Consuming bicarbonate-calcium mineral water, low in sodium, can help manage calcium imbalance and support bone health in perimenopausal women.

The study involved 120 perimenopausal women who consumed 2 liters of a specific bicarbonate-calcium mineral water (Lete) daily for six months. This water was chosen because it is rich in calcium and bicarbonate but low in sodium. The study aimed to determine the impact of this water on bone health and overall metabolism. The participants’ urine and blood serum were analyzed using NMR-based metabolomic procedures. These analyses were conducted to assess the effects of the water not only on calcium metabolism but also on the broader systemic metabolism.

The findings indicated that the Lete water effectively compensated for calcium dysmetabolism and supported bone health and integrity in perimenopausal women. While the study primarily focused on bone metabolism, it also provided insights into the potential system-wide metabolic effects of this specific type of mineral water. This suggests that such water could be a valuable dietary supplement for addressing calcium-related metabolic issues, particularly in perimenopausal women.

Soybean intake can potentially reduce risks of several cancers, type 2 diabetes, osteoporosis, and hot flashes, and it may negatively impact some drug treatments and cause allergies.

This research primarily involves review and analysis of current clinical studies focusing on the benefits and risks of soybean ingredients. The method appears to be a systematic review of various epidemiological studies which were investigating the correlation between soybean consumption and the risk of developing multiple types of cancers including breast, prostate, colorectal, ovarian, and lung cancers. Besides cancer, other common diseases such as type 2 diabetes, osteoporosis, and menopausal symptoms like hot flashes were also investigated. Moreover, any potential adverse effects of soybean, including its possible detrimental impact on certain drug treatments and its allergenicity, were also factors of study in these clinical evidences.

In the discussion of results, the researchers found a significant inverse association between soybean intake and cancer risks, wherein an increase in the consumption of soybean foods was associated with a reduced likelihood of cancer. Besides showing potential anticancer properties, soybean consumption was found inversely correlated with risks of type 2 diabetes. Soy isoflavones, compounds present in soybeans, also showed potential benefits in the management of osteoporosis and hot flashes. On the other hand, the adverse effects of soybean, including interference with certain drug therapies and causing allergies, were also duly noted. Therefore, the research concludes that while soybean promises several significant health benefits, caution should be exercised for individuals under specific drug treatments or with allergies to soy.

Fermented soy milk significantly improves lipid profiles and fertility in a model of premenopausal mice, due to increased bioavailability and action of beneficial compounds.

In this study, non-fermented soy beverage (SB) and soy beverage fermented with Bifidobacterium pseudocatenulatum INIA P815 (FSB) were tested on both cyclic and acyclic C57BL/6J aged female mice which mimic premenopause and menopause conditions respectively. Over a period of 36 days, the beverages were given to the mice and the variables measured included body weight, lipid and inflammatory profile and fertility. In addition, hepatic gene expressions were examined and the faecal microbiota composition was assessed to further understand the effects of the two beverages.

In the results, FSB displayed a higher concentration of the aglycones daidzein and genistein as well as increased antioxidant activity due to the fermentation process. The cyclic mice that were given FSB experienced a significant rise in the number of oocytes and zygotes retrieved. It was also noticed that the triglycerides were lower in the groups that were given FSB compared to the SB groups. However, it was found that neither of the treatments significantly influenced the inflammatory profile or caused a major shift in intestinal microbiota or hepatic gene expressions in either of the groups. Still, it was observed that FSB had more health benefits than SB with regards to the lipid profile and fertility in the cyclic mice, likely due to the increased bioavailability and bioactivity of compounds due to fermentation.

Pomegranate can significantly enhance women's health during and after menopause by reducing hot flashes severity and other menopause symptoms.

The study aimed at understanding the impacts of pomegranate on women's health through and following menopause. To gather data, a rigorous search was conducted on various academic platforms, including PubMed, Web of Science, Cochrane, Scopus, and Google Scholar, up to the end of 2022. All forms of clinical research studies, from randomized clinical trials to case series, were considered for review. The material was evaluated using the Cochrane RoB 2.0 tool specifically for quality assessment of randomized clinical trials. To quantify the effects of the pomegranate intervention, standardized mean differences were calculated using a random effect model.

It was found that pomegranate significantly reduces the severity of hot flashes in menopausal women, improves their high-density lipoprotein levels, and reduces the Follicle-Stimulating Hormone (FSH). However, no significant improvement was noticed in the low-density lipoprotein, body mass index, and body weight. Despite these findings, the study recognized that the results' conclusiveness was hampered due to small sample sizes and the lack of study design elements such as blinding and randomization.

A diet low in fat, vegan, and inclusive of daily cooked soybeans significantly reduces the frequency and severity of hot flashes in postmenopausal women.

The methodology used involved the selection of 84 postmenopausal women who reported at least two moderate-to-severe hot flashes. These women were randomly divided into two cohorts, one prescribed the dietary intervention of a low-fat, vegan diet coupled with daily servings of cooked soybeans and a control group which did not alter their diet. Over a 12-week period, a mobile application was used to track hot flashes in terms of frequency and severity. Further, the participants’ vasomotor, psychosocial, physical, and sexual symptoms were assessed using the Menopause-Specific Quality of Life questionnaire. In some participants, the presence of urinary equol, a compound formed in the gut after consuming soy, was measured following the intake of the specified amount of soybeans for 3 days.

In discussing the results, a remarkable decrease was noted in the frequency and severity of hot flashes experienced by the group assigned the dietary intervention versus those in the control group. In addition, after 12 weeks, half of the participants adhering to the vegan diet and daily soy intake reported complete cessation of moderate-to-severe hot flashes. Furthermore, notable decreases were reported in the intervention group in menopause-specific quality of life domains including vasomotor, physical, and sexual. Neither the season nor the participant's ability to produce equol played a notable role in these improvements.

Phytoestrogens, used in various forms, have shown improvement in urogenital menopause symptoms and improved women's sexual function, promoting overall quality of life.

A thorough and systematic review was conducted on databases including PubMed, EMBASE, Web of Science, Cochrane library, Scopus and ProQuest, spanning from the years 2000-2020. The focus was solely on randomized clinical trials. An evaluation of the quality of selected papers was carried out using the CONSORT checklist. In total, 33 high-quality papers were reviewed which discussed the different forms and uses of phytoestrogens.

The results of this systematic review reveal that phytoestrogens including Pueraria Mirifica, fennel, Hop plant, Glycine Max, soy, red clover, black cohosh, ginsing, cimicifugaracemosa, genistein, diadzein, glycitein and isoflavone, used as various products such as oral capsules, pills, food supplements, enriched powders, vaginal gels, creams and suppositories, improved menopausal urogenital symptoms. Particularly, the recovery rate was found to be higher when these were applied vaginally. Further implication of these findings is the enhancement of women's sexual function following treatment, validating the use of phytoestrogens as a safe, low-risk and accessible method to alleviate urogenital symptoms.

Moderate daily consumption of beer, both with and without alcohol, can significantly alleviate menopause-related symptoms and improve cardiovascular health in postmenopausal women.

In the research, 37 postmenopausal women were voluntarily put through a parallel controlled intervention trial, involving three study groups. The trial involved 16 women consuming beer with alcohol (330 mL/day), 7 women consuming non-alcoholic beer (660 mL/day), and 14 women as control.

In assessing the results, it was found that both interventions, beer with and without alcohol, substantially reduced the severity of menopause-associated symptoms. Specifically, beer with alcohol positively contributed to reducing psychological discomforts linked to menopause when compared to the control group. It was additionally noted that these beneficial effects could be traced to the non-alcoholic section of the beer, as the sex hormone profile remained largely unchanged across the different study groups. In addition, the group that consumed non-alcoholic beer conveyed improvements in their lipid profiles and exhibited lower blood pressure levels, indicating better cardiovascular health.

Acupuncture is non-inferior to hormone therapy or other applied relaxation therapies in alleviating the symptoms of menopause for its safety, non-invasive and especially considering the side effect of hormone therapy.

This meta-analysis of women with breast cancer confirms that acupuncture had no significant effect on the severity of hot flush, but did significantly alleviate the symptoms of menopause. We conclude that acupuncture is non-inferior to hormone therapy or other applied relaxation therapies in alleviating the symptoms of menopause for its safety, non-invasive and especially considering the side effect of hormone therapy. Recent studies show that use of acupuncture does not correlate with increased levels of plasma estradiol. Considering the safety and lack of serious adverse effects associated with acupuncture, in contrast to hormone therapy, acupuncture should be considered for treating hot flush and menopause syndrome in women with breast cancer.

Both the total score and the subgroup analysis strongly indicated that acupuncture can alleviate menopause-related symptoms.

Six studies were included. Our analysis found that acupuncture can reduce the MRS score in menopausal women by the end of the treating period (2-3 months, on average) and even in the follow-up period (1-3 months), not only in the total score but also in each subscale score. But the grade of evidence is very low.

Both the total score and the subgroup analysis strongly indicated that acupuncture can alleviate menopause-related symptoms. However, the evidence is not very strong. Thus, further studies about the efficiency of acupuncture on menopausal symptoms based on well-designed trials are needed.

Moderate beer consumption could potentially alleviate menopausal symptoms by influencing the internal estrogen receptors through the phenolic compounds present in beer.

The study used the developments in food analysis techniques over the past two decades to explore the correlation between the intake of polyphenols from moderate beer consumption and the relief of vasomotor symptoms often experienced during menopause. The focus was on phenolic compounds present in beer like 8-prenylnaringenin, 6-prenylnaringenin, and isoxanthohumol and how they interact directly with intracellular estrogen receptors to influence gene expression and sex hormone plasma concentrations.

The observed results pointed to the potential positive effects of moderate beer consumption on menopausal symptoms. It was inferred that phenolic compounds in beer could interact directly with intracellular estrogen receptors, leading to a modulation of gene expression, thereby balancing physiological hormone imbalance in menopausal women. This alternative could serve as a safer option for alleviating menopausal symptoms as traditional hormone replacement therapies have known health risks. However, these findings need to be viewed keeping in mind the implications of beer consumption on overall health.

The study's analysis of 272 articles comparing Traditional Chinese Acupuncture (TCA) and Sham Acupuncture (SA) for managing hot flashes in menopausal breast cancer patients indicates that while 3 studies leaned towards TCA's effectiveness, 2 showed both interventions to be beneficial.

The study encompassed the analysis of 272 articles from five selected databases, resulting in the inclusion of five manuscripts meeting the eligibility criteria. The primary focus was on comparing the efficacy of Traditional Chinese Acupuncture (TCA) to Sham Acupuncture (SA) in managing hot flashes among menopausal women with breast cancer. Among the selected studies, three indicated that TCA was more effective in reducing the frequency and intensity of hot flashes, while two found both interventions to be beneficial, though not significantly distinct. These studies exhibited considerable diversity in their designs, sample sizes, treatment durations, and acupuncture protocols. TCA appeared to hold promise in mitigating hot flashes, yet several methodological limitations and potential biases within the reviewed studies were noted. Consequently, there's a call for further comprehensive, large-scale, and long-term trials to elucidate TCA's true potential and overcome the limitations observed in the current body of research.

Hop extract, particularly its component 8-Prenylnaringenin (8-PN), demonstrates potential in alleviating symptoms common in menopause such as osteoporosis, vasomotoric disturbances, and sexual motivation.

The methodology of this research involved identifying the major constituents of hop extract, with a focus on 8-Prenylnaringenin (8-PN) due to its estrogenic qualities. Several in vivo studies were conducted to explore the potential of hop extract and 8-PN in mitigating climacteric symptoms. Clinical studies conducted have mainly centered around menopausal discomforts, still, these studies provided broad results.

In the discussion of the results, it was found that hop extract, and more prominently, 8-PN, show promise in alleviating menopausal symptoms such as osteoporosis, vasomotoric issues, and sexual desire. Although 8-PN primarily activates the estrogen receptor α and presents only slight uterotrophic attributes, it also brings about estrogenic effects on the mammary gland. The results indicate potential application of 8-PN and hop extract in alleviating symptoms commonly associated with menopause.

Soybean isoflavones, whether extracted or synthesized, prove significantly effective in reducing the frequency and severity of hot flashes in perimenopausal and postmenopausal women.

The examination in this study began with a database search on PubMed and The Cochrane Controlled Clinical Trials Register for articles shedding light on double-blinded randomized controlled trials conducted until December 14, 2010. Additionally, the authors kept a keen eye out for other peer-reviewed articles containing potentially useful information. Any articles discovered were scrutinized for information on the effects of isoflavones on the frequency or severity of hot flashes in comparison to a placebo. 19 trials were found suitable for inclusion in a systematic review, while 17 of these made it to the meta-analysis stage.

Among the 19 trials under review, data revealed that soybean isoflavones' ingestion, on a median of 54 mg for 6 weeks to 12 months, seemed to lead to a decrease in the frequency of hot flashes. A similar trend was discerned with hot flash severity, which reportedly reduced with isoflavone intake. Interestingly, it was found that isoflavone supplements with over 18.8 mg of genistein were more than twice as powerful in reducing hot flash frequency as supplements with a lower genistein count. These results, compiled over the course of the study, strongly suggest that soy isoflavone supplements are quite effective in mitigating the issue of hot flashes in perimenopausal and postmenopausal women.

Pumpkin seed oil supplementation may increase good cholesterol levels, lower diastolic blood pressure, and alleviate menopausal symptoms in postmenopausal women.

In this pilot study employing a randomized, double-blinded and placebo-controlled design, 35 women that were either naturally menopausal or had prematurely entered menopause due to benign surgical intervention partook. Over the span of 12 weeks, participants received either pumpkin seed oil or wheat germ oil (serving as the placebo) at a dosage of 2 grams daily. Measurements of serum lipids, fasting plasma glucose, blood pressure and completion of a questionnaire regarding menopausal symptoms were taken before and after the supplementation period, and changes across these factors were evaluated.

Following supplementation, women who received pumpkin seed oil displayed increased concentrations of high density lipoprotein cholesterol (commonly known as good cholesterol) and a reduction in diastolic blood pressure. Additionally, there was a notable decline in the severity of menopausal symptoms, including hot flushes, headaches, and joint pain, thanks to this supplementation. Contrarily, symptoms of depression and feelings of being unloved heightened among women in the group that received wheat germ oil.

Gui-zhi-fu-ling-wan, a traditional Chinese medicine, can effectively alleviate hot flashes in young patients in a safe manner.

For the methodology, this study was conducted retrospectively, examining the medical records of patients who visited the Department of Cardiovascular and Neurologic Disease, Kyung Hee Oriental Medical Center for hot flashes from between October 1, 2003, to October 1, 2008. Out of 60 cases reviewed, 37 were selected based on the inclusion criteria. The primary measure of improvement was assessed using the visual analog scale.

In the discussion of results, it was noted that the mean improvement in symptoms was significant and a majority of patients experienced a 50% improvement. The secondary analysis revealed that the outcomes of differential diagnosis of cold and hot syndrome and blood stasis syndrome did not affect the scores. Importantly, only a trivial percentage of patients reported adverse events, indicating that Gui-zhi-fu-ling-wan may be a safe therapy for hot flashes.

Gui-zhi-fu-ling-wan, a herbal therapy, depicts to be a viable alternative to hormone replacement therapy for treating hot flashes in post-menopausal women experiencing coldness in lower extremities.

In this study, an examination of the connection between extremities' blood flow and hot flashes was conducted among 352 post-menopausal women aged between 46 and 58 who were showing climacteric complaints. 131 of these women, who were experiencing hot flashes, were treated either with HRT or Gui-zhi-fu-ling-wan, a type of herbal therapy. This investigation measured blood flow under the jaw, in the middle finger, and the third toe using laser doppler fluxmetry.

Subsequent to the therapies, there was a notable decrease in the heightened blood flow under the jaw that is associated with hot flashes. However, the herbal therapy, Gui-zhi-fu-ling-wan, interestingly, increased blood flow in the lower extremities while the hormone replacement therapy did not. This suggests that Gui-zhi-fu-ling-wan does not uniformly affect the activity of the vasodilator neuropeptides on the sensory neurons of systemic peripheral vessels, thereby proving more effective in treating hot flashes accompanied with cold lower extremities.
