Summary: This study investigates the association between energy extraction from the diet and intestinal transit time and microbial community structure in overweight adults. Contrary to expectations, individuals with longer intestinal transit time extracted more energy from their diet. Different enterotypes were also associated with variations in energy extraction, with individuals in the Ruminococcaceae enterotype having higher energy extraction than those in the Bacteroides enterotype.

Summary: The study found that dietary fiber supplementation can affect gut microbiota and blood lipid regulation, but not all individuals have a positive response to dietary fiber treatment, and some may lack the ability to maintain a stable SCFA-producing bacterial diversity and composition.

Summary: Edible flowers are popular among researchers, nutritionists, and chefs all over the world not only for their aesthetic value and taste enhancement, but also for their valuable nutrient content. This study aimed to determine the dietary fiber and total protein content in selected edible flowers, comparing the nutritional content of petals from the Oleaceae and Asteraceae families, as well as herbaceous and woody plants. The results showed that edible flowers are a good source of dietary fiber and plant protein, with high levels found in the Asteraceae family. These findings have important implications for the daily diet of athletes and the prebiotic function of gut bacteria.

Summary: This article provides an updated overview of the evidence, factors, and possible mechanisms of the impacts of soluble dietary fibre (SDF) on starch digestibility. The relationship between SDF and starch digestibility is found to be dependent on the nature of SDF and starch. The mechanisms by which SDF affects starch digestibility include modifying the structure of starch or food, increasing the viscosity of intestinal contents, decreasing the activities of amylolytic enzymes, and regulating the levels of hormones or other metabolites related to starch digestion. Future efforts should focus on gaining a full understanding of the underlying mechanism and obtaining valuable data for designing healthy foods.

Summary: This study aimed to investigate the additive effects of a combination of energy restriction (ER) and four dietary supplements on changes in anthropometric and biochemical parameters in overweight or obese participants. The results showed that dietary fibre supplements plus ER significantly reduced body weight, BMI, fat mass, and visceral fat, and improved lipid profile and inflammation. A fibre supplement containing glucomannan, inulin, psyllium, and apple fibre was the most effective at reducing BMI, body weight, and CRP.

Summary: In this study, the impact of resistant starch (RS) on meat duck intestine and its resident microbiota was investigated. The results showed that dietary RS improved intestinal morphology and barrier function in meat ducks, as evidenced by enhanced expression of tight junction proteins and Mucin-2 gene. RS administration also led to changes in the gut microbiome and metabolome, with increased proportions of Firmicutes and butyrate-producing bacteria, as well as alterations in amino acid and lipid metabolism. These findings provide valuable insights into the mechanism by which RS improves the gut system of ducks.

Summary: This study optimized the processing conditions of twin-screw extrusion cooking to increase soluble dietary fiber in lupin seed coat while retaining high levels of polyphenols. The extrusion cooking had minimal effects on the bioavailability of minerals and polyphenols. The extrusion cooked lupin seed coat could be a natural antioxidant dietary fiber source for human consumption.

Summary: Dietary fiber in wheat bran can act as a carrier of bound polyphenols in the gut, promoting gut health through their prebiotic activity and strong radical scavenging activity. Colonic fermentation of soluble dietary fiber significantly increases the bioaccessibility of bound polyphenols and stimulates the growth of beneficial bacteria while reducing the abundance of harmful bacteria.

Summary: This study investigated whether enzymes are essential in analyzing insoluble, soluble, and total dietary fiber (IDF, SDF and TDF) contents in dry fruits with low starch and protein contents. The results showed agreement between both enzymatic and non-enzymatic methods in measuring IDF, SDF, and TDF values in date fruits. The study confirmed that dates are a rich source of dietary fiber and the non-enzymatic technique is a viable substitute for enzymatic analysis of dietary fiber in dry fruits.

Summary: This study aimed to assess the impact of a 6-week intake of a probiotic product on an oxidative stress model of physical exercise in male cyclists. Results showed significant reductions in urinary 8-OHdG, serum MDA, and Ox-LDL in the probiotic group compared to placebo, suggesting an antioxidant effect on oxidative stress mechanisms in healthy subjects. Serum GPx did not increase in the probiotic group, while it significantly increased in the placebo group.

Summary: The study investigated the effects of high-dose beta-alanine supplementation on the time-trial performance of world tour cyclists during overreaching training. Results showed that beta-alanine improved mean power, distance traveled, and total work compared to the placebo, with higher levels of lactate and anion gap in the beta-alanine group. High doses of beta-alanine were well tolerated and could help attenuate performance losses in cyclists.

Summary: This study compared the tolerability of oral supplementation with AB-Fortis (R) and conventional ferrous sulfate (FS) in healthy premenopausal women, and found that AB-Fortis (R) had significantly better tolerability than FS. The better tolerability of AB-Fortis (R) was further confirmed when compared to a real-life setting. Overall, the administration of both study products was safe with no serious or significant adverse events reported.

Summary: This systematic review and meta-analysis examined the effects of dry needling alone or in combination with exercise therapy for reducing pain and disability in people with subacromial pain syndrome. The results showed that dry needling alone or combined with exercise therapy may result in a slight reduction in pain in the short-term and mid-term. However, the evidence about the effect of this therapy on disability in the short- or mid-term is very uncertain.

Summary: This study compared the impact of two community-based physical activity programs on health-related quality of life and physical condition in individuals with cardiovascular risk factors. The results showed that a 6-month individualized training program had a more favorable effect on physical functioning, mental health, energy/vitality, and general health compared to a 3-month non-individualized program. The participants in the 6-month program also showed greater improvements in VO2 max and flexibility.

Summary: Metabolic syndrome is linked to increased risks of cardiovascular disease and type 2 diabetes, further exacerbated by a sedentary lifestyle and situations like the COVID-19 pandemic. Recent studies suggest that consumption of polyphenol-rich fruits and vegetables has a protective effect in reducing cardiovascular risk. Hibiscus sabdariffa (HS) in combination with other plant extracts has been gaining attention for its potential in treating metabolic syndrome. A systematic review and meta-analysis of randomized clinical trials were conducted to examine the effects of HS with other plant extracts on metabolic syndrome prevention, revealing improvements in anthropometric parameters, blood pressure, and lipid profile.
