scientific evidence regarding the effects of moonlight on plantsscientific evidence regarding the effects of moonlight on plants

Franco et al. Moreover, sodium-dependent glucose transporter 1 (SGLT1) allows phenolic compound-glycosylates to directly enter into epithelial cells, where they are hydrolyzed by cytosolic glucosidases [30,31]. 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. However, more studies are required to provide stronger evidence. 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]. Even though red clover has a greater amount of isoflavones, it is not an edible plant, and it is consumed as a food complement. Dietary isoflavones or isoflavone-rich food intake and breast cancer risk: A meta-analysis of prospective cohort studies. In the last few decades, scientific evidence has stressed the importance of plants in the prevention and/or supportive treatment of a plethora of diseases, many of them chronic, age-associated disorders. In this regard, it has been reported that isoflavones have a higher affinity to the -estrogen receptor [7], which, contrary to the -estrogen receptor, inhibits cell proliferation and stimulates apoptosis [84]. Discover world-changing science. However, the authors pointed out several limitations of this study, such as the important source of heterogeneity in their study. 8600 Rockville Pike Dietary polyphenol intake in Europe: The European Prospective Investigation into Cancer and Nutrition (EPIC) study. Chemical structure of 17-estradiol. This fact suggests that other components, such as fiber in the soy foods, may account for these negative associations. (2016) included 17 studies (nine case-control studies and eight cohort studies) [80]. With regard to isoflavone content in foodstuffs, it has been observed that in soybeans, the amount of these phenolic compounds ranges from 1.2 to 4.2 mg per g on dry weight, whereas in red clover, the amount varies between 10 and 25 mg per g on dry weight [15,16]. Is equol production beneficial to health? Prez-Cornago et al. 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. Thanks for reading Scientific American. Rienks J., Barbaresko J., Nthlings U. Saloniemi H., Whl K., Nyknen-Kurki P., Kallela K., Saastamoinen I. Phytoestrogen content and estrogenic effect of legume fodder. A total of 16 studies were included in their meta-analysis with a range of 24 to 236 subjects. Rienks et al. As in the case of other phenolic compounds, genistein and daidzein undergo phase II xenobiotic metabolism, mainly glucuronidation and sulfation reactions at 4and/or 7 positions of the isoflavone ring [34,35]. Isoflavone content in soy-derived products is usually lower than in soybeans [17]. Moreover, the authors suggested that ethnicity could have had influenced this association, but studies with larger sample sizes are needed to confirm this hypothesis. Isoflavones have received attention due to their putative healthy properties. The gravitational attraction between the Earth and the Moon produces two bulges in the ocean on opposite sides of the Earth. In addition, it is important to highlight that interindividual differences in gut bacterial populations are responsible for the diverse effects of isoflavones in humans. For this reason, the results should be interpreted with caution, and more randomized clinical trials are required. 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. By contrast, it seems that soy isoflavones do not lead to a meaningful protective effect on cardiovascular risk. In fact, the number of isoflavones present was very variable among the different soy food types. (2016) conducted a meta-analysis of 18 studies involving 16,917 colorectal cancer cases in 559,486 participants [78]. In this line, three meta-analyses were conducted to study isoflavone consumption and endometrial cancer risk. 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. van der Schouw Y.T., Kreijkamp-Kaspers S., Peeters P.H., Keinan-Boker L., Rimm E.B., Grobbee D.E. The meta-analysis included 15 studies in which the number of participants ranged from 30 to 252. Wang X., Dykens J.A., Perez E., Liu R., Yang S., Covey D.F., Simpkins J.W. ; WritingReview and Editing, M.P.P., S.G.-Z., I.E. Equol is produced from the isoflavone daidzein by intestinal bacteria, mainly in the large intestine. and J.T. Concerning this issue, six meta-analyses and two systematic reviews are included in the present review (Table 5). 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. 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). Ronis M.J., Little J.M., Barone G.W., Chen G., Radominska-Pandya A., Badger T.M. Isoflavone excretion occurs mainly through urine and feces, primarily in the conjugate forms, and up to 95% takes place in 24 h [43]. It supports the evidence that isoflavones can moderately attenuate bone resorption in women with low estrogen levels, primarily at the level of the lumbar spine and the femoral neck. You et al. 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]. Estimated Asian adult soy protein and isoflavone intakes. 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]. 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. 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). Santo A.S., Santo A.M., Browne R.W., Burton H., Leddy J.J., Horvath S.M., Horvath P.J. The main forms of conjugates in soybeans are the malonyl derivatives [14]. Liu J., Yuan F., Gao J., Shan B., Ren Y., Wang H., Gao Y. 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. Furthermore, soy protein has been linked to an improvement in nitric oxide production and contributes to increased arterial compliance [65]. 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]. In addition, genistein and glycitein are transformed into dihydrogenistein and dihydroglycitein, respectively, before being further converted into other metabolites. Despite the positive effect of isoflavones, the authors emphasized that the effects took a long time to appear. 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. During menopause, there is a loss of bone density that can cause osteoporosis. 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. Possible mechanism of action of isoflavones for menopausal symptoms. Oral isoflavone supplementation on endometrial thickness: A meta-analysis of randomized placebo-controlled trials. Jiang R., Botma A., Rudolph A., Hsing A., Chang-Claude J. Phyto-oestrogens and colorectal cancer risk: A systematic review and dose-response meta-analysis of observational studies. 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. In some Asian countries, isoflavone intake, usually derived from soy consumption, can be associated with a lower prevalence of cardiovascular diseases (CVDs). 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]. However, a limitation in this field is that there is still a great heterogeneity among studies. In the systematic review reported by Perna et al. 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]. It follows that additional high-quality, large-scale randomized controlled trials are needed. Isoflavones are found in several vegetables, mainly in legumes (Fabaceae family) such as soy, white and red clover, alfalfa and beans [9,10]. 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. 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. Acid rain also removes minerals and nutrients from the soil that trees need to grow. (2019) conducted a meta-analysis where 23 prospective studies with a total of 330,826 participants were included. Abdi et al. Soy isoflavones osteoprotective role in postmenopausal women: Mechanism of action. Barnes S. The biochemistry, chemistry and physiology of the isoflavones in soybeans and their food products. 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). 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. The most significant food source of isoflavones in humans is soy-derived products. (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]. Sulfation of the isoflavones genistein and daidzein in human and rat liver and gastrointestinal tract. In addition, several studies have observed that the urine excretion of daidzein metabolites is notably higher than that of genistein metabolites [44,45,46].

The authors observed that soy isoflavone consumption was inversely associated with cancer deaths. official website and that any information you provide is encrypted Grosso et al. 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]. 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. Further, Chalvon-Demersay et al. 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. 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. 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. For their meta-analysis, Jiang et al. Lambert M.N.T., Hu L.M., Jeppesen P.B. Many females sleep less and have less REM sleep. Furthermore, isoflavones are able to inhibit aromatase activity, the enzyme that converts androgen to estrogen. This fact was not taken into account in previous meta-analyses, and thus it may justify the discrepancies amongst them. (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 light of the moon also influences animals that are active in daytime. 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. Zhong X.S., Ge J., Chen S.W., Xiong Y.Q., Ma S.J., Chen Q. 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. 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. 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. Kim Y., Je Y. Flavonoid intake and mortality from cardiovascular disease and all causes: A meta-analysis of prospective cohort studies. Although the mechanisms of action of isoflavones are not completely understood, it seems that isoflavones not only reduce the rate of bone resorption but also increase the rate of bone formation. ); sue.uhe@zelaznog.enatiam (M.G.-A. Moonlight sonata. (2017) carried out a meta-analysis of 143 case-control studies, where isoflavone intake was associated with endometrial, ovarian, and breast cancers [73]. Thus, its consumption, according to epidemiological and clinical studies, has been postulated to be related to a decrease in the risk of different diseases. Beneficial role of dietary phytoestrogens in obesity and diabetes. Regarding the mechanisms by which isoflavones act to alleviate vasomotor symptoms, is has been proposed that they bind to estrogen receptors and activate endothelial nitric oxide synthase (eNOS) transcription, leading to eNOS synthesis and nitric oxide production, the main mediator of vasodilatation, which allows cutaneous heat dissipation [91] (Figure 6). Bethesda, MD 20894, Web Policies Background Climate change and the current phase-out of fossil fuel-fired power generation are currently expanding the market of renewable energy and more especially photovoltaic (PV) panels.

Lastly, Zhang et al. Although results vary greatly, most of these applications are supported by at least a few clinical studies. He X., Sun L.M. In: Thompson M.J., editor. Another meta-analysis, conducted by Zhao et al. Acid rain leaches aluminum from the soil. Applegate C.C., Rowles J.L., Ranard K.M., Jeon S., Erdman J.W. 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. Received 2020 Nov 30; Accepted 2020 Dec 15. 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. 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. Potential health adverse effects in the intake of isoflavones have been postulated due to their estrogenic activity, especially in relation to breast cancer. 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. Influence of cellular ERalpha/ERbeta ratio on the ERalpha-agonist induced proliferation of human T47D breast cancer cells. Effects of isoflavones in different cancer types. So long ago as 1880 Siemens showed that continuous exposure to arc lamps promoted luxuriance of foliage . Bacterial metabolites of isoflavones forming in the gut. 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]. 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. In like manner, a meta-analysis by Simental-Menda et al. Due to the presence of biologically active compounds, walnut was used in the . In contrast, it seems that isoflavones do not act on central neurotransmitters directly. In contrast, red clover was not associated with changes in the hot flush frequency. Efficacy of phytoestrogens for menopausal symptoms: A meta-analysis and systematic review. Consequently, isoflavones can have estrogenic or anti-estrogenic effects [3]. In soybeans, the three most abundant isoflavones are present in four chemical forms: aglycone, glycoside, acetylglycoside and malonylglucoside (Table 1 and Figure 2). 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. In this sense, Micek et al. Qiu S., Jiang C. Soy and isoflavones consumption and breast cancer survival and recurrence: A systematic review and meta-analysis. aimed to compare the effects of animal and plant-sourced proteins on lipemia and blood pressure [60]. Daidzein, genistein and glycitein occur naturally in the aglycone form, and thus their absorption is faster than that of others. Possible mechanism of action of isoflavones for cancer prevention. 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. These two associations were significant for postmenopausal participants. Interestingly, soy protein isolate (void of isoflavones through alcoholic extraction during the protein solation phase) did not show these effects. Hence, plants grow faster and healthier. By contrast, the total isoflavone amount is high in soy flour, protein isolate or edamame [19]. 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]. In Japanese men, pre-diagnostic circulating levels of genistein, daidzein and equol did not significantly affect prostate cancer risk. . Apparently, soy isoflavones modified adhesion molecules by binding to vascular endothelium and mimicking the effect of a modulator of estrogen receptors [64]. FOIA In the meta-analysis reported by Applegate et al. The results indicated that the isoflavone intake decreased the ovarian cancer risk by 33%. (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]. 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. 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. 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. Among these, vasomotor symptoms comprising hot flushes and night sweats are the most common and bothersome, which, in turn, have a negative impact on womens quality of life.
