Long-chain polyunsaturated fatty acids and brain functions

Introduction and purpose. Long-chain ω-3 PUFAs such as DHA and EPA are often present in high amounts in algae and fish. DHA in particular is crucial for the proper progress and functioning of the cerebrum because it is the main structural component of ω-3 PUFA in the brain. This makes it an indispensable element of the phospholipids of the nervous membrane. The purpose of this article is to present the assistance of Omega-3 acids in the functioning of the nervous system. State of knowledge. The text discusses a literature review focusing on the impact of omega-3 fatty acids. Polyunsaturated fatty acids (PUFAs) are essential for overall health and have been extensively studied for their contributions to human wellbeing and disease management. Recent research indicates their effectiveness in preventing and treating various diseases. Omega-3 PUFAs have been identified as therapeutic agents, particularly in combating inflammatory conditions like cardiovascular and neurodegenerative diseases. Material and method. The aim of this article is to present the benefits of omega-3 fatty acids augmentation. We used publications outlining properties of polyunsaturated fatty acids on the brain, articles presenting the outcomes of polyunsaturated fatty acids were reviewed using the PubMed platform. The review included the keywords “Omega-3 fatty acids”, “DHA”, “EPA”, “PUFA”. Summary. The review managed to present the influence of Omega-3 fatty acids on brain development, aging and a useful addition to the treatment of diseases such as Alzheimer's and drug-resistant epilepsy. By receiving multiple studies, the author confronted various opinions of specialists regarding the approach to supplementation of PUFA. Additionally, the conclusion was that marine fish oils in the appropriate doses do not cause any serious side effects. Considering their broad positive effect on the nervous system, every person should consume them.
