To evaluate the physiological mechanisms and practical dietary balance of n-6 and n-3 fatty acids required to protect against coronary heart disease.
Synthesized findings from published epidemiological investigations and clinical trials evaluating polyunsaturated fatty acid consumption.
Assessed distinct metabolic pathways of linoleic acid, linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid on lipid profiles, vascular function, and cardiac rhythm.
Linoleic acid regulates low-density lipoprotein cholesterol by decreasing its synthesis and enhancing clearance, while mitigating the hyperlipemic effects of saturated fats, trans fats, and dietary cholesterol.
Eicosapentaenoic acid and docosahexaenoic acid act as antiarrhythmic agents, enhance vascular endothelial function, and decrease blood pressure, platelet sensitivity, and circulating triglycerides.
Consuming approximately 6% of energy as linoleic acid, 0.75% as linolenic acid, and 0.25% as eicosapentaenoic plus docosahexaenoic acid provides a cardioprotective ~6:1 ratio, though absolute mass consumed remains the primary determinant of benefit.

Implication

Review demonstrates complementary cardioprotective roles of dietary omega-6 and omega-3 fatty acids in healthy adults, suggesting absolute intake matters more than their ratio.
