scientific evidence regarding the effects of moonlight on plants

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. Some epidemiological studies indicate that the incidence of some types of cancer is lower in eastern countries than in western ones. It follows that additional high-quality, large-scale randomized controlled trials are needed. 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. Vlachopoulos C., Aznaouridis K., Stefanadis C. Prediction of cardiovascular events and all-cause mortality with arterial stiffness: A systematic review and meta-analysis. (2015) concluded that soy isoflavones have both a slight and slow effect in attenuating menopausal hot flushes [87]. The authors found a significant inverse association between isoflavone intake and both overall mortality and breast cancer recurrence. and transmitted securely. CVD: cardiovascular disease, LDL: low-density lipoprotein. The authors studied all possible correlations between isoflavone consumption and the risk of breast cancer. Soy isoflavones osteoprotective role in postmenopausal women: Mechanism of action. Daidzein is first converted into dihydrodaidzein, which is the precursor of both equol and O-demethylangolensin (O-DMA) [37]. Isoflavone content in soy-derived products is usually lower than in soybeans [17]. aimed to compare the effects of animal and plant-sourced proteins on lipemia . (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]. 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. Others, however, consider such notions as prime examples of "New Age freakery". (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]. (2016), nine studies addressed to menopausal women and focused on bone health were analyzed [52]. Additionally, Yan and co-workers, in their meta-analysis with a total of ten prospective cohorts and seven case-control studies (including 508,841 participants and 17,269 cardiovascular disease events), observed that the consumption of soy foods, but not that of isoflavones, was associated with a lower risk of total cardiovascular disease (including coronary heart disease and stroke) [57]. 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. In the end, isoflavones could be useful in reducing hot flushes associated with menopause. Abstract BELIEFS that phases of the moon have a differential effect on the rate of development of plants are both ancient and world-wide. Liu J., Yuan F., Gao J., Shan B., Ren Y., Wang H., Gao Y. However, it is important to point out that the beneficial effects of soy isoflavone consumption have been exhibited by women with estrogen receptor-negative breast cancer, but not by women with receptor-positive breast cancer, who present a better prognosis [62]. Possible mechanism of action of isoflavones for menopausal symptoms. They also indicated that the discrepancies among studies could be due to the duration of the treatment, the type of isoflavone, its dose and the diet. Daily et al. (2019) studied whether equol supplementation could benefit equol nonproducer subjects in lowering the incidence and severity of hot flushes [85]. official website and that any information you provide is encrypted Contraction stimulates translocation of glucose transporter GLUT4 in skeletal muscle through a mechanism distinct from that of insulin. (2016) included 17 studies (nine case-control studies and eight cohort studies) [80]. Daidzein, genistein and glycitein occur naturally in the aglycone form, and thus their absorption is faster than that of others. Bethesda, MD 20894, Web Policies Gaya P., Medina M., Snchez-Jimnez A., Landete J.M. In miso and tempeh, the aglycone form is the most abundant one [9]. Magee P.J. In this section, 16 meta-analyses have been revised: Nachvack et al. 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. Explore our digital archive back to 1845, including articles by more than 150 Nobel Prize winners. There are a total of 15 3 = 3375 possible outcomes. 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. Acid rain also removes minerals and nutrients from the soil that trees need to grow. In general, evidence regarding the use of isoflavones on vasomotor symptoms suggests that they could be useful in reducing hot flushes.

(2017) conducted a meta-analysis with 21 case-control studies and two cohort studies, with a total number of 11,346 cases and 140,177 controls [77]. As it has been stated in the Bioavailability section, microbiota composition in humans makes equol production very variable, which yields high interindividual differences. Duffy C., Perez K., Partridge A. For this reason, the results should be interpreted with caution, and more randomized clinical trials are imperative. Inverse association between isoflavone consumption and colorectal cancer risk in case-control studies, but not in cohort studies. The most significant food source of isoflavones in humans is soy-derived products. Regarding this topic, three systematic reviews and three meta-analyses were analyzed (Table 2). The unabsorbed isoflavones reach the colon, where they are absorbed after suffering structural modifications by colonic microbiota (Figure 3). Matulka R.A., Matsuura I., Uesugi T., Ueno T., Burdock G. Developmental and Reproductive Effects of SE5-OH: An Equol-Rich Soy-Based Ingredient. Acid rain leaches aluminum from the soil.

Perna et al. Kim Y., Je Y. Flavonoid intake and mortality from cardiovascular disease and all causes: A meta-analysis of prospective cohort studies. At high elevations, acidic fog and clouds might . (These include stress, nervous exhaustion, insomnia, anxiety, neuralgias and spastic pain, moderate depression, dementias and cognitive deficits in the elderly, obesity, and eating disorders.) That's what behavioral ecologist Jenny York learned while studying white-browed sparrow weavers . However, the moonlight decreases after the full moon. Endometrial cancer (Table 4), as well as breast cancer, is an estrogen-dependent cancer type related to high circulating estradiol concentrations. 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. Dead or dying trees are a common sight in areas effected by acid rain. The meta-analysis included 15 studies in which the number of participants ranged from 30 to 252. Nevertheless, it is important to consider this metabolite since it is key in the biological activity of isoflavones [13]. 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. 2023 Scientific American, a Division of Springer Nature America, Inc. Looking at a few examples of moonlight's. 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. Lastly, Zhang et al. A systematic review and meta-analysis of the effects of isoflavone formulations against estrogen-deficient bone resorption in peri- and postmenopausal women. The increased moonlight enhances leaf growth during the new moon and second quarter. Barnes S. The biochemistry, chemistry and physiology of the isoflavones in soybeans and their food products. The physical stiffening of arteries has major health implications for its connection to various adverse cardiovascular and other health outcomes such as coronary heart disease, stroke, hypertension or heart failure [66]. A total of 16 studies were included in their meta-analysis with a range of 24 to 236 subjects. 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. In the aforementioned mechanism, it has been reported that isoflavones bind to both ER and ER, although they present a higher affinity towards ER receptors [7]. Influence of cellular ERalpha/ERbeta ratio on the ERalpha-agonist induced proliferation of human T47D breast cancer cells. Discover world-changing science. [(accessed on 21 September 2020)]; Messina M., Nagata C., Wu A.H. 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. Overall, evidence regarding the use of isoflavones in cancer prevention suggests that they may be useful in reducing the risk of suffering from some types of cancer, such as breast and endometrial cancer, two of the types for which the association between isoflavone intake and cancer risk has been studied more in-depth. After this, each metabolite undergoes its own metabolic pathway [40]. Soy products (0.05130 g/day) and total isoflavones (0.28 to 63 mg/day). Furthermore, isoflavones are associated with proteins; thus, alcohol extraction and processing diminish isoflavone content in foodstuffs such as fermented soybean, tofu or soy beverages. Conceptualization, S.G.-Z. 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. Zaheer K., Humayoun Akhtar M. An updated review of dietary isoflavones: Nutrition, processing, bioavailability and impacts on human health. In addition, Qiu et al. 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. In fact, the number of isoflavones present was very variable among the different soy food types. 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. A significant 19% reduction of the risk was found at high concentrations of daidzein, but not at genistein or equol concentrations. (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]. Metabolism of intraruminally administered [4-. Sotoca A.M., van den Berg H., Vervoort J., van der Saag P., Strm A., Gustafsson J.A., Rietjens I., Murk A.J. Cheynier V., Sarni-Manchado P., Quideau S., editors. The authors reported that neither soy food intake nor circulating isoflavones were associated with a reduced risk of prostate cancer. 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. 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, this association was more prominent among postmenopausal women than premenopausal women. Lastly, Abshirini et al. While a moderate intake of soy isoflavones did not significantly affect breast cancer risk, a significant reduction was shown when the intake was high. Association between Dietary Isoflavones in Soy and Legumes and Endometrial Cancer: A Systematic Review and Meta-Analysis. Global climate change is not a future problem. Modified from Mace 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.
