摘要

The Developmental Origins of Health and Disease (DOHaD) hypothesis asserts that detrimental prenatal conditions, such as dietary deficiencies, may lead to enduring health consequences. Perinatal undernutrition, an important concern during fetal development, may affect growth and metabolic programming, resulting in lasting health implications. Maternal nutrition is crucial in modulating fetal endocrine systems and metabolic functions, influencing the development, blood circulation, and nutrient absorption. The present study examines the impact of perinatal undernutrition on the composition of gut microbiota and metabolite levels in offspring of undernourished dams, using an Albino Wistar rat model. Furthermore, we investigated the combined impact of astaxanthin (AsX) and docosahexaenoic acid (DHA) supplementation on cardiometabolic outcomes in these progenies. Astaxanthin, a powerful antioxidant, and DHA, an omega-3 fatty acid, have shown the ability to favorably alter the gut flora and metabolic pathways. The direct influence of AsX on gut microbiota remains unexplored, whereas DHA’s role in fostering beneficial microbes and regulating metabolite production is well documented. The current study used metabolomics and metagenomics to investigate the intricate relationship between metabolites and gut microbiota in health and disease, offering insights into fetal programming and possible strategies to improve offspring health. The results highlight the need to address perinatal undernutrition and enhance gut health through targeted dietary interventions to improve long-term health outcomes.
