Effects of fiber sources with different solubilities on the growth performance, nutrient metabolism, antioxidant, immune capacity and intestinal health of meat geese

This study examined how different types of dietary fiber affect the health and growth of meat geese. Researchers compared three fiber sources with different levels of solubility: wheat bran (highly soluble), alfalfa meal (moderately soluble), and bamboo meal (low solubility). They found that the highly soluble fiber source improved growth, enhanced immune and antioxidant functions in the intestines, and promoted beneficial bacteria, making it the best choice for geese farming.

Fruit and Vegetable Processing Waste as Potential Raw Material for Food Enrichment With Dietary Fiber

This study examined the fiber content of leftover materials from processing fruits and vegetables, finding that pomace (processing waste) is an excellent source of dietary fiber. Chokeberries and blackcurrants were found to have particularly high fiber levels, while apples and carrots were rich in soluble fiber types. These waste products can be used to create nutritious fiber-enriched foods and supplements, providing both environmental benefits by reducing waste and health benefits through increased dietary fiber consumption.

Anti-Hyperlipidemic and Anti-Atherogenic Effect of Citrus Peel Pectin Against Cholesterol and Cholic Acid Induced Hyperlipidemia in Sprague Dawley Rats

Researchers tested whether pectin extracted from citrus peels could help treat high cholesterol and fat levels in the blood using rats. When rats were given different amounts of citrus peel pectin mixed into their food, their cholesterol and triglyceride levels decreased significantly while their good cholesterol (HDL) increased. The treatment also protected their heart, liver, and kidney tissues from damage. This suggests citrus peel pectin, usually thrown away by juice companies, could become a useful and natural remedy for managing high cholesterol.

Effect of soluble dietary fiber from corn bran on pasting, retrogradation, and digestion characteristics of corn starch

Researchers found that adding a special fiber derived from corn bran to corn starch significantly improves its properties for food production. The fiber helps prevent the starch from hardening over time, reduces how quickly the body digests it (important for controlling blood sugar), and improves texture and water retention. This discovery could help create healthier starch-based foods and better products for people with swallowing difficulties.

Three Different Types of β-Glucans Enhance Cognition: The Role of the Gut-Brain Axis

Researchers tested three types of β-glucans—fiber compounds found in mushrooms, oats, and other foods—to see if they could improve memory in mice. All three types enhanced recognition memory and reduced brain inflammation, while only oat β-glucan significantly changed gut bacteria composition. The findings suggest that different β-glucans may help prevent cognitive decline through different mechanisms involving the gut-brain connection.
