This review explores innovative approaches to acid whey valorization, emphasizing biotechnological methods, fermentation techniques, and advanced membrane filtration processes. Comparative analysis of sweet and acid whey compositions underscores specific challenges and advantages in acid whey utilization, various valorization strategies, such as membrane filtration and ultrafiltration, osmosis, enzymatic, and microbial processing, highlighting their effectiveness in ingredient recovery and product development.

The success of these functional products significantly depends on selecting appropriate probiotic strains, encapsulation materials, and innovative microencapsulation methods.

Palmitoylethanolamide (PEA), particularly in the Levagen+® formulation, has been investigated for its potential stress-modulating effects through its anti-inflammatory and neuroprotective properties. This study aimed to assess the effects of 6 weeks of Levagen+® PEA supplementation on physiological and subjective markers of stress in moderately stressed female university students.</p><p><strong>Methods: </strong>A double-blind, placebo-controlled crossover trial was conducted with 16 female participants who met the inclusion criteria based on the Perceived Stress Scale (PSS).

T is mainly synthesized through the process of testicular steroidogenesis with cholesterol (CHOL) as the initial precursor. It is known that T levels gradually decrease, along with an increase in CHOL, LDL-C, triglycerides (TG), and a decrease in HDL-C in advanced stages of life. Dietary restriction (DR) ameliorates lipid status and raises T levels in obese and overweight men. Here, we investigated whether the beneficial effects of DR on serum lipid status consequently improve T production at advanced stages; therefore, we exposed male <i>Wistar rats</i> to long-term DR (LTDR, 18 months). We confirmed an age-related decrease in serum T levels, reduced expression of genes and proteins of steroidogenic machinery with a simultaneous increase in serum CHOL, LDL-C, and TG levels. LTDR additionally decreased T synthesis, expression of <i>Star</i>/StAR and <i>Cyp11a1</i>/CYP11A1, and testicular CHOL levels. At the same time, LTDR reduced serum CHOL, LDL-C, and TG levels and increased HDL-C levels. To confirm that the effects of DR are determined by the duration of the treatment, we also checked the effects of the short-term DR (STDR, 3 months) and demonstrated that STDR did not alter T levels and did not affect serum lipids. Our results indicate the importance of sustained systemic lipid homeostasis for T production in advanced life stages and show that the effects of restricted food intake on testicular androgen capacity depend on the duration of DR.</p>","PeriodicalId":12473,"journal":{"name":"Frontiers in Nutrition","volume":"12 ","pages":"1665682"},"PeriodicalIF":4.0,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12490992/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145232051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evidence is limited for the differences in the underlying relationships between nutritional habits, physical measures and psychological features. This study applies network analysis to visualize the interrelationships between nutritional dietary patterns, physical measures and psychological variables in young overweight or obese adults. In addition, we identified the nodes with the highest centrality indexes, and explored their empirical modularity. Stratified networks were obtained separately for MHO versus MUO subsamples, in order to explore differences in metabolic status.</p><p><strong>Methods: </strong>Data were collected from <i>N</i> = 188 young overweight or obese adults (university students, men and women aged 18 and 25 years) and subsequently analyzed.</p><p><strong>Results: </strong>In the MHO group, stress was identified as the bridge node, with the strongest connections with other psychological features (depression and anxiety), physical measures (body mass index, triacylglycerol, hypertension and glucose) and a nutritional pattern characterized by the intake of carbohydrates, fat and sodium. In contrast, in the MUO group, a nutritional pattern characterized by high consumption of fats and sodium, closely followed by cholesterol levels, emerged as the bridge node, with strong links to other dietary habits and variables.</p><p><strong>Conclusion: </strong>Identification of the most influential nodes among young individuals with and without cardio-metabolic risk factors provides valuable insights for the design of targeted treatment strategies.
