Article Abstract
The effects of Bifidobacterium fermentation on dietary fiber (DF) of prosomillet bran were studied. Firstly, optimal fermentation conditions for extracting soluble dietary fiber were determined through single factor tests and orthogonal experiments. The structural features were evaluated by means of scanning electron microscopy, X-ray diffraction, Fourier infrared spectroscopy, particle size analysis, thermogravimetric analysis, and monosaccharide content. The results showed that some the crystal structure changed from crystal to non-crystal, which was followed by the decrease of thermal stability. The DF's surface loosened and its particle size decreased after fermentation. Meanwhile, DF showed similar spectral characteristics before and after fermentation, but the monosaccharide composition changed. Furthermore, the physicochemical properties were investigated. The fermented DF exhibited higher water swelling capacity, water holding capacity, oil holding capacity. Finally, improvements in glucose adsorption capacity, cation exchange and antioxidant properties were observed. These results indicated that Bifidobacteria fermentation is beneficial to the modification of DF.

Background: A plant-focused, healthy dietary pattern, such as the Mediterranean diet enriched with dietary fiber, polyphenols, and polyunsaturated fats, is well known to positively influence the gut microbiota. Conversely, a processed diet high in saturated fats and sugars negatively impacts gut diversity, potentially leading to weight gain, insulin resistance, and chronic, low-grade inflammation. Despite this understanding, the mechanisms by which the Mediterranean diet impacts the gut microbiota and its associated health benefits remain unclear.

Background: Dietary fiber supports metabolic health via microbial fermentation, producing short-chain fatty acids (SCFAs). However, metabolic responses to fiber vary between individuals, potentially due to differences in gut microbiota composition. The Prevotella-to-Bacteroides (P/B) ratio has emerged as a potential biomarker for fiber responsiveness.

This study investigated the association between energy and macronutrient intake and bone health in 63 adolescents of both sexes who participated in volleyball, track and field, or swimming. Bone mineral content (BMC) and density (BMD) of the total body less head (TBLH), lumbar spine (L1-L4), and femoral neck were assessed using DXA. Bone geometry parameters, including cross-sectional area (CSA), cross-sectional moment of inertia (CSMI), and section modulus, were estimated.

Soluble dietary fibers (SDFs) are recognized for their health benefits through their fermentation and gut microbiota modulation. Previous studies focused on individual SDFs without sufficient structural information and a comparative analysis using different SDFs on microbiota composition and function is lacking. The present study aimed to determine key structural features of different SDFs, including soluble resistant starch (SRS), inulin (INU), four structurally diverse pectins (PS1 to PS4), one pectic derivative (PS5) and larch arabinogalactan (AG).
