Is equol production beneficial to health? Effects of Acid Rain on Plants and Trees. 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). 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. Further, Chalvon-Demersay et al. Contrary to other types of renewable energies, such as wind and hydroelectricity, evidence on the effects of PV panels on biodiversity has been building up only fairly recently. Jun S., Shin S., Joung H. Estimation of dietary flavonoid intake and major food sources of Korean adults. The latter is the most common form in foodstuffs, with the exception of fermented soy products, such as miso and tempeh. For this reason, the results should be interpreted with caution, and more randomized clinical trials are imperative. In addition, several studies have observed that the urine excretion of daidzein metabolites is notably higher than that of genistein metabolites [44,45,46]. Lastly, the association between dietary isoflavone intake and the risk of developing gastric cancer has also been analyzed. "It's not. (2018) published a meta-analysis of seven prospective cohort studies (two studies from Japan with 241 cases and 503 controls, and five studies from Europe with 2828 cases and 5593 controls) [75]. Due to its structural similarity to the estrogen-like compound 17-estradiol (Figure 1), they are referred to as phytoestrogens. Despite the positive effect of isoflavones, the authors emphasized that the effects took a long time to appear. Thanks for reading Scientific American. Even though red clover has a greater amount of isoflavones, it is not an edible plant, and it is consumed as a food complement. The meta-analysis included 15 studies in which the number of participants ranged from 30 to 252. Soy Consumption and the Risk of Prostate Cancer: An Updated Systematic Review and Meta-Analysis. 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). (2019) conducted a meta-analysis where 23 prospective studies with a total of 330,826 participants were included. In the same line, in European men, isoflavone concentrations did not affect the risk of developing prostate cancer. Potential health adverse effects in the intake of isoflavones have been postulated due to their estrogenic activity, especially in relation to breast cancer. However, the results do not seem entirely conclusive, for there are discrepancies among the studies, probably related to their experimental designs. Moreover, Rienks et al. All authors have read and agreed to the published version of the manuscript. 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. (2019) studied whether equol supplementation could benefit equol nonproducer subjects in lowering the incidence and severity of hot flushes [85]. (2017) also analyzed eight studies of prostate cancer, and they found an association between isoflavone intake and prostate cancer risk [61]. HRT: hormone replacement therapy, RCT: randomized controlled trial, VSM: vasomotor symptoms. Thus, whereas Asian populations have an average isoflavone consumption of >30 mg/day, Western populations consume <1 mg/day [83]. The .gov means its official. He X., Sun L.M. Knowledge awaits. 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. Possible mechanism of action of isoflavones for menopausal symptoms. As it has been stated in the Bioavailability section, microbiota composition in humans makes equol production very variable, which yields high interindividual differences. 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. Franco et al. 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. The four chemical forms of the three most abundant isoflavones. At high elevations, acidic fog and clouds might . Endometrial cancer (Table 4), as well as breast cancer, is an estrogen-dependent cancer type related to high circulating estradiol concentrations. aimed to compare the effects of animal and plant-sourced proteins on lipemia and blood pressure [60]. Estimated Asian adult soy protein and isoflavone intakes. 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. 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]. (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]. Barnes S. The biochemistry, chemistry and physiology of the isoflavones in soybeans and their food products. 19% reduction in endometrial cancer risk. By contrast, the total isoflavone amount is high in soy flour, protein isolate or edamame [19]. Schmidt M., Arjomand-Wlkart K., Birkhuser M.H., Genazzani A.R., Gruber D.M., Huber J., Klbl H., Kreft S., Leodolter S., Linsberger D., et al. Nevertheless, this association was not shown when equol or isoflavones were consumed. Indeed, Kim and Je (2017) indicated that a high intake of flavonoids is associated with a reduced risk of mortality from cardiovascular diseases in men and women [56]. 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. In addition, Qiu et al. 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]. In a more recent systematic review, including two meta-analyses, as well as one multicenter and randomized controlled trial, Chen and his team concluded that isoflavones reduced lumbar spine bone mineral density loss [53]. Rizzo G., Baroni L. Soy, Soy Foods and Their Role in Vegetarian Diets. 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. 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. Thus, its consumption, according to epidemiological and clinical studies, has been postulated to be related to a decrease in the risk of different diseases. The work reported by Lambert et al. Determination of total soy isoflavones in dietary supplements, supplement ingredients, and soy foods by high-performance liquid chromatography with ultraviolet detection: Collaborative study. 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. Dong J.Y., Qin L.Q. ); sue.uhe@ollitrop.yupairam (M.P.P. Grosso et al. Changes to Earth's climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets are shrinking, river and lake ice is breaking up earlier, plant and animal geographic ranges are shifting, and plants and trees are blooming sooner. and Rossi et al. sharing sensitive information, make sure youre on a federal As in the case of other phenolic compounds, genistein and daidzein undergo phase II xenobiotic metabolism, mainly glucuronidation and sulfation reactions at 4and/or 7 positions of the isoflavone ring [34,35]. An official website of the United States government. Sarri G., Pedder H., Dias S., Guo Y., Lumsden M.A. The difference for isoflavones required to find an effect can be due to variations in the amount of isoflavone intake between both populations. Heinonen S., Whl K., Adlercreutz H.

Isoflavones (high dose: 0.675.5 mg/day; and low dose: 0.0120.1 mg/day). Plasma isoflavone concentration is associated with decreased risk of type 2 diabetes in Korean women but not men: Results from the Korean Genome and Epidemiology Study. In fact, all the body fluids, as the tides, were controlled by the lunar phases. 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]. (2019), included 16 prospective cohort studies involving 11,169 breast cancer cases and 648,913 participants [70]. In miso and tempeh, the aglycone form is the most abundant one [9]. In some Asian countries, isoflavone intake, usually derived from soy consumption, can be associated with a lower prevalence of cardiovascular diseases (CVDs). Isoflavone content in soy-derived products is usually lower than in soybeans [17]. Murota K., Nakamura Y., Uehara M. Flavonoid metabolism: The interaction of metabolites and gut microbiota. Soy isoflavones osteoprotective role in postmenopausal women: Mechanism of action. 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. Collison M.W. Vlachopoulos C., Aznaouridis K., Stefanadis C. Prediction of cardiovascular events and all-cause mortality with arterial stiffness: A systematic review and meta-analysis. Finally, isoflavones could be useful in reducing hot flushes associated with menopause. Nachvak S.M., Moradi S., Anjom-Shoae J., Rahmani J., Nasiri M., Maleki V., Sadeghi O. 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. Diversely, Liu et al. 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]. 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. 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. Moreover, a higher intake of soy isoflavones was associated with a lower risk of mortality from gastric, colorectal, and lung cancers. 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). Sex and long-term soy diets affect the metabolism and excretion of soy isoflavones in humans. (2016) also studied whether there was an association between different types of interventions and the reduction in hot flushes and night sweats [90]. You et al. Menopause is characterized by a decrease in estrogen levels and is often accompanied by a range of symptoms. Hairi H.A., Shuid A.N., Ibrahim N., Jamal J.A., Mohamed N., Mohamed I.N. 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 this section, 16 meta-analyses have been revised: Nachvack et al. 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. 8600 Rockville Pike Received 2020 Nov 30; Accepted 2020 Dec 15. Phenolic compounds, characterized by the presence of a hydroxyl group attached to at least one aromatic ring, can be classified as flavonoids and non-flavonoids. Most peculiar is that moonlight exposure causes a rise in blood pressure. Watanabe S., Yamaguchi M., Sobue T., Takahashi T., Miura T., Arai Y., Mazur W., Whl K., Adlercreutz H. Pharmacokinetics of soybean isoflavones in plasma, urine and feces of men after ingestion of 60 g baked soybean powder (kinako). Isoflavone glycosides have to be hydrolyzed to the aglycone form prior to its absorption by passive diffusion in the upper small intestine [28]. In Japanese men, pre-diagnostic circulating levels of genistein, daidzein and equol did not significantly affect prostate cancer risk. In general, evidence regarding the use of isoflavones on vasomotor symptoms suggests that they could be useful in reducing hot flushes. Effect of soy isoflavone supplementation on plasma lipoprotein(a) concentrations: A meta-analysis. Association between Dietary Isoflavones in Soy and Legumes and Endometrial Cancer: A Systematic Review and Meta-Analysis. 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 conclusion was that isoflavones exerted little influence over bone mineral density and thus over bone health during menopause, although not all the studies observed the same effect. Setchell K.D., Brown N.M., Lydeking-Olsen E. The clinical importance of the metabolite equol-a clue to the effectiveness of soy and its isoflavones. (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]. Anywise, it has been observed that both isoflavones are demethylated by microbiota, formononetin to daidzein and biochanin A to genistein. This is mainly due to their potential adverse effects, which range from increased coronary heart disease to stroke and cancer [53,85]. 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. However, in the meta-analysis, a minor enhancement in flow-mediated dilation after soy protein supplementation was found. Efficacy of phytoestrogens for menopausal symptoms: A meta-analysis and systematic review. Prez-Cornago et al. With regard to the geographical area, the authors suggested a significant protective effect of isoflavone intake in Asian populations, which have a higher consumption of isoflavones than Western populations. On the contrary, a systematic review and meta-analysis reported by Man et al. 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]. 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.

Dietary phytoestrogens and biomarkers of their intake in relation to cancer survival and recurrence: A comprehensive systematic review with meta-analysis. The mean age of women ranged from 49 to 58.3 and 48 to 60.1 years in the placebo and phytoestrogen groups, respectively, and women were followed up for a period of 3 to 12 months. 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. Sotoca A.M., van den Berg H., Vervoort J., van der Saag P., Strm A., Gustafsson J.A., Rietjens I., Murk A.J. The authors observed that soy isoflavone consumption was inversely associated with cancer deaths. In general terms, caution should be exercised with the use of high doses of isoflavones in women with a family history of breast cancer [49]. Proof by rational experiment seems to have been. Contraction stimulates translocation of glucose transporter GLUT4 in skeletal muscle through a mechanism distinct from that of insulin. 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. That's what behavioral ecologist Jenny York learned while studying white-browed sparrow weavers . Qiu S., Jiang C. Soy and isoflavones consumption and breast cancer survival and recurrence: A systematic review and meta-analysis. They also note that the effects of isoflavones are greater when administered as aglycones. Karr S.C., Lampe J.W., Hutchins A.M., Slavin J.L. (These include stress, nervous exhaustion, insomnia, anxiety, neuralgias and spastic pain, moderate depression, dementias and cognitive deficits in the elderly, obesity, and eating disorders.) Inverse association between isoflavone consumption and colorectal cancer risk in case-control studies, but not in cohort studies. Rienks J., Barbaresko J., Nthlings U. For the development of this section, the meta-analyses and systematic reviews published between 2015 and 2020 were taken into account. 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]. (2018), 30 articles were included for analysis; 15 of them were case-control studies, eight cohort studies and seven nested case-control studies [76]. As in the previous study, the onset of soy isoflavones was very slow in comparison with other non-hormonal treatments. Thirty-seven articles presenting evidence of the physiological effects of viewing nature were selected. Effects of isoflavones in bone health maintenance.

Soy isoflavone consumption and colorectal cancer risk: A systematic review and meta-analysis. In the meta-analysis reported by Chen et al. In conclusion, this study reported some evidence that suggests the beneficial role that daidzein and genistein play in preventing breast cancer risk. Li L., Lv Y., Xu L., Zheng Q. Quantitative efficacy of soy isoflavones on menopausal hot flashes. Discover world-changing science. Batterham T.J., Shutt D.A., Braden A.W.H., Tweeddale H.J. ; Funding Acquisition, M.P.P. In this sense, Micek et al. Looking at a few examples of moonlight's. 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]. 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. Lastly, with regard to isoflavone consumption safety, it seems that they are safe and that the most common adverse effect is mild and occurs at the gastrointestinal level. Kelly G.E., Nelson C., Waring M.A., Joannou G.E., Reeder A.Y. Oral isoflavone supplementation on endometrial thickness: A meta-analysis of randomized placebo-controlled trials.

Possible mechanism of action of isoflavones for cancer prevention. (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]. So long ago as 1880 Siemens showed that continuous exposure to arc lamps promoted luxuriance of foliage . van der Schouw Y.T., Kreijkamp-Kaspers S., Peeters P.H., Keinan-Boker L., Rimm E.B., Grobbee D.E. For this reason, the results should be interpreted with caution, and more randomized clinical trials are required. Of those, 35 have 4 / 3, which can be demonstrated by having a computer generate the 3375 combinations and count those that satisfy the criterion.Therefore, by chance alone, one would expect 35/3375 or about 1/96 studies to exhibit as good a coincidence with the full moon as that observed by the authors. Scientists often disagree about certain things. Postprandial lipemia detects the effect of soy protein on cardiovascular disease risk compared with the fasting lipid profile. 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). However, all the authors agree that further studies are necessary so as to confirm these results. 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. 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]. In their systematic revision, which included 1307 menopausal (n = 139) and post-menopausal (n = 1268) women, Perna et al. 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. , probably related to their potential adverse effects in the meta-analysis included 15 studies in the.
