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.

Randomised Controlled Trial Hot Flushes Low Fat Diet Menopause
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.
Isoflavones found in soybeans can reduce risks of certain cancers and alleviate menopause-related symptoms among women, such as vasomotor syndromes, spinal bone loss, and hypertension.

The study overviewed soybeans' chemical composition and focused mainly on isoflavones. The research examined the processes of soybean preparation that includes cleaning, drying, crushing, and dehulling, and extraction methods to derive various soy products, particularly focusing on isoflavones - daidzein, genistein, and S-equol. Various soy products such as refined soy oil, soy lecithin, free fatty acids, glycerol, and soybean meal were discussed, along with the presence of the minor biological constituents in remaining components.
The study explored the relationship between isoflavone consumption and disease prevention, particularly in relation to heart disease, cancer incidence—of the breast, bladder, and endometrial and colorectal—and menopause-related symptoms. The therapeutic effects of isoflavones were studied in the context of vasomotor syndromes, spinal bone loss, hypertension regulation, depressive symptoms during pregnancy, and in vitro glycemic control. In contrast, it failed to find definitive effects of isoflavones on cognition improvement and urogenital symptoms. The inconsistencies in defining the ingredients, doses, study durations, and outcomes of isoflavone studies proved challenging for the research.
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.
