Article Synopsis
  • A high-fat and high-fructose diet can alter gut microbiota and lead to metabolic changes, while chia oil contains beneficial alpha-linolenic acid with potential gut health benefits.
  • In an experiment with rats, those on a high-fat diet supplemented with chia oil showed increased levels of immunoglobulin A and short-chain fatty acids, indicating improved intestinal health.
  • Despite the benefits of chia oil, the overall diversity of gut microbiota remained unchanged, but certain beneficial bacterial genera were more prevalent in rats consuming chia oil compared to standard diets.

The demand for organic vegetables is increasing worldwide, which has led to the growth of organic agriculture. However, information on chemical composition and antioxidant activity in vegetables grown organically under controlled conditions remains uncertain. For this study, 3 vegetables widely consumed in Brazil were cultivated in controlled organic and conventional cultivation systems: lettuce, coriander and tomato.

Phenolic compounds can act as a substrate for colonic resident microbiota. Once the metabolites are absorbed and distributed throughout the body, they can have diverse effects on the gut. The objective of this study was to evaluate the effects of the intra-amniotic administration of a chia phenolic extract on intestinal inflammation, intestinal barrier, brush border membrane functionality, intestinal microbiota, and morphology in vivo ( model).

Chia is a functional food because of its positive impact on reducing the risk of metabolic diseases. These benefits are due to its nutritional composition as a source of dietary fiber and bioactive compounds. In our previous study, chia consumption increased the richness of the microbiota and the production of short chain fatty acids (SCFAs) when consumed by male Wistar rats, so, the objective of this study was to assess the effects of the consumption of chia with a high fat diet on gut health in female Wistar rats.

Article Synopsis
  • Millet is a nutritious cereal rich in dietary fiber, protein, and bioactive compounds that can enhance health.
  • The study tested the effects of non-germinated and germinated whole millet flour on protein quality and gut health in rats, revealing that germinated millet led to better protein efficiency and lower levels of harmful substances in the bloodstream.
  • Overall, the findings suggest that consuming millet, especially in its germinated form, may improve health and could serve as a beneficial addition to human diets for better nutritional diversity.

Cashew nuts are rich in dietary fibers, monounsaturated fatty acids, carotenoids, tocopherols, flavonoids, catechins, amino acids, and minerals that offer benefits for health. However, the knowledge of its effect on gut health is lacking. In this way, cashew nut soluble extract (CNSE) was assessed in vivo via intra-amniotic administration in intestinal brush border membrane (BBM) morphology, functionality, and gut microbiota.

Article Synopsis
  • Chia protein is rich in bioactive peptides, and probiotics help maintain gut health; this study looked at how administering these substances into fertile broiler eggs affects their intestinal health.
  • Five experimental groups were created, including non-injected controls and groups receiving either chia protein, probiotics, or both, with administration occurring on day 17 of incubation.
  • Results showed that both chia protein and probiotics led to lower inflammation and enhanced intestinal barrier function, positively impacting the gut structure and overall health of the hatchlings.

The Western diet can negatively affect the gut microbiota and is associated with metabolic disorders. Kombucha, a tea fermented by a symbiotic culture of bacteria and yeast (SCOBY), is known for its bioactive properties and has become popular in the last years. In this study, we evaluated the effects of regular kombucha consumption on the gut microbiota and on outcomes related to the intestinal health of Wistar rats fed a high-fat high-fructose diet.

Purpose: The present study aimed to evaluate the effect of chia flour associated with a high fat diet on intestinal health in female ovariectomized Wistar rats.

Methods: The study was conducted with 32 adult female ovariectomized Wistar rats, which were separated into four groups: standard diet (ST), standard diet with chia (STC), high fat diet (HF) and high fat diet with chia (HFC) for 18 weeks. Cecum content pH, short chain fatty acid content, brush border membrane functionality and morphology and the gut microbiota were evaluated.

Macauba () has aroused interest in the food industry due to the high nutritional value of its fruits. This study aimed to evaluate the protein quality and influence on biochemical markers, short chain fatty acids content, intestinal morphology, and intestinal functionality in rats of macauba kernel. Male young rats were divided into three groups ( = 8) that received a control diet (casein), and two test diets (M30: 30% semi-defatted macauba kernel flour or M50: 50% semi-defatted macauba kernel flour) for 29 days.

Aim: The present study aimed to investigate the effect of dry heated whole sorghum BRS 305 hybrid flour on the gut microbiota modulation and gut health of rats fed with a high-fat high-fructose diet (HFHF).

Methods: In phase I (8 weeks), 45-50 days, male Wistar rats, were separated into the AIN93-M group (n = 10; fed with normal diet) and HFHF group (n = 20; fed with diet rich in saturated and simple carbohydrate). In phase II (10 weeks), we maintained the AIN-93-M group, and the HFHF group was divided into the HFHF group (n = 10) and HFHF plus sorghum flour group (n = 10).

Background: People living with HIV (PLHIV) present impaired muscle metaboreflex, which may lead to exercise intolerance and increased cardiovascular risk. The muscle metaboreflex adaptations to exercise training in these patients are unknown. The present study aims to investigate the effects of a supervised multimodal exercise training on hemodynamic and autonomic responses to muscle metaboreflex activation in PLHIV.

The intra-amniotic administration approach has been used to evaluate the effects of plant origin prebiotics on intestinal health and on brush border membrane functionality and morphology. Prebiotics are fermentable dietary fibers, which can positively affect the host by selectively stimulating the growth and activity of colon bacteria, thus improving intestinal health. The consumption of prebiotics increases digestive tract motility, which leads to hyperplasia and/or hypertrophy of intestinal cells, increasing nutrient digestive and absorptive surface area.

The reduction in estrogen levels is associated with the increased risk factors for cardiovascular disease development. The present study aimed to evaluate the effect of chia consumption in a standard diet (SD) or high fat diet (HFD) on ovariectomized (OVX) and non-ovariectomized (SHAM) rats, in relation to biometric measurements, oxidative stress, mineral content and ATPase enzymes in the heart. The study was conducted with 80 female Wistar rats, which received a SD or HFD for 18 weeks.
