β-Carotene prevents weaning-induced intestinal inflammation by modulating gut microbiota in piglets

Ruonan Li et al.

Summary: The study revealed that beta-carotene can alleviate weaning-induced intestinal inflammation in piglets by modulating gut microbiota, and Prevotella may be a potential target for this alleviation.

Biofortified orange corn increases xanthophyll density and yolk pigmentation in egg yolks from laying hens

Darwin Ortiz et al.

Summary: The study found that feeding high carotenoid Orange Corn significantly increased the color and carotenoid concentration of egg yolks. Yolks from hens fed with the Orange Corn diet had higher levels compared to those fed with yellow or white corn, and were superior to commercial egg brands, suggesting that using high carotenoid Orange Corn in poultry diets can enhance xanthophyll density in eggs.

Orange corn diets associated with lower severity of footpad dermatitis in broilers

M. E. Abraham et al.

Summary: Footpad dermatitis, damage and inflammation of the plantar surface, is concerning for poultry welfare and production. This study found that exposure to wet litter was the main factor causing FPD. Compared to yellow and white corn, orange corn was associated with improved bird growth and reduced severity of footpad dermatitis, particularly at later time points.

Mechanistic aspects of carotenoid health benefits - where are we now?

Torsten Bohn et al.

Summary: Intake and tissue levels of carotenoids are associated with reduced risk of chronic diseases, but intervention trials with isolated carotenoid supplements have mostly failed to confirm health benefits. Basic mechanisms include antioxidant actions and activation of nuclear hormone receptor pathways, with potential different mechanisms for different diseases.

Dietary Fiber Hierarchical Specificity: the Missing Link for Predictable and Strong Shifts in Gut Bacterial Communities

Thaisa M. Cantu-Jungles et al.

Summary: The study suggests that high-specificity dietary fibers result in more similar responses in gut microbiota, while low-specificity dietary fibers lead to different responses among subjects. High-specificity fibers can promote targeted and predictable microbial shifts in the gut.
