Seaweed presents a sustainable alternative source of valuable fatty acids (FAs) involving omega-3 (n-3) and omega-6 (n-6). As such, there is great potential to reduce pressure on wild fish populations, helping combat overfishing its associated global impacts. This study explored the effect various environmental factors FA content profile Ulva lactuca using indoor photobioreactors. The taxonomic identity U. was confirmed through DNA sequencing 3 markers (rbcL, ITS, tufa). effects temperature (8, 20, 30 °C), seawater salinity (3.5, 3.0, 2.5, 2.0% w/v), nutrient type concentration (0 or 6.4 ppm, consisting 50% w/w N-NO3, N-NH4, 0-1 ppm P-PO4), irradiance (50, 100, 150 μmol photons m-2 s-1) were evaluated. assessed their influence lactuca's biomass production rate (BPR), dry weight (DW), ash (AC), composition after 7 21 days. results revealed that days, polyunsaturated (PUFA) decreased with increasing (i.e., 38.9% ± 0.7, 33.8% 0.4, 27.0% 6.6% 0.1 for 2.0, 3.5% w/v, respectively). n-3 days increased significantly under following conditions: 8 °C, 2.5% nitrogen without addition phosphorous, an irradiation 50 s-1, affording low n-6/n-3 proportion fits desirable level n6/n3 ratio (1-10) balanced nutritional diet.

Veganism is gaining popularity due to its ethical, health, and environmental benefits. However, many vegans face challenges in obtaining a complete essential amino acid profile from plant sources, making diversified protein sources crucial for balanced nutrition. Macroalgae, nutrient-rich food traditionally consumed Asia, offers solution by providing both non-essential acids vital optimal health. This study analyzed the profiles of seven macroalgae species northwest coast Iberian Peninsula using HPLC with fluorescence detection. All samples contained acids, although tryptophan was mostly absent. Brown algae displayed higher aspartate glutamate levels, contributing "umami" flavor, while red exhibited histidine lysine concentrations. These findings highlight as valuable source vegan diets, offering comprehensive personalized nutrition plans.

Protein is a fundamental macronutrient in the human diet. It supplies our organisms with essential amino acids, which are needed for growth and maintenance of cells tissues. Conventional protein sources, despite their complete acid profiles excellent digestibility, have proven negative impact on environment. Furthermore, production poses many ethical challenges. This review aims to present nutritional, more ethical, environmentally friendly alternatives that could serve as potential sources population. The available literature alternative has been analyzed. Based research conducted, various products identified described, including plant-based such soybeans, peas, faba beans, lupins, hemp seeds; aquatic algae, microalgae, water lentils; well insect-based microbial cell-cultured meat. Despite numerous advantages, lower environmental impact, higher standards production, beneficial nutritional profiles, not without limitations. These include bioavailability certain presence antinutritional compounds, technological challenges, issues related consumer acceptance. Nevertheless, proper dietary composition, optimization processes, further advancements, presented can constitute valuable sustainable growing global

The growing demand for sustainable and nutrient-rich food sources has positioned macroalgae as a promising alternative product development. This study investigates the extraction characterization of hydrocolloids from three red species (Chondrus crispus, Gracilaria gracilis, Gelidium corneum) using water bath (WB), ultrasound (US), hybrid ultrasound–water (USWB) treatments 45 60 min. physicochemical properties extracts, including rheological behavior, particle size distribution, antioxidant activity, texture, were assessed. results show that C. crispus produced firmest gels due to its high carrageenan content, with WB USWB yielding most stable gel structures. In contrast, G. gracilis corneum exhibited lower strength, consistent their agar composition. WB-treated samples demonstrated superior retention, while US treatment was more effective in preserving color stability. findings highlight viable conventional hydrocolloids, reinforcing potential natural gelling agents, thickeners, stabilizers pharmaceutical industries. provides comparative evaluation WB, US, methods, offering insights into optimizing hydrocolloid enhanced functionality sustainability.

The present study adopted a diverse approach to obtain antioxidant peptides from red seaweed, starting with an aqueous extraction of the entire seaweed followed by enzymatic hydrolysis solid residues first step. Additionally, impact three different pH levels (i.e. 3, 6, and 9) during phase was examined for their influence on outcomes. findings revealed that fraction resulting sequential process contained significantly higher proteins amino acids compared other fractions (p < 0.05). Furthermore, (IC50 ranging 2.29 8.15) proved be more effective free radical scavengers than liquid either 9.03 10.41 or not obtained at highest concentration tested) both stages Among fractions, those produced under alkaline conditions did exhibit as potent scavenging abilities acidic nearly neutral conditions. most metal ion chelating activity found in derived subsequent stage, particularly 3 = 0.63 ± 0.04) 6 0.89 0.07), which were initial stage Given no significant difference noted total phenolic content these corresponding (3.79 0.05 vs. 3.48 0.02 2.43 0.22 2.51 0.00 6) > 0.05), demonstrated properties might attributed potential roles bioactive such histidine, glutamic acid, aspartic tyrosine, methionine, whether integrated within structure peptides.

Metabolic Syndrome (MetS) is a complex, multifactorial condition characterized by risk factors such as abdominal obesity, insulin resistance, dyslipidemia and hypertension, which significantly contribute to the development of cardiovascular disease (CVD), leading cause death worldwide. Early identification effective monitoring MetS crucial for preventing serious complications. This article provides comprehensive overview various biomarkers associated with MetS, including lipid profile markers (triglyceride/high-density lipoprotein cholesterol (TG/HDL-C) ratio apolipoprotein B/apolipoprotein A1 (ApoB/ApoA1) ratio), inflammatory (interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), plasminogen activator inhibitor type 1 (PAI-1), C-reactive protein (CRP), leptin/adiponectin ratio, omentin fetuin-A/adiponectin oxidative stress (lipid peroxides, nucleic acid oxidation, gamma-glutamyl transferase (GGT), uric acid) microRNAs (miRNAs) miR-15a-5p, miR5-17-5p miR-24-3p. Additionally, this review highlights importance in need advancements their use improving prevention treatment. Seaweed therapy also discussed significant intervention due its rich content fiber, antioxidants, minerals bioactive compounds, help improve health, reduce inflammation, increase sensitivity promote weight loss, making it promising nutritional strategy managing metabolic health.
