Hypoglycemic Properties of Leccinum scabrum Extracts—An In Vitro Study on α-Glucosidase and α-Amylase Inhibition and Metabolic Profile Determination

Researchers tested birch bolete mushrooms (Leccinum scabrum) for diabetes-fighting properties. They found that extracts from this edible mushroom were exceptionally effective at blocking enzymes that break down carbohydrates, potentially helping control blood sugar levels. The study identified key beneficial compounds including healthy fats and plant alkaloids, suggesting the mushroom could become a functional food or dietary supplement for managing type-2 diabetes.

Suitability of maize crop residue fermented by Pleurotus ostreatus as feed for edible crickets: growth performance, micronutrient content, and iron bioavailability

Researchers tested whether crickets could be raised on inexpensive mushroom-fermented corn stalks as an alternative to costly grain feeds. While the fermented stalks made iron more absorbable by the human body, the crickets actually grew worse on this feed compared to unfermented stalks. The study suggests that combining mushroom and cricket farming, while theoretically appealing for sustainability, may not work well in practice due to poor cricket survival and growth on spent mushroom substrate.

Individual and Combined Effect of Zinc-L-Selenomethionine Complex with Mannan-Oligosaccharide on Growth Performance, Carcass Characteristics, Gut Development and Immune Response in Broilers

This study tested whether combining organic selenium and a prebiotic from yeast could improve broiler chicken health without using antibiotics. The researchers fed different groups of chickens either selenium alone, the prebiotic alone, or combinations of both at different levels over 35 days. They found that the combination of higher selenium levels with the prebiotic worked best for improving meat quality, immune system strength and gut health, making it a promising natural alternative to growth-promoting antibiotics in chicken farming.

Acceptability of Vegetable Fortified Ugali in Sub-Saharan Africa

Researchers tested adding freeze-dried vegetables to ugali, a staple corn porridge eaten by millions in Africa, to boost nutrition. Chinese onion stalk was the clear winner—it actually tasted better than plain ugali and provided extra vitamins and fiber. Carrot and bok choy also worked well, making nutrient-enriched ugali a practical solution for improving health in areas where nutritious side dishes are hard to find.

The effect of chitosan supplementation on liver function, hepatic steatosis predictors, and metabolic indicators in adults with non-alcoholic fatty liver disease: a randomized, double-blinded, placebo-controlled, clinical trial

This study tested whether taking chitosan supplements (a type of dietary fiber) helps people with fatty liver disease. Over 8 weeks, participants taking chitosan along with a calorie-reduced diet lost more weight, reduced their waist size, and showed improvement in liver enzyme levels compared to those taking placebo. However, the supplement did not significantly improve cholesterol, blood sugar, or other metabolic markers at the dose tested.
