The effective production of xylooligosaccharides (XOS) from wheat bran was investigated. Wheat bran contains rich hemicellulose which can be hydrolyzed by enzyme; the XOS were obtained by microwave assisted enzymatic hydrolysis. To improve the productivity of XOS, repeated microwave assisted enzymatic hydrolysis and activated carbon adsorption method was chosen to eliminate macromolecules in the XOS. On the basis of experimental data, an industrial XOS production process consisting of pretreatment, repeated microwave assisted enzymatic treatment and purification was designed. Using the designed process, 3.2g dry of purified XOS was produced from 50 g dry wheat bran powder.

Background/objectives: In response to concerns about high-fat and low-fiber diets, this study modified a traditional brownie recipe by replacing butter with plant-based ingredients, including sweet potatoes, red beans, beetroot, zucchini, pumpkin, lentils, and spinach. The goal was to increase vegetable consumption while identifying the best vegetable fat replacer using sensory and instrumental analyses.
Methods: Chemical analyses were conducted to measure dry matter, protein, fat, ash, and dietary fiber, alongside texture, color, and sensory evaluations.

To assess the associations between serum and dietary polyunsaturated fatty acids (PUFAs), as well as the inflammatory potential of diet measured by the Children's Dietary Inflammatory Index (C-DII), and recurrent respiratory infections (RRIs) in children. We enrolled 44 children aged 3-16 years with RRIs and 44 healthy controls. Dietary intake was assessed using a 7-day food record from which PUFA intake and C-DII were calculated.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a major contributor to liver-related morbidity, cardiovascular disease, and metabolic complications. Lifestyle interventions, including diet and exercise, are first line in treating MASLD. Dietary approaches such as the low-glycemic-index Mediterranean diet, the ketogenic diet, intermittent fasting, and high fiber diets have demonstrated potential in addressing the metabolic dysfunction underlying this condition.

Introduction Emerging evidence suggests an association between obesity and Functional Gastrointestinal Disorders (FGIDs). Childhood obesity and FGIDs share many common features, such as high prevalence in the pediatric population, risk factors related to diet and lifestyle, gut microbiota impairments, and psychological distress. This narrative review aims to summarize the main evidence regarding FGIDs in childhood obesity, with a specific focus on the role of diet and its impact on the microbiota.
