Abstract
Omega-3 (n-3) fatty acids are widely recognized as an important factor regulating a number of human disorders. The main source of omega-3 fatty acids) in the diet is seafood, especially cold-water fishes (EPA and DHA) and some vegetable oils (ALA). Because the dietary intake of omega-3 fatty is insufficient, other dietary options are being sought. Research has shown that stearidonic acid (SDA), present in some vegetable oils, may increase the EPA levels. The main objective of this article is to review current knowledge regarding the impact of stearidonic acid on human health. A number of studies have demonstrated that SDA has a beneficial effect on several diseases, such as hypertriglyceridemia, cardiovascular and inflammatory diseases, diabetes, and some types of cancer.
INTRODUCTION
Fatty acids are compounds with a diverse chemical structure and many important biological functions. With regard to prevention and treatment of several diseases, special attention should be given to omega-3 acids, which are necessary for the proper functioning of the human body (1). They influence the regulation of the cardiovascular system, blood pressure, plasma triglyceride concentration, immune response and inflammatory processes, cancer development, regulation of hormones and neuromediators, gene expression, kidney functioning, and the proper functioning of neurons and the retina (2). The main source of omega-3 fatty acids in the diet is seafood, especially cold-water fishe ... ...
