 5 years. We identified 2906 and 2906 patients as the metformin cohort and nonmetformin cohort, respectively. The Cox method analysis showed that the metformin cohort had an adjusted hazard ratio (aHR) of 0.69 (95% confidence interval [CI] = 0.49‐0.96, P = 0.0298) for prostate cancer, compared to the nonmetformin cohort after controlling for age, traditional Chinese medicine (TCM) use, prostate specific antigen, and Charlson comorbidity index. Patients using TCM for BPH (per 6 months) also had an aHR of 0.41 (95% CI = 0.24‐0.69; P = 0.0009). In conclusion, both metformin medication and TCM use could be associated with reduced risk of prostate cancer for men with BPH and diabetes.

Abstract
Diet and nutrition are important factors in the promotion and maintenance of good health throughout the entire life course. A plant-based diet may be able to prevent and treat chronic diseases such as diabetes, heart disease and hypertension, obesity, chronic inflammation and cancer. Phytonutrient rich foods are found in traditional African diet which is mostly vegetarian, and most of these food plants are often used for medicinal purposes. This review focuses on a peculiar plant Moringa oleifera, called the “Miracle Tree”, considered to be one of nature’s healthiest and most nutritious foods. Countless studies describe the benefits of Moringa leaves, pods, seeds and flowers. Its well-documented role in prevention and treatment of chronic diseases is hypothesized here as a result of possible of cross-kingdom regulation by exogenous vegetal microRNAs and synergistic action of plant bioactive components on endogenous human microRNA regulation. The potential health impact of phytocomplexes from African dietary plants within the context of cross-kingdom and endogenous microRNA regulation on health improvement and the overall economic well-being of the continent is estimated to be enormous.

Abstract
AbstractThis study evaluated the effects of diet containing taro flour on hormone levels and the seminiferous tubules morphology of rats. After weaning, the male rats were divided into two groups (n=12 each): control group (CG) treated with control diet and taro group (TG), fed with 25% taro flour for 90 days. Food, caloric intake, mass and body length were evaluated at experiment end. Testis followed the standard histological processing. Immunostaining was performed using an anti-vimentin antibody to identify Sertoli cells. In histomorphometry, total diameter, total area, epithelial height, luminal height and luminal area were analyzed. The testosterone levels were performed using the radioimmunoassay method. Group TG presented (P<0.05): increase in mass, body length, testicular weight, histomorphometric parameters and hormonal levels. Food intake, calorie and Sertoli cells not presented statistical differences. The taro promoted increase in the testicles parameters and hormones.

Nutrients 2017; 9:nu9121320. [PMID: 29206136 PMCID: PMC5748770 DOI: 10.3390/nu9121320] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2017] [Revised: 11/29/2017] [Accepted: 11/29/2017] [Indexed: 11/16/2022] Open
Abstract
The efficacy of phytosterols extracted from Diascorea alata on antioxidant activities, plasma lipids and hematological profiles was assessed in postmenopausal women. Gas chromatography and mass spectrophotometry was employed to determine the steroid content of Taiwanese yam (Diascorea alata cv. Tainung No. 2). A two-center, randomized, double-blind, placebo-controlled clinical investigation on 50 postmenopausal women randomly assigned to two groups treated for 12 months with placebo or two sachets daily of Diascorea extracts containing 12 mg/dose was carried out. The main outcome measures were the plasma antioxidant activities, hematological profiles, and the concentrations of plasma lipids, including cholesterol, triglyceride, low density lipoprotein, high density lipoprotein, very low density lipoprotein,, and apolipoprotein A1 and B. A one-way analysis of covariance (ANCOVA) test was performed to investigate the significance. Beta-sitosterol, stigmasterol, 22-23-dihydro-, and γ-sitosterol were major phytosterols determined from Diascorea extracts. At six months in those receiving Diascorea, there were significantly decreased leukocyte counts (p < 0.01) and improvement on antioxidant activity of malondialdehyde (p < 0.001). After 12 months’ treatment, elevations of hematocrit and mean corpuscular volume (p < 0.01) were noted in those receiving Diascorea. Moreover, the low dose Diascorea consumption in menopausal women for one year generally did not present positive effects on lipid profiles.

Abstract
The present study was designed to explore whether yam could protect the heart from doxorubicin (DOX)-induced oxidative stress leading to cardiotoxicity in vivo. In this study, the protective effects of water and ethanol extracts of three varieties of yam, including water extracts of Dioscorea japonica Thunb., ethanol extracts of D. japonica Thunb., water extracts of Dioscorea alata, ethanol extracts of D. alata, water extracts of Dioscorea purpurea, and ethanol extracts of D. purpurea, against DOX-induced cardiotoxicity in experimental mice were evaluated. DOX treatment led to significant decreases in the ratio of heart weight to body weight and heart rate, and increases in blood pressure and the serum level of lactate dehydrogenase, a marker of cardiotoxicity, were recovered by yam extracts, especially in water extracts of D. alata. Yam extracts also decreased the cardiac levels of thiobarbituric acid relative substances, reactive oxygen species, and inflammatory factors, as well as the expression of nuclear factor kappa B, while ethanol extracts of D. japonica Thunb. and D. purpurea were shown to be more potent. Moreover, yam extracts had a role in increasing the activities of glutathione peroxidase and superoxide dismutase, thus improving the DOX-induced alterations in oxidative status in the heart tissue of DOX-treated mice. All ethanol extracts of yam exhibited their antiapoptotic abilities on caspase-3 activation and mitochondrial dysfunction, and ethanol extracts of D. alata still exerted a superior effect. Based on these findings, it can be concluded that yam has significant cardioprotective properties against DOX-induced damage via its multiple effects on antioxidant, anti-inflammatory, or antiapoptotic activities.

Nonhormonal management of menopause-associated vasomotor symptoms: 2015 position statement of The North American Menopause Society. Menopause 2016; 22:1155-72; quiz 1173-4. [PMID: 26382310 DOI: 10.1097/gme.0000000000000546] [Citation(s) in RCA: 202] [Impact Index Per Article: 25.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/12/2022]
Abstract
OBJECTIVE To update and expand The North American Menopause Society's evidence-based position on nonhormonal management of menopause-associated vasomotor symptoms (VMS), previously a portion of the position statement on the management of VMS. METHODS NAMS enlisted clinical and research experts in the field and a reference librarian to identify and review available evidence. Five different electronic search engines were used to cull relevant literature. Using the literature, experts created a document for final approval by the NAMS Board of Trustees. RESULTS Nonhormonal management of VMS is an important consideration when hormone therapy is not an option, either because of medical contraindications or a woman's personal choice. Nonhormonal therapies include lifestyle changes, mind-body techniques, dietary management and supplements, prescription therapies, and others. The costs, time, and effort involved as well as adverse effects, lack of long-term studies, and potential interactions with medications all need to be carefully weighed against potential effectiveness during decision making. CONCLUSIONS Clinicians need to be well informed about the level of evidence available for the wide array of nonhormonal management options currently available to midlife women to help prevent underuse of effective therapies or use of inappropriate or ineffective therapies. Recommended: Cognitive-behavioral therapy and, to a lesser extent, clinical hypnosis have been shown to be effective in reducing VMS. Paroxetine salt is the only nonhormonal medication approved by the US Food and Drug Administration for the management of VMS, although other selective serotonin reuptake/norepinephrine reuptake inhibitors, gabapentinoids, and clonidine show evidence of efficacy. Recommend with caution: Some therapies that may be beneficial for alleviating VMS are weight loss, mindfulness-based stress reduction, the S-equol derivatives of soy isoflavones, and stellate ganglion block, but additional studies of these therapies are warranted. Do not recommend at this time: There are negative, insufficient, or inconclusive data suggesting the following should not be recommended as proven therapies for managing VMS: cooling techniques, avoidance of triggers, exercise, yoga, paced respiration, relaxation, over-the-counter supplements and herbal therapies, acupuncture, calibration of neural oscillations, and chiropractic interventions. Incorporating the available evidence into clinical practice will help ensure that women receive evidence-based recommendations along with appropriate cautions for appropriate and timely management of VMS.

Abstract
OBJECTIVE To evaluate the effects of Dioscorea on bilateral ovariectomies-induced cardiac Fasdependent and mitochondria-dependent apoptotic pathways. METHODS Forty-eight female Wistar rats at 6-7 months of age were equally divided into a sham-operated group, and a bilateral ovariectomized (OVX) group for 2 months, and the rats in the OVX group were further fed with 0, 250 or 750 mL/kg Dioscorea spp. daily in the 2nd month. The excised hearts were measured by positive terminal deoxynucleotidyltransferase UTP nick end labeling (TUNEL) assays, western blotting and reverse transcription-polymerase chain reaction. RESULTS Dioscorea spp. decreased OVX-induced cardiac TUNEL-positive apoptotic cells; decreased OVX-induced TNF-alpha, Fas ligand, Fas death receptors, Fas-associated death domain, activated caspase-8, and -3 (Fas pathways); decreased OVX-induced Bad, Bax, Bax-to-Bcl2 ratio, activated caspase-9, and -3 (mitochondria pathway). CONCLUSIONS Dioscorea spp. prevented ovariectomy-induced cardiac Fas-dependent and mitochondriadependent apoptotic pathways in rat models. The fifi ndings may provide possible therapeutic effects of dioscorea for potentially preventing cardiac apoptosis after ovariectomy or post-menopause.

Abstract
Medicinal Plants Used for Treating Reproductive Health Care Problems in Cameroon, Central Africa. Approximately 80% of the African population uses traditional plants to deal with health problems, basically because of their easy accessibility and affordability. This study was carried out to document indigenous knowledge of medicinal plants used by traditional healers and elders in the treatment of reproductive health care in the Bamboutos Division of the West Region in Cameroon, Central Africa. The research methods used included semi-structured interviews and participative field observations. For the interviews, 70 knowledgeable respondents (40 traditional healers and 30 elders) were selected via purposive sampling. Voucher specimens were collected with the help of respondents, processed into the Cameroon National Herbarium in Yaoundé following standard methods, identified with the help of pertinent floras and taxonomic experts, and submitted to Department of Botany at the University of Dschang. Descriptive statistics were used to analyze and summarize ethnobotanical information obtained. Informant consensus factors (ICF) were used to elucidate the agreement among informants on the species to be used in the treatment within a category of illness. The results showed that a total of 70 plant species from 37 families (mostly of the Asteraceae [8 species], Euphorbiaceae [7], and Acanthaceae and Bignoniaceae [4 each]) are used in the treatment of 27 reproductive ailments, with the highest number of species (37) being used against venereal diseases, followed by female (29) and male infertility (21), respectively. Leaves (47.3%) were the most commonly harvested plant parts and the most common growth forms harvested were the herbs (45.7%), followed by shrubs (30%). Sixty percent of plant material was obtained from the wild ecosystems. Herbal remedies were mostly prepared in the form of decoction (66.2%) and were taken mainly orally. Informant consensus about usages of medicinal plants ranged from 0.5 to 1.0 with an average value of 0.91. It can be concluded that medicinal plants have played and will continue to play major roles in the management of reproductive healthcare in the study area.

Abstract
Rhizomes of Dioscorea species are traditionally used for relieving menopausal syndromes in Chinese medicine. The estrogen-stimulating bioactive principles have been demonstrated in our previous study. In this study, the estrogen-stimulating effects of proteins isolated from four Dioscorea species [D. alata L. (DA), D. zingiberensis C.H. Wright (DH), D. collettii var. hypoglauca (Palib.) S.J. Pei & C.T. Ting (DH), and D. oppositifolia L. (DO)] have been investigated and compared. Microscopic authentication of four Dioscorea species was performed by using paraffin and powder sections of the rhizomes. The potential bioactive proteins of four Dioscorea species have been rapidly isolated by using a DOI-antibody affinity column chromatography on immobilized antibodies against on estradiol-stimulating protein from DO (DOI), and their bioactivity has been rapidly confirmed and compared by phenotypic (i.e., estradiol-stimulating effect) and target-based (i.e., STAR, aromatase, estrogen receptors) screening approaches. The estrogen-stimulating activity of bioactive proteins from DO is the highest. In addition, bioactive proteins from DO upregulated the estradiol-metabolizing enzymes (aromatase and steroidogenic acute regulatory protein). Meanwhile, bioactive proteins from DA, DH and DO upregulated estrogen receptor β (ERβ). All bioactive proteins did not change the expression of estrogen receptor β (ERα). The estrogen-stimulating bioactive proteins isolated from DO increased biosynthesis of estradiol and upregulated the protein expression of aromatase, steroidogenic acute regulatory protein, and ERβ. The results scientifically support the traditional use of DO in Chinese medicine for relieving menopausal syndrome. Besides, proteins from DA and DZ could also upregulate the translational levels of ERβ, and potentially reducing the risk of ovarian cancer, which also support the clinical use of them for treating female aging disorder.

Abstract
Starchy roots and tuber crops play a pivotal role in the human diet. There are number of roots and tubers which make an extensive biodiversity even within the same geographical location. Thus, they add variety to the diet in addition to offering numerous desirable nutritional and health benefits such as antioxidative, hypoglycemic, hypocholesterolemic, antimicrobial, and immunomodulatory activities. A number of bioactive constituents such as phenolic compounds, saponins, bioactive proteins, glycoalkaloids, and phytic acids are responsible for the observed effects. Many starchy tuber crops, except the common potatoes, sweet potatoes, and cassava, are not yet fully explored for their nutritional and health benefits. In Asian countries, some edible tubers are also used as traditional medicinal. A variety of foods can be prepared using tubers and they may also be used in industrial applications. Processing may affect the bioactivities of constituent compounds. Tubers have an immense potential as functional foods and nutraceutical ingredients to be explored in disease risk reduction and wellness.

Abstract
INTRODUCTION Studies show that patients with cancer who use complementary and alternative medicine (CAM) have a poorer survival prognosis than those who do not. It remains unclear whether this is due to a priori poorer prognosis that makes patients turn to CAM, or whether there is a factor associated with CAM use itself that influences the prognosis negatively. Healthcare providers should assist patients in safeguarding their treatment decision. However, the current non-communication between CAM and conventional providers leaves it up to the patients themselves to choose how to best integrate the two worlds of therapy. In this study, an interactive shared decision-making (SDM) tool will be developed to enable patients and health professionals to make safe health choices. METHODS AND ANALYSIS We will delineate, compare and evaluate perception and clinical experience of communication of risk situations among oncology experts, general practitioners and CAM practitioners. To accomplish this, we will develop a pilot and implement a large-scale survey among the aforementioned health professionals in Norway. Guided by the survey results, we will develop a β-version of a shared decision-making tool for healthcare providers to use in guiding patients to make safe CAM decisions. ETHICS AND DISSEMINATION Participants must give their informed and written consent before inclusion. They will be informed about the opportunity to drop out from the study followed by deletion of all data registered. The study needs no approval from The Regional Committee for Medical and Health Research Ethics because all participants are healthcare professionals. Results from this study will be disseminated in peer-reviewed medical journals.

Abstract
Given the persistent confusion about the risks and benefits of hormone therapy since 2002 and the first publication from the Women's Health Initiative's primary findings, women and health care providers are increasingly motivated to find effective, nonhormonal approaches to treat menopause-related symptoms. Complementary and alternative medicine has grown increasingly popular in the last decade. A wide array of botanic medicines is offered as an alternative approach to hormone therapy for menopause, but data documenting efficacy and safety are limited. None of the available botanicals is as effective as hormone therapy in the management of vasomotor symptoms.

Abstract
A novel protein, designated as DOI, isolated from the Chinese yam (Dioscorea opposita Thunb.) could be the first protein drug for the treatment of menopausal syndrome and an alternative to hormone replacement therapy (HRT), which is known to have undesirable side effects. DOI is an acid- and thermo-stable protein with a distinctive N-terminal sequence Gly-Ile-Gly-Lys-Ile-Thr-Thr-Tyr-Trp-Gly-Gln-Tyr-Ser-Asp-Glu-Pro-Ser-Leu-Thr-Glu. DOI was found to stimulate estradiol biosynthesis in rat ovarian granulosa cells; induce estradiol and progesterone secretion in 16- to 18-month-old female Sprague Dawley rats by upregulating expressions of follicle-stimulating hormone receptor and ovarian aromatase; counteract the progression of osteoporosis and augment bone mineral density; and improve cognitive functioning by upregulating protein expressions of brain-derived neurotrophic factor and TrkB receptors in the prefrontal cortex. Furthermore, DOI did not stimulate the proliferation of breast cancer and ovarian cancer cells, which suggest it could be a more efficacious and safer alternative to HRT.

Abstract
AIMS To determine the effects of herbal therapies on hot flushes and at least one other symptom including, sleep, mood, cognition, and pain that women experience during the menopausal transition and early postmenopause. METHODS An extensive search of PubMed/Medline, CINAHL Plus, PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science, EMBASE, AMED, and Alt-Health Watch for randomized, controlled trials reported in English between January 2004 and July was conducted by an experienced reference librarian. There were 1193 abstracts identified but only 58 trials examined effectiveness of therapies for hot flushes and at least one additional co-occurring symptom. RESULTS Seventeen studies used herbal preparation including seven studies of black cohosh, two studies of black cohosh mixed with other herbals, and eight studies of other herbals. Of these, one study of black cohosh, two studies of black cohosh mixed with other herbals, and four other herbal studies had significant effects on hot flushes and at least one additional co-occurring symptom. The adverse events of herbal therapies were various, ranging from mild to moderate and women were generally tolerant of the preparations. CONCLUSIONS Black cohosh mixed with other herbals, Rheum rhaponticum, and French maritime pine bark had significant effects on hot flushes and at least one other symptom. These herbal therapies may be a promising alternative treatment to hormonal treatment. Future studies should classify women based on their menopausal stages, report each symptom separately, have adequate sample size, focus on multiple co-occurring symptoms, and target symptom management of menopausal symptoms.

Abstract
One of the important factors in aging is oxidative stress and aging-related disturbances are believed be ameliorated by antioxidants. Diosgenin is a bio-active ingredient of dioscorea that is widely used in Chinese medicine, shows anti-oxidant activity and improves some aging-related deficits in senescent and menopausal animals. We compared alterations in behavior, biochemical parameters (plasma levels of the uric acid, creatinine, calcium, phosphate, total cholesterol, low-density lipoprotein cholesterol and triglycerides, and the plasma activity of aminotransferases AST and ALT), and sperm motility in two models of accelerated senescence (d-galactose-induced (150 mg/kg/day, i.p., 57 days) aging in Wistar rats vs. genetically defined in OXYS rats) and examined the protective effects of diosgenin (10 or 50mg/kg/day, p.o., 57 days). Both models had augmented levels of ALT activity indicating hepatopathology. Compared to d-galactose-treated animals, OXYS rats demonstrated profound biochemical alterations (hypocalcemia, hypophosphatemia, and hypocholesterolemia) and behavioral deficits (impaired object recognition, decreased sexual motivation and locomotor activity, retarded learning) that confirmed the difference in the mechanisms of accelerated senescence in these models. We first showed diminished sperm motility in males of both models of accelerated senescence studied. Chronic diosgenin treatment failed to improve biochemical and behavioral disturbances and had some undesirable side effects on body weight and working memory in OXYS rats. However, diosgenin restored moderately decreased sperm motility in d-galactose-treated Wistar males and might be recommended for treatment of mild age-related reproductive dysfunctions.

Abstract
Northern Peru represents the center of the Andean "health axis," with roots going back to traditional practices of Cupisnique culture (1000 BC). For more than a decade of research, semistructured interviews were conducted with healers, collectors, and sellers of medicinal plants. In addition, bioassays were carried out to evaluate the efficacy and toxicity of plants found. Most of the 510 species encountered were native to Peru (83%). Fifty percent of the plants used in colonial times have disappeared from the pharmacopoeia. Market vendors specialized either on common and exotic plants, plants for common ailments, and plants only used by healers or on plants with magical purposes. Over 974 preparations with up to 29 different ingredients were used to treat 164 health conditions. Almost 65% of the medicinal plants were applied in these mixtures. Antibacterial activity was confirmed in most plants used for infections. Twenty-four percent of the aqueous extracts and 76% of the ethanolic extracts showed toxicity. Traditional preparation methods take this into account when choosing the appropriate solvent for the preparation of a remedy. The increasing demand for medicinal species did not increase the cultivation of medicinal plants. Most species are wild collected, causing doubts about the sustainability of trade.

Abstract
Dioscorea species is a very important food and drug plant. The tubers of the plant are extensively used in food and drug purposes owing to the presence of steroidal constituent's diosgenin in the tubers. In the present study, we report for the first time that the leaves of Dioscorea composita and Dioscorea floribunda grown under the field conditions exhibited the presence of multicellular oil glands on the epidermal layers of the plants using stereomicroscopy (SM) and scanning electron microscopy (SEM). Essential oil was also isolated from the otherwise not useful herbage of the plant, and gas chromatographic-mass spectroscopy analysis revealed confirmation of the essential oil constituents. Out of the 76 compounds detected in D. floribunda and 37 from D. composita essential oil, major terpenoids which are detected and reported for Dioscorea leaf essential oil are α-terpinene, nerolidol, citronellyl acetate, farnesol, elemol, α-farnesene, valerenyl acetate, and so forth. Elemol was detected as the major constituent of both the Dioscorea species occupying 41% and 22% of D. Floribunda and D. composita essential oils, respectively. In this paper, we report for the first time Dioscorea as a possible novel bioresource for the essential oil besides its well-known importance for yielding diosgenin.

Abstract
Complementary and alternative medicines (CAM) such as isoflavones and black cohosh are commonly used to deal with menopausal symptoms, but benefit a limited proportion of women. The aim of this minireview is to summarize the evidence of the efficacy and safety of other herbal preparations. Randomized controlled trials (RCTs) find that the extracts of Mediterranean pine bark (Pycnogenol(®)), linseed, and Lepididium meyenii (Maca) reduce vasomotor symptoms. The results of RCTs of the hop flavonoid 8-prenylnaringenin are conflicting. Animal and human studies suggest that Dioscorea villosa (Wild yam),and Broccoli may protect against osteoporosis and breast and gynecological cancers but further evidence is required. Linseed may protect against breast cancer but the results are conflicting.

Abstract
We studied the estrogenic activity and cellular effect of wild yam extract in MCF-7 human breast cancer cells. The extract increased the activity of the progesterone receptor and pS2 genes at the mRNA levels in human breast cancer MCF-7 cells, although the effects were not as prominent as those of 17β-estradiol (E2). Western blot analysis showed that the level of estrogen receptor α protein was down-regulated after treatment with E2 or wild yam extract. Wild yam extract also inhibited proliferation of MCF-7 cells. These data indicate that wild yam extract acts as a weak phytoestrogen and protects against proliferation in human breast carcinoma MCF-7 cells.

Abstract
A large number of women will pass through menopause each year. Women in menopausal transition experience a variety of menopausal symptoms. Although hormonal therapy remains the most effective treatment, side effects have been reported by several large studies. An increased number of women seek the use of complementary and alternative medicine (CAM) for treating menopausal symptoms. This review analyzes the evidence from systematic reviews, randomized controlled trials and epidemiological studies of using herbal medicine (Black cohosh, Dong quai, St John's wart, Hops, Wild yam, Ginseng, and evening primrose oil) and acupuncture for the treatment of menopausal symptoms. Evidence supporting the efficacy and safety of most CAM for relief of menopausal symptoms are limited. Future larger and better controlled studies testing the effectiveness of these treatments are needed.

Abstract
BACKGROUND It remains unclear whether estrogenic botanical supplement (EBS) use influences breast cancer survivors' health-related outcomes. METHODS We examined the associations of EBS use with health-related quality of life (HRQOL), with fatigue, and with 15 hormone-related symptoms such as hot flashes and night sweats among 767 breast cancer survivors participating in the Health, Eating, Activity, and Lifestyle (HEAL) Study. HRQOL was measured by the Medical Outcomes Study short form-36 physical and mental component scale summary score. Fatigue was measured by the Revised-Piper Fatigue Scale score. RESULTS Neither overall EBS use nor the number of EBS types used was associated with HRQOL, fatigue, or hormone-related symptoms. However, comparisons of those using each specific type of EBS with non-EBS users revealed the following associations. Soy supplements users were more likely to have a better physical health summary score (odds ratio [OR] = 1.66, 95% confidence interval [CI] = 1.02-2.70). Flaxseed oil users were more likely to have a better mental health summary score (OR = 1.76, 95% CI = 1.05-2.94). Ginseng users were more likely to report severe fatigue and several hormone-related symptoms (all ORs ≥ 1.7 and all 95% CIs exclude 1). Red clover users were less likely to report weight gain, night sweats, and difficulty concentrating (all OR approximately 0.4 and all 95% CIs exclude 1). Alfalfa users were less likely to experience sleep interruption (OR = 0.28, 95% CI = 0.12-0.68). Dehydroepiandrosterone users were less likely to have hot flashes (OR = 0.33, 95% CI = 0.14-0.82). CONCLUSIONS Our findings indicate that several specific types of EBS might have important influences on a woman's various aspects of quality of life, but further verification is necessary.

Abstract
Diosgenin, a traditional Yam extraction, has been used in hormone replacement for menopausal women. We aimed to investigate the influences of diosgenin administration upon the MMP-2 and -9 activity and expression and reproductive hormones of ovariectomized (OVX) rats, a model of menopausal status. Seven-week old female Wistar rats with bilateral OVX or sham operation (controls) were divided and administered different dosages of diosgenin (0, 10, 50, or 100 mg/kg/day) for 8 weeks. Serum was then sampled for progesterone (P4) and estradiol (E2) assay and uterine horns harvested. Myometrial MMP-2 and -9 activity and expression were surveyed and myometrial collagen expression was also assayed. The results show higher body weight in OVX rats across the 8 weeks post surgery and no significant differences were noted among OVX or Sham rats with diosgenin supplements. There were lower P4 and E2 concentrations in OVX rats compared to Sham rats, and higher P4 concentration of Sham rats post diosgenin supplement. MMP-2 and -9 mRNA expression and activity was lower in OVX rats, although higher MMP-2 and lower MMP-9 activity/mRNA expression was observed in OVX rats post diosgenin supplementation. Collagen mRNA expression was higher in OVX rats compared to Sham controls, and diosgenin administration decreased collagen mRNA expression in OVX rats. In conclusion, diosgenin is associated with gelatinase expression and collagen metabolism in OVX rats. Diosgenin administration can partially reverse the effects of OVX upon MMP functions and hormone status. Adequate diosgenin supplement might modulate myometrial gelatinase expression and collagen metabolism in menopausal subjects.

Abstract
Background Proprotein convertase subtilisin-like kexin type 9 (PCSK9) plays a key role in regulating plasma low-density lipoprotein cholesterol (LDL-C) levels. However, the association of E670G (rs505151) polymorphism in the PCSK9 gene and serum lipid levels is inconsistent in several previous studies. The present study was undertaken to detect the association of PCSK9 E670G polymorphism and several environmental factors with serum lipid levels in the Guangxi Bai Ku Yao and Han populations. Methods A total of 649 subjects of Bai Ku Yao and 646 participants of Han were randomly selected from our previous samples. Genotypes of the PCSK9 E670G polymorphism were determined via polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis, and then confirmed by direct sequencing. Results Serum levels of total cholesterol, high-density lipoprotein cholesterol (HDL-C), LDL-C, and apolipoprotein (Apo) AI were lower in Bai Ku Yao than in Han (P < 0.01 for all). The frequency of G allele was 2.00% in Bai Ku Yao and 4.80% in Han (P < 0.01). There was significant difference in the genotypic and allelic frequencies between Bai Ku Yao and Han (P < 0.01); between normal LDL-C (≤ 3.20 mmol/L) and high LDL-C subgroups (> 3.20 mmol/L, P < 0.01) in Bai Ku Yao; and between normal HDL-C (≥ 0.91 mmol/L) and low HDL-C (< 0.91 mmol/L, P < 0.05), between normal ApoAI (≥ 1.00 g/L) and low ApoAI (< 1.00 g/L, P < 0.05), or between normal ApoAI/ApoB ratio (≥ 1.00) and low ApoAI/ApoB ratio (< 1.00, P < 0.01) subgroups in Han. The G allele carriers in Han had higher serum HDL-C levels and the ratio of ApoAI to ApoB than the G allele noncarriers. The G allele carriers in Han had higher serum HDL-C and ApoAI levels than the G allele noncarriers in males (P < 0.05 for each), whereas the G allele carriers had lower serum ApoB levels and higher the ratio of ApoAI to ApoB than the G allele noncarriers in females (P < 0.05 for all). Serum HDL-C and ApoAI levels in Han were correlated with genotypes (P < 0.05) in males, and serum ApoB levels and the ratio of ApoAI to ApoB were associated with genotypes (P < 0.05) in females. Conclusions The PCSK9 E670G polymorphism is mainly associated with some serum lipid parameters in the Han population. The G allele carriers had higher serum HDL-C and ApoAI levels in males, and lower serum ApoB levels and higher the ApoAI/ApoB ratio in females than the G allele noncarriers.

Abstract
Infections of the reproductive tract, complications after childbirth, and reproductive problems continue to be a major health challenge worldwide. An impressive number of plant species is traditionally used to remedy such afflictions, and some have been investigated for their efficacy with positive results. A total of 105 plant species belonging to 91 genera and 62 families were documented and identified as herbal remedies for reproductive problems in Northern Peru. Most species used were Asteraceae (9.52%), followed by Lamiaceae and Fabaceae (8.57% and 6.67%). The most important families are clearly represented very similarly to their overall importance in the local pharmacopoeia. The majority of herbal preparations for reproductive afflictions were prepared from the leaves of plants (22.72%), the whole plant (21.97%), and stems (21.21%), while other plant parts were used less frequently. More than 60% of the cases fresh plant material was used to prepare remedies. Over 70% of the remedies were applied orally, while the remaining ones were applied topically. Many remedies were prepared as mixtures of multiple ingredients. Little scientific evidence exists to prove the efficacy of the species employed as reproductive disorder remedies in Northern Peru. Only 34% of the plants found or their congeners have been studied at all for their medicinal properties. The information gained on frequently used traditional remedies might give some leads for future targets for further analysis in order to develop new drugs.

OBJECTIVE The aim of this study was to assess the efficacy and safety of Diascorea alata for treatment of menopausal symptoms. MATERIALS AND METHODS Two-center, randomized, double-blind, placebo-controlled clinical investigation on 50 menopausal women randomly assigned to two groups, treated for 12 months with either placebo or two sachets daily of Diascorea extracts containing 12 mg/sachet. Primary outcome measures were changes in the Greene Climacteric Scale caused by Diascorea compared with placebo; secondary outcomes were changes in plasma hormone profiles. One-way ANCOVA test was performed to investigate the significance. RESULTS At 6 months and at the end of treatment, those women who received Diascorea showed general improvement in almost all the clinical symptoms investigated. A significant reduction was noted in the total Greene scores in the Diascorea group assessed at the end of 12 months' treatment (p < 0.01). This phenomenon was more significant for the psychological parameters of anxiety than for other parameters. Apparent improvements were noted in the parameters 'feeling tense or nervous' (p = 0.007), 'insomnia' (p = 0.004), 'excitable' (p = 0.047) and 'musculoskeletal pain' (p = 0.019) among those receiving Diascorea. Diascorea consumption also resulted in positive effects on blood hormone profiles. CONCLUSIONS Compared with placebo, Diascorea alata improves symptoms, particularly the psychological parameters in menopausal women. Safety monitoring indicated that standardized extracts of Diascorea alata were safe during daily administration over a period of 12 months.

Breast cancer survivors who use estrogenic botanical supplements have lower serum estrogen levels than non users. Breast Cancer Res Treat 2009; 117:111-9.

Abstract
To measure the association between use of estrogenic botanical supplements and serum sex hormones in postmenopausal breast cancer survivors, a total 502 postmenopausal women were queried 2-3 years after breast cancer diagnosis about their use of botanical supplements, and supplements were categorized according to their estrogenic properties. Concurrently, a fasting blood sample was obtained for assay of estrone, estradiol, free estradiol, testosterone, free testosterone, dehydroepiandrosterone sulfate (DHEAS), and sex hormone-binding globulin. Adjusted means of the serum hormones were calculated by use of estrogenic supplements. Women reporting use of any estrogenic botanical supplement had significantly lower levels of estrone (20.8 vs. 23.6 pg/ml), estradiol (12.8 vs. 14.7 pg/ml), free estradiol (0.29 vs. 0.35 pg/ml), and DHEAS (47.7 vs. 56.2 microg/dl) compared to women reporting no use. Data from this cross-sectional study suggest the use of estrogenic botanical supplements may be associated with sex hormone concentrations in breast cancer survivors. Considering the high use of these supplements among breast cancer patients, further research is needed to clarify the relative estrogenicity/antiestrogenicity of these compounds and their relation with prognosis.

Abstract
Hormone-related supplements (HRS), many of which contain phytoestrogens, are widely used to manage menopausal symptoms, yet their relationship with breast cancer risk has generally not been evaluated. We evaluated whether use of HRS was associated with breast cancer risk, using a population-based case-control study in 3 counties of the Philadelphia metropolitan area consisting of 949 breast cancer cases and 1,524 controls. Use of HRS varied significantly by race, with African American women being more likely than European American women to use any herbal preparation (19.2% vs. 14.7%, p=0.003) as well as specific preparations including black cohosh (5.4% vs. 2.0%, p=0.003), ginseng (12.5% vs. 7.9%, p<0.001) and red clover (4.7% vs. 0.6%, p<0.001). Use of black cohosh had a significant breast cancer protective effect (adjusted odds ratio 0.39, 95% CI: 0.22-0.70). This association was similar among women who reported use of either black cohosh or Remifemin (an herbal preparation derived from black cohosh; adjusted odds ratio 0.47, 95% CI: 0.27-0.82). The literature reports that black cohosh may be effective in treating menopausal symptoms, and has antiestrogenic, antiproliferative and antioxidant properties. Additional confirmatory studies are required to determine whether black cohosh could be used to prevent breast cancer.

Abstract
Sesame ingestion has been shown to improve blood lipids in humans and antioxidative ability in animals. Sesamin, a sesame lignan, was recently reported to be converted by intestinal microflora to enterolactone, a compound with estrogenic activity and also an enterometabolite of flaxseed lignans, which are known to be phytoestrogens. Whether sesame can be a source of phytoestrogens is unknown. This study was designed to investigate the effect of sesame ingestion on blood sex hormones, lipids, tocopherol, and ex vivo LDL oxidation in postmenopausal women. Twenty-six healthy subjects attended, and 24 completed, this randomized, placebo-controlled, crossover study. Half of them consumed 50 g sesame seed powder daily for 5 wk, followed by a 3-wk washout period, then a 5-wk 50-g rice powder placebo period. The other half received the 2 supplements in reverse order. After sesame treatment, plasma total cholesterol (TC), LDL-C, the ratio of LDL-C to HDL-C, thiobarbituric acid reactive substances in oxidized LDL, and serum dehydroepiandrosterone sulfate decreased significantly by 5, 10, 6, 23, and 18%, respectively. The ratio of alpha- and gamma-tocopherol to TC increased significantly by 18 and 73%, respectively. All of these variables differed significantly between the 2 treatments. Serum sex hormone-binding globulin and urinary 2-hydroxyestrone (n = 8) increased significantly by 15 and 72%, respectively, after sesame treatment, and these concentrations tended to differ (P = 0.065 and P = 0.090, respectively) from those after the placebo treatment. These results suggest that sesame ingestion benefits postmenopausal women by improving blood lipids, antioxidant status, and possibly sex hormone status.
