Corn oil better at cutting cholesterol than extra virgin olive oil

Washington –  Researchers have shown that corn oil significantly lowers cholesterol with more favorable changes in total cholesterol (TC) and LDL-C than extra virgin olive oil.

The scientists were led by lead researcher, Dr. Kevin C Maki, PhD, of Biofortis, the clinical research arm of Merieux 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.

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 less than 200 mg/dL.
