Special Issue Information

Dear Colleagues,

Non-transmissible chronic diseases (NTCDs) are a big concern worldwide, primarily due to persistent inflammation and altered food ingestion. In recent years, a substantial piece of research addressed the impact of nutrition on several NTCDs such as metabolic syndrome (MS), type II diabetes mellitus, obesity, dyslipidemia, cardiometabolic disease and related disorders. Food lipids and mineral content are fundamental in this aspect, especially in metabolic syndrome, mediating the gut microbiota. The characteristics of consumed fatty acids are crucial in such diseases, mainly when we highlight the essential polyunsaturated fatty acids (PUFAs). Nutraceutical foods are essential in the action mechanisms of comorbidities since healthy lifestyles and food chemical characteristics can attenuate them. Genetic predisposition is strongly related to metabolic changes. Several pre-clinical and clinical studies have been developed to show the importance of such alterations over life, demonstrating the importance of nutrigenomic studies.

Hence, authors are invited to contribute original research comprising in vitro and analytical studies on animals and humans with novel results. Narrative systematic reviews or meta-analyses will also be accepted.

Grape seeds are rich in bioactive substances, including polyphenols, terpenoids, and phytosterols. Linseed (Linum usitatissimum L.) boasts a high concentration of polyunsaturated fatty acids (PUFAs), lignans, phytoestrogens, and soluble fibers, all contributing to its therapeutic potential.

Grape seeds are rich in bioactive substances, including polyphenols, terpenoids, and phytosterols. Linseed (Linum usitatissimum L.) boasts a high concentration of polyunsaturated fatty acids (PUFAs), lignans, phytoestrogens, and soluble fibers, all contributing to its therapeutic potential. In this study, we pioneered the formulation of an oil blend (GL) combining grape seed oil (G) and golden linseed oil (GL) in equal volumes (1:1 (v/v)) and we evaluated in terms of the nutritional, physical, and chemical properties and their influence in an in vivo experimental model. We analyzed the oils by performing physical–chemical analyses, examining the oxidative stability using Rancimat; conducting thermal analyses via thermogravimetry/derivative thermogravimetry (TG/DTG) and differential scanning calorimetry (DSC), performing optical UV–vis absorption analyses; examining the fluorescence emission–excitation matrix, total carotenoids, and color, and conducting metabolic assessments in an in vivo experimental trial. The fatty acid profile presented a higher fraction of linoleic acid (C18:2) in G and GL and alpha-linolenic acid (C18:3) in L. The acidity and peroxide indices were within the recommended ranges. The TG/DTG, DSC, and Rancimat analyses revealed similar behaviors, and the optical analyses revealed color variations caused by carotenoid contents in L and GL. In the in vivo trial, G (G2: 2000 mg/kg/day) promoted lower total consumption, and the blend (GL: 2000 mg/kg/day) group exhibited less weight gain per gram of consumed food. The group with G supplementation (G2: 2000 mg/kg/day) and GL had the highest levels of HDL-c. The group with L supplementation (L2: 2000 mg/kg/day) had the lowest total cholesterol level. The L2, G1 (1000 mg/kg/day), and G2 groups exhibited the lowest MCP-1 and TNF-α values. Additionally, the lowest adipocyte areas occurred in G and GL. Our results suggest that this combination is of high quality for consumption and can influence lipid profiles, markers of inflammation, and antioxidant status. Full article
