title: Essential fatty acids in health and disease.
abstract: Essential fatty acids (EFAs) form an important component of cell membranes, are eicosanoid precursors and are therefore required for both the structure and function of every cell in the body. EFAs can modulate the activity of protein kinase C, T and B cell response, free radical generation and lipid peroxidation, lymphokine secretion and cell proliferation. EFAs also have anti-mutagenic, anti-bacterial, anti-fungal and anti-viral properties. EFAs and their metabolites lower serum cholesterol, triglycerides and blood pressure. EFAs appear to be of benefit in atopic eczema, premenstrual syndrome, psoriasis, auto-immune disorders especially rheumatoid arthritis and systemic lupus erythematosus, prevention of target organ damage in diabetes mellitus, peptic ulcer disease, ulcerative colitis, coronary heart disease and atherosclerosis. EFAs and their metabolites can selectively kill tumor cells both in vitro and in vivo without harming normal cells. In addition, EFAs seem to play a fundamental role in inflammation and immune response. In view of their actions and relative safety, it is anticipated that EFAs may be useful in the management of several diseases.
