Cottage cheese is a promising matrix for delivering probiotic microorganisms due to its buffering capacity, high moisture content, and consumer acceptance. In this study, a probiotic cottage cheese incorporating Lactobacillus acidophilus LA-5 was developed and evaluated against a control formulation and commercial products. Physicochemical properties, probiotic viability, acidification kinetics, and sensory acceptance were assessed during refrigerated storage. The formulatio [...]

The unbalanced nutrient density and low microbiological quality of many complementary foods are still the primary causes of infant malnutrition in poorer countries. In this study, complementary food was produced using blends of grain amaranth, African yam bean, and carrot flour. The resultant complementary food was analysed for proximate, mineral, antinutrients, antioxidant compositions, vitamin C, beta-carotene, microbial properties, and sensory evaluations. Principal component analysis was als [...]

Berberine is an alkaloid chemical found in plants, including Berberidaceae, Coptis rhizomes, and Hydrastis canadensis. Berberine has been shown to improve insulin sensitivity, promote adipocyte loss, and is associated with higher levels of skeletal muscle protein synthesis. The purpose of this study was to examine berberine’s dose-dependent effects on C2C12 myoblast proliferation and 3T3L1 adipocyte differentiation. Cells were grown [...]

Dietary and lifestyle choices have considerable effects on skin health, which reflects overall well-being. Nutrition is now a key component in the management and prevention of skin-related issues due to the increasing incidence of dermatological disorders and the growing demand for anti-aging remedies. This review examines the complex relationship between nutrition, diet, and skin aging, with a focus on the functions of probiotics, vitamins, minerals, essential fatty acids, and antioxidants. Evi [...]

Excess dietary calories relative to energy expenditure lead to increased body weight, a problem now widely described as an epidemic because of its association with numerous disease states. Although free digestible sugars are to the most extent absorbed relatively easily from foods in healthy individuals, this is not the case for starches; where the physico-chemical properties control the rate and extent of enzymatic hydrolysis in the small intestine. Thus, even when the quantity of starch in a f [...]

Thyroid disorders are an actual global health concern requiring diverse therapeutic strategies. Potentilla alba (P. alba), commonly known as White cinquefoil, has been used in folk medicine for its rich composition of microelements and pharmacologically essential phytocompounds. It has now also gained recognition in evidence-based medicine for its potential to treat thyroid dysfunction, particularly hypothyroidism and nodular goiter. However, the complic [...]

Climate change, biodiversity loss, and malnutrition are interconnected global challenges that increasingly threaten food security, healthy diets, and environmental sustainability. Current dietary patterns characterized by high consumption of ultra-processed foods have negative environmental impacts, including increased greenhouse gas emissions, water and land use, malnutrition, and biodiversity loss. Sustainable and healthy diets that emphasize plant-based foods, minimize food waste, and promote [...]

Risperidone is a commonly used antipsychotic drug in juveniles, but with serious metabolic side-effects. Previous evidence suggests that exercise mitigates risperidone-induced hypertriglyceridemia and adipose accumulation, yet the underlying hepatic mechanisms remain unclear. In this study, female juvenile rats were randomly assigned to four groups (n = 8/group): Vehicle + Sedentary, Risperidone (0.9 mg/kg, twice daily) + Sedentary, Vehicle + Exercise (3-hour voluntary access to a running wheel/ [...]

Despite industrial hemp (Cannabis sativa L.) being long recognized for its diverse bioactive phytochemicals, most scientific studies have predominantly focused on aerial tissues, leaving the roots relatively underexplored. This review provides a comprehensive overview of the phytochemical architecture, biological functionalities, and nutraceutical prospects of hemp root extracts. Characterized by a unique metabolic profile featuring pentacyclic triterpenoids, phytosterols, s [...]
