Article Abstract

Fish oil (FO) has garnered attention in recent decades because of its omega-3 fatty acid (n-3 FAs) content, which is essential for healthy functions. However, the broad application of FO in food products has pros and cons because n-3 FAs are highly prone to oxidative deterioration, leading to product rejection. Enriching food products with FO is an effective strategy to boost the accumulation of n-3 FAs in the body. The n-3 FAs are considered essential lipids, and their consumption helps maintain normal triacylglycerol and cholesterol levels in the blood, decreases the risk of cancer and cardiac disorders, and augments brain function. The n-3 FAs obtained from FO can be added to animal diets or food products as free FO or protected FO. In this review, we focus on elucidating the benefits and challenges of adding FO to several animal-based foods, such as meat-, egg-, and milk-based products. In addition, we discuss the preparation of edible film/coating-forming emulsions and the design of FO-enriched double-layered edible films/coatings.

Background: Sleep disorders show comorbidity with depression and Alzheimer's disease (AD), especially in ageing. However, the neuroimmunological role of sleep deprivation (SD) as possible inducer to these conditions remains unknown. Omega-3 fatty acids (n-3 FAs) can improve depression and AD through anti-inflammation, up-regulating neurotrophins and normalizing neurotransmitters, while their therapeutic effects on sleep deprivation (SD)-induced changes in different ages requires investigation.

Department of Biomedical, Dental, Morphological and Functional Images Sciences (BIOMORF), University of Messina, Viale Annunziata, 98100 Messina, Italy.

Although the strawberry tree ( L.) has been long considered a neglected species of the Mediterranean maquis, the valorization of its fruit production may enhance its socioeconomic value, especially in rural areas. In this study, strawberry trees from different Sicilian sites were investigated in terms of macronutrients, fatty acid (FA) composition, tocopherols, total phenols, carotenoids, and minerals.

Background And Aims: Children infected with SARS-CoV-2 may develop multisystem inflammatory syndrome (MIS-C) 4-6 weeks after exposure. MIS-C is characterized by elevated markers of inflammation and low blood values of linoleic acid (LA), arachidonic acid (AA) and docosahexaenoic acid (DHA) during acute phase. The aim of this pilot exploratory study was to assess the short-term beneficial impact on the blood fatty acid profile following DHA supplementation in children who have suffered from MIS-C.
