fruit has attracted more and more attention due to its various pharmacological activities, which are rich in polysaccharides. This study investigated the saliva-gastrointestinal digestion and fecal fermentation behaviors of polysaccharides from fruit (CAP), as well as its impact on human gut microbiota. The results showed that CAP could be partially degraded during the gastrointestinal digestion. The FT-IR spectra of the digested CAP didn't change significantly, however, the morphological feature of SEM changed to disordered flocculent and rod-like structures. 16S rRNA sequencing analysis found that after fermentation, CAP could increase the relative abundances of beneficial bacteria including , and to produce short-chain fatty acids (SCFAs), while it can also reduce the abundances of harmful bacteria of , , and , suggesting that CAP could modulate the composition and abundance of gut microbiota. These results implied that CAP can be developed as a potential prebiotic in the future.

Context: Prebiotics are often added to infant formulas to mimic the benefits of oligosaccharides found in human milk.
Objective: This systematic review and meta-analysis evaluated the effects of prebiotic-supplemented cow's milk-based formula on the gut microbiota, gut environment, growth parameters, and safety and tolerance in infants ≤6 months old, compared with a standard formula or human milk comparator.
Data Sources: Searches were performed in the PubMed, Embase, Cochrane Central Register of Controlled Trials, and ProQuest Dissertations & Theses databases.
New approaches to secondary metabolite discovery from anaerobic gut microbes.

The animal gut microbiome is a complex system of diverse, predominantly anaerobic microbiota with secondary metabolite potential. These metabolites likely play roles in shaping microbial community membership and influencing animal host health. As such, novel secondary metabolites from gut microbes hold significant biotechnological and therapeutic interest.

Aerobic exercise (AE) has been shown to offer significant benefits for Alzheimer's disease (AD), potentially influencing the gut microbiota. However, the impact of changes in intestinal flora in early Alzheimer's disease induced by aerobic exercise on metabolic pathways and metabolites is not well understood. In this study, 3-month-old APP/PS1 and C57BL/6 mice were divided into two groups each: a control group (ADC for APP/PS1 and WTC for C57BL/6) and an aerobic exercise group (ADE for APP/PS1 and WTE for C57BL/6).

This study investigated the effect of oleogel consumption on lipid metabolism, gut microbiota and low-grade inflammation in rats fed with a high-fat diet. Male SD rats received either a control diet or high-fat diets for six weeks. The high-fat diets included a regular high-fat diet and high-fat diets in which lard was replaced with pure sunflower oil, un-gelled sunflower oil containing a dispersed gelator, or gelled sunflower oil with the gelator (oleogel).

Since the widespread usage of plastic materials and inadequate handling of plastic debris, nanoplastics (NPs) and microplastics (MPs) have become global hazards. Recent studies prove that NPs/MPs can induce various toxicities in organisms, with these adverse effects closely related to gut microbiota changes. This review thoroughly summarized the interactions between NPs/MPs and gut microbiota in various hosts, speculated on the potential factors affecting these interactions, and outlined the impacts on hosts' health caused by NPs/MPs exposure and gut microbiota dysbiosis.
