Moonlight sonata. 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]. The site is secure. Nevertheless, this association was not shown when equol or isoflavones were consumed. Isoflavones Biosynthesis, Occurence and Health Effects. As with other phenolic compounds, isoflavones can be presented as free forms (aglycones) or conjugated with carbohydrates (glycosides). Acid rain also removes minerals and nutrients from the soil that trees need to grow. 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]. Finally, isoflavones could be useful in reducing hot flushes associated with menopause. Efficacy of phytoestrogens for menopausal symptoms: A meta-analysis and systematic review. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (, isoflavones, flavonoids, phytoestrogens, soy, bone health, cardiovascular risk, cancer, menopausal symptoms. The authors observed that soy isoflavone consumption was inversely associated with cancer deaths. For this reason, the results should be interpreted with caution, and more randomized clinical trials are required. (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]. Gruber C.J., Tschugguel W., Schneeberger C., Huber J.C. Production and actions of estrogens. The authors studied all possible correlations between isoflavone consumption and the risk of breast cancer. Prospective study on usual dietary phytoestrogen intake and cardiovascular disease risk in Western women. van Erp-Baart M.A., Brants H.A., Kiely M., Mulligan A., Turrini A., Sermoneta C., Kilkkinen A., Valsta L.M. Lu L.J., Anderson K.E. It follows that additional high-quality, large-scale randomized controlled trials are needed. Moreover, a higher intake of soy isoflavones was associated with a lower risk of mortality from gastric, colorectal, and lung cancers. Due to a decline in sunlight, the development of leaves . However, the authors pointed out several limitations of this study, such as the important source of heterogeneity in their study. Bustamante-Rangel M., Delgado-Zamarreo M.M., Perez-Martin L., Rodriguez-Gonzalo E., Dominguez-Alvarez J. They observed that daidzein and genistein intakes were associated with a significant reduction of prostate cancer risk. The main isoflavones found in foodstuffs are daidzein, genistein and glycitein, as well as biochanin A and formononetin [9,12]. A systematic review and meta-analysis of the effects of isoflavone formulations against estrogen-deficient bone resorption in peri- and postmenopausal women. Jiang R., Botma A., Rudolph A., Hsing A., Chang-Claude J. Phyto-oestrogens and colorectal cancer risk: A systematic review and dose-response meta-analysis of observational studies. In fact, all the body fluids, as the tides, were controlled by the lunar phases. 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. Modified from Mace et al. Sulfation of the isoflavones genistein and daidzein in human and rat liver and gastrointestinal tract. Concerning this issue, six meta-analyses and two systematic reviews are included in the present review (Table 5). 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. Plants grow best when the moon is in the waxing phase, when its gravitational pull is strongest. Treutter D. Significance of flavonoids in plant resistance and enhancement of their biosynthesis. Messina M.J. Legumes and soybeans: Overview of their nutritional profiles and health effects. Potential health adverse effects in the intake of isoflavones have been postulated due to their estrogenic activity, especially in relation to breast cancer. 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. Yu Y., Jing X., Li H., Zhao X., Wang D. Soy isoflavone consumption and colorectal cancer risk: A systematic review and meta-analysis. (2019) studied whether equol supplementation could benefit equol nonproducer subjects in lowering the incidence and severity of hot flushes [85]. 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. Before 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. Conceptualization, S.G.-Z. However, a limitation in this field is that there is still a great heterogeneity among studies. (2017) included 26 trials with 2652 participants [48]. 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]. Zhong X.S., Ge J., Chen S.W., Xiong Y.Q., Ma S.J., Chen Q. In conclusion, this study reported some evidence that suggests the beneficial role that daidzein and genistein play in preventing breast cancer risk. 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]. In any case, it is important to bear in mind that a great number of expert scientists and doctors think that breast cancer survivors should not increase their isoflavone intake [94], although others consider that their consumption is safe and beneficial [95]. 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. Determination of total soy isoflavones in dietary supplements, supplement ingredients, and soy foods by high-performance liquid chromatography with ultraviolet detection: Collaborative study. (2016) suggested that a daily intake of soy isoflavones, ranging from 20 to 100 mg/day, reduced total cholesterol and triglyceride plasma concentrations, as well as some markers of oxidative stress (nitric oxide and malonaldehyde), thus reducing cardiovascular risk [52]. Franco O.H., Chowdhury R., Troup J., Voortman T., Kunutsor S., Kavousi M., Oliver-Williams C., Muka T. Use of Plant-Based Therapies and Menopausal Symptoms: A Systematic Review and Meta-analysis. It is also important to mention that isoflavones could act as potential anticancer compounds due to their antioxidant role in malignant cell proliferation and differentiation (Figure 5). In Japanese men, pre-diagnostic circulating levels of genistein, daidzein and equol did not significantly affect prostate cancer risk. For this reason, the results should be interpreted with caution, and more randomized clinical trials are required. It is well-known that some of the most accurate BP readings occur right as someone wakes up and at that event, the BP will be shown for the most part to stay lower than that of a daily average. Atkinson C., Frankenfeld C.L., Lampe J.W. (2018) analyzed 12 studies with 37,275 women with breast cancer and reported that soy isoflavone consumption at a pre-diagnosis stage might have a small effect on the survival of postmenopausal women with breast cancer [69]. 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]. Estimated Asian adult soy protein and isoflavone intakes. The intensity of moonlight at different times during the month can also affect the development of plants. The association between dietary isoflavones intake and gastric cancer risk: A meta-analysis of epidemiological studies. 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). 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. Interestingly, soy protein isolate (void of isoflavones through alcoholic extraction during the protein solation phase) did not show these effects. 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]. 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. 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]. Thirty-seven articles presenting evidence of the physiological effects of viewing nature were selected. While a moderate intake of soy isoflavones did not significantly affect breast cancer risk, a significant reduction was shown when the intake was high. 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. 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. ), 2CIBEROBN Physiopathology of Obesity and Nutrition, Institute of Health Carlos III, 01006 Vitoria, Spain, 3Bioaraba Health Research Institute, 01002 Vitoria, Spain. 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. The difference for isoflavones required to find an effect can be due to variations in the amount of isoflavone intake between both populations. Metabolites of dietary (soya) isoflavones in human urine. This is mainly due to their potential adverse effects, which range from increased coronary heart disease to stroke and cancer [53,85]. sharing sensitive information, make sure youre on a federal van der Schouw Y.T., Kreijkamp-Kaspers S., Peeters P.H., Keinan-Boker L., Rimm E.B., Grobbee D.E. This chemical feature confers estrogenic or antiestrogenic effects to isoflavones, depending on the cell type and the binding to - or -estrogen receptors. In the same line, Yu et al. Abstract BELIEFS that phases of the moon have a differential effect on the rate of development of plants are both ancient and world-wide. Kelly G.E., Nelson C., Waring M.A., Joannou G.E., Reeder A.Y. 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]. For the development of this section, the meta-analyses and systematic reviews published between 2015 and 2020 were taken into account. [12,42]. Moreover, the authors suggested that ethnicity could have had influenced this association, but studies with larger sample sizes are needed to confirm this hypothesis. Franco et al. In this study, five prospective cohort studies and seven case-control studies, with 6275 cases and 393,776 controls, were included. Although smaller in quantity, isoflavones are also present in chickpeas, nuts, fruits and vegetables [11]. 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. Adlercreutz H., Markkanen H., Watanabe S. Plasma concentrations of phyto-oestrogens in Japanese men. The authors found a significant inverse association between isoflavone intake and both overall mortality and breast cancer recurrence. Despite the positive effect of isoflavones, the authors emphasized that the effects took a long time to appear. Ten studies reported a significant reduction in hot flush frequency in the phytoestrogen group when compared with the placebo group. Isoflavones are phenolic compounds with a chemical structure similar to that of estradiol. That aluminum may be harmful to plants as well as animals. In addition, Qiu et al. Further, Chalvon-Demersay et al.

Regarding endometrial cancer, three prospective and five case-control studies were analyzed, which suggested a lower endometrial cancer risk associated with isoflavone consumption. Implications of phytoestrogen intake for breast cancer. 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). The improvement was greater in treatments lasting more than one year and in subjects with normal weight, probably because subjects with excessive body weight have a lesser risk of bone loss. 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.

Moreover, the number of publications grouping women according to pre- or post-diagnosis intake criteria is small. "It's not. Lastly, Zhang et al. The authors found a statistical inverse association between isoflavone consumption and colorectal cancer risk in case-control studies, although not in cohort studies. 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. Zaheer K., Humayoun Akhtar M. An updated review of dietary isoflavones: Nutrition, processing, bioavailability and impacts on human health. 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]. 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. Thus, soybean can be considered as the best food source. Beneficial role of dietary phytoestrogens in obesity and diabetes. Li L., Xu L., Wu J., Dong L., Zhao S., Zheng Q. The .gov means its official. ; WritingOriginal Draft Preparation, S.G.-Z., M.G.-A., A.F.-Q., I.E. Indeed, the dose levels of dietary isoflavones require a better definition, and the measurements of isoflavone consumption should be provided in quantifiable terms. 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. . Therefore, it is necessary to support these results with additional studies. 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]. 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. and J.T. However, in the meta-analysis, a minor enhancement in flow-mediated dilation after soy protein supplementation was found. Future research in this field should quantify isoflavones as accurately as possible, analyzing larger cohorts and lengthening the follow-up stage. The increased moonlight enhances leaf growth during the new moon and second quarter. Isoflavone glycosides have to be hydrolyzed to the aglycone form prior to its absorption by passive diffusion in the upper small intestine [28]. 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. Hence, plants grow faster and healthier. (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]. Knowledge awaits. Bhathena S.J., Velasquez M.T. Thus, its consumption, according to epidemiological and clinical studies, has been postulated to be related to a decrease in the risk of different diseases. In contrast, red clover was not associated with changes in the hot flush frequency. Federal government websites often end in .gov or .mil. Gaya P., Medina M., Snchez-Jimnez A., Landete J.M. HRT: hormone replacement therapy, RCT: randomized controlled trial, VSM: vasomotor symptoms. Similarly, Li et al. 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]. 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]. Altogether, these results show that further studies are needed in order to find stronger conclusions. Scientists not only seek supporting clues, but falsifying clues as well. Whilst soy isoflavones show positive effects when compared with placebo, synthetic, or a combination of different types of isoflavones seem to be more effective than natural soy. and Rossi et al. Comparative efficacy of nonhormonal drugs on menopausal hot flashes. However, the intake of specific isoflavones, genistein and daidzein, was indeed significantly associated with a reduced risk of this type of cancer. Influence of cellular ERalpha/ERbeta ratio on the ERalpha-agonist induced proliferation of human T47D breast cancer cells. Due to its structural similarity to the estrogen-like compound 17-estradiol (Figure 1), they are referred to as phytoestrogens. 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]. 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]. In this systematic review, 123 studies were included, with a total number of 516,330 participants. 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. Batterham T.J., Shutt D.A., Braden A.W.H., Tweeddale H.J. FOIA Daidzein is first converted into dihydrodaidzein, which is the precursor of both equol and O-demethylangolensin (O-DMA) [37]. This study was supported by Instituto de Salud Carlos III (CIBERobn) under Grant CB12/03/30007, Basque Government under Grant PA20/04 and the University of the Basque Country under Grant GIU18-173. On the contrary, a systematic review and meta-analysis reported by Man et al. This fact was not taken into account in previous meta-analyses, and thus it may justify the discrepancies amongst them. The work reported by Lambert et al. The authors indicated that no consensus was found regarding the protective effects of soy isoflavones (2080 mg) and equol (10 mg) on bone resorption. 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. With regard to prostate cancer, it has been proposed that it might be affected by isoflavone consumption due to its effect on hormone metabolism. Thus, the EFSA scientific committees opinion agreed that isoflavone intake was safe, at least in the doses that the analyzed studies have used. 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]. Daidzein, genistein and glycitein occur naturally in the aglycone form, and thus their absorption is faster than that of others. 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]. They observed that it was dose-dependent at low to moderate soybean consumption. Postprandial lipemia detects the effect of soy protein on cardiovascular disease risk compared with the fasting lipid profile. aimed to compare the effects of animal and plant-sourced proteins on lipemia . Effects of isoflavones in menopausal symptoms. Since hepatic lipase and lipoprotein lipase hydrolyze triglycerides into their constituents glycerol and fatty acids, their activation results in the delivery of the fatty acids to tissues such as muscle and adipose tissue. Tamura A., Shiomi T., Hachiya S., Shigematsu N., Hara H. Low activities of intestinal lactase suppress the early phase absorption of soy isoflavones in Japanese adults. 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. 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. 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 authors reported that isoflavone intake from soy products and legumes was associated with a 19% reduction in endometrial cancer risk. Isoflavone content in soy-derived products is usually lower than in soybeans [17]. Dead or dying trees are a common sight in areas effected by acid rain. Morning 3: Temp 98.6 BP 124/83 Pulse 62 bpm. Dietary isoflavones or isoflavone-rich food intake and breast cancer risk: A meta-analysis of prospective cohort studies. 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]. government site. In this sense, Micek et al. (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]. 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. Intestinal transport of quercetin glycosides in rats involves both deglycosylation and interaction with the hexose transport pathway. 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. Soy isoflavones osteoprotective role in postmenopausal women: Mechanism of action. 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. In the systematic review reported by Perna et al. The effect of soy isoflavones on arterial stiffness: A systematic review and meta-analysis of randomized controlled trials. That's what behavioral ecologist Jenny York learned while studying white-browed sparrow weavers . Isoflavones (high dose: 0.675.5 mg/day; and low dose: 0.0120.1 mg/day). 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. 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. Thanks for reading Scientific American. This difference could explain the slow effect of isoflavones in alleviating hot flushes. 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. Some epidemiological studies indicate that the incidence of some types of cancer is lower in eastern countries than in western ones. In this section, 16 meta-analyses have been revised: Nachvack et al. (2018), 30 articles were included for analysis; 15 of them were case-control studies, eight cohort studies and seven nested case-control studies [76]. (2016) also studied whether there was an association between different types of interventions and the reduction in hot flushes and night sweats [90]. 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]. 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]. 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.
