How do omega-3 fatty acids affect lipid levels?

Omega-3 fatty acids are known to significantly lower triglyceride levels in the blood, which is a key factor in cardiovascular health. When consumed, omega-3 fatty acids interact with various enzymes and cellular pathways that regulate triglyceride synthesis and metabolism in the liver. This leads to a decrease in liver triglyceride production and an increase in the clearance of triglyceride-rich lipoproteins from circulation.

Additionally, while omega-3 fatty acids are less effective at lowering LDL (low-density lipoprotein) cholesterol, they do not generally result in an increase in LDL levels and may even help improve overall lipid profiles. Hence, their primary action is the reduction of triglycerides, making them particularly beneficial in managing dyslipidemia and reducing cardiovascular risk. The other options do not accurately reflect the well-established effects of omega-3 fatty acids on lipid levels.
