Background: Knowledge about the diet quality among youth who follow different types of plant-based diets is essential to understand whether support is required to ensure a well-planned diet that meets their nutritional needs. This study aimed to investigate how food groups, macronutrient intake, and objective blood measures varied between Norwegian youth following different plant-based diets compared to omnivorous diet.

Methods: Cross-sectional design, with healthy 16-to-24-year-olds (n = 165) recruited from the Agder area in Norway, following a vegan, lacto-ovo-vegetarian, pescatarian, flexitarian or omnivore diet.

Omega (ω)-3 fatty acids (FAs) are essential components of cell membranes that also serve as precursors of numerous regulatory molecules. α-linolenic acid (ALA), one of the most important ω3 FAs in plants, is synthesized in both the plastid and extraplastidial compartments. FA Desaturase (FAD) 3 is an extraplastidial enzyme that converts linoleic acid (LA) to ALA.

Flaxseed, a rich source of omega-3 polyunsaturated fatty acid alpha-linolenic acid (ALA), lignans, and soluble fiber, has attracted attention for its potential to improve multiple cardiometabolic risk factors. While its benefits are well-recognized, comprehensive evaluations of its direct impact on clinical outcomes, such as the prevention or progression of cardiometabolic diseases, remain limited. Additionally, its potential to support healthy aging and longevity through fundamental biological mechanisms has not been fully elucidated.

This work aims to provide a basis for the enhancement of fucoxanthin (FCX) and eicosapentaenoic acid (EPA) biosynthesis in the microalga Phaeodactylum tricornutum using metabolomics and computational biology. To achieve this, both targeted (UHPLC and GC-FID) and untargeted (FTIR and NMR) analyses were conducted throughout various stages of cell cultivation. Targeted analyses revealed that EPA concentrations peaked at the end of the logarithmic growth phase, while fucoxanthin levels remained consistent from the onset of this phase through to the stationary phase.
