Breastfeeding women require specific nutrition to support the quality and secretion of breast milk, which can be achieved through the development of analog rice. Several potential alternatives to develop analog rice, including sago and corn flour, can be developed with the addition of moringa leaf powder due to its high nutritional composition and bioactive compounds, particularly high protein, iron, phytosterols, and flavonoids, which are suitable for breastfeeding women. However, as a new product, besides considering its nutritional value, developing the preferred and acceptable formulation of analog rice remains challenging. This research aims to gain the best formulation and investigate the physicochemical and sensory properties. Three formulations of analog rice were applied in this study utilizing extrusion technology, comprising sago, corn flour, and moringa leaf powder in ratio variations as follows: A, 60:37:3; B, 70:25:5; C, 80:10:10. Overall, the analog rice produced had a green color, a sticky texture, a distinct moringa aroma, and a slightly bitter taste, with Formulation C being most preferred (overall organoleptic value of 2.5, categorized as neutral), containing 6.22 ± 0.83% moisture, 1.04 ± 0.07% ash, 4.08 ± 0.17% protein, 0.46 ± 0.09% fat, 88.21 ± 0.59% carbohydrate, 3.42 ± 1.54% crude fiber, 382.62 ± 3.75 Kcal, 40.12 ± 13.38 ppm iron, 1.09 ± 0.05% sitosterol, 1.16 ± 0.03% stigmasterol, and 0.19 ± 0.07% flavonoid levels. The analog rice provides high energy and lactation-supporting bioactive compounds (iron, phytosterols, and flavonoids), demonstrating potential as a sustainable dietary intervention. This study offers a novel approach through the development of extruded analog rice, which transforms local ingredients into a functional food targeting maternal nutritional gaps by synergizing sago, corn flour, and moringa leaf powder.

Background/Objectives: High concentration of plasma low-density lipoprotein cholesterol (LDL-C) is the predominant cause of atherosclerotic cardiovascular disease progression and coronary heart disease. Nutraceutical combination together with a cholesterol-lowering action provides an alternative to pharmacotherapy in patients reporting intolerance to statins and in subjects with low cardiovascular risk. The effects on lipid parameters were evaluated over 6 months for a food supplement containing aqueous extract of Berberis aristata and Olea europea, fenugreek seed extract, water/ethanol extract of artichoke leaf and phytosterols from sunflower seeds (Ritmon Colesystem^®). Methods: Laboratory data were obtained at baseline from 44 otherwise healthy subjects (33 males, mean 50 ± 11 years) without cardiovascular disease having LDL-C in the range 115 to 190 mg/dL pharmacologically untreated for hypercholesterolemia. Subjects were re-evaluated at 1, 3 and 6 months during which they took one tablet of Ritmon Colesystem^® after dinner. Results: At baseline, the mean values were 151 ± 21 mg/dL for LDL-C, 223 ± 24 mg/dL for total cholesterol (T-C), 52 ± 14 mg/dL for high-density lipoprotein cholesterol (HDL-C), and 124 ± 58 mg/dL for triglycerides. A significant reduction in LDL-C was observed; 9 mg/dL (95% confidence interval 3–14), 10 (4–17) and 7 (1–14) at 1, 3 and 6 months. A similar significant trend was detected for T-C while triglycerides did not show significant changes and HDL-C had lower values only at 3 months. Conclusions: These nutraceuticals in individuals with sub-optimal blood cholesterol levels at intermediate–low cardiovascular risk reduced LDL-C and T-C over 6 months contributing to the improvement of cholesterol control by dietary supplements.

Inonotus obliquus, a medicinal mushroom valued for its bioactive compounds, has not been previously characterized from Romanian sources. This study presents the first comprehensive chemical and biological screening of I. obliquus, introducing novel polymer-based encapsulation systems to enhance the stability and bioavailability of its bioactive constituents. Two distinct delivery systems were designed to enhance the functionality of I. obliquus extracts: (i) microencapsulation in maltodextrin (MIO) and (ii) a sequential approach involving preparation of silver nanoparticle-loaded I. obliquus (IO–AgNPs), followed by microencapsulation to yield the hybrid MIO–AgNP system. Comprehensive metabolite profiling using GC–MS and ESI–QTOF–MS revealed 142 bioactive constituents, including terpenoids, flavonoids, phenolic acids, amino acids, coumarins, styrylpyrones, fatty acids, and phytosterols. Structural integrity and successful encapsulation were confirmed by XRD, FTIR, and SEM analyses. Both IO–AgNPs and MIO–AgNPs demonstrated potent antioxidant activity, significant acetylcholinesterase inhibition, and robust antimicrobial effects against Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa, and Escherichia coli. Cytotoxicity assays revealed pronounced activity against MCF-7, HCT116, and HeLa cell lines, with MIO–AgNPs exhibiting superior efficacy. The synergistic integration of maltodextrin and AgNPs enhanced compound stability and bioactivity. As the first report on Romanian I. obliquus, this study highlights its therapeutic potential and establishes polymer-based nanoencapsulation as an effective strategy for optimizing its applications in combating microbial resistance and cancer.

Soybean (Glycine max (L.) Merrill) is a major oilseed crop rich in phytosterols and tocopherols, compounds associated with functional and nutritional properties of vegetable oils. This study aimed to apply, for the first time, Independent Component Analysis (ICA) to discriminate the composition of phytosterols (β-sitosterol, campesterol, stigmasterol) and tocopherols (α, β, γ, δ) in 20 soybean genotypes—14 non-transgenic and six transgenic—cultivated in two major producing regions of Paraná state, Brazil (Londrina and Ponta Grossa). Lipophilic compounds were extracted from soybean seeds, quantified via gas chromatography and HPLC, and statistically analyzed using ICA with the JADE algorithm. The extracted independent components successfully differentiated soybean varieties based on phytochemical profiles. Notably, transgenic cultivars from Ponta Grossa exhibited higher levels of total tocopherols, including α- and β-tocopherol, while conventional cultivars from both regions showed elevated phytosterol content, particularly campesterol and stigmasterol. ICA proved to be a powerful unsupervised method for visualizing patterns in complex compositional data. These findings highlight the significant influence of genotype and growing region on the nutraceutical potential of soybean, and support the use of multivariate analysis as a strategic tool for cultivar selection aimed at enhancing functional quality in food applications.

Pistachio nuts are among the 50 best foods with the highest antioxidant potential. They have a balanced content of mono- (~70%) and polyunsaturated (~20%) fatty acids, minerals, and bioactive compounds such as tocopherols, phytosterols, and phenolic compounds, which have shown rapid accessibility in the stomach. Pistachio consumption provides several health benefits, primarily due to its antioxidant properties and high content of essential nutrients. In this study, we analyzed the mineral composition, total phenolic content (TP), antioxidant activity (AA), and UHPLC/MS-MS polyphenolic profile of three Argentinian pistachio crops. Additionally, the physicochemical parameters and the elemental profiles of the growing soils were determined, as they influence mineral uptake and the synthesis of bioactive compounds in pistachio kernels. The TP was not significantly modified by the growing soils, with Crop3 presenting the highest TP content (276 ± 14 mg GA/100 g DW). Crop3 exhibited 18% higher TP content compared to Crop2. Similarly, FRAP values ranged from 28.0 to 36.5 mmol TE/100 g DW, with Crop1 showing a 30% increase compared to Crop2. DPPH values varied from 19.0 to 24.3 mmol TE/100 g DW, with Crop1 displaying 28% higher activity than Crop2. However, the polyphenolic profile was similar for all crops analyzed. Thirty compounds were identified; only Crop 1 contained the flavanone eriodyctiol and the isoflavone genistein, while the flavanone naringenin and the flavone luteolin were identified in Crop1 and Crop3. Regarding mineral content, the pistachio kernels mainly contained K, Ca, and Mg. Multivariate analyses revealed distinct elemental and antioxidant profiles among crops. LDA achieved classification accuracies of 77.7% for soils and 74.4% for kernels, with Pb, Zn, Cu, Rb, Sr, and Mn as key discriminants. CCA confirmed strong soil–kernel mineral correlations (r = 1), while GPA showed higher congruence between antioxidant traits and kernel composition than with soil geochemistry. These findings underscore the importance of soil composition in determining the nutritional quality of pistachio kernels, thereby supporting the beneficial health effects associated with pistachio consumption.

Cholesterol accumulation plays a significant role in the pathogenesis of metabolic-dysfunction-associated steatotic liver disease (MASLD), yet changes in cholesterol homeostasis in MASLD remain insufficiently investigated. This study aimed to examine alterations in cholesterol synthesis and absorption by measuring plasma levels of endogenous cholesterol precursors (as markers of synthesis) and phytosterols (as indicators of absorption). A total of 124 MASLD patients and 43 healthy individuals were included. Our results showed higher plasma concentrations of lathosterol in the MASLD group (p = 0.006), in parallel with comparable concentrations of desmosterol (p = 0.472) and all analyzed phytosterols in both groups. Correlation analysis showed that both lathosterol and desmosterol were positively associated with non-invasive hepatic steatosis indices: FLI, HSI, and TyG index (p < 0.01, p < 0.01, and p < 0.05, respectively). Multivariate linear regression further confirmed that these synthesis markers remained significant predictors of FLI (p = 0.010), HSI (p = 0.013), and TyG index (p = 0.002), even after adjusting for other relevant variables. These findings indicate that MASLD is associated with a shift in cholesterol homeostasis towards enhanced endogenous cholesterol synthesis. Full article

Familial hypercholesterolemia (FH) is a genetic disorder marked by significantly elevated levels of low-density lipoprotein cholesterol (LDL-C) since childhood, substantially increasing the risk of premature atherosclerosis and cardiovascular disease. While dysfunction of hepatic LDL-C receptors is the main underlying cause, the gastrointestinal tract plays a key role in cholesterol homeostasis and represents an important therapeutic target. Inhibition of intestinal cholesterol absorption has emerged as an effective strategy in the management of pediatric FH, particularly in patients for whom statins may not be the ideal first-line treatment. Ezetimibe, an inhibitor of the Niemann-Pick C1-like 1 (NPC1L1) protein, has been shown to reduce LDL-C levels in children with FH, with a greater efficacy observed when used in combination with statins. Bile acid sequestrants also enhance cholesterol excretion but are often limited by gastrointestinal side effects, while dietary interventions, such as phytosterol supplementation and fiber-enriched diets, provide additional benefits in lowering LDL-C and are generally well tolerated. Emerging therapies, including microbiota-targeted strategies and novel cholesterol absorption inhibitors, show promise for expanding future treatment options. This review explores the mechanisms of intestinal cholesterol absorption and their relevance to pediatric FH. We examine key pathways, including dietary cholesterol uptake through NPC1L1, bile acid reabsorption, and cholesterol efflux mediated by ATP-binding cassette transporters, while also discussing clinical and experimental evidence on pharmacological and dietary interventions that modulate these pathways. A deeper understanding of cholesterol metabolism, the emerging role of the gut microbiota, and innovative therapeutic agents can support the development of more effective and personalized approaches to the treatment of children with FH.

Breast milk is the optimal nutrition for infants, yet lactation insufficiency remains a common cause of early breastfeeding cessation. Moringa oleifera has been traditionally used as a galactagogue due to its rich micronutrient and phytosterol content. This systematic review assessed the effects of Moringa leaf supplementation on prolactin levels and breast milk volume in postpartum mothers with lactation insufficiency. A systematic search following PRISMA guidelines, was conducted for randomized controlled trials involving healthy postpartum women supplemented with Moringa oleifera. Risk of bias was evaluated using the Cochrane Risk of Bias Tool. Eight studies met the inclusion criteria, with intervention durations ranged from 3 to 10 days. Moringa supplementation increased significantly breast milk volume by up to 400 mL/day compared to controls. Serum prolactin levels also rose significantly with a mean increase of 231.72 ng/mL Most studies exhibited low to moderate risk of bias, though one study exhibited high risk due to lack of binding and subjective outcome measurement. Moringa oleifera leaf supplementation appears to enhance lactation by increasing milk volume and prolactin levels in postpartum mothers. However, further longer-term studies are needed to establish optimal dosing, sustained effectiveness, and safety. Full article

Celtis iguanaea, widely used in Brazilian folk medicine, is known for its analgesic and anti-inflammatory properties. This study evaluated the in vitro antioxidant capacity and the in vivo antinociceptive and anti-inflammatory mechanisms of the standardized spray-dried Celtis iguanaea hydroethanolic leaf extract (SDCi). Phytochemical analysis showed that SDCi contains 21.78 ± 0.82 mg/g polyphenols, 49.69 ± 0.57 mg/g flavonoids, and 518.81 ± 18.02 mg/g phytosterols. UFLC-DAD-MS identified iridoid glycosides, p-coumaric acid glycosides, flavones, and unsaturated fatty acids. Antioxidant assays revealed an IC₅₀ of 301.6 ± 38.8 µg/mL for DPPH scavenging and an electrochemical index of 6.1 μA/V. In vivo, SDCi (100–1000 mg/kg, p.o) did not impair locomotor function (rotarod test) but significantly reduced acetic acid-induced abdominal writhing and both phases of the formalin test at higher doses (300 and 1000 mg/kg). The antinociceptive effects were independent of α-2 adrenergic receptors. SDCi also increased latency in the hot-plate test and reduced paw edema in the carrageenan model, accompanied by decreased IL-1β and increased IL-10 levels. Histological analysis showed a 50% reduction in inflammatory cell infiltration. These findings support SDCi as an effective anti-inflammatory and antinociceptive phytopharmaceutical intermediate, with potential applications in managing pain and inflammation. Full article

Beta-sitosterol (BS), a naturally occurring phytosterol abundant in plants, has been reported to exhibit diverse biological activities, including immunomodulatory and antiviral effects. Classical swine fever virus (CSFV), a member of the Pestivirus genus, remains a persistent threat to the swine industry worldwide, causing considerable economic damage. Our research found that BS significantly enhances the replication of both the CSFV-Shimen strain and the attenuated C-strain vaccine virus in PK-15 cells. Additionally, transcriptomic profiling (RNA-Seq) identified 175 differentially expressed genes (DEGs) following BS exposure, comprising 53 upregulated and 122 downregulated genes. Further results demonstrated that treatment with β-sitosterol suppressed IκBα expression, thereby activating the NF-κB pathway, and that knockdown of endogenous IκBα significantly promoted CSFV replication. These findings contribute to a deeper understanding of how BS influences the CSFV infection process, suggesting its role as a host lipid-associated factor facilitating viral propagation.

Phytosterols (PS) have specific oxidation rules in different lipid media. After oxidation, PS will form oxidation products, which has potential physiological toxicity to the human body. Camellia seed oil (CSO) is a unique emerging edible oil in China. This oil has a fatty acid composition similar to olive oil, in which oleic acid is dominant. In order to solve the thermal oxidation of PS in CSO at high temperature (180 °C), we studied its antioxidant strategy by evaluating different antioxidants. Four antioxidants—BHA, TBHQ, epigallocatechin gallate (EGCG), and α-tocopherol (VE)—along with one synergist, citric acid (CA), were selected and used in this study. The antioxidant effects of different combinations (single antioxidant, single antioxidant + CA, mixed antioxidant, mixed antioxidant + CA) were compared. After 180 min of heating, the PS and phytosterols oxidation products (7α-hydroxy-, 7β-hydroxy-, 5α,6α-epoxy-, 5β,6β-epoxy-, 7-keto-, and trihydroxy-PS) were estimated by GC-MS. Through comparative analysis, the results showed that the combination of mixed antioxidants and CA had the best antioxidant effect, and the inhibition rate of VE + TBHQ +CA was as high as 42%, which had a breakthrough significance for stabilizing the thermal oxidation of PS in camellia seed oil. At the same time, it also provides a valuable reference for ensuring the edible safety of camellia seed oil in Chinese food heating habits. Full article

Sitosterol (Sito) is a phytosterol with bioactive properties, including reducing atherosclerosis risk and anti-inflammatory and antitumoral effects. However, it can be oxidized by reactive oxygen species such as ozone (O₃), producing oxyphytosterols with harmful effects such as cytotoxicity, oxidative stress, and proatherogenicity. Ozone, a strong oxidant and common pollutant, can alter plant steroid compounds, raising concerns about dietary oxyphytosterol intake. Studies identify β-Secosterol (βSec) as the primary ozone-derived oxyphytosterol from Sito, exhibiting cytotoxic effects on HepG2 human liver tumor cells. This study investigated βSec’s biological effects on two rat liver cell lines: BRL-3A (immortalized) and HTC (tumoral), examining cell death, cell cycle progression, morphology, and cytoskeleton organization. While Sito influenced cell metabolic activity without affecting cell survival or morphology, βSec demonstrated significant cytotoxicity in both cell lines. It induced G0/G1 cell cycle arrest and disrupted cytoskeleton organization, with different implications: BRL-3A cells showed persistent cytoskeletal changes potentially linked to tumor induction, while HTC cells displayed chemoresistance, restoring cytoskeletal integrity and enhancing metastatic potential. These findings reveal βSec’s complex, context-dependent effects, suggesting it may promote tumor-like behavior in non-tumoral cells and resistance mechanisms in cancer cells, contributing to understanding oxyphytosterols’ implications for physiological and pathological conditions.
