Franco et al. As in the previous study, the onset of soy isoflavones was very slow in comparison with other non-hormonal treatments. This fact was not taken into account in previous meta-analyses, and thus it may justify the discrepancies amongst them. 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. 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 this sense, the authors suggested that the composition of the gut microflora may influence isoflavone absorption and metabolism and could affect the production of isoflavone metabolites, which, in turn, could mediate their biological activity. In this sense, it has been described that both isoflavones and other estrogenic molecules could mediate their beneficial effects due to two different mechanisms: the classical estrogen receptor (ER)-mediated signaling pathway and the activation of intracellular pathways such as protein tyrosine kinase, phospholipase C and mitogen-activated protein kinase (MAPK) [5,6]. The most significant food source of isoflavones in humans is soy-derived products. Hua X., Yu L., You R., Yang Y., Liao J., Chen D. Association among Dietary Flavonoids, Flavonoid Subclasses and Ovarian Cancer Risk: A Meta-Analysis. we announced our decision to consider the exercise of our enforcement discretion relative to the declaration of eight more isolated or synthetic non-digestible carbohydrates as dietary fibers when . 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 found a statistical inverse association between isoflavone consumption and colorectal cancer risk in case-control studies, although not in cohort studies. Sarri G., Pedder H., Dias S., Guo Y., Lumsden M.A. ), 2CIBEROBN Physiopathology of Obesity and Nutrition, Institute of Health Carlos III, 01006 Vitoria, Spain, 3Bioaraba Health Research Institute, 01002 Vitoria, Spain. The authors observed that soy isoflavone consumption was inversely associated with cancer deaths. The authors reported that isoflavone intake from soy products and legumes was associated with a 19% reduction in endometrial cancer risk. To address the link between lunar phases and agriculture from a scientic perspective, we conducted a review of textbooks and monographs used to teach agronomy, botany, horticulture and plant physiology; we also consider the physics that address the e ects of the Moon on our planet. 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. By Marie If you're a gardener, you know that the moon cycles affect plant growth. 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. 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 intensity of moonlight at different times during the month can also affect the development of plants. Acid rain also removes minerals and nutrients from the soil that trees need to grow. The authors concluded that evidence for the role of isoflavones and soy products in the prevention of cardiovascular diseases was scarce and inconclusive. Even though red clover has a greater amount of isoflavones, it is not an edible plant, and it is consumed as a food complement. They observed that daidzein and genistein intakes were associated with a significant reduction of prostate cancer risk. (2019), included 16 prospective cohort studies involving 11,169 breast cancer cases and 648,913 participants [70]. Collison M.W. For this reason, the bioavailability of isoflavones has been extensively characterized in animal models and humans [25,26,27]. 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. Santo A.S., Santo A.M., Browne R.W., Burton H., Leddy J.J., Horvath S.M., Horvath P.J. However, it is important to mention that this connection has been established based on pre-clinical studies, whereas data derived from clinical trials have not demonstrated such association [92]. 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. 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). In this line, three meta-analyses were conducted to study isoflavone consumption and endometrial cancer risk. 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. 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. (2016) included 17 studies (nine case-control studies and eight cohort studies) [80]. . 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. Nevertheless, it is important to consider this metabolite since it is key in the biological activity of isoflavones [13]. ; Funding Acquisition, M.P.P. 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. Ten studies reported a significant reduction in hot flush frequency in the phytoestrogen group when compared with the placebo group. Sfakianos J., Coward L., Kirk M., Barnes S. Intestinal uptake and biliary excretion of the isoflavone genistein in rats. Zhong X.S., Ge J., Chen S.W., Xiong Y.Q., Ma S.J., Chen Q. In general, evidence regarding the use of isoflavones on vasomotor symptoms suggests that they could be useful in reducing hot flushes. (2019) conducted a meta-analysis where 23 prospective studies with a total of 330,826 participants were included. In some Asian countries, isoflavone intake, usually derived from soy consumption, can be associated with a lower prevalence of cardiovascular diseases (CVDs). Nevertheless, this association was not shown when equol or isoflavones were consumed. Man B., Cui C., Zhang X., Sugiyama D., Barinas-Mitchell E., Sekikawa A. 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. 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. As with other phenolic compounds, isoflavones can be presented as free forms (aglycones) or conjugated with carbohydrates (glycosides). 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. (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]. Soy products (0.05130 g/day) and total isoflavones (0.28 to 63 mg/day). 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. Arjmandi B.H., Smith B.J. 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. Consequently, isoflavones can have estrogenic or anti-estrogenic effects [3]. 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. Hairi H.A., Shuid A.N., Ibrahim N., Jamal J.A., Mohamed N., Mohamed I.N. This fact suggests that other components, such as fiber in the soy foods, may account for these negative associations. Prez-Cornago et al. Despite the positive effect of isoflavones, the authors emphasized that the effects took a long time to appear. The difference for isoflavones required to find an effect can be due to variations in the amount of isoflavone intake between both populations. Discover world-changing science. However, a limitation in this field is that there is still a great heterogeneity among studies. Science is Knowledge Space & Physics The Effects of Moonlight May 22, 1858 Professor Piazza Smyth, the Astronomer Royal for Scotland, in his interesting account of a recent scientific. 2023 Scientific American, a Division of Springer Nature America, Inc. 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. Consensus: Soy isoflavones as a first-line approach to the treatment of menopausal vasomotor complaints. Isoflavones have received attention due to their putative healthy properties. (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]. You J., Sun Y., Bo Y., Zhu Y., Duan D., Cui H., Lu Q. 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 general terms, caution should be exercised with the use of high doses of isoflavones in women with a family history of breast cancer [49]. By contrast, it seems that soy isoflavones do not lead to a meaningful protective effect on cardiovascular risk. For this reason, the results should be interpreted with caution, and more randomized clinical trials are required. 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. Ingram D., Sanders K., Kolybaba M., Lopez D. Case-control study of phyto-oestrogens and breast cancer. The enzymes responsible for the hydrolysis of isoflavone glycosides are glucosidases, which can be produced by the intestinal mucosa or the microbiota [29]. 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. Modified from Mace et al. [12,42]. Isoflavone excretion occurs mainly through urine and feces, primarily in the conjugate forms, and up to 95% takes place in 24 h [43]. (2018), 30 articles were included for analysis; 15 of them were case-control studies, eight cohort studies and seven nested case-control studies [76]. 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. "It's not. Dead or dying trees are a common sight in areas effected by acid rain. Implications of phytoestrogen intake for breast cancer. Murota K., Nakamura Y., Uehara M. Flavonoid metabolism: The interaction of metabolites and gut microbiota. Moreover, five studies reported side-effect data, and after the analysis, no significant differences were observed between the two groups. Chadha R., Bhalla Y., Jain A., Chadha K., Karan M. Dietary Soy Isoflavone: A Mechanistic Insight. In this systematic review, 123 studies were included, with a total number of 516,330 participants. The tides are crucial to life: tidal pools, sheltered and renewed in rhythm with these cycles, catalyzed some of the first stable ecologies and still represent unique niches. Publishers Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Isoflavones Biosynthesis, Occurence and Health Effects. In this section, 16 meta-analyses have been revised: Nachvack et al. (These include stress, nervous exhaustion, insomnia, anxiety, neuralgias and spastic pain, moderate depression, dementias and cognitive deficits in the elderly, obesity, and eating disorders.) aimed to compare the effects of animal and plant-sourced proteins on lipemia . 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]. While equol production seems to be similar in animals, it is very variable in humans [41], and therefore, beneficial effects referred to equol have been observed only in individuals with a specific microbiota composition [38]. HRT: hormone replacement therapy, RCT: randomized controlled trial, VSM: vasomotor symptoms. The authors found a significant inverse association between isoflavone intake and both overall mortality and breast cancer recurrence. Zamora-Ros R., Knaze V., Rothwell J.A., Hmon B., Moskal A., Overvad K., Tjnneland A., Kyr C., Fagherazzi G., Boutron-Ruault M.C., et al. Association of isoflavone biomarkers with risk of chronic disease and mortality: A systematic review and meta-analysis of observational studies. Analysis of isoflavones in Foods. You et al. For this reason, the results should be interpreted with caution, and more randomized clinical trials are required. This difference could explain the slow effect of isoflavones in alleviating hot flushes. PV panels have been linked . 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.

Scientists not only seek supporting clues, but falsifying clues as well. Postprandial lipemia detects the effect of soy protein on cardiovascular disease risk compared with the fasting lipid profile. Study duration ranged from four weeks to two years, with a median of 12 weeks. 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. Li L., Xu L., Wu J., Dong L., Zhao S., Zheng Q. However, more studies are required to provide stronger evidence. 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. With regard to prostate cancer, it has been proposed that it might be affected by isoflavone consumption due to its effect on hormone metabolism. Metabolism of intraruminally administered [4-. 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. Moreover, Rienks et al. government site. In this sense, Micek et al. 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. This finding suggests that bacterial deglycosylation contributes significantly to isoflavone absorption [32]. 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. Rapid activation of MAP kinase by estrogen in the bone cell line. 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. However, the intake of specific isoflavones, genistein and daidzein, was indeed significantly associated with a reduced risk of this type of cancer. Dietary polyphenol intake in Europe: The European Prospective Investigation into Cancer and Nutrition (EPIC) study. 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. 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 addition, several studies have observed that the urine excretion of daidzein metabolites is notably higher than that of genistein metabolites [44,45,46]. 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. 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. 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]. Global climate change is not a future problem. Lastly, Zhang et al. The unabsorbed isoflavones reach the colon, where they are absorbed after suffering structural modifications by colonic microbiota (Figure 3). Presence of four chemical forms of the three isoflavones found in soybeans. (2017) also analyzed eight studies of prostate cancer, and they found an association between isoflavone intake and prostate cancer risk [61].

The Effects and Action Mechanisms of Phytoestrogens on Vasomotor Symptoms During Menopausal Transition: Thermoregulatory Mechanism. (2019) studied whether equol supplementation could benefit equol nonproducer subjects in lowering the incidence and severity of hot flushes [85]. 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]. 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]. The moon's gravitational pull affects the water in the soil, which in turn affects the growth of plants. 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. By contrast, it seems that soy isoflavones do not lead to a meaningful protective effect on cardiovascular risk. Create your free account or Sign in to continue. Soy isoflavones consumption and risk of breast cancer incidence or recurrence: A meta-analysis of prospective studies. The results showed that a higher regular intake of foods rich in isoflavones might potentially decrease colorectal cancer incidence. Rienks J., Barbaresko J., Nthlings U. (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]. Before That's what behavioral ecologist Jenny York learned while studying white-browed sparrow weavers . As it has been stated in the Bioavailability section, microbiota composition in humans makes equol production very variable, which yields high interindividual differences. Soy Consumption and the Risk of Prostate Cancer: An Updated Systematic Review and Meta-Analysis. Federal government websites often end in .gov or .mil. Produced metabolites appear in plasma at variable concentrations and can enter enterohepatic circulation [28]. May affect males and females differently A 2015 study of 205 people found that the full moon may affect sleep differently in males and females. 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. Yu Y., Jing X., Li H., Zhao X., Wang D. Soy isoflavone consumption and colorectal cancer risk: A systematic review and meta-analysis. On the contrary, women who were already equol producers did not obtain any additional benefit from supplements of equol or isoflavones. 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. Oral isoflavone supplementation on endometrial thickness: A meta-analysis of randomized placebo-controlled trials. The dose of isoflavones ranged from 30 to 200 mg/day. In Japanese men, pre-diagnostic circulating levels of genistein, daidzein and equol did not significantly affect prostate cancer risk. Comparative efficacy of nonhormonal drugs on menopausal hot flashes. 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). (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]. The authors suggested that this difference could be due to different genetic backgrounds and dietary patterns among Asian and Western populations. Licensee MDPI, Basel, Switzerland. An official website of the United States government. The light of the moon also influences animals that are active in daytime. However, all the authors agree that further studies are necessary so as to confirm these results. 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]. 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. Due to the high prevalence of colorectal cancer, three meta-analyses addressing this issue are included in the present review. 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]. 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. DOI: 10.1093/OXFORDJOURNALS.AOB.A087491 Corpus ID: 89019113; Effects of Moonlight on Flower Induction in Pharbitis nil, Using a Single Dark Period @article{KadmanZahavi1987EffectsOM, title={Effects of Moonlight on Flower Induction in Pharbitis nil, Using a Single Dark Period}, author={Avishag Kadman-Zahavi and Dovrat Peiper}, journal={Annals of Botany}, year={1987}, volume={60}, pages={621-623} } 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.
