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. Soy isoflavones and their metabolites modulate cytokine-induced natural killer cell function. Lund S., Holman G.D., Schmitz O., Pedersen O. In addition, it is important to highlight that interindividual differences in gut bacterial populations are responsible for the diverse effects of isoflavones in humans. Bardin A., Boulle N., Lazennec G., Vignon F., Pujol P. Loss of ERbeta expression as a common step in estrogen-dependent tumor progression. Lastly, the association between dietary isoflavone intake and the risk of developing gastric cancer has also been analyzed. (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]. Franco et al. Create your free account or Sign in to continue. In the meta-analysis reported by Applegate et al. Duffy C., Perez K., Partridge A. 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]. For this reason, the results should be interpreted with caution, and more randomized clinical trials are imperative. 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]. (2019) studied whether equol supplementation could benefit equol nonproducer subjects in lowering the incidence and severity of hot flushes [85]. 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]. But that doesn't mean that they dig in their heels and argue about it. Due to the presence of biologically active compounds, walnut was used in the . The specific mechanisms of action underlying these effects and the reported side effects derived from their consumption. (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]. Matulka R.A., Matsuura I., Uesugi T., Ueno T., Burdock G. Developmental and Reproductive Effects of SE5-OH: An Equol-Rich Soy-Based Ingredient. Plants grow best when the moon is in the waxing phase, when its gravitational pull is strongest. They are present in several vegetables, mainly in legumes such as soy, white and red clover, alfalfa and beans. (2016) published another systematic review of 23 randomized controlled trials to determine the effect of soy isoflavone extracts on bone mineral density in postmenopausal women [51]. In addition, genistein and glycitein are transformed into dihydrogenistein and dihydroglycitein, respectively, before being further converted into other metabolites. Effect of soy isoflavone supplementation on plasma lipoprotein(a) concentrations: A meta-analysis. On the contrary, a systematic review and meta-analysis reported by Man et al. van Erp-Baart M.A., Brants H.A., Kiely M., Mulligan A., Turrini A., Sermoneta C., Kilkkinen A., Valsta L.M.

Ronis M.J., Little J.M., Barone G.W., Chen G., Radominska-Pandya A., Badger T.M. Is equol production beneficial to health? HRT: hormone replacement therapy, RCT: randomized controlled trial, VSM: vasomotor symptoms. Thus, the EFSA scientific committees opinion agreed that isoflavone intake was safe, at least in the doses that the analyzed studies have used. They observed that daidzein and genistein intakes were associated with a significant reduction of prostate cancer risk. 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. This difference could explain the slow effect of isoflavones in alleviating hot flushes. Magee P.J. Association between Dietary Isoflavones in Soy and Legumes and Endometrial Cancer: A Systematic Review and Meta-Analysis. Implications of phytoestrogen intake for breast cancer. Yan Z., Zhang X., Li C., Jiao S., Dong W. Association between consumption of soy and risk of cardiovascular disease: A meta-analysis of observational studies. (2017) also analyzed eight studies of prostate cancer, and they found an association between isoflavone intake and prostate cancer risk [61]. Moreover, five studies reported side-effect data, and after the analysis, no significant differences were observed between the two groups. In contrast, red clover was not associated with changes in the hot flush frequency. 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. Importantly, the soy variety, environmental conditions of the culture and the processing of soybeans notably influence their isoflavone content [18]. 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]. Interestingly, in a study conducted by Tamura et al., the authors observed that in individuals without the LPH enzyme, the concentration of isoflavones and derived metabolites was similar to that found in individuals without an enzyme deficiency. Soy isoflavones consumption and risk of breast cancer incidence or recurrence: A meta-analysis of prospective studies. The dose of isoflavones ranged from 30 to 200 mg/day. In the aforementioned mechanism, it has been reported that isoflavones bind to both ER and ER, although they present a higher affinity towards ER receptors [7]. However, the magnitude of risk reduction in Asian women was slightly larger than in non-Asian women (22% vs. 18%). 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). The results showed that a higher regular intake of foods rich in isoflavones might potentially decrease colorectal cancer incidence. Equol is produced from the isoflavone daidzein by intestinal bacteria, mainly in the large intestine. Federal government websites often end in .gov or .mil. Global climate change is not a future problem. The authors observed that soy isoflavone consumption was inversely associated with cancer deaths. Moreover, a higher intake of soy isoflavones was associated with a lower risk of mortality from gastric, colorectal, and lung cancers. 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]. The authors found a significant inverse association between isoflavone intake and both overall mortality and breast cancer recurrence. 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. 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. 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. 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. Continue reading with a Scientific American subscription. Apparently, soy isoflavones modified adhesion molecules by binding to vascular endothelium and mimicking the effect of a modulator of estrogen receptors [64]. However, more studies are required to provide stronger evidence. Produced metabolites appear in plasma at variable concentrations and can enter enterohepatic circulation [28]. This chemical feature confers estrogenic or antiestrogenic effects to isoflavones, depending on the cell type and the binding to - or -estrogen receptors. The main forms of conjugates in soybeans are the malonyl derivatives [14]. Finally, isoflavones could be useful in reducing hot flushes associated with menopause. Possible mechanism of action of isoflavones for cancer prevention. 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. (2015) concluded that soy isoflavones have both a slight and slow effect in attenuating menopausal hot flushes [87]. FOIA 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. ); sue.uhe@ollitrop.yupairam (M.P.P. Thirty-nine studies were included with a sample size of 200 women per trial, in which the intervention period ranged from two to 96 weeks (median 12 weeks). Concerning this issue, six meta-analyses and two systematic reviews are included in the present review (Table 5). Therefore, the authors concluded that the intake of dietary isoflavones paid a protective role against ovarian cancer. 2023 Scientific American, a Division of Springer Nature America, Inc. (2019) conducted a meta-analysis where 23 prospective studies with a total of 330,826 participants were included. Saloniemi H., Whl K., Nyknen-Kurki P., Kallela K., Saastamoinen I. Phytoestrogen content and estrogenic effect of legume fodder. Modified from Wang et al., 2006 [4]. 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. Two meta-analyses, which covered prospective cohort studies, showed that soy isoflavone consumption was not associated significantly with mortality linked to cardiovascular events [56,62]. 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]. Lu L.J., Anderson K.E. 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. 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. The light reflected off the moon has an effect on life on Earth, which isn't surprising, but not every lunar influence is heralded by a wolf's howl. In this section, 16 meta-analyses have been revised: Nachvack et al. 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]. During menopause, there is a loss of bone density that can cause osteoporosis. As it has been stated in the Bioavailability section, microbiota composition in humans makes equol production very variable, which yields high interindividual differences. Prez-Cornago et al. 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. 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]. Menopause is characterized by a decrease in estrogen levels and is often accompanied by a range of symptoms. Isoflavone intake in four different European countries: The VENUS approach. Jun S., Shin S., Joung H. Estimation of dietary flavonoid intake and major food sources of Korean adults. Some gardening folklore suggests that planting crops according to the phases of the moon will give you a better harvest, but there is little scientific evidence to back this up. National Library of Medicine sharing sensitive information, make sure youre on a federal A total of 16 studies were included in their meta-analysis with a range of 24 to 236 subjects. Atkinson C., Frankenfeld C.L., Lampe J.W. At high elevations, acidic fog and clouds might . They also explained that the differences between isoflavones and the rest of the drugs might be because the latter act by modulating central neurotransmitters and, as a consequence, by regulating the central thermoregulatory centers in the hypothalamus. "It's not. This fact was not taken into account in previous meta-analyses, and thus it may justify the discrepancies amongst them. (2016) included 17 studies (nine case-control studies and eight cohort studies) [80]. CVD: cardiovascular disease, LDL: low-density lipoprotein. ); sue.uhe@zednanref.oderfla (A.F.-Q. Chadha R., Bhalla Y., Jain A., Chadha K., Karan M. Dietary Soy Isoflavone: A Mechanistic Insight. This fact does not seem to be influenced by genetics since migrating from eastern to western countries appears to cause the loss of this protective effect. This meta-analysis included 266,699 participants (21,612 patients with prostate cancer among them). The authors indicated that no consensus was found regarding the protective effects of soy isoflavones (2080 mg) and equol (10 mg) on bone resorption. Effects of isoflavones in bone health maintenance. 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. 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. EFSA Pannel on Food Additives and Nutrient Sources Added to Food (ANS) Risk assessment for peri- and post-menopausal women taking food su pplements containing isola ted isoflavones. (2016), nine studies addressed to menopausal women and focused on bone health were analyzed [52]. Careers, Unable to load your collection due to an error. 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. While a moderate intake of soy isoflavones did not significantly affect breast cancer risk, a significant reduction was shown when the intake was high. In addition, Qiu et al. Sotoca A.M., van den Berg H., Vervoort J., van der Saag P., Strm A., Gustafsson J.A., Rietjens I., Murk A.J. (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]. In this sense, soy isoflavones have been proposed as beneficial because, in theory, they may contribute to the maintenance of good bone health (mass, mineral density and bone structure) in women who are at this stage in their life. 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]. Reduction of the endometrial thickness in North American women (for 0.23 mm). It has been described that after the oral intake of isoflavones, their peak plasma concentration in humans occurs at around seven hours [33]. They also note that the effects of isoflavones are greater when administered as aglycones. (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]. . ); sue.uhe@zelaznog.enatiam (M.G.-A. (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]. 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. Xu B., Chibber R., Ruggiero D., Kohner E., Ritter J., Ferro A., Ruggerio D. Impairment of vascular endothelial nitric oxide synthase activity by advanced glycation end products. The authors studied all possible correlations between isoflavone consumption and the risk of breast cancer. Bustamante-Rangel M., Delgado-Zamarreo M.M., Perez-Martin L., Rodriguez-Gonzalo E., Dominguez-Alvarez J. Collison M.W. For this reason, the bioavailability of isoflavones has been extensively characterized in animal models and humans [25,26,27]. Regarding cancer, scientific evidence suggests that isoflavones could be useful in reducing the risk of suffering from some types of cancer, such as breast and endometrial cancer, although further studies are needed to confirm these results. The Sun ruled our heart, blood circulation and spine, while the Moon had influence on growth, fertility, breasts, stomach, uterus and menstrual flow. Beneficial role of dietary phytoestrogens in obesity and diabetes. Juglans regia L. is a traditional plant that has been integrated into traditional medicine since ancient times. 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 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). The site is secure. 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 positive effects were associated with 54 mg/day of genistein and 600 mg/day of synthetic isoflavone ipriflavone. 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. Prospective study on usual dietary phytoestrogen intake and cardiovascular disease risk in Western women.

Liu J., Yuan F., Gao J., Shan B., Ren Y., Wang H., Gao Y. Even though red clover has a greater amount of isoflavones, it is not an edible plant, and it is consumed as a food complement. (2018), 30 articles were included for analysis; 15 of them were case-control studies, eight cohort studies and seven nested case-control studies [76]. Man B., Cui C., Zhang X., Sugiyama D., Barinas-Mitchell E., Sekikawa A. Oral isoflavone supplementation on endometrial thickness: A meta-analysis of randomized placebo-controlled trials. Bethesda, MD 20894, Web Policies 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. All authors have read and agreed to the published version of the manuscript. Rienks et al. 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. Many females sleep less and have less REM sleep. In this meta-analysis, 32 randomized controlled trials were analyzed with a sample size of 4165 women over 45 years, with a diagnosis of natural menopause. The authors concluded that evidence for the role of isoflavones and soy products in the prevention of cardiovascular diseases was scarce and inconclusive. By contrast, the total isoflavone amount is high in soy flour, protein isolate or edamame [19]. However, a limitation in this field is that there is still a great heterogeneity among studies. In the same line, in European men, isoflavone concentrations did not affect the risk of developing prostate cancer. 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. Furthermore, the dose-response analysis revealed an 8% reduction in colorectal neoplasm risk for every 20 mg/day increase in isoflavone intake in Asian populations, and for every 0.1 mg/day increase in Western populations. Hua et al. 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. The four chemical forms of the three most abundant isoflavones. Influence of cellular ERalpha/ERbeta ratio on the ERalpha-agonist induced proliferation of human T47D breast cancer cells. (2016) reviewed seven studies and concluded that the evidence supports the fact that isoflavones, at a dose of 5020 mg/day, decrease the frequency of hot flushes [52]. By contrast, it seems that soy isoflavones do not lead to a meaningful protective effect on cardiovascular risk. 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 observed that it was dose-dependent at low to moderate soybean consumption. This result has implications for granivory and perhaps plant demography in invaded and restored coastal habitats. 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. and transmitted securely.

PV panels have been linked . In some cases the purported effect may depend on external cues, such as the amount of moonlight. Further, Chalvon-Demersay et al. Rossi M., Amaretti A., Roncaglia R., Leonardi A., Raimondi S. Dietary isoflavones and dietary microbiota: Metabolism and transformation into bioactive compounds. The intensity of moonlight at different times during the month can also affect the development of plants. Murota K., Nakamura Y., Uehara M. Flavonoid metabolism: The interaction of metabolites and gut microbiota. In the same line, Yu et al. The authors declare no conflict of interest. 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. In soybeans, the three most abundant isoflavones are present in four chemical forms: aglycone, glycoside, acetylglycoside and malonylglucoside (Table 1 and Figure 2). Rienks J., Barbaresko J., Nthlings U. On the contrary, women who were already equol producers did not obtain any additional benefit from supplements of equol or isoflavones.
