Estrogenic activity of fermented soymilk extracts and soy compounds
2023 Dec Applied Food Research Nishi K, Imamura I, Takemoto T, Iga K, Kiyama R
The study demonstrates the estrogenic activity of soymilk extracts and soy compounds, with greater activity observed after fermentation, highlighting complex mechanisms at the transcription level. RNA-sequencing analysis revealed up-regulation of genes related to cell division/cell cycle and DNA replication/DNA repair and down-regulation of genes associated with autophagy, suggesting enhanced cell proliferation. The estrogenic activity of soymilk extracts and soy flavonoids, especially after fermentation, offers potential pharmacological benefits, including bone protection, cancer chemoprevention, neuroprotection, and the treatment of menopausal syndromes.

Animal Study Menopause Soybean
The study employed an ovariectomized rat model to understand the effects of a combination of soybean germ extract containing 30% isoflavone and a probiotic. The methodology included assessing the effects of this combination on several health markers including body weight, estrogen markers, uterine and bone health, vascular markers, and neurotransmitter levels in these rats.
Once implemented, the combination of soybean germ extract and the probiotic showcased significant improvement in body weight and uterine and bone health of the rats. There were also noticeable effects on the lipid profile, liver function, and vascular markers. Most interestingly, the combination had a positive impact on the levels of serotonin and norepinephrine, indicating potential mood-enhancing effects, which are crucial in managing symptoms post-menopause. This essentially shows the potential of a dietary approach towards menopausal management, especially given the observed benefits without the side effects typically associated with hormone replacement therapy.

Animal Study Depression Ge Gen Soybean
The researchers focused on Pueraria lobata roots and Glycine max (also known as soybeans) extracts, which are rich in isoflavones but often limited in practical use due to their high molecular weight and low bioavailability. The researchers chose to ferment these extracts with Lactiplantibacillus plantarum strains which are known to convert glycosides to aglycones, potentially enhancing the beneficial effects of the isoflavones. Specifically, the study was conducted using ovariectomized mice.
The research found that both fermented Pueraria lobata root extract and Glycine max extract exhibited estrogen-like activities. More intriguingly, the fermentation process increased the expression of estrogen receptor beta, suggesting that these extracts may not increase the risk of various female cancers—a common side effect of hormone replacement therapy—as was previously believed. Also, the ingestion of these extracts not only increased the estrogen receptor beta in the mice but also upregulated the expression of the brain-derived neurotrophic factor in the hippocampal region of the brain, thus improving depressive symptoms. The highest expression was observed in the group given a mixture of both extracts.

Experimental Study GABA Jujube Sleep
Methodology: An aqueous extract of jujube seeds (ZW) was fermented, following a starch-removing enzymatic degradation process, to increase its γ-aminobutyric acid (GABA) content, resulting in a fermented product (ZW-FM). The sleep-promoting effect of ZW-FM was evaluated using rodent models; specifically, sleep tests were performed on ICR mice with pentobarbital-induced sleep, while the electroencephalography analysis was undertaken in Sprague Dawley rats. Awakening relief effects of ZW-FM were assessed using a caffeine-induced insomnia model. To understand the mechanism, GABA receptor type A (GABA) antagonists were used.
Results: The groups given ZW-FM treatment displayed a longer sleep duration, particularly increased δ-wave time during non-rapid eye movement sleep, and reduced sleep latency. Particularly, the model treated with ZW-FM showed an increase in non-rapid-eye-movement sleep and a reduction in the REM sleep duration, brought about by caffeine treatment. The enhanced sleep induction caused by ZW-FM was hindered by GABA receptor antagonists, thereby validating the involvement of a GABAergic mechanism in promoting sleep.

Animal Study Gut Microbiota Menopause Miso
The study involved using four different types of traditionally made Doenjang (TMD), distinguished based on the quantities of certain species and biogenic amines they contained. These were used to observe possible alterations in energy, glucose, and lipid metabolism in estrogen-deficient female rats via potential modification of the gut microbiota. This involved comparing a control group of rats that underwent ovary removal with five other groups that were supplemented with different types of TMD and cooked soybeans.
The outcomes revealed that weight gain and visceral fat mass were lower and lean body mass was higher in the TMD and cooked soybean intake groups compared to the control group, however, these figures were not as good as those in the normal control group. Additionally, the hepatic triglyceride content was lower with TMD intake. It was further observed that the intestinal health significantly improved in the TMD groups, and some groups revealed more improvements than others. Concerning gut microbiota, certain groups showed an increase in certain types of organisms, suggesting a benefit from high amounts of the specific species in TMD. The study inferred that TMD rich in certain species correlates positively with the regulation of estrogen-related markers.
Unpasteurised milk and dairy products intake could potentially alter gut microbiome composition which may influence psychological functioning.

Experimental Study Gut Microbiota Lactobacillus Raw Milk
In this observational study, the impact of dietary change involving unpasteurized dairy consumption on gut microbiota and psychological state was observed among participants of a 12-week residential cookery course on an organic farm. Twenty-four participants, who primarily consumed food from the farm including unpasteurised milk and dairy products, provided faecal samples at the beginning and end of the course. Concurrently, they completed self-report questionnaires touching on mood, anxiety, and sleep aspects and nutrient intake was monitored via a food frequency questionnaire. Gut microbiota analysis was carried out using 16S rRNA gene sequencing and measurement of faecal short chain fatty acids.
Post-course, there was a significant growth in the relative abundance of a specific bacterial genus in the gut, associated with unpasteurised milk and dairy product intake. Furthermore, an increase in a particular faecal short chain fatty acid, valerate, was observed together with an elevation in the functional richness of the microbiome profile. The latter was determined by measuring the predicted neuroactive potential using a unique gut-brain module approach. Despite safety concerns, the consumption of unpasteurised milk and dairy products seemed to promote the growth of probiotic bacterial genus, known to be beneficial for various physical and mental health outcomes.

A Experimental Study published in 2020 in the journal Journal of Dairy Science found that Lactic acid bacteria strains isolated from indigenous Bangladeshi raw milk demonstrate strong probiotic potential and antimicrobial activity against various pathogens. The researchers isolated and evaluated lactic acid bacteria (LAB) from raw milk indigenous to Bangladesh, focusing on its probiotic potential. To do this, they conducted a series of tests examining the LAB’s antagonistic activity towards several harmful foodborne pathogens, their survivability under gastric conditions, tolerance to phenol and bile salts, adhesiveness to ileum epithelial cells, aggregation abilities, hydrophobicity and α-glucosidase inhibitory activity. They also assessed these strains’ antibiotic susceptibility, covering key antibiotics widely used in medical and veterinary practices. The research spotlighted four LAB strains, identified as Lactobacillus casei, Lactobacillus plantarum, Lactobacillus fermentum, and Lactobacillus paracasei, as possessing strong probiotic potential. This was primarily due to their shown ability to inhibit all tested pathogens to varying degrees and competitively exclude pathogens at certain viable counts. Their antimicrobial activity was attributed to their production of bacteriocin, organic acids, and low-molecular-weight substances. Additionally of note was their resistance to several antibiotics; all four strains resisted oxacillin, and three out of four resisted vancomycin and streptomycin. The study concludes by suggesting the potential for these LAB strains to be considered probiotic candidates for application in the food industry post in-vivo evaluation.
A Network Pharmacology published in 2020 in the journal Nutrients found that Ganpu tea, derived from Pu-erh tea and the pericarp of Chachi, enhances antioxidant capacities and modulates gut microbiota beneficially more than Pu-erh tea alone. A thorough chemical analysis was conducted on hot-water extracts of Ganpu tea using ultra-high performance liquid chromatography and quadrupole-time-of-flight tandem mass spectrometry, which identified a total of 92 constituents. Considering the antioxidant properties of Ganpu tea, an experiment was designed and carried out where rats were fed with Ganpu tea over a long period. The same experiment was done using Pu-erh tea and the pericarp of Chachi separately, allowing for comparisons of antioxidant capacities between them and Ganpu tea. The results showed that Ganpu tea had a substantial impact on improving the activities of superoxide dismutase and glutathione peroxidase, both essential antioxidants, more than Pu-erh tea. This indicated a superior antioxidant capacity of Ganpu tea. Further, it significantly increased the abundance of specific gut bacteria, offering a suggestion of the potential benefits of Ganpu tea in human gut microbiota modulation. The results underscore the health benefits of Ganpu tea in enhancing antioxidant activities and promoting beneficial gut microbiota.
