An egg is a nutrient-dense food that contains protein, fats, vitamins, and minerals. It is proven that the consumption of eggs influences serum lipid concentration. Therefore, a study was conducted to investigate the effect of normal and omega-3 eggs on serum lipids profiles. Lipids were extracted from egg yolks and analyzed for fatty acids content. The present research is a crossover study design in which 20 participants were recruited randomly, and all subjects received three treatments: no eggs, omega-3 eggs, and normal eggs. However, fasting blood was drawn at baseline and the end of each diet period and analyzed for serum lipids, blood glucose, and insulin level. Omega-3 egg treatment showed reduction in the serum total cholesterol by 16.57 mg/dl ( < .001), triglyceride by 17.48 mg/dl, and increase in HDL cholesterol concentration by 0.48 mg/dl ( < .001) as compared to no-egg. A significant ( < .05) reduction in blood pressure by 8.34/8.67 mm/Hg and insulin level was observed due to omega-3 egg consumption which indicates that omega-3 fatty acids improve insulin sensitivity. On the other hand, regular egg intake elevates serum total cholesterol and triglycerides concentration but decreases blood pressure. It was concluded that omega-3-enriched egg consumption had a positive effect on the serum lipid profile and blood pressure of patients with metabolic syndrome as compared to normal eggs.

The objective of this experiment is to investigate the effects of SAP or SAO as ω-3 PUFA raw materials on production performance, egg quality, serum immunity, serum lipids, and fatty acid deposition patterns in the eggs of laying quails. Chinese yellow-feathered quails served as the experimental subjects. A single-factor design was employed to randomly assign 1288 quails into four treatment groups, with seven replicates per treatment and 46 birds in each replicate.

Background: Primary ovarian insufficiency (POI) is a critical cause of infertility and is increasingly recognized as a complex metabolic disorder. Dietary factors may influence the risk of POI, but causal relationships remain unclear.
Methods: We conducted an MR study using genetic instrumental variables for 83 dietary preferences from the UK Biobank, with the Inverse Variance Weighted method as the primary analysis.

Although the metabolism of yolk lipids such as docosahexaenoic acid (DHA) is pivotal for embryonic development, the underlying mechanism remains elusive. Here we find that the zebrafish hydroxysteroid (17-β) dehydrogenase 12a (hsd17b12a), which encodes an intestinal epithelial-specific enzyme, is essential for the biosynthesis of long-chain polyunsaturated fatty acids in primitive intestine of larval fish. The deficiency of hsd17b12a leads to severe developmental defects in the primitive intestine and exocrine pancreas.

Obesity, as defined by the World Health Organization (WHO), is excessive fat accumulation that can pose health risks and is a disorder of the energy homeostasis system. In typical westernized diets, ω-6 polyunsaturated fatty acids (PUFAs) vastly exceed the amount of ω-3 PUFAs, with ω-6/ω-3 ratios ranging from 10:1 to 25:1. ω-6 PUFAs, such as arachidonic acid, have pro-inflammatory effects and increase obesity.

Indigenous animal genetic resources should be preserved because of their well adaptation to the environment, their tolerance to low food availability and their sociocultural importance. The characterization of the quality of the products generated by heritage breeds may bring more arguments to encourage the raising of these animals. This study aimed at evaluating the egg performance and quality of Spanish indigenous Black Castellana (BC) breed as compared with a selected strain (Lohmann LSL-Classic).
