New study finds corn oil superior to extra virgin olive oil in lowering cholesterol Plant sterols naturally found in corn oil linked to heart health benefits WASHINGTON, December 6, 2013 – Corn oil significantly reduces cholesterol with more favorable changes in total cholesterol (TC) and LDL-C than extra virgin olive oil, new research shows. The findings were presented today at the American Society for Nutrition's Advances & Controversies in Clinical Nutrition Conference by lead researcher, Dr. Kevin C Maki, PhD, of Biofortis, the clinical research arm of Mérieux NutriSciences.

Among the 54 healthy men and women in the feeding study, consumption of foods made with corn oil resulted in significantly lower levels of LDL (bad) cholesterol and total cholesterol than the same foods made with extra virgin olive oil. Corn oil lowered LDL cholesterol by 10.9 percent compared to extra virgin olive oil's 3.5 percent reduction1,2, and total cholesterol decreased by 8.2 percent with corn oil compared to 1.8 percent for extra virgin olive oil.2 Study participants received four tablespoons of corn oil or extra virgin olive oil in the foods provided every day, consistent with the Dietary Guidelines for Americans recommendations. All foods were provided to the study participants as part of a weight maintenance diet. The randomized, double-blind, controlled crossover clinical trial assessed the effects of dietary oils on fasting lipoprotein lipids. The study compared the effects of corn and extra virgin olive oil on LDL cholesterol (primary outcome variable), total cholesterol, HDL cholesterol (good cholesterol), Non-HDL cholesterol, Triglycerides and the total to HDL cholesterol ratio. Study participants had fasting LDL cholesterol ≥130 mg/dL and END
