Regarding cancer, scientific evidence suggests that isoflavones could be useful in reducing the risk of suffering some types of cancer, such as breast and endometrial cancer, but further studies are needed to confirm these results. Hosoda K., Furuta T., Yokokawa A., Ishii K. Identification and quantification of daidzein-7-glucuronide-4-sulfate, genistein-7-glucuronide-4-sulfate and genistein-4,7-diglucuronide as major metabolites in human plasma after administration of kinako. Phenolic compounds are secondary metabolites, which are produced by plants as a defense mechanism against infection, water stress, cold stress, ultraviolet radiation and high visible light, among others [1,2]. Yan Z., Zhang X., Li C., Jiao S., Dong W. Association between consumption of soy and risk of cardiovascular disease: A meta-analysis of observational studies. In view of these results, we can conclude that there is scientific evidence that supports the beneficial effect of isoflavones on bone health and thus in the prevention and treatment of osteoporosis in postmenopausal women. Further, Chalvon-Demersay et al. With regard to isoflavone content in foodstuffs, it has been observed that in soybeans, the amount of these phenolic compounds ranges from 1.2 to 4.2 mg per g on dry weight, whereas in red clover, the amount varies between 10 and 25 mg per g on dry weight [15,16]. Grosso et al. Sarri G., Pedder H., Dias S., Guo Y., Lumsden M.A. As it has been stated in the Bioavailability section, microbiota composition in humans makes equol production very variable, which yields high interindividual differences. (2018) revised 13 epidemiologic studies involving 178,947 participants: 7067 cases and 171,880 controls; among them, three were prospective cohort studies, and ten were population-based case-control studies [71]. After the consumption of around 17 mg of isoflavones per day, the median plasma concentrations of genistein, glycitein, daidzein and equol were 245.3 ng/mL, 9.8 ng/mL, 86.8 ng/mL and 12.7 ng/mL, respectively. In fact, the number of isoflavones present was very variable among the different soy food types. Abdi F., Alimoradi Z., Haqi P., Mahdizad F. Effects of phytoestrogens on bone mineral density during the menopause transition: A systematic review of randomized, controlled trials. Zhao T.T., Jin F., Li J.G., Xu Y.Y., Dong H.T., Liu Q., Xing P., Zhu G.L., Xu H., Miao Z.F. At high elevations, acidic fog and clouds might . They performed a separated meta-analysis for each of the interventions, including dietary soy isoflavones (including four studies), supplements and extracts of soy isoflavones (including six studies) and red clover isoflavones (including seven studies). The gravitational attraction between the Earth and the Moon produces two bulges in the ocean on opposite sides of the Earth. Only one study examined the effects of red clover on night sweats, and a significant association was found, which showed a decreased frequency in night sweats. Santo A.S., Santo A.M., Browne R.W., Burton H., Leddy J.J., Horvath S.M., Horvath P.J. 1Nutrition and Obesity Group, Department of Pharmacy and Food Science, University of the Basque Country (UPV/EHU) and Lucio Lascaray Research Institute, 01006 Vitoria, Spain; sue.uhe@zemog.aoias (S.G.-Z. For their meta-analysis, Jiang et al. The association between dietary isoflavones intake and gastric cancer risk: A meta-analysis of epidemiological studies. In the last few decades, scientific evidence has stressed the importance of plants in the prevention and/or supportive treatment of a plethora of diseases, many of them chronic, age-associated disorders. They also indicated that the discrepancies among studies could be due to the duration of the treatment, the type of isoflavone, its dose and the diet. A total of 16 studies were included in their meta-analysis with a range of 24 to 236 subjects. Furthermore, the dose-response analysis revealed an 8% reduction in colorectal neoplasm risk for every 20 mg/day increase in isoflavone intake in Asian populations, and for every 0.1 mg/day increase in Western populations. (2017) conducted a meta-analysis with ten observational studies to assess the association between the isoflavone compounds daidzein, genistein and equol, and breast cancer [61]. Importantly, the soy variety, environmental conditions of the culture and the processing of soybeans notably influence their isoflavone content [18]. Sansai et al. The majority of the studies that used display stimuli, such as photos, 3D images, virtual reality, and videos of natural landscapes, confirmed that viewing natural scenery led to more relaxed body responses than viewing the control. official website and that any information you provide is encrypted (2018), 30 articles were included for analysis; 15 of them were case-control studies, eight cohort studies and seven nested case-control studies [76]. 8600 Rockville Pike In their systematic revision, which included 1307 menopausal (n = 139) and post-menopausal (n = 1268) women, Perna et al. After an extensive bibliographical review, the expert panel concluded that the results of observational studies do not support the hypothesis of an increased risk of breast cancer after isoflavone-rich food supplement intake [93]. PV panels have been linked . Franco et al. Atkinson C., Frankenfeld C.L., Lampe J.W. (2016), nine studies addressed to menopausal women and focused on bone health were analyzed [52]. Global climate change is not a future problem. Lambert M.N.T., Hu L.M., Jeppesen P.B. (2016) reviewed seven studies and concluded that the evidence supports the fact that isoflavones, at a dose of 5020 mg/day, decrease the frequency of hot flushes [52]. Future research in this field should quantify isoflavones as accurately as possible, analyzing larger cohorts and lengthening the follow-up stage. Sfakianos J., Coward L., Kirk M., Barnes S. Intestinal uptake and biliary excretion of the isoflavone genistein in rats. But that doesn't mean that they dig in their heels and argue about it. Kim Y., Je Y. Flavonoid intake and mortality from cardiovascular disease and all causes: A meta-analysis of prospective cohort studies. Modified from Wang et al., 2006 [4]. Effects of isoflavones in menopausal symptoms. Thus, its consumption, according to epidemiological and clinical studies, has been postulated to be related to a decrease in the risk of different diseases. Influence of cellular ERalpha/ERbeta ratio on the ERalpha-agonist induced proliferation of human T47D breast cancer cells. Kov L., Dadkov K., Kaparovsk J., Kaparovsk T. Isoflavones. Moreover, this association was more prominent among postmenopausal women than premenopausal women. The two systematic reviews conclude that isoflavones have an important role in reducing hot flushes [52,53], although some observations need to be pointed out. (2016) published a meta-analysis of 13 case-control and four prospective cohort studies, where the results revealed that soy isoflavone consumption reduced the risk of developing colorectal cancer by 23% [79]. This fact suggests that other components, such as fiber in the soy foods, may account for these negative associations. Study duration ranged from four weeks to two years, with a median of 12 weeks. Metabolites of dietary (soya) isoflavones in human urine. In addition, several studies have observed that the urine excretion of daidzein metabolites is notably higher than that of genistein metabolites [44,45,46]. You J., Sun Y., Bo Y., Zhu Y., Duan D., Cui H., Lu Q. Ingram D., Sanders K., Kolybaba M., Lopez D. Case-control study of phyto-oestrogens and breast cancer. Nevertheless, it is important to consider this metabolite since it is key in the biological activity of isoflavones [13]. Due to the presence of biologically active compounds, walnut was used in the . It has been described that after the oral intake of isoflavones, their peak plasma concentration in humans occurs at around seven hours [33]. Our findings illustrate that foraging rodents, well known to be risk-averse during moonlit nights, are also affected by the presence of an invasive plant. National Library of Medicine Rizzo G., Baroni L. Soy, Soy Foods and Their Role in Vegetarian Diets. In contrast, the effects on bone resorption biomarkers were more favorable in overweight or obese women than in women with a healthy weight. Zhong X.S., Ge J., Chen S.W., Xiong Y.Q., Ma S.J., Chen Q. They observed that it was dose-dependent at low to moderate soybean consumption. Contraction stimulates translocation of glucose transporter GLUT4 in skeletal muscle through a mechanism distinct from that of insulin. However, the authors stated that they could not reach definitive conclusions due to, among other reasons, the lack of inclusion in the review of randomized controlled clinical trials focused on the treatment of osteoporosis in early menopause. (2016) conducted a meta-analysis of 18 studies involving 16,917 colorectal cancer cases in 559,486 participants [78]. With regard to prostate cancer, it has been proposed that it might be affected by isoflavone consumption due to its effect on hormone metabolism. The authors suggested that further studies grouping subjects by isoflavone intake or by the circulating isoflavone levels might enhance this association. Moreover, Rienks et al. Dietary intake of flavonoid subclasses and risk of colorectal cancer: Evidence from population studies. Moreover, sodium-dependent glucose transporter 1 (SGLT1) allows phenolic compound-glycosylates to directly enter into epithelial cells, where they are hydrolyzed by cytosolic glucosidases [30,31]. Rienks et al. The authors reported that neither soy food intake nor circulating isoflavones were associated with a reduced risk of prostate cancer. (2020) revealed that supplementation of soy isoflavones had a positive effect in reducing arterial stiffness, also known as the loss of arterial elasticity [59]. Estradiol, which has proven efficacy on hot flushes, needs 3.09 weeks to achieve half of its peak activity, while isoflavones require 13.4 weeks, suggesting that 12 weeks of treatment is not enough for soy isoflavones to exert a beneficial effect. (2020) carried out a meta-analysis with 15 cohort studies with the aim of exploring the association between isoflavone intake (<62.7 mg/day) and breast cancer mortality and its recurrence [68]. In like manner, a meta-analysis by Simental-Menda et al. (2019) studied whether equol supplementation could benefit equol nonproducer subjects in lowering the incidence and severity of hot flushes [85]. Thus, soybean can be considered as the best food source. Efficacy of phytoestrogens for menopausal symptoms: A meta-analysis and systematic review. Regarding cancer, scientific evidence suggests that isoflavones could be useful in reducing the risk of suffering some types of cancer, such as breast and endometrial cancer, but further studies are needed to confirm these results. Modified from Mace et al. In some cases the purported effect may depend on external cues, such as the amount of moonlight. The results showed no significant association between isoflavone consumption and gastric cancer risk, with the highest (0.675.5 mg/day) versus the lowest (0.0120.1 mg/day) categories of dietary isoflavone intake. However, a limitation in this field is that there is still a great heterogeneity among studies. With regard to the published meta-analysis, the studies included were restricted to randomized controlled trials. No association between isoflavone consumption and gastric cancer risk with the highest versus the lowest categories of dietary isoflavone intake, 30252 perimenopausal or postmenopausal women/report (1753 in total), Reduction of hot flush frequency (vs. placebo), Slight and slow attenuation of hot flushes (vs. estradiol), Slight and slow attenuation of hot flushes (vs. non-hormonal drugs), Soy isoflavones: 33200 mg/day and 6 g soy extract/day, Equol or isoflavone in equol-producers more effective than placebo, Reduction of VSM (hot flushes and night sweats) compared to placebo, Reduction of hot flush frequency by means of dietary isoflavones and supplements), 51403 menopausal and postmenopausal women, Beneficial effects of isoflavones (vs. placebo), 40403 menopausal and postmenopausal women. Soy products (0.05130 g/day) and total isoflavones (0.28 to 63 mg/day). Acid rain also removes minerals and nutrients from the soil that trees need to grow. The most significant food source of isoflavones in humans is soy-derived products, soybeans, soy flour, soy flakes, soy beverages and fermented soy products such as miso and tempeh, among others [9]. Messina M.J. Legumes and soybeans: Overview of their nutritional profiles and health effects. The effect of the moon on planting times is stated as a matter of fact in such popular publications as The Old Farmer's Almanac and books such as Gardening and Planting by the Moon 2018, and, of course, calendars such as The Biodynamic Sowing and Planting Calendar 2018. Non-pharmacological treatments included isoflavones, which appeared to be better than placebo in the relief of vasomotor symptoms, although not significantly better than the treatment with estradiol and progesterone. In contrast, red clover was not associated with changes in the hot flush frequency. In this revision, three systematic reviews and five meta-analyses were included to explore the association of isoflavones and markers related to CVDs (Table 3). ; WritingOriginal Draft Preparation, S.G.-Z., M.G.-A., A.F.-Q., I.E. ); sue.uhe@zelaznog.enatiam (M.G.-A. Another meta-analysis, conducted by Zhao et al. In the meta-analysis reported by Chen et al. Hua et al. (2015), the authors examined the efficacy of phytoestrogens in reducing hot flushes [86]. However, all the authors agree that further studies are necessary so as to confirm these results. In the end, isoflavones could be useful in reducing hot flushes associated with menopause. Arjmandi B.H., Smith B.J. (2016) published another systematic review of 23 randomized controlled trials to determine the effect of soy isoflavone extracts on bone mineral density in postmenopausal women [51]. The authors found a statistical inverse association between isoflavone consumption and colorectal cancer risk in case-control studies, although not in cohort studies. This article was originally published with the title "The Effects of Moonlight" in Scientific American 13, 37, 289 (May 1858), doi:10.1038/scientificamerican05221858-289, Daryl G. Kimball and Frank von Hippel | Opinion. Reduction of the endometrial thickness in North American women (for 0.23 mm). In view of the results gathered in the present review, we can conclude that there is scientific evidence that reveals the beneficial effect of isoflavones on bone health and thus in the prevention and treatment of osteoporosis in postmenopausal women. The physical stiffening of arteries has major health implications for its connection to various adverse cardiovascular and other health outcomes such as coronary heart disease, stroke, hypertension or heart failure [66]. Additionally, Yan and co-workers, in their meta-analysis with a total of ten prospective cohorts and seven case-control studies (including 508,841 participants and 17,269 cardiovascular disease events), observed that the consumption of soy foods, but not that of isoflavones, was associated with a lower risk of total cardiovascular disease (including coronary heart disease and stroke) [57]. Federal government websites often end in .gov or .mil. Valsta L.M., Kilkkinen A., Mazur W., Nurmi T., Lampi A.M., Ovaskainen M.L., Korhonen T., Adlercreutz H., Pietinen P. Phyto-oestrogen database of foods and average intake in Finland. Hence, plants grow faster and healthier. The authors observed that soy isoflavone consumption was inversely associated with cancer deaths. Soy isoflavones consumption and risk of breast cancer incidence or recurrence: A meta-analysis of prospective studies. 2023 Scientific American, a Division of Springer Nature America, Inc. The most significant food source of isoflavones in humans is soy-derived products. Isoflavone excretion occurs mainly through urine and feces, primarily in the conjugate forms, and up to 95% takes place in 24 h [43]. and J.T. Regarding cancer, scientific evidence suggests that isoflavones could be useful in reducing the risk of suffering some types of cancer, such as breast and endometrial cancer, but further studies are needed to confirm these results. In this systematic review, 123 studies were included, with a total number of 516,330 participants. Gaya P., Medina M., Snchez-Jimnez A., Landete J.M. That aluminum may be harmful to plants as well as animals. In tropical climates meat which is exposed to the moonlight rapidly becomes putrid ; and in the Indies, the negroes who will lie sweltering and unoovered beneath the full glare of a tropical sun, carefully muffle their heads and faces when exposed to the moonbeams, which they believe will cause swelling and distortion of the features, and sometimes even blindness. THE effect of light on plant life has been the subject of many scientific investigations. Bacterial metabolites of isoflavones forming in the gut. Chalvon-Demersay T., Azzout-Marniche D., Arfsten J., Egli L., Gaudichon C., Karagounis L.G., Tom D. A Systematic Review of the Effects of Plant Compared with Animal Protein Sources on Features of Metabolic Syndrome. Therefore, the authors concluded that the intake of dietary isoflavones paid a protective role against ovarian cancer. Looking at a few examples of moonlight's. Morning 3: Temp 98.6 BP 124/83 Pulse 62 bpm. Liu J., Yuan F., Gao J., Shan B., Ren Y., Wang H., Gao Y. Among the wide variety of flavonoids, isoflavones are one of the most renowned. Sotoca A.M., van den Berg H., Vervoort J., van der Saag P., Strm A., Gustafsson J.A., Rietjens I., Murk A.J. Daidzein, genistein and glycitein occur naturally in the aglycone form, and thus their absorption is faster than that of others. Consensus: Soy isoflavones as a first-line approach to the treatment of menopausal vasomotor complaints. Overall, evidence regarding the use of isoflavones in cancer prevention suggests that they may be useful in reducing the risk of suffering from some types of cancer, such as breast and endometrial cancer, two of the types for which the association between isoflavone intake and cancer risk has been studied more in-depth. This result has implications for granivory and perhaps plant demography in invaded and restored coastal habitats. Focusing on the overall intake of isoflavones in humans, several studies have reported varied results. Thus, whereas Asian populations have an average isoflavone consumption of >30 mg/day, Western populations consume <1 mg/day [83]. Two of the studies also revealed that women who were able to produce equol or who had received equol supplementation could have had a greater benefit from isoflavones [53]. Lastly, Zhang et al. Further, Chalvon-Demersay et al. In another systematic review of three observational studies (including 68,748 participants), low evidence of isoflavones was shown in the prevention of cardiovascular diseases [61]. The effect of soy isoflavones on arterial stiffness: A systematic review and meta-analysis of randomized controlled trials. Thirty-seven articles presenting evidence of the physiological effects of viewing nature were selected. Perna S., Peroni G., Miccono A., Riva A., Morazzoni P., Allegrini P., Preda S., Baldiraghi V., Guido D., Rondanelli M. Multidimensional Effects of Soy Isoflavone by Food or Supplements in Menopause Women: A Systematic Review and Bibliometric Analysis. (2017) conducted a meta-analysis with 21 case-control studies and two cohort studies, with a total number of 11,346 cases and 140,177 controls [77]. In fact, all the body fluids, as the tides, were controlled by the lunar phases. For the development of this section, the meta-analyses and systematic reviews published between 2015 and 2020 were taken into account. All authors have read and agreed to the published version of the manuscript. Analysis of isoflavones in Foods. Bardin A., Boulle N., Lazennec G., Vignon F., Pujol P. Loss of ERbeta expression as a common step in estrogen-dependent tumor progression. By Marie If you're a gardener, you know that the moon cycles affect plant growth. Postprandial lipemia detects the effect of soy protein on cardiovascular disease risk compared with the fasting lipid profile. Association between Dietary Isoflavones in Soy and Legumes and Endometrial Cancer: A Systematic Review and Meta-Analysis. This is mainly due to their potential adverse effects, which range from increased coronary heart disease to stroke and cancer [53,85]. Similarly, Li et al. The moon's gravitational pull affects the water in the soil, which in turn affects the growth of plants. May affect males and females differently A 2015 study of 205 people found that the full moon may affect sleep differently in males and females. However, the authors acknowledged several limitations to their study, such as the small sample size in the meta-analysis (middle-aged 276 women and 209 men), and recognized that a large number of subjects as well as a lengthier intervention are needed to investigate whether supplementation of soy isoflavones actually improves these outcomes. With regard to the mechanisms by which isoflavones act to reduce cancer risk, it has been suggested that the effects are due to the similarity of the isoflavone molecule to estradiol. In conclusion, this study reported some evidence that suggests the beneficial role that daidzein and genistein play in preventing breast cancer risk. However, the authors pointed out several limitations of this study, such as the important source of heterogeneity in their study. ; Funding Acquisition, M.P.P. Estimated Asian adult soy protein and isoflavone intakes. In a study conducted by Karr et al., the authors analyzed the urinary excretion of genistein, daidzein, equol and O-DMA in fourteen young men and women [47]. Regarding endometrial cancer, three prospective and five case-control studies were analyzed, which suggested a lower endometrial cancer risk associated with isoflavone consumption. Acid rain leaches aluminum from the soil. (2016) conducted a meta-analysis aimed at ovarian cancer, which affects women exclusively [74]. In this line, another meta-analysis, which included 52 controlled trials and 5313 patients, shows that soy isoflavones have beneficial effects on bone mineral density in the femur neck, lumbar spine, and hip, regardless of body weight or ethnicity [49]. Effects of isoflavones in different cancer types. Lu L.J., Anderson K.E. Presence of four chemical forms of the three isoflavones found in soybeans. Effects of isoflavones in cardiovascular disease-related markers. Kelly G.E., Nelson C., Waring M.A., Joannou G.E., Reeder A.Y. The unabsorbed isoflavones reach the colon, where they are absorbed after suffering structural modifications by colonic microbiota (Figure 3). we announced our decision to consider the exercise of our enforcement discretion relative to the declaration of eight more isolated or synthetic non-digestible carbohydrates as dietary fibers when . Furthermore, soy protein has been linked to an improvement in nitric oxide production and contributes to increased arterial compliance [65]. Lastly, Abshirini et al. It supports the evidence that isoflavones can moderately attenuate bone resorption in women with low estrogen levels, primarily at the level of the lumbar spine and the femoral neck. 19% reduction in endometrial cancer risk. As far as the mechanisms of action involved in the decrease in triglyceride concentration are concerned, it has been reported that hepatic lipase and/or lipoprotein lipase activity may be increased as a result of isoflavone presence. A significant 19% reduction of the risk was found at high concentrations of daidzein, but not at genistein or equol concentrations. They also explained that the differences between isoflavones and the rest of the drugs might be because the latter act by modulating central neurotransmitters and, as a consequence, by regulating the central thermoregulatory centers in the hypothalamus. Soy Consumption and the Risk of Prostate Cancer: An Updated Systematic Review and Meta-Analysis. As with other phenolic compounds, isoflavones can be presented as free forms (aglycones) or conjugated with carbohydrates (glycosides). (2018) showed no effect of soy isoflavones on plasma concentrations of lipoprotein a (Lpa), a low-density lipoprotein associated with increased cardiovascular risk due to its pro-thrombotic and atherogenic properties [63]. Dead or dying trees are a common sight in areas effected by acid rain. For this reason, the bioavailability of isoflavones has been extensively characterized in animal models and humans [25,26,27]. (2016) included 17 studies (nine case-control studies and eight cohort studies) [80]. They found that the use of dietary isoflavones or supplements and extracts was associated with an improvement in hot flushes, but not with a reduction in the frequency of night sweats. The same results were reported in another meta-analysis published by the same authors a year later (Li et al., 2016), when they compared the efficacy of several non-hormonal drugs on hot flushes, including selective serotonin reuptake inhibitors (SSRIs), serotoninnorepinephrine reuptake inhibitors (SNRIs), gabapentin, clonidine and soy isoflavones [88]. Due to the high prevalence of colorectal cancer, three meta-analyses addressing this issue are included in the present review. CVD: cardiovascular disease, LDL: low-density lipoprotein. Regarding breast cancer (Table 4), the same increase in soy isoflavone intake (10 mg/day) was related to a 9% lower risk of breast cancer mortality. Vlachopoulos C., Aznaouridis K., Stefanadis C. Prediction of cardiovascular events and all-cause mortality with arterial stiffness: A systematic review and meta-analysis. Equol has been considered as the most interesting colonic metabolite due to its beneficial biological activity, which differs from that of its precursor, daidzein [13,38,39]. Nevertheless, the metabolism of formononetin and biochanin A, the main isoflavones in red clover, has been less studied due to their limited presence in foodstuffs. Prez-Cornago et al. Oral isoflavone supplementation on endometrial thickness: A meta-analysis of randomized placebo-controlled trials. "It's not. (At least not real scientists.) As in the previous study, the onset of soy isoflavones was very slow in comparison with other non-hormonal treatments. Bustamante-Rangel M., Delgado-Zamarreo M.M., Perez-Martin L., Rodriguez-Gonzalo E., Dominguez-Alvarez J. Abdi et al. (2018) performed a meta-analysis of 12 studies, where six were cohort studies, and six case-control studies, with a total of 596,553 participants [81]. Therefore, it is necessary to support these results with additional studies. Plants grow best when the moon is in the waxing phase, when its gravitational pull is strongest. Urinary isoflavonoid excretion in humans is dose dependent at low to moderate levels of soy-protein consumption. While equol production seems to be similar in animals, it is very variable in humans [41], and therefore, beneficial effects referred to equol have been observed only in individuals with a specific microbiota composition [38]. In addition, genistein and glycitein are transformed into dihydrogenistein and dihydroglycitein, respectively, before being further converted into other metabolites. Accessibility For this purpose, 23 studies with 2167 patients were included in this meta-analysis, which showed that a daily dose of more than 54 mg could decrease the endometrial thickness in North American women, whereas the contrary effect was observed in the Asian sample. An official website of the United States government. Isoflavones were the phytoestrogens used in most of the studies; therefore, the meta-analysis only included outcomes regarding isoflavones, while outcomes with other phytoestrogens were not included. Inverse association between isoflavone consumption and colorectal cancer risk in case-control studies, but not in cohort studies. Produced metabolites appear in plasma at variable concentrations and can enter enterohepatic circulation [28]. and Rossi et al. Isoflavone content in soy-derived products is usually lower than in soybeans [17]. However, when a subgroup analysis by a class of flavonoids was carried out, they concluded that these inverse associations were significant for all categories of flavonoids except for isoflavones and flavonols. EFSA Pannel on Food Additives and Nutrient Sources Added to Food (ANS) Risk assessment for peri- and post-menopausal women taking food su pplements containing isola ted isoflavones. Effects of isoflavones in bone health maintenance. Before However, a limitation in this field is that there is still a great heterogeneity among studies. Akhlaghi M., Ghasemi Nasab M., Riasatian M., Sadeghi F. Soy isoflavones prevent bone resorption and loss, a systematic review and meta-analysis of randomized controlled trials.
