This study was designed as a 6 month intervention study. The main objective was to evaluate the effect of an energy deficit (10%, 20%, and 25%-groups D10, D20, and D25, respectively) on the rate of weight loss and waist and hip circumferences.

Edible insect protein concentrates: Optimized salt-assisted extraction methods evaluation.

This study explores the extraction of proteins from edible insects such as Tenebrio molitor, Acheta domesticus, and Locusta migratoria using alkaline extraction and acid precipitation (AEAP) as a control method and evaluates the influence of salting-in (NaCl-assisted), salting-out ((NH₄)₂SO₄), and combined salting-in/out techniques on the resulting protein quality and functional properties. We hypothesized that salt-assisted methods would enhance protein extraction efficiency and functionality compared to AEAP. Molecular size distribution analysis confirmed that the salting-out method preferentially aggregated smaller proteins (<30 kDa).

Advancing protein hydrolysis and phytosterol encapsulation: Emerging trends and innovations in protein-based microencapsulation techniques - A comprehensive review.

Phytosterols represent a diverse and complex category of lipophilic bioactive compounds, exhibiting excellent pro-healthy properties. However, their consumption in daily diets is insufficient, and their application in food production is hindered by challenges such as low water solubility, high reactivity, and rapid degradation. The adoption of different protein or their structural modification as hydrolysates as wall material into microencapsulation techniques can be associated with improved solubility, enhanced bioaccessibility, increased bioavailability, and an extension of shelf life.

Sulphotransferase-mediated toxification of chemicals in mouse models: effect of knockout or humanisation of SULT genes.

Cytosolic sulphotransferase (SULT) enzymes catalyse reactions involved in xenobiotic elimination and hormone regulation. However, SULTs can also generate electrophilic reactive intermediates from certain substrates, including the activation of carcinogens. Here, we review toxicological studies of mouse strains with SULT status altered by genetic modification.

Palmitic acid and eicosapentaenoic acid supplementation in 3T3 adipocytes: impact on lipid storage and oxidative stress.

Objectives: Obesity is a worldwide public health problem, predisposing individuals to serious cardiovascular and metabolic complications such as type 2 diabetes mellitus. White adipose tissue serves as an important regulator of energy balance, and its expansion in obesity can trigger inflammatory reactions and oxidative stress, which can also lead to insulin resistance. Adipocytes, with a key role in regulating metabolic homeostasis, respond to increased calorie intake and altered fatty acid composition with hypertrophy or hyperplasia.

The contribution of mitochondria-associated ER membranes to cholesterol homeostasis.

Cellular demands for cholesterol are met by a balance between its biosynthesis in the endoplasmic reticulum (ER) and its uptake from lipoproteins. Cholesterol levels in intracellular membranes form a gradient maintained by a complex network of mechanisms including the control of the expression, compartmentalization and allosteric modulation of the enzymes that balance endogenous and exogenous sources of cholesterol. Low-density lipoproteins (LDLs) are internalized and delivered to lysosomal compartments to release their cholesterol content, which is then distributed within cellular membranes.

A New LC-MS/MS-Based Method for the Simultaneous Detection of α-Tocopherol and Its Long-Chain Metabolites in Plasma Samples Using Stable Isotope Dilution Analysis.

Our study presented a novel LC-MS/MS method for the simultaneous quantification of α-tocopherol (α-TOH) and its phase II metabolites, α-13'-COOH and α-13'-OH, in human serum using deuterium-labeled internal standards (d-α-TOH, d-α-13'-COOH, d-α-13'-OH). The method addresses the analytical challenge posed by the significantly different concentration ranges of α-TOH (µmol/L) and its metabolites (nmol/L). Previous methods quantified these analytes separately, which caused an increase in workflow complexity.

Consumption of Sugar-Sweetened Beverages by Polish Young Adults: A Preliminary Study on the Importance of Sugar Tax Familiarity and Health Effects.

Consumption of sugar-sweetened beverages (SSBs) contributes to the risk of developing overweight and obesity in children and adults. Thus, reducing free sugar is a globally recognized public health priority. The implementation of a sugar tax is one way of achieving this goal.

The Effect of Cooking and Cooling Chickpea Pasta on Resistant Starch Content, Glycemic Response, and Glycemic Index in Healthy Adults.

Legume seeds, such as chickpeas, are a rich source of resistant starch (RS) and have a low glycemic index (GI). The aim of this study was to evaluate the effect of cooking and cooling chickpea pasta on the RS content, glycemic response, and GI in healthy subjects. Twelve healthy subjects of both sexes, aged 18-65 years, participated in this study.

DEP-1 is a brain insulin receptor phosphatase that prevents the simultaneous activation of counteracting metabolic pathways.

A healthy metabolism relies on precise regulation of anabolic and catabolic pathways. While insulin deficiency impairs anabolism, insulin resistance in obesity causes metabolic dysfunction, especially via altered brain insulin receptor (IR) activity. Density-enhanced phosphatase 1 (DEP-1) negatively modulates the IR in peripheral tissues.

Cutaneous Carbonyl Stress Is Associated With Nerve Dysfunction in Recent-Onset Type 2 Diabetes.

Objective: Endogenous carbonyl stress leads to the formation of advanced glycation end products (AGEs). AGEs represent a potential target to prevent or treat diabetic sensorimotor polyneuropathy (DSPN). The current study aimed to characterize cutaneous carbonyl stress, oxidative stress, immune cells, and endothelial cell damage in early type 2 diabetes compared with normal glucose tolerance (NGT) using novel cutaneous biomarkers.

Increase in PUFA and protein, and decrease in carbohydrate intake improves liver fat in 12 months and the role of weight loss as a mediator: A randomized controlled trial.

Background & Aims: Recently, a beneficial effect of high intake of unsaturated fatty acids (UFA) and protein on intrahepatic lipids (IHL) was demonstrated over 12 months within a randomized controlled trial (the NutriAct trial). We now aimed to explore the specific macronutrient components driving this IHL improvement within this trial in middle-aged and elderly subjects (50-80 y) at risk for age-related diseases.

Methods: The NutriAct trial (n = 502) analyzed the effect of a high-protein and high-UFA diet on age related diseases including fatty liver disease.

Healthy food diversity and the risk of major chronic diseases in the EPIC-Potsdam study.

Practicing a diverse diet may reduce chronic disease risk, but clear evidence is scarce and previous diet diversity measures rarely captured diet quality. We investigated the effect of the Healthy Food Diversity (HFD)-Index on incident type 2 diabetes (T2D), myocardial infarction (MI) and stroke among a middle-aged German population. The EPIC-Potsdam study recruited 27,548 participants from 1994 to 1998.

Metabolic scaling, energy allocation tradeoffs, and the evolution of humans' unique metabolism.

All organisms use limited energy to grow, survive, and reproduce, necessitating energy allocation tradeoffs, but there is debate over how selection impacted metabolic budgets and tradeoffs in primates, including humans. Here, we develop a method to compare metabolic rates as quotients of observed relative to expected values for mammals corrected for size, body composition, environmental temperature, and phylogenetic relatedness. Contrary to previous analyses, these quotients reveal that nonhuman primates have total metabolic rates expected for similar-sized mammals in similar environments.

Nutritional quality of diet characterized by the Nutri-Score profiling system and cardiovascular disease risk: a prospective study in 7 European countries.

Background: Nutri-Score is a scientifically validated 5-color front-of-pack nutrition label reflecting the nutrient profile of foods. It has been implemented in several European countries on a voluntary basis, pending the revision of the European labeling regulation. Hence, scientific evidence is needed regarding the ability of the nutrient profile underlying the Nutri-Score (uNS-NPS, 2023-updated version) to characterize healthier foods.
