We determined the effects of continuous access to drinking of water with a vinegar-based multi-micronutrient (VMm) supplement containing rice and fruit vinegars, vitamins, organic acids and sugars during gestation, lactation, and early adulthood in rats. Pregnant rats were provided with reverse-osmosis water or VMm water from the start of pregnancy through the time of weaning. Weaned pups consumed the same drinking water for 3–12 additional weeks. We examined fecal metabolite and microbial profiles, and other physiological parameters. Body weights were less in rats that drank VMm water. Thirty fecal metabolites involved in amino acid and dipeptide metabolism were significantly altered in VMm-supplemented rats. Analysis of microbial 16S rRNA showed enrichment of bacteria in the family S24–7 in VMm-supplemented rats, and one in Ruminococcaceae in controls. Our data show that a VMm-containing beverage can alter growth, and gut metabolism and microbial community. Future work to correlate these parameters is warranted.
Background: Some natural substances may affect the expression of microRNAs (miRNAs) in humans. However, it is unclear whether this effect can be induced by the ingestion of whole foods containing these natural substances. Objective: We investigated whether ingestion of the whole food FFC ® Pairogen affects the expression of miRNAs in humans. Design: This was a pilot study and part of a randomized controlled trial. Four subjects ingested the test material daily for 8 weeks (three times 180 ml bottles a day, morning, noon and evening; a total of 540 ml per day). The study did not include control subjects. Results: Several miRNAs showed differential expression. The expression of two miRNAs, hsa-let-7c and hsa-miR-92a-2-5p, changed in three of the four subjects, who had lower concentration of serum total antioxidant status. The expression of hsa-let-7c increased and that of hsa-miR-92a-2-5p decreased. Conclusions: The expression of hsa-let-7c and hsa-miR-92a-2-5p has been linked with lung cancer manifestation. The increased expression of hsa-let-7c and the decreased expression of hsa-miR-92a-2-5p suggest possible oncogene suppressive functions of these miRNAs. The ingestion of FFC ® Pairogen may have a positive effect on cancer prevention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
