The Claim

Replacing dietary monounsaturated fats with omega-6 polyunsaturated fats reduces apolipoprotein B concentrations by approximately 35% in healthy men, whereas saturated fat intake results in a smaller reduction, indicating that fatty acid composition influences the production or clearance of atherogenic lipoprotein particles.

Cause and effect
1 study reviewed
In plain English

Replacing monounsaturated fats with omega-6 polyunsaturated fats in the diet lowers apolipoprotein B levels by about 35% in healthy men, while saturated fats cause a smaller decrease, showing that the type of dietary fat affects the amount of atherogenic lipoprotein particles in the blood.

Why this might work

When omega-6 fats replace other fats in the diet, the liver makes less of the protein that holds bad cholesterol particles together, and it clears those particles from the blood faster.

  1. Study: Effects of saturated, monounsaturated, and omega-6 polyunsaturated fatty acids on plasma lipids, lipoproteins, and apoproteins in humans.

    When healthy men ate more omega-6 fats (like sunflower oil) instead of monounsaturated fats (like olive oil) or saturated fats (like butter), their levels of a harmful blood protein called ApoB dropped the most — showing that the type of fat you eat really does affect how many bad cholesterol particles are in your blood.
