Supports Intestinal HealthThe preB in Best Fermented Superfoods is derived from health-promoting macrobiotic source foods including fruits, vegetables, legumes, grains, nuts, seeds, and spices. In addition to nutrients, these source foods contain countless natural phytochemicals and bioactive compounds, many of which are considered as contributing to human health. Fermentation further endows these foods with yet more potential for health benefits. Cabbage, one of the source foods in Best Fermented Superfoods, contains compounds called glucosinolates. During fermentation, breakdown products of glucosinolates form, most notably isothiocyanates, indole-3-carbinol, and sulforaphane. These newly formed fermentation compounds have potential health benefits; for example, glucosinolate breakdown products are believed to enhance the synthesis of detoxification enzymes. Numerous studies conducted on kimchi—a popular Korean preparation of fermented vegetables—reveal many potential benefits, such as increased activities of liver enzymes that help rid the body of foreign compounds. Research on preB, the active ingredient in Best Fermented Superfoods The impact of preB administration in humans has been investigated in Japan, Brazil, China, and the United States. A common finding in all four trials was an excellent safety profile for preB. In a randomized, double-blind study of 75 subjects given either preB or placebo for 6 weeks, 43 metabolic parameters were assessed before and after the supplementation. No adverse events were reported in either group. An interesting find was a statistically significant difference in the Erythrocyte Sedimentation Rate (ESR) between groups. The ESR measurement was surmised to be a signal that preB promoted a decline in non-specific immune system overreaction. In a Japanese pilot study of 30 healthy subjects given high-dose preB supplements for 90 days, changes in several species of intestinal bacterial flora were documented.
