Abstract Objectives Approximately 1.4 million people suffer from inflammatory bowel disease, which is a major risk factor for developing colitis associated colorectal cancer (CAC). Dietary interventions with the goal to reduce colon inflammation and encourage gut microbiome homeostasis may be a strategy to reduce the risk of CAC. The antioxidants and anti-inflammatory compounds present in black raspberries (BRB) have demonstrated protective effects in the colon epithelium and may alter the composition of the gut microbiome. Previously, we showed that dietary supplementation with black raspberries significantly suppressed colitis and colon tumorigenesis promoted by the consumption of a Western type diet in mice. The goal of this study was to compare the efficacy of dietary intervention with whole, freeze-dried black raspberries on colitis and colon tumorigenesis in mice consuming either a standard diet or a Western type diet that emulates typical U.S. nutrient intakes. Methods C57BL/6 J male and female mice were fed a standard diet (AIN93G) or the total Western diet (TWD) supplemented with 0 to 10% (w/w) black raspberry powder for a total of 16 weeks. All mice were dosed with axozymethane and provided 1% dextran sodium sulfate in drinking water for 10 days to promote colonic inflammation and tumorigenesis. Results As previously observed, mice fed TWD experienced more pronounced symptoms of colitis with a 40% increase in the disease activity index (DAI) score. Preliminary analyses suggest that dietary supplementation with 10% BRB suppressed the DAI score in mice fed TWD such that the colitis symptoms in these mice were not apparently different compared to the AIN93G-fed controls. However, addition of 10% BRB did not appear to provide a benefit to mice fed the AIN basal diet. Composition of the fecal microbiome over the course of disease development will be determined by standard 16S rRNA sequencing, and assessment of tumor outcome is ongoing. Conclusions Consumption of a Western type diet increased symptoms of colitis, whereas dietary supplementation with 10% BRB appeared to ameliorate TWD-enhanced colitis in mice.

Nutritional Imbalance

One of the most prominent concerns that has arisen from global events such as the Coronavirus Disease 2019 (COVID-19) pandemic is how the immune system might be enhanced to provide greater protection against malignant conditions and diseases. Dietary modification is one of the major fields of research, with special focus on how diet interacts with immunity through impacts on factors such as the gut microbiome, inflammation, and nutritional imbalance. This review focuses on current research regarding the use of bioactives derived from berries as a dietary supplement to improve immunity, with discussions of relevant clinical studies. Major bioactive, metabolic compounds of focus- flavonoids, anthocyanins, alkaloids, dietary fiber, and stilbenes- have demonstrated biochemical merits in modulating immunity. In addition, blueberries, goji berries, black raspberries, and cranberries, which have been extensively researched and recently gained interest for their effects on the immune system in animal and cell models, may also hold promise in providing similar benefits to humans, though the precise immunological effects have yet to be clearly determined. Overall, the field of berry research as it relates to diet and immunity shows potential, but more clinical studies will be necessary for a full understanding of the mechanisms of berry immunomodulation.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Flavonoids are naturally occurring plant polyphenols found universally in all fruits, vegetables and medicinal plants. They have emerged as a promising candidate in the formulation of treatment strategies for various neurodegenerative disorders. The use of flavonoid rich plant extracts and food in dietary supplementation have shown favourable outcomes. The present review describes the types, properties and metabolism of flavonoids. Neuroprotective role of various flavonoids and the possible mechanism of action in the brain against the neurodegeneration have been described in detail with special emphasis on the tangeritin.
