; Project Administration, M.P.P. 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 the systematic review reported by Perna et al. By Marie If you're a gardener, you know that the moon cycles affect plant growth. Focusing on the overall intake of isoflavones in humans, several studies have reported varied results. 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. Franco O.H., Chowdhury R., Troup J., Voortman T., Kunutsor S., Kavousi M., Oliver-Williams C., Muka T. Use of Plant-Based Therapies and Menopausal Symptoms: A Systematic Review and Meta-analysis. Treutter D. Significance of flavonoids in plant resistance and enhancement of their biosynthesis. PV panels have been linked . In this section, 16 meta-analyses have been revised: Nachvack et al. 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. Kim Y., Je Y. Flavonoid intake and mortality from cardiovascular disease and all causes: A meta-analysis of prospective cohort studies. (2017) conducted a meta-analysis with ten observational studies to assess the association between the isoflavone compounds daidzein, genistein and equol, and breast cancer [61]. Lastly, Abshirini et al. Isoflavones are phenolic compounds with a chemical structure similar to that of estradiol. In Japanese men, pre-diagnostic circulating levels of genistein, daidzein and equol did not significantly affect prostate cancer risk. 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]. Ten studies reported a significant reduction in hot flush frequency in the phytoestrogen group when compared with the placebo group. Furthermore, isoflavones are associated with proteins; thus, alcohol extraction and processing diminish isoflavone content in foodstuffs such as fermented soybean, tofu or soy beverages. ); [email protected] (A.F.-Q. Thus, whereas Asian populations have an average isoflavone consumption of >30 mg/day, Western populations consume <1 mg/day [83]. 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. As it has been stated in the Bioavailability section, microbiota composition in humans makes equol production very variable, which yields high interindividual differences. Contraction stimulates translocation of glucose transporter GLUT4 in skeletal muscle through a mechanism distinct from that of insulin. Rienks et al. 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. 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. In the same line, in European men, isoflavone concentrations did not affect the risk of developing prostate cancer. (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]. Licensee MDPI, Basel, Switzerland. Scientists often disagree about certain things. Sarri G., Pedder H., Dias S., Guo Y., Lumsden M.A. 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]. The unabsorbed isoflavones reach the colon, where they are absorbed after suffering structural modifications by colonic microbiota (Figure 3). Juglans regia L. is a traditional plant that has been integrated into traditional medicine since ancient times. In this line, another meta-analysis, which included 52 controlled trials and 5313 patients, shows that soy isoflavones have beneficial effects on bone mineral density in the femur neck, lumbar spine, and hip, regardless of body weight or ethnicity [49]. 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. (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]. Four meta-analyses have been reported to address this issue. . Dietary polyphenol intake in Europe: The European Prospective Investigation into Cancer and Nutrition (EPIC) study. Abshirini M., Omidian M., Kord-Varkaneh H. Effect of soy protein containing isoflavones on endothelial and vascular function in postmenopausal women: A systematic review and meta-analysis of randomized controlled trials. During menopause, there is a loss of bone density that can cause osteoporosis. Winkel-Shirley B. Biosynthesis of flavonoids and effects of stress. Kelly G.E., Nelson C., Waring M.A., Joannou G.E., Reeder A.Y. 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. Moreover, this association was more prominent among postmenopausal women than premenopausal women. 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. Gaya P., Medina M., Snchez-Jimnez A., Landete J.M. 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} } 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. 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. 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]. In addition, it is important to highlight that interindividual differences in gut bacterial populations are responsible for the diverse effects of isoflavones in humans. Franco et al. 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. 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. 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. Metabolites of dietary (soya) isoflavones in human urine. Morning 3: Temp 98.6 BP 124/83 Pulse 62 bpm. In miso and tempeh, the aglycone form is the most abundant one [9]. Soy Consumption and the Risk of Prostate Cancer: An Updated Systematic Review and Meta-Analysis. Phytoestrogen Metabolism by Adult Human Gut Microbiota. Dead or dying trees are a common sight in areas effected by acid rain. 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. Possible mechanism of action of isoflavones for cancer prevention. [12,42]. (2016), nine studies addressed to menopausal women and focused on bone health were analyzed [52]. 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. Another meta-analysis, conducted by Zhao et al. 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]. Modified from Wang et al., 2006 [4]. (2019), included 16 prospective cohort studies involving 11,169 breast cancer cases and 648,913 participants [70]. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. Reduction of the endometrial thickness in North American women (for 0.23 mm). Therefore, the authors concluded that the intake of dietary isoflavones paid a protective role against ovarian cancer. "It's not. However, the moonlight decreases after the full moon. 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 article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (, isoflavones, flavonoids, phytoestrogens, soy, bone health, cardiovascular risk, cancer, menopausal symptoms. However, more studies are required to provide stronger evidence. In fact, the number of isoflavones present was very variable among the different soy food types. Indeed, the dose levels of dietary isoflavones require a better definition, and the measurements of isoflavone consumption should be provided in quantifiable terms. Lambert M.N.T., Hu L.M., Jeppesen P.B. In addition, genistein and glycitein are transformed into dihydrogenistein and dihydroglycitein, respectively, before being further converted into other metabolites. 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. aimed to compare the effects of animal and plant-sourced proteins on lipemia and blood pressure [60]. Menopause is characterized by a decrease in estrogen levels and is often accompanied by a range of symptoms. ; WritingReview and Editing, M.P.P., S.G.-Z., I.E.

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. For this reason, the results should be interpreted with caution, and more randomized clinical trials are required. Perna S., Peroni G., Miccono A., Riva A., Morazzoni P., Allegrini P., Preda S., Baldiraghi V., Guido D., Rondanelli M. Multidimensional Effects of Soy Isoflavone by Food or Supplements in Menopause Women: A Systematic Review and Bibliometric Analysis. 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]. 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. In addition, several studies have observed that the urine excretion of daidzein metabolites is notably higher than that of genistein metabolites [44,45,46].
