In addition, it is important to highlight that interindividual differences in gut bacterial populations are responsible for the diverse effects of isoflavones in humans. An official website of the United States government. Estimated Asian adult soy protein and isoflavone intakes. Ingram D., Sanders K., Kolybaba M., Lopez D. Case-control study of phyto-oestrogens and breast cancer. This is mainly due to their potential adverse effects, which range from increased coronary heart disease to stroke and cancer [53,85]. On the contrary, women who were already equol producers did not obtain any additional benefit from supplements of equol or isoflavones. Potential health adverse effects in the intake of isoflavones have been postulated due to their estrogenic activity, especially in relation to breast cancer. (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]. 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. Lastly, Abshirini et al. Yu Y., Jing X., Li H., Zhao X., Wang D. Soy isoflavone consumption and colorectal cancer risk: A systematic review and meta-analysis. In addition, Qiu et al. Is equol production beneficial to health? 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. Metabolism of intraruminally administered [4-. As with other phenolic compounds, isoflavones can be presented as free forms (aglycones) or conjugated with carbohydrates (glycosides). Moreover, Rienks et al. Sansai et al. (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]. Soy isoflavones and their metabolites modulate cytokine-induced natural killer cell function. Thus, its consumption, according to epidemiological and clinical studies, has been postulated to be related to a decrease in the risk of different diseases. Indeed, some authors speculate that hepatic and lipoprotein lipase activity may have been altered after variable isoflavone intake from soybean, although no experimental data were provided [67]. (2017) also analyzed eight studies of prostate cancer, and they found an association between isoflavone intake and prostate cancer risk [61]. 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). 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. 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. 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]. U.S. Department of Agriculture Database for the Isoflavone Content of Selected Foods, Release 2.0. Acid rain also removes minerals and nutrients from the soil that trees need to grow. 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. 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). 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. Moreover, a higher intake of soy isoflavones was associated with a lower risk of mortality from gastric, colorectal, and lung cancers. 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. Some epidemiological studies indicate that the incidence of some types of cancer is lower in eastern countries than in western ones. 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]. The majority of the studies that used display stimuli, such as photos, 3D images, virtual reality, and videos of natural landscapes, confirmed that viewing natural scenery led to more relaxed body responses than viewing the control. The authors declare no conflict of interest. However, there is still a great heterogeneity among studies, which makes the current data inconclusive. 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).

In their systematic revision, which included 1307 menopausal (n = 139) and post-menopausal (n = 1268) women, Perna et al. 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. 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. Possible mechanism of action of isoflavones for menopausal symptoms. The main isoflavones found in foodstuffs are daidzein, genistein and glycitein, as well as biochanin A and formononetin [9,12]. 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. Licensee MDPI, Basel, Switzerland. [12,42]. Franco et al. Isoflavone glycosides have to be hydrolyzed to the aglycone form prior to its absorption by passive diffusion in the upper small intestine [28]. 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 the systematic review reported by Perna et al. 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). On the contrary, a systematic review and meta-analysis reported by Man et al. Lambert M.N.T., Hu L.M., Jeppesen P.B. They found that the use of dietary isoflavones or supplements and extracts was associated with an improvement in hot flushes, but not with a reduction in the frequency of night sweats. 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]. Jun S., Shin S., Joung H. Estimation of dietary flavonoid intake and major food sources of Korean adults. Soy products (0.05130 g/day) and total isoflavones (0.28 to 63 mg/day). 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. 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]. Isoflavone intake in four different European countries: The VENUS approach. In like manner, a meta-analysis by Simental-Menda et al. Menopause is characterized by a decrease in estrogen levels and is often accompanied by a range of symptoms. Applegate C.C., Rowles J.L., Ranard K.M., Jeon S., Erdman J.W. Grosso G., Godos J., Lamuela-Raventos R., Ray S., Micek A., Pajak A., Sciacca S., DOrazio N., Del Rio D., Galvano F. A comprehensive meta-analysis on dietary flavonoid and lignan intake and cancer risk: Level of evidence and limitations. In some Asian countries, isoflavone intake, usually derived from soy consumption, can be associated with a lower prevalence of cardiovascular diseases (CVDs). ; WritingOriginal Draft Preparation, S.G.-Z., M.G.-A., A.F.-Q., I.E. (2016) also studied whether there was an association between different types of interventions and the reduction in hot flushes and night sweats [90]. 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. Bethesda, MD 20894, Web Policies 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). Bacterial metabolites of isoflavones forming in the gut. The most significant food source of isoflavones in humans is soy-derived products. The enzymes responsible for the hydrolysis of isoflavone glycosides are glucosidases, which can be produced by the intestinal mucosa or the microbiota [29]. 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. Postprandial lipemia detects the effect of soy protein on cardiovascular disease risk compared with the fasting lipid profile. Soy Consumption and the Risk of Prostate Cancer: An Updated Systematic Review and Meta-Analysis. The results indicated that the isoflavone intake decreased the ovarian cancer risk by 33%. In this systematic review, 123 studies were included, with a total number of 516,330 participants. Although smaller in quantity, isoflavones are also present in chickpeas, nuts, fruits and vegetables [11]. Although results vary greatly, most of these applications are supported by at least a few clinical studies. 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. 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. The authors indicated that high concentrations of daidzein and genistein (no specific values concerning these concentrations were available) were related to 34% and 28% reduction in breast cancer risk, respectively, whereas no association with equol was found. (2016) included 17 studies (nine case-control studies and eight cohort studies) [80]. 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]. Lastly, Zhang et al. Effects of Acid Rain on Plants and Trees. 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. 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. 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. With regard to the mechanisms by which isoflavones act to reduce cancer risk, it has been suggested that the effects are due to the similarity of the isoflavone molecule to estradiol. Rossi M., Amaretti A., Roncaglia R., Leonardi A., Raimondi S. Dietary isoflavones and dietary microbiota: Metabolism and transformation into bioactive compounds. Hormone replacement therapy has been proven to be effective in reducing vasomotor symptoms, although isoflavones have gained popularity as an alternative treatment to hormone replacement therapy to relieve menopausal symptoms. The authors found a statistical inverse association between isoflavone consumption and colorectal cancer risk in case-control studies, although not in cohort studies. Abdi 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. Continue reading with a Scientific American subscription. 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. Sirotkin A.V., Harrath A.H. Phytoestrogens and their effects. Man B., Cui C., Zhang X., Sugiyama D., Barinas-Mitchell E., Sekikawa A. Thus, soybean can be considered as the best food source. aimed to compare the effects of animal and plant-sourced proteins on lipemia and blood pressure [60]. Soy isoflavones osteoprotective role in postmenopausal women: Mechanism of action. Hairi H.A., Shuid A.N., Ibrahim N., Jamal J.A., Mohamed N., Mohamed I.N. 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. 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. Conceptualization, S.G.-Z. van der Schouw Y.T., Kreijkamp-Kaspers S., Peeters P.H., Keinan-Boker L., Rimm E.B., Grobbee D.E. Despite the positive effect of isoflavones, the authors emphasized that the effects took a long time to appear. 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. 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]. 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]. Potential mechanism of action of isoflavones on bone metabolism. Sulfation of the isoflavones genistein and daidzein in human and rat liver and gastrointestinal tract. Professor Piazza Smyth, the Astronomer Royal for Scotland, in his interesting account of a recent scientific expedition made by him to the Peak of Teneriffe, has set at rest the vexed question of the heat of the moonlight. The aglycone and conjugate forms of genistein represent up to 60% of total isoflavones, this being up to 30% in the case of daidzein. Anywise, it has been observed that both isoflavones are demethylated by microbiota, formononetin to daidzein and biochanin A to genistein. The authors suggested that this difference could be due to different genetic backgrounds and dietary patterns among Asian and Western populations. The association between dietary isoflavones intake and gastric cancer risk: A meta-analysis of epidemiological studies. 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. 2023 Scientific American, a Division of Springer Nature America, Inc. The work reported by Lambert et al. By contrast, it seems that soy isoflavones do not lead to a meaningful protective effect on cardiovascular risk. But that doesn't mean that they dig in their heels and argue about it. For this reason, the results should be interpreted with caution, and more randomized clinical trials are required. Daidzein is first converted into dihydrodaidzein, which is the precursor of both equol and O-demethylangolensin (O-DMA) [37]. Focusing on the overall intake of isoflavones in humans, several studies have reported varied results. [(accessed on 21 September 2020)]; Messina M., Nagata C., Wu A.H. (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]. This finding suggests that bacterial deglycosylation contributes significantly to isoflavone absorption [32]. Chen L.R., Ko N.Y., Chen K.H. 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. Bhathena S.J., Velasquez M.T. In miso and tempeh, the aglycone form is the most abundant one [9]. In the same line, Yu et al. By contrast, it seems that soy isoflavones do not lead to a meaningful protective effect on cardiovascular risk. Isoflavones have received attention due to their putative healthy properties. Abdi F., Alimoradi Z., Haqi P., Mahdizad F. Effects of phytoestrogens on bone mineral density during the menopause transition: A systematic review of randomized, controlled trials. Regarding cancer, scientific evidence suggests that isoflavones could be useful in reducing the risk of suffering some types of cancer, such as breast and endometrial cancer, but further studies are needed to confirm these results. This meta-analysis included 266,699 participants (21,612 patients with prostate cancer among them). 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]. 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. 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. 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). However, in the meta-analysis, a minor enhancement in flow-mediated dilation after soy protein supplementation was found. (2019) studied whether equol supplementation could benefit equol nonproducer subjects in lowering the incidence and severity of hot flushes [85]. 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.
