Gut microbiota or the population of microbial inhabitants in the intestine, plays a key role in digestion and maintenance of overall health. Intestinal microbes metabolize dietary components into beneficial fatty acids (FAs), supporting metabolism and maintaining host body homeostasis. Metabolites originating from polyunsaturated fatty acids (PUFAs), influenced by gut microbes such as Lactobacillus plantarum, exhibit potent effects on inflammation and immune responses. The researchers used antigen-stimulated spleen cells to elicit an enhanced immune response. Subsequently, they investigated the impacts of different polyunsaturated fatty acid (PUFA) derivatives, focusing on metabolites of linoleic acid, a prevalent dietary fatty acid. Their findings revealed...

A new review highlights the significant role of dietary lipids in preventing brain aging and cognitive decline. As the global burden of aging-related brain diseases, particularly dementia, continues to rise, this research offers promising insights into potential nutritional interventions that could improve brain function during aging. The review focuses on the intricate relationship between lipid homeostasis and brain aging, emphasizing the importance of maintaining synaptic plasticity to prevent cognitive impairment. By examining evidence from epidemiological and animal studies, the research team demonstrates the crucial functions of polyunsaturated fatty acids (PUFAs), specifically phospholipids such as phosphatidylcholine, phosphatidylserine, and plasmalogen, in promoting...
