To assess the suitability of southern-Australian macroalgae as potential marine resources for fatty acids (FA), and in particular polyunsaturated fatty acids (PUFA), analysis of 61 species, comprising of 11 Chlorophyta, 17 Phaeophyceae (Ochrophyta) and 33 Rhodophyta, was conducted. Total fatty acid (TFA) concentrations varied considerably (between 0.6 and 7.8 in % of dry weight (DW)) between species, with on average the highest concentrations being in the Phaeophyceae, then the Chlorophyta, and with the Rhodophyta recording the lowest average concentrations. Results revealed significant differences in the fatty acid profiles of the three algal groups. Most species exhibit high proportions of PUFA in their fatty acid profile and a low ratio of n-6/n-3 PUFA. These properties highlight the potential for southern-Australian macroalgae to be used for these FA in food, animal feed and nutraceutical applications.

Background: Jianwei Xiaoshi oral liquid (JWXS), a classical traditional prescription comprising various edible medicinal plants, has demonstrated significant efficacy in treating paediatric indigestion. It originates from Jianpi Pill, which is developed in the Ming Dynasty and nourishes the spleen and regulates gastrointestinal function. However, the specific molecular mechanisms involved remain unclear.

Recently, Torres-Romero et al. identified a novel lipid droplet (LD)-associated protein, α/β-hydrolase domain containing protein 1 (ABHD1), in algae. Structurally, ABHD1 promotes the budding and growth of LDs and, functionally, it hydrolyzes lyso-diacylglyceryl-N,N,N-trimethylhomoserine (lyso-DGTS) to generate glyceryl-N,N,N-trimethylhomoserine (GTS) and free fatty acids (FFAs).

Background: Modern dietary trends have led to an increase in foods that are relatively high in n-6 polyunsaturated fatty acids (PUFAs) and low in n-3 PUFAs. We previously reported that the offspring of mother mice that consumed a diet high in n-6 linoleic acid (LA) and low in n-3 α-linolenic acid (ALA), hereinafter called the LA/ALA diet, exhibit behavioral abnormalities related to anxiety and feeding.
Objective: We currently lack a comprehensive overview of the behavioral abnormalities in these offspring, which was investigated in this study.

This study aimed to examine the relationship between eating behavior, nutritional status and mental health. It is a cross-sectional study conducted on a sample of 360 healthy individuals aged 19-64 years. The General Health Questionnaire (GHQ-12) was used to evaluate mental health and the Three-Factor Eating Scale (TFEQ-R21) was used to assess eating behavior.
