On the contrary, women who were already equol producers did not obtain any additional benefit from supplements of equol or isoflavones. However, the magnitude of risk reduction in Asian women was slightly larger than in non-Asian women (22% vs. 18%). By contrast, it seems that soy isoflavones do not lead to a meaningful protective effect on cardiovascular risk. Isoflavone intake in four different European countries: The VENUS approach. Is equol production beneficial to health? Most would agree that the daily rising and falling of the moon, along with the monthly waxing and waning cycles, have effects on our oceans and seas. Lastly, Zhang et al. For their meta-analysis, Jiang et al. Kelly G.E., Nelson C., Waring M.A., Joannou G.E., Reeder A.Y. 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. Circulating isoflavone and lignan concentrations and prostate cancer risk: A meta-analysis of individual participant data from seven prospective studies including 2,828 cases and 5,593 controls. 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]. Sarri G., Pedder H., Dias S., Guo Y., Lumsden M.A. The authors studied all possible correlations between isoflavone consumption and the risk of breast cancer. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. Efficacy of phytoestrogens for menopausal symptoms: A meta-analysis and systematic review. Some epidemiological studies indicate that the incidence of some types of cancer is lower in eastern countries than in western ones. 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. Diversely, Liu et al. They are present in several vegetables, mainly in legumes such as soy, white and red clover, alfalfa and beans. Moreover, an increase in thyroid hormone levels after isoflavone intake by food supplements has not been observed, and no side effects were confirmed with regard to the endometrial thickness or histopathological changes in the uterus. The lunar effect is a purported unproven correlation between specific stages of the roughly 29.5-day lunar cycle and behavior and physiological changes in living beings on Earth, including humans. HHS Vulnerability Disclosure, Help Therefore, it is necessary to support these results with additional studies. During menopause, there is a loss of bone density that can cause osteoporosis. 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. Moreover, five studies reported side-effect data, and after the analysis, no significant differences were observed between the two groups. Reproductive and developmental toxicity studies have stated that 1 g and 2 g of equol per day is safe [96], although further studies are required [92]. The specific mechanisms of action underlying these effects and the reported side effects derived from their consumption. Hormone replacement therapy has been proven to be effective in reducing vasomotor symptoms, although isoflavones have gained popularity as an alternative treatment to hormone replacement therapy to relieve menopausal symptoms. 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]. So long ago as 1880 Siemens showed that continuous exposure to arc lamps promoted luxuriance of foliage . Barnes S. The biochemistry, chemistry and physiology of the isoflavones in soybeans and their food products. Concerning this issue, six meta-analyses and two systematic reviews are included in the present review (Table 5). Isoflavones have received attention due to their putative healthy properties. Lambert M.N.T., Hu L.M., Jeppesen P.B. For this reason, the results should be interpreted with caution, and more randomized clinical trials are required. Their meta-analysis included five studies with a total of 728 menopausal women between 50.5 and 58.5 years old and concluded that women who are not able to produce equol could benefit from equol supplementation. Federal government websites often end in .gov or .mil. However, all the authors agree that further studies are necessary so as to confirm these results. Chang H.H., Robinson A.R., Common R.H. Excretion of radioactive diadzein and equol as monosulfates and disulfates in the urine of the laying hen. ); sue.uhe@zelaznog.enatiam (M.G.-A. Lu L.J., Anderson K.E. (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]. This is mainly due to their potential adverse effects, which range from increased coronary heart disease to stroke and cancer [53,85]. With regard to the published meta-analysis, the studies included were restricted to randomized controlled trials. 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. Presence of four chemical forms of the three isoflavones found in soybeans. PV panels have been linked . (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]. Nevertheless, it is important to consider this metabolite since it is key in the biological activity of isoflavones [13]. Micek A., Godos J., Brzostek T., Gniadek A., Favari C., Mena P., Libra M., Del Rio D., Galvano F., Grosso G.

Effects of isoflavone interventions on bone mineral density in postmenopausal women: A systematic review and meta-analysis of randomized controlled trials. Franco et al. In fact, the number of isoflavones present was very variable among the different soy food types. Batterham T.J., Shutt D.A., Braden A.W.H., Tweeddale H.J. In fact, in 2015, in relation to the possible adverse effects on the mammary gland, uterus and thyroid, the European Food Safety Agency (EFSA) offered a scientific opinion with regards to the assessment of potential increased risk in peri- and postmenopausal women who took food supplements that contained isolated isoflavones. Hua et al. Isoflavones could be used as an alternative therapy for pathologies dependent on hormonal disorders such as breast and prostate cancer, cardiovascular diseases, as well as to minimize menopausal symptoms. Nevertheless, the results do not seem entirely conclusive, as there are discrepancies among the studies included in the systematic reviews and in the meta-analyses, probably related to their experimental designs. In this sense, it has been described that both isoflavones and other estrogenic molecules could mediate their beneficial effects due to two different mechanisms: the classical estrogen receptor (ER)-mediated signaling pathway and the activation of intracellular pathways such as protein tyrosine kinase, phospholipase C and mitogen-activated protein kinase (MAPK) [5,6]. Thus, the EFSA scientific committees opinion agreed that isoflavone intake was safe, at least in the doses that the analyzed studies have used. In miso and tempeh, the aglycone form is the most abundant one [9]. . Saloniemi H., Whl K., Nyknen-Kurki P., Kallela K., Saastamoinen I. Phytoestrogen content and estrogenic effect of legume fodder. However, more studies are required to provide stronger evidence. 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. Despite the positive effect of isoflavones, the authors emphasized that the effects took a long time to appear. The latter is the most common form in foodstuffs, with the exception of fermented soy products, such as miso and tempeh. (2017) included 26 trials with 2652 participants [48]. Contraction stimulates translocation of glucose transporter GLUT4 in skeletal muscle through a mechanism distinct from that of insulin. Analysis of isoflavones in Foods. Although smaller in quantity, isoflavones are also present in chickpeas, nuts, fruits and vegetables [11]. In the same line, Yu 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]. 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. (2016), nine studies addressed to menopausal women and focused on bone health were analyzed [52]. Rizzo G., Baroni L. Soy, Soy Foods and Their Role in Vegetarian Diets.

Bardin A., Boulle N., Lazennec G., Vignon F., Pujol P. Loss of ERbeta expression as a common step in estrogen-dependent tumor progression. The results indicated that the isoflavone intake decreased the ovarian cancer risk by 33%. 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. In the systematic review reported by Perna et al.

Chadha R., Bhalla Y., Jain A., Chadha K., Karan M. Dietary Soy Isoflavone: A Mechanistic Insight. The most significant food source of isoflavones in humans is soy-derived products. Thirty-seven articles presenting evidence of the physiological effects of viewing nature were selected. (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]. He X., Sun L.M. Endometrial cancer (Table 4), as well as breast cancer, is an estrogen-dependent cancer type related to high circulating estradiol concentrations. Association between Dietary Isoflavones in Soy and Legumes and Endometrial Cancer: A Systematic Review and Meta-Analysis. Soy isoflavones and their metabolites modulate cytokine-induced natural killer cell function. Winkel-Shirley B. Biosynthesis of flavonoids and effects of stress. Li L., Xu L., Wu J., Dong L., Zhao S., Zheng Q. The difference for isoflavones required to find an effect can be due to variations in the amount of isoflavone intake between both populations. In this study, five prospective cohort studies and seven case-control studies, with 6275 cases and 393,776 controls, were included. Although the mechanisms of action of isoflavones are not completely understood, it seems that isoflavones not only reduce the rate of bone resorption but also increase the rate of bone formation. Consequently, isoflavones can have estrogenic or anti-estrogenic effects [3]. and J.T. Due to the high prevalence of colorectal cancer, three meta-analyses addressing this issue are included in the present review. All authors have read and agreed to the published version of the manuscript. Background Climate change and the current phase-out of fossil fuel-fired power generation are currently expanding the market of renewable energy and more especially photovoltaic (PV) panels. aimed to compare the effects of animal and plant-sourced proteins on lipemia and blood pressure [60]. Produced metabolites appear in plasma at variable concentrations and can enter enterohepatic circulation [28]. The authors suggested that this difference could be due to different genetic backgrounds and dietary patterns among Asian and Western populations. At high elevations, acidic fog and clouds might . In like manner, a meta-analysis by Simental-Menda et al. 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. Scientists often disagree about certain things. 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. 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. Conceptualization, S.G.-Z. Similarly, Li et al. (2017) carried out a meta-analysis of 143 case-control studies, where isoflavone intake was associated with endometrial, ovarian, and breast cancers [73]. Soy products (0.05130 g/day) and total isoflavones (0.28 to 63 mg/day). This fact was not taken into account in previous meta-analyses, and thus it may justify the discrepancies amongst them. Another meta-analysis explored the effects of several pharmacological and non-pharmacological treatments in the relief of vasomotor symptoms, taking into account not only hot flushes but also night sweats [89]. Proof by rational experiment seems to have been. However, the authors suggested that more prospective cohort studies are needed to further investigate this association and that the quantity of isoflavone intake should be accurately measured because flavonoid contents in food can vary significantly. The main isoflavones found in foodstuffs are daidzein, genistein and glycitein, as well as biochanin A and formononetin [9,12]. Zhong et al. As with other phenolic compounds, isoflavones can be presented as free forms (aglycones) or conjugated with carbohydrates (glycosides). As previously mentioned, soybeans and their derived foodstuffs are the main isoflavone sources in the human diet, at least if we do not consider red clover extract supplements, which are being widely used by menopausal women as nutraceutical therapy [13].

Specifically, the time to achieve half of the efficacy was 11.6 weeks for soy isoflavones, while for the rest of the compounds, the onset time was near 0 weeks. When a group receiving hormone replacement therapy was included in the study, significant differences between the effects of hormone replacement therapy and soy were found, being the effect of the former superior to that of isoflavones. This meta-analysis included 266,699 participants (21,612 patients with prostate cancer among them). An official website of the United States government. Soy isoflavones consumption and risk of breast cancer incidence or recurrence: A meta-analysis of prospective studies. Day A.J., Caada F.J., Daz J.C., Kroon P.A., Mclauchlan R., Faulds C.B., Plumb G.W., Morgan M.R., Williamson G. Dietary flavonoid and isoflavone glycosides are hydrolysed by the lactase site of lactase phlorizin hydrolase. Furthermore, soy protein has been linked to an improvement in nitric oxide production and contributes to increased arterial compliance [65]. Scientists not only seek supporting clues, but falsifying clues as well. Furthermore, among the four studies of breast cancer recurrence, three studies found that isoflavone intake decreased the risk of breast cancer recurrence, although further studies are required to confirm this finding [82]. Others, however, consider such notions as prime examples of "New Age freakery". Dietary polyphenol intake in Europe: The European Prospective Investigation into Cancer and Nutrition (EPIC) study. Perez-Cornago A., Appleby P.N., Boeing H., Gil L., Kyr C., Ricceri F., Murphy N., Trichopoulou A., Tsilidis K.K., Khaw K.T., et al. Professor Piazza Smyth, the Astronomer Royal for Scotland, in his interesting account of a recent scientific expedition made by him to the Peak of Teneriffe, has set at rest the vexed question of the heat of the moonlight. The enhanced bone formation is due to the stimulation of osteoblastic activity mainly through (a) the activation of estrogen receptors because they bind to nuclear estrogen receptors and exhibit estrogenic activity due to its similarity to 17-estradiol, and (b) the promotion of insulin-like growth factor-I (IGF-I) production [54,55] (Figure 4). In addition, it is important to highlight that interindividual differences in gut bacterial populations are responsible for the diverse effects of isoflavones in humans. The meta-analysis included 15 studies in which the number of participants ranged from 30 to 252. Moreover, this association was more prominent among postmenopausal women than premenopausal women. By contrast, it seems that soy isoflavones do not lead to a meaningful protective effect on cardiovascular risk. Murota K., Nakamura Y., Uehara M. Flavonoid metabolism: The interaction of metabolites and gut microbiota. 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. The Effects and Action Mechanisms of Phytoestrogens on Vasomotor Symptoms During Menopausal Transition: Thermoregulatory Mechanism. Regarding endometrial cancer, three prospective and five case-control studies were analyzed, which suggested a lower endometrial cancer risk associated with isoflavone consumption. Finally, isoflavones could be useful in reducing hot flushes associated with menopause. The aglycone and conjugate forms of genistein represent up to 60% of total isoflavones, this being up to 30% in the case of daidzein. The .gov means its official. Gruber C.J., Tschugguel W., Schneeberger C., Huber J.C. Production and actions of estrogens. However, the intake of specific isoflavones, genistein and daidzein, was indeed significantly associated with a reduced risk of this type of cancer. Vlachopoulos C., Aznaouridis K., Stefanadis C. Prediction of cardiovascular events and all-cause mortality with arterial stiffness: A systematic review and meta-analysis. Finally, it is important to mention that despite the fact that potential isoflavone adverse effects have been widely studied, little is known about the side effect of the bacterial metabolite equol. ); sue.uhe@zednanref.oderfla (A.F.-Q. (2018), 30 articles were included for analysis; 15 of them were case-control studies, eight cohort studies and seven nested case-control studies [76]. It follows that additional high-quality, large-scale randomized controlled trials are needed. Rienks J., Barbaresko J., Nthlings U. Moreover, a higher intake of soy isoflavones was associated with a lower risk of mortality from gastric, colorectal, and lung cancers. The authors found a significant inverse association between isoflavone intake and both overall mortality and breast cancer recurrence. Furthermore, isoflavones are associated with proteins; thus, alcohol extraction and processing diminish isoflavone content in foodstuffs such as fermented soybean, tofu or soy beverages. However, there is still a great heterogeneity among studies, which makes the current data inconclusive. Moreover, even though the binding affinity of isoflavones to the ER receptors is less than that of 17-estradiol, they can also act as estrogenic compounds when the endogenous estradiol is not available [8]. van Erp-Baart M.A., Brants H.A., Kiely M., Mulligan A., Turrini A., Sermoneta C., Kilkkinen A., Valsta L.M. The water in the ocean on the side of the Earth closest to the moon experiences a larger gravitational attraction than the water on the opposite side. (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]. Messina M.J. Legumes and soybeans: Overview of their nutritional profiles and health effects. They observed that it was dose-dependent at low to moderate soybean consumption. Four meta-analyses have been reported to address this issue. 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). Inverse association between isoflavone consumption and colorectal cancer risk in case-control studies, but not in cohort studies. He Bays that his thermometrical instruments were sensibly affected by the moon's rays, even at the lowest of two stations occupied by him at different elevations. (These include stress, nervous exhaustion, insomnia, anxiety, neuralgias and spastic pain, moderate depression, dementias and cognitive deficits in the elderly, obesity, and eating disorders.) In general terms, it has been observed that in Asian countries where there is high consumption of soy and its derived foodstuffs, isoflavone intake is high, ranging from 15 to 60 mg/day [20,21], whereas, in western countries, it is notably lower, around 12 mg/day [22,23,24]. 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. ; Funding Acquisition, M.P.P. In a study reported by Ko et al., the authors quantified the plasma concentrations of daidzein, genistein, glycitein and equol in Korean men and women [36].
