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, 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. Chadha R., Bhalla Y., Jain A., Chadha K., Karan M. Dietary Soy Isoflavone: A Mechanistic Insight. Isoflavones have received attention due to their putative healthy properties. Moreover, Rienks et al. [12,42]. Further, Chalvon-Demersay et al. Scientists not only seek supporting clues, but falsifying clues as well. The most significant food source of isoflavones in humans is soy-derived products. Isoflavone glycosides have to be hydrolyzed to the aglycone form prior to its absorption by passive diffusion in the upper small intestine [28]. (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]. Effects of Acid Rain on Plants and Trees. Sotoca A.M., van den Berg H., Vervoort J., van der Saag P., Strm A., Gustafsson J.A., Rietjens I., Murk A.J. This result has implications for granivory and perhaps plant demography in invaded and restored coastal habitats. and Rossi et al. 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. The authors observed that soy isoflavone consumption was inversely associated with cancer deaths. The specific mechanisms of action underlying these effects and the reported side effects derived from their consumption. In conclusion, this study reported some evidence that suggests the beneficial role that daidzein and genistein play in preventing breast cancer risk. The https:// ensures that you are connecting to the Nevertheless, the results do not seem entirely conclusive, as there are discrepancies among the studies included in the systematic reviews and in the meta-analyses, probably related to their experimental designs. On the contrary, women who were already equol producers did not obtain any additional benefit from supplements of equol or isoflavones. 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. 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. Rienks J., Barbaresko J., Nthlings U. 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]. 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. Only one study examined the effects of red clover on night sweats, and a significant association was found, which showed a decreased frequency in night sweats. ; Funding Acquisition, M.P.P. Further, Chalvon-Demersay et al. . Analysis of isoflavones in Foods. This meta-analysis included 266,699 participants (21,612 patients with prostate cancer among them). National Library of Medicine Bacterial metabolites of isoflavones forming in the gut. 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). 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. The authors suggested that this difference could be due to different genetic backgrounds and dietary patterns among Asian and Western populations. Isoflavone excretion occurs mainly through urine and feces, primarily in the conjugate forms, and up to 95% takes place in 24 h [43]. You J., Sun Y., Bo Y., Zhu Y., Duan D., Cui H., Lu Q. Nevertheless, this association was not shown when equol or isoflavones were consumed. Qiu S., Jiang C. Soy and isoflavones consumption and breast cancer survival and recurrence: A systematic review and meta-analysis. In some Asian countries, isoflavone intake, usually derived from soy consumption, can be associated with a lower prevalence of cardiovascular diseases (CVDs). van der Schouw Y.T., Kreijkamp-Kaspers S., Peeters P.H., Keinan-Boker L., Rimm E.B., Grobbee D.E. 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 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. Future research in this field should quantify isoflavones as accurately as possible, analyzing larger cohorts and lengthening the follow-up stage. In contrast, the effects on bone resorption biomarkers were more favorable in overweight or obese women than in women with a healthy weight. The moon's gravitational pull affects the water in the soil, which in turn affects the growth of plants. (2017) also analyzed eight studies of prostate cancer, and they found an association between isoflavone intake and prostate cancer risk [61]. Daily J.W., Ko B.S., Ryuk J., Liu M., Zhang W., Park S. Equol Decreases Hot Flashes in Postmenopausal Women: A Systematic Review and Meta-Analysis of Randomized Clinical Trials. Beneficial role of dietary phytoestrogens in obesity and diabetes. ), 2CIBEROBN Physiopathology of Obesity and Nutrition, Institute of Health Carlos III, 01006 Vitoria, Spain, 3Bioaraba Health Research Institute, 01002 Vitoria, Spain. They observed that it was dose-dependent at low to moderate soybean consumption. . Morning 3: Temp 98.6 BP 124/83 Pulse 62 bpm. Franco et al. ); sue.uhe@zelaznog.enatiam (M.G.-A. The site is secure. 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]. Considering the isoflavone chemical structure, potential health adverse effects of these compounds related to their estrogenic activity have been postulated, despite the scientific opinion offered by EFSA indicating that isoflavone intake was safe. For this purpose, 23 studies with 2167 patients were included in this meta-analysis, which showed that a daily dose of more than 54 mg could decrease the endometrial thickness in North American women, whereas the contrary effect was observed in the Asian sample. Endometrial cancer (Table 4), as well as breast cancer, is an estrogen-dependent cancer type related to high circulating estradiol concentrations. 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.

With regard to the published meta-analysis, the studies included were restricted to randomized controlled trials. Reduction of the endometrial thickness in North American women (for 0.23 mm). Gut bacterial metabolism of the soy isoflavone daidzein: Exploring the relevance to human health. For this reason, the bioavailability of isoflavones has been extensively characterized in animal models and humans [25,26,27]. 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]. Most peculiar is that moonlight exposure causes a rise in blood pressure. (2020) carried out their meta-analysis of 63 controlled trials, including 6427 postmenopausal women and concluded that isoflavones improve bone density at the lumbar spine, femoral neck and the distal radius in menopausal women [50]. With regard to prostate cancer, it has been proposed that it might be affected by isoflavone consumption due to its effect on hormone metabolism. Sirotkin A.V., Harrath A.H. Phytoestrogens and their effects. 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]. Furthermore, among the four studies of breast cancer recurrence, three studies found that isoflavone intake decreased the risk of breast cancer recurrence, although further studies are required to confirm this finding [82]. Another meta-analysis, conducted by Zhao et al. 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. 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. (2016) analyzed the effect of oral isoflavone supplementation on endometrial thickness in pre- and post-menopausal women, which is a biomarker for the proliferative effects of estrogens associated with an increased endometrial risk [72]. Proof by rational experiment seems to have been. In this line, three meta-analyses were conducted to study isoflavone consumption and endometrial cancer risk. He et al. 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. The latter is the most common form in foodstuffs, with the exception of fermented soy products, such as miso and tempeh. Conceptualization, S.G.-Z.

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. In addition, it is important to highlight that interindividual differences in gut bacterial populations are responsible for the diverse effects of isoflavones in humans. Isoflavones are found in several vegetables, mainly in legumes (Fabaceae family) such as soy, white and red clover, alfalfa and beans [9,10]. The aim of the present review is to gather the scientific evidence existing nowadays on the main beneficial effects of isoflavones on health: bone health, cardiovascular risk, cancer and menopausal symptoms. Chemical structure of 17-estradiol. 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. (2016), nine studies addressed to menopausal women and focused on bone health were analyzed [52]. 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. Vasomotor symptoms resulting from natural menopause: A systematic review and network meta-analysis of treatment effects from the National Institute for Health and Care Excellence guideline on menopause. (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]. Zhong et al. 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. Chang H.H., Robinson A.R., Common R.H. Excretion of radioactive diadzein and equol as monosulfates and disulfates in the urine of the laying hen. Lastly, Abshirini et al. Consensus: Soy isoflavones as a first-line approach to the treatment of menopausal vasomotor complaints. It follows that additional high-quality, large-scale randomized controlled trials are needed. Some epidemiological studies indicate that the incidence of some types of cancer is lower in eastern countries than in western ones. The effect of soy isoflavones on arterial stiffness: A systematic review and meta-analysis of randomized controlled trials. (2015), the authors examined the efficacy of phytoestrogens in reducing hot flushes [86]. Yu Y., Jing X., Li H., Zhao X., Wang D. Soy isoflavone consumption and colorectal cancer risk: A systematic review and meta-analysis. and transmitted securely. This difference could explain the slow effect of isoflavones in alleviating hot flushes. Sex and long-term soy diets affect the metabolism and excretion of soy isoflavones in humans. These positive effects were associated with 54 mg/day of genistein and 600 mg/day of synthetic isoflavone ipriflavone. Messina M.J. Legumes and soybeans: Overview of their nutritional profiles and health effects. Batterham T.J., Shutt D.A., Braden A.W.H., Tweeddale H.J. ; Project Administration, M.P.P. 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). Plants grow best when the moon is in the waxing phase, when its gravitational pull is strongest. Collison M.W. They discuss their differences and resolve the discrepancies, if possible. 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. Looking at a few examples of moonlight's. (2015) concluded that soy isoflavones have both a slight and slow effect in attenuating menopausal hot flushes [87]. By contrast, the total isoflavone amount is high in soy flour, protein isolate or edamame [19]. Licensee MDPI, Basel, Switzerland.

Thanks for reading Scientific American. Kurzer M.S., Xu X. Dietary phytoestrogens. Moreover, this association was more prominent among postmenopausal women than premenopausal women. and J.T. That's what behavioral ecologist Jenny York learned while studying white-browed sparrow weavers . Effects of isoflavones in different cancer types. Sulfation of the isoflavones genistein and daidzein in human and rat liver and gastrointestinal tract. The authors found a significant inverse association between isoflavone intake and both overall mortality and breast cancer recurrence. Effects of isoflavones in bone health maintenance. Daidzein is first converted into dihydrodaidzein, which is the precursor of both equol and O-demethylangolensin (O-DMA) [37]. Neuroprotective effects of 17beta-estradiol and nonfeminizing estrogens against H. Endoh H., Sasaki H., Maruyama K., Takeyama K., Waga I., Shimizu T., Kato S., Kawashima H.

Study duration ranged from four weeks to two years, with a median of 12 weeks. 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. The authors concluded that evidence for the role of isoflavones and soy products in the prevention of cardiovascular diseases was scarce and inconclusive. Due to the high prevalence of colorectal cancer, three meta-analyses addressing this issue are included in the present review. A significant 19% reduction of the risk was found at high concentrations of daidzein, but not at genistein or equol concentrations. Thus, whereas Asian populations have an average isoflavone consumption of >30 mg/day, Western populations consume <1 mg/day [83]. THE effect of light on plant life has been the subject of many scientific investigations. Intestinal transport of quercetin glycosides in rats involves both deglycosylation and interaction with the hexose transport pathway. Soy isoflavones consumption and risk of breast cancer incidence or recurrence: A meta-analysis of prospective studies. (2018), 30 articles were included for analysis; 15 of them were case-control studies, eight cohort studies and seven nested case-control studies [76]. The Sun ruled our heart, blood circulation and spine, while the Moon had influence on growth, fertility, breasts, stomach, uterus and menstrual flow. 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. (2016) conducted a meta-analysis of 18 studies involving 16,917 colorectal cancer cases in 559,486 participants [78]. 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. 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. Ronis M.J., Little J.M., Barone G.W., Chen G., Radominska-Pandya A., Badger T.M. In the end, isoflavones could be useful in reducing hot flushes associated with menopause. 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. 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. Gruber C.J., Tschugguel W., Schneeberger C., Huber J.C. Production and actions of estrogens. 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. Lu L.J., Anderson K.E. By contrast, it seems that soy isoflavones do not lead to a meaningful protective effect on cardiovascular risk. Estimated Asian adult soy protein and isoflavone intakes. and J.T. In the meta-analysis reported by Chen et al. Potential mechanism of action of isoflavones on bone metabolism. As it has been stated in the Bioavailability section, microbiota composition in humans makes equol production very variable, which yields high interindividual differences. 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. Zhang Q., Feng H., Qluwakemi B., Wang J., Yao S., Cheng G., Xu H., Qiu H., Zhu L., Yuan M. Phytoestrogens and risk of prostate cancer: An updated meta-analysis of epidemiologic studies. 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. (2016) included 17 studies (nine case-control studies and eight cohort studies) [80]. In like manner, a meta-analysis by Simental-Menda et al. Liu J., Yuan F., Gao J., Shan B., Ren Y., Wang H., Gao Y. But that doesn't mean that they dig in their heels and argue about it. Zhong X.S., Ge J., Chen S.W., Xiong Y.Q., Ma S.J., Chen Q. (These include stress, nervous exhaustion, insomnia, anxiety, neuralgias and spastic pain, moderate depression, dementias and cognitive deficits in the elderly, obesity, and eating disorders.) Finally, it is important to mention that despite the fact that potential isoflavone adverse effects have been widely studied, little is known about the side effect of the bacterial metabolite equol. Possible mechanism of action of isoflavones for cancer prevention. Micek A., Godos J., Brzostek T., Gniadek A., Favari C., Mena P., Libra M., Del Rio D., Galvano F., Grosso G. Dietary phytoestrogens and biomarkers of their intake in relation to cancer survival and recurrence: A comprehensive systematic review with meta-analysis. (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]. 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. The enzymes responsible for the hydrolysis of isoflavone glycosides are glucosidases, which can be produced by the intestinal mucosa or the microbiota [29]. 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. Applegate C.C., Rowles J.L., Ranard K.M., Jeon S., Erdman J.W. As in the previous study, the onset of soy isoflavones was very slow in comparison with other non-hormonal treatments. 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. 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. sharing sensitive information, make sure youre on a federal 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. Produced metabolites appear in plasma at variable concentrations and can enter enterohepatic circulation [28]. Apparently, soy isoflavones modified adhesion molecules by binding to vascular endothelium and mimicking the effect of a modulator of estrogen receptors [64]. Zhao T.T., Jin F., Li J.G., Xu Y.Y., Dong H.T., Liu Q., Xing P., Zhu G.L., Xu H., Miao Z.F. Effect of soy isoflavone supplementation on plasma lipoprotein(a) concentrations: A meta-analysis. Scientists often disagree about certain things. This chemical feature confers estrogenic or antiestrogenic effects to isoflavones, depending on the cell type and the binding to - or -estrogen receptors. The authors suggested that further studies grouping subjects by isoflavone intake or by the circulating isoflavone levels might enhance this association. 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). 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. (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]. It is important to point out that the spine has a high proportion of trabecular bone and that this is probably the reason why the spine is thought to be more sensitive to isoflavones. Juglans regia L. is a traditional plant that has been integrated into traditional medicine since ancient times. "It's not. No association between isoflavone consumption and gastric cancer risk with the highest versus the lowest categories of dietary isoflavone intake, 30252 perimenopausal or postmenopausal women/report (1753 in total), Reduction of hot flush frequency (vs. placebo), Slight and slow attenuation of hot flushes (vs. estradiol), Slight and slow attenuation of hot flushes (vs. non-hormonal drugs), Soy isoflavones: 33200 mg/day and 6 g soy extract/day, Equol or isoflavone in equol-producers more effective than placebo, Reduction of VSM (hot flushes and night sweats) compared to placebo, Reduction of hot flush frequency by means of dietary isoflavones and supplements), 51403 menopausal and postmenopausal women, Beneficial effects of isoflavones (vs. placebo), 40403 menopausal and postmenopausal women.
