Efficacy of phytoestrogens for menopausal symptoms: A meta-analysis and systematic review. Many females sleep less and have less REM sleep. 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]. However, the intake of specific isoflavones, genistein and daidzein, was indeed significantly associated with a reduced risk of this type of cancer. Treutter D. Significance of flavonoids in plant resistance and enhancement of their biosynthesis. [(accessed on 21 September 2020)]; Messina M., Nagata C., Wu A.H. Li L., Lv Y., Xu L., Zheng Q. Quantitative efficacy of soy isoflavones on menopausal hot flashes. In contrast, red clover was not associated with changes in the hot flush frequency. Others, however, consider such notions as prime examples of "New Age freakery". The authors found a statistical inverse association between isoflavone consumption and colorectal cancer risk in case-control studies, although not in cohort studies. Kim Y., Je Y. Flavonoid intake and mortality from cardiovascular disease and all causes: A meta-analysis of prospective cohort studies. They observed that daidzein and genistein intakes were associated with a significant reduction of prostate cancer risk. Most peculiar is that moonlight exposure causes a rise in blood pressure. Interestingly, soy protein isolate (void of isoflavones through alcoholic extraction during the protein solation phase) did not show these effects. Duffy C., Perez K., Partridge A. Thus, whereas Asian populations have an average isoflavone consumption of >30 mg/day, Western populations consume <1 mg/day [83]. Regarding the effect of specific isoflavones, they suggested that genistein, alone or in combination with daidzein, improved bone density and bone turnover in women after menopause. In this line, three meta-analyses were conducted to study isoflavone consumption and endometrial cancer risk. For this reason, the results should be interpreted with caution, and more randomized clinical trials are required. Winkel-Shirley B. Biosynthesis of flavonoids and effects of stress. Collison M.W. Mace T.A., Ware M.B., King S.A., Loftus S., Farren M.R., McMichael E., Scoville S., Geraghty C., Young G., Carson W.E., et al. Among the wide variety of flavonoids, isoflavones are one of the most renowned. 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]. Before In addition, it is important to highlight that interindividual differences in gut bacterial populations are responsible for the diverse effects of isoflavones in humans. Franco et al. 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. 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. Grosso et al. Modified from Wang et al., 2006 [4]. Daidzein is first converted into dihydrodaidzein, which is the precursor of both equol and O-demethylangolensin (O-DMA) [37]. Batterham T.J., Shutt D.A., Braden A.W.H., Tweeddale H.J. This fact suggests that other components, such as fiber in the soy foods, may account for these negative associations. Daidzein, genistein and glycitein occur naturally in the aglycone form, and thus their absorption is faster than that of others. They are present in several vegetables, mainly in legumes such as soy, white and red clover, alfalfa and beans. 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. Hairi H.A., Shuid A.N., Ibrahim N., Jamal J.A., Mohamed N., Mohamed I.N. The authors found, in a small number of studies (17 studies including 337 healthy, diabetic or hypercholesterolemic individuals), that a soy protein-based diet (rich in isoflavones) as compared to animal protein-based diets (meat, milk, casein, whey) resulted in reduced total cholesterol or LDL-cholesterol concentrations, increased HDL cholesterol concentrations, improved LDL:HDL cholesterol ratio, and decreased triglycerides. According to the results gathered in the present review, it can be stated that there is scientific evidence showing the beneficial effect of isoflavones on bone health and thus in the prevention and treatment of osteoporosis on postmenopausal women, although the results do not seem entirely conclusive as there are discrepancies among the studies, probably related to their experimental designs. Study duration ranged from four weeks to two years, with a median of 12 weeks. For this reason, the bioavailability of isoflavones has been extensively characterized in animal models and humans [25,26,27]. Ronis M.J., Little J.M., Barone G.W., Chen G., Radominska-Pandya A., Badger T.M. Bhathena S.J., Velasquez M.T. . (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]. 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. The aim of the present review is to gather the scientific evidence existing nowadays on the main beneficial effects of isoflavones on health: bone health, cardiovascular risk, cancer and menopausal symptoms. Ko K.P., Kim C.S., Ahn Y., Park S.J., Kim Y.J., Park J.K., Lim Y.K., Yoo K.Y., Kim S.S. Regarding the mechanisms by which isoflavones act to alleviate vasomotor symptoms, is has been proposed that they bind to estrogen receptors and activate endothelial nitric oxide synthase (eNOS) transcription, leading to eNOS synthesis and nitric oxide production, the main mediator of vasodilatation, which allows cutaneous heat dissipation [91] (Figure 6). Isoflavone Supplements for Menopausal Women: A Systematic Review. The Effects and Action Mechanisms of Phytoestrogens on Vasomotor Symptoms During Menopausal Transition: Thermoregulatory Mechanism. Association of isoflavone biomarkers with risk of chronic disease and mortality: A systematic review and meta-analysis of observational studies. Apparently, soy isoflavones modified adhesion molecules by binding to vascular endothelium and mimicking the effect of a modulator of estrogen receptors [64]. (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]. Analysis of isoflavones in Foods. 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. Hua X., Yu L., You R., Yang Y., Liao J., Chen D. Association among Dietary Flavonoids, Flavonoid Subclasses and Ovarian Cancer Risk: A Meta-Analysis. (2019) conducted a meta-analysis where 23 prospective studies with a total of 330,826 participants were included. In addition, Qiu et al. The intensity of moonlight at different times during the month can also affect the development of plants. These positive effects were associated with 54 mg/day of genistein and 600 mg/day of synthetic isoflavone ipriflavone. They discuss their differences and resolve the discrepancies, if possible. Finally, isoflavones could be useful in reducing hot flushes associated with menopause. 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. Rizzo G., Baroni L. Soy, Soy Foods and Their Role in Vegetarian Diets. Among these, vasomotor symptoms comprising hot flushes and night sweats are the most common and bothersome, which, in turn, have a negative impact on womens quality of life. Prospective study on usual dietary phytoestrogen intake and cardiovascular disease risk in Western women. However, some limitations were found in these prospective studies, such as the small sample size of the cohorts and the unspecific definition of high, moderate and low isoflavone intake. That's what behavioral ecologist Jenny York learned while studying white-browed sparrow weavers . Even though red clover has a greater amount of isoflavones, it is not an edible plant, and it is consumed as a food complement. Isoflavones (high dose: 0.675.5 mg/day; and low dose: 0.0120.1 mg/day). The enzyme lactase-phlorizin hydrolase (LPH) deglycosylases phenolic compounds in the intestinal lumen, and after that, the aglycone form enters the epithelial cells by passive diffusion. Bustamante-Rangel M., Delgado-Zamarreo M.M., Perez-Martin L., Rodriguez-Gonzalo E., Dominguez-Alvarez J. Jun S., Shin S., Joung H. Estimation of dietary flavonoid intake and major food sources of Korean adults. 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. Careers, Unable to load your collection due to an error. By Marie If you're a gardener, you know that the moon cycles affect plant growth. Focusing on the overall intake of isoflavones in humans, several studies have reported varied results. Micek A., Godos J., Brzostek T., Gniadek A., Favari C., Mena P., Libra M., Del Rio D., Galvano F., Grosso G.

Soy, Soy Isoflavones, and Protein Intake in Relation to Mortality from All Causes, Cancers, and Cardiovascular Diseases: A Systematic Review and Dose-Response Meta-Analysis of Prospective Cohort Studies. Four meta-analyses have been reported to address this issue. 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. Chemical structure of 17-estradiol. The authors studied all possible correlations between isoflavone consumption and the risk of breast cancer. 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]. 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. 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]. Metabolism of intraruminally administered [4-. 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. However, the moonlight decreases after the full moon. (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]. Due to the high prevalence of colorectal cancer, three meta-analyses addressing this issue are included in the present review. 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. Hua et al. Opposite effect in Asian women, Prospective studies (3) Case-control studies (5), Isoflavone consumption (>45 mg/day among the Asian population, and >1 mg/day among the non-Asian population), Potential reduction risk associated with isoflavone consumption, Prospective cohort study (5) Case-control study (7), Cohort prospective study (2 studies from Japan and 5 studies from Europe), 241 cases and 503 controls (from Japanese studies), and 2828 cases and 5593 controls (from European studies), Circulating isoflavone concentrations (nmol/L): Daidzein (Japanese: 115166; European: 2.843.96), Genistein, daidzein and equol did not affect prostate cancer risk in both Japanese and European men, Case-control study (15) Cohort study (8) Nested case-control study (7), 266,699 (21,612 patients with prostate cancer), Isoflavones were not associated with a reduction of prostate cancer risk, Daidzein, genistein, and equol (dose not defined), 19% reduction in prostate cancer risk was found at high concentrations of daidzein, but not with genistein or equol, Participants: 11,346 cases and 140,177 controls, Daidzein and genistein intakes were associated with a reduction of prostate cancer risk (no effect with equol), 559,486 (among them 16,917 colorectal cancer cases), Foods rich in isoflavones (dose not defined), Soy foods (30 mg/day170 g/day) and isoflavones (0.01460 mg/day). Moreover, Rienks et al. For their meta-analysis, Jiang et al. Endometrial cancer (Table 4), as well as breast cancer, is an estrogen-dependent cancer type related to high circulating estradiol concentrations. Karr S.C., Lampe J.W., Hutchins A.M., Slavin J.L.

Developmental and Reproductive Effects of SE5-OH: An Equol-Rich Soy-Based Ingredient. As it has been stated in the Bioavailability section, microbiota composition in humans makes equol production very variable, which yields high interindividual differences. http://creativecommons.org/licenses/by/4.0/, https://data.nal.usda.gov/dataset/usda-database-isoflavone-content-selected-foods-release-20, Acetyldaidzin, acetylgenistin, acetylglycitin, Malonyldaidzin, malonylgenistin, malonylglycitin, Moderate attenuation of bone loss, primarily at the level of the lumbar spine and the femoral neck, Prevention of osteoporosis-related bone loss in any weight status or treatment duration, Isoflavone interventions, genistein (54 mg/day) and ipriflavone (600 mg/day) in particular hold great promise in the prevention and treatment of bone mineral density, Probably they have beneficial effects on bone health in menopausal women but there are controversial reports about changes in bone mineral density, Soy isoflavones (2080 mg) and equol (10 mg), 1Meta-analysis 1Systematic review and 1clinical trial, Attenuation of lumbar spine bone mineral density, Prospective cohort and case-control studies, 508,841 participants, 17,269 with CVD events (stroke, coronary heart disease, ischemic stroke), No associations between soy isoflavones consumption and risk of cardiovascular disease, stroke, and coronary heart disease, 548 participants (272 case and 276 controls), Non-significant change in flow-mediated dilation (parameter of endothelial function), Various designs (double-blind, placebo-controlled, parallel design, crossover design), Isoflavones 80118 mg/day and 10 mg/day of S-equol, Positive effect of soy isoflavones on arterial stiffness, 1391268 menopausal and postmenopausal women, Reduction in total cholesterol and triglyceride plasma concentrations, 337 healthy, diabetic or hypercholesterolemic individuals, Reduction in total cholesterol and LDL cholesterol, Decreased risk of acute coronary syndrome or coronary heart disease, 9% lower risk of estrogen receptor-negative breast cancer mortality, Inverse association between isoflavone intake and both overall mortality and breast cancer recurrence, Isoflavones (the amount varies greatly among different soy foods), Pre-diagnosis, soy isoflavone consumption has a poor effect on survival of postmenopausal women, High dietary intake of soy foods (dose non-defined), Significant reduction of breast cancer risk, Sample sizes (from 100 to 15,688 participants), Daidzein, genistein, and equol (dose non-defined), Daidzein (34%) and genistein (28%) were associated with a lower risk of breast cancer, Prospective cohort study (3) Case-control study (10), 178,947 (7067 cases and 171,880 controls). 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]. To address the link between lunar phases and agriculture from a scientic perspective, we conducted a review of textbooks and monographs used to teach agronomy, botany, horticulture and plant physiology; we also consider the physics that address the e ects of the Moon on our planet. Neuroprotective effects of 17beta-estradiol and nonfeminizing estrogens against H. Endoh H., Sasaki H., Maruyama K., Takeyama K., Waga I., Shimizu T., Kato S., Kawashima H. Rapid activation of MAP kinase by estrogen in the bone cell line. 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 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. 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. (2016), nine studies addressed to menopausal women and focused on bone health were analyzed [52]. (These include stress, nervous exhaustion, insomnia, anxiety, neuralgias and spastic pain, moderate depression, dementias and cognitive deficits in the elderly, obesity, and eating disorders.) Although results vary greatly, most of these applications are supported by at least a few clinical studies. 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]. Effect of soy isoflavone supplementation on plasma lipoprotein(a) concentrations: A meta-analysis. In the meta-analysis reported by Chen et al. Soy isoflavones osteoprotective role in postmenopausal women: Mechanism of action. Rossi M., Amaretti A., Roncaglia R., Leonardi A., Raimondi S. Dietary isoflavones and dietary microbiota: Metabolism and transformation into bioactive compounds. The latter is the most common form in foodstuffs, with the exception of fermented soy products, such as miso and tempeh. 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. Nevertheless, this association was not shown when equol or isoflavones were consumed. Zhong X.S., Ge J., Chen S.W., Xiong Y.Q., Ma S.J., Chen Q. Regarding blood pressure, inconsistent results were reported in three further interventional studies (n = 406 healthy, postmenopausal or obese participants aged 5079 years) either in diastolic or systolic blood pressure, after a supplementation with soy-protein. U.S. Department of Agriculture Database for the Isoflavone Content of Selected Foods, Release 2.0. Yu Y., Jing X., Li H., Zhao X., Wang D. Soy isoflavone consumption and colorectal cancer risk: A systematic review and meta-analysis. Isoflavone glycosides have to be hydrolyzed to the aglycone form prior to its absorption by passive diffusion in the upper small intestine [28]. The light of the moon also influences animals that are active in daytime. Sansai K., Na Takuathung M., Khatsri R., Teekachunhatean S., Hanprasertpong N., Koonrungsesomboon N. Effects of isoflavone interventions on bone mineral density in postmenopausal women: A systematic review and meta-analysis of randomized controlled trials. 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]. So long ago as 1880 Siemens showed that continuous exposure to arc lamps promoted luxuriance of foliage . 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. Intestinal transport of quercetin glycosides in rats involves both deglycosylation and interaction with the hexose transport pathway. This fact was not taken into account in previous meta-analyses, and thus it may justify the discrepancies amongst them. (At least not real scientists.) The results indicated that the isoflavone intake decreased the ovarian cancer risk by 33%. Daily et al. 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. Moreover, the number of publications grouping women according to pre- or post-diagnosis intake criteria is small. In miso and tempeh, the aglycone form is the most abundant one [9]. Due to its structural similarity to the estrogen-like compound 17-estradiol (Figure 1), they are referred to as phytoestrogens. Equol is produced from the isoflavone daidzein by intestinal bacteria, mainly in the large intestine. Hosoda K., Furuta T., Yokokawa A., Ishii K.

(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]. That aluminum may be harmful to plants as well as animals. You J., Sun Y., Bo Y., Zhu Y., Duan D., Cui H., Lu Q. Contraction stimulates translocation of glucose transporter GLUT4 in skeletal muscle through a mechanism distinct from that of insulin. Man B., Cui C., Zhang X., Sugiyama D., Barinas-Mitchell E., Sekikawa A. Acid rain leaches aluminum from the soil. They observed that it was dose-dependent at low to moderate soybean consumption. Isoflavones are found in several vegetables, mainly in legumes (Fabaceae family) such as soy, white and red clover, alfalfa and beans [9,10]. Some authors label equol as an isoflavone; however, since it is a daidzein-derived bacterial metabolite and not a naturally occurring isoflavone, this classification is not correct [10]. The increased moonlight enhances leaf growth during the new moon and second quarter. 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. Sotoca A.M., van den Berg H., Vervoort J., van der Saag P., Strm A., Gustafsson J.A., Rietjens I., Murk A.J. From laboratory experiments, it's known that light intensities as low as 0.1 lux (approximately 0.01 foot-candle) during the night can influence photoperiodic time measurement in some plants and animals. 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. The results showed that a higher regular intake of foods rich in isoflavones might potentially decrease colorectal cancer incidence. Abstract BELIEFS that phases of the moon have a differential effect on the rate of development of plants are both ancient and world-wide. Similarly, Li et al. Dead or dying trees are a common sight in areas effected by acid rain. 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. Sirotkin A.V., Harrath A.H. Phytoestrogens and their effects. While a moderate intake of soy isoflavones did not significantly affect breast cancer risk, a significant reduction was shown when the intake was high. Isoflavone intake in four different European countries: The VENUS approach. Sulfation of the isoflavones genistein and daidzein in human and rat liver and gastrointestinal tract. and J.T. They also note that the effects of isoflavones are greater when administered as aglycones. Phytoestrogen Metabolism by Adult Human Gut Microbiota. and transmitted securely. However, it is important to point out that the beneficial effects of soy isoflavone consumption have been exhibited by women with estrogen receptor-negative breast cancer, but not by women with receptor-positive breast cancer, who present a better prognosis [62].
