Study on supplementary food with beneficial effects on the gut microbiota of infants

Relationship between Oat Consumption, Gut Microbiota Modulation, and Short-Chain Fatty Acid Synthesis: An Integrative Review

“…A randomized controlled trial reported a significant increase in Bifidobacterium and Akkermansia, as well as a reduction in the Sutterellaceae family when 80 g/d of oats were consumed as part of a normal diet for 45 days [59]. Other animal and in vitro studies reported an increase in Bifidobacterium, as well as other beneficial bacteria such as Lactobacillus, the Firmicutes phylum, and the Eubacteriaceae family [46,48,[51][52][53]56]. Kristek et al (2019) concluded that oat bran had a greater impact on the intestinal microbiota than supplementation with β-glucan or isolated polyphenols, suggesting the importance of food form [58].…”

“…In one study evaluating different ways to process oat bran, steamed oat bran increased SCFA production more than microwave and hot-air oven processing [ 55 ]. When compared with other grains and fibers, such as corn, millet, and oligosaccharides in infant fecal inoculum, oat seems to preferentially increase Lactobacillus and promote butyrate production, even though overall SCFA production is similar among the grains [ 56 ]. However, other studies with adult fecal inoculum have reported increases in acetate and propionate and a decrease in butyrate with oat bran treatment, as well as increases in Bifidobacterium [ 103 ].…”

2′-Fucosyllactose Promotes the Production of Short-Chain Fatty Acids and Improves Immune Function in Human-Microbiota-Associated Mice by Regulating Gut Microbiota

“…The concentrations of fecal SCFAs were detected using a Fuli 9720 gas chromatograph as previously described. 30 A 500 μL sample from the intestinal contents (200 mg) treated with the HALO-F100 stool treatment instrument was mixed with 100 μL of crotonic acid monophosphate solution. The sample was centrifuged at 8000 rpm for 3 min at 4 °C, and the Serum Immunization Analysis.…”
