Eating foods with artificial trans fats, like some fried or baked goods, is linked to higher bad cholesterol in people on tightly controlled diets.

Scientific Claim

Higher dietary intake of trans fatty acids (TFA) is associated with higher levels of low-density lipoprotein cholesterol (LDL-C) in controlled feeding studies.

Original Statement

“Higher intakes of SFA, dietary cholesterol and TFA were each significantly associated with higher LDL-C levels”

From study:Abstract 18256: Importance of Controlling Dietary Intake of Saturated Fat for Prevention of Coronary Heart Disease: Lessons From the Metabolic Ward Studies

Systematic Review With Meta-Analysis

Human

This study found that eating more trans fats raises your 'bad' cholesterol (LDL-C), just like the claim says — even though other fats like saturated fat have an even bigger effect.

Eating more healthy fats like those in nuts, seeds, and fish is linked to lower bad cholesterol in people on controlled diets.

78%

People who eat a lot of trans fats (like in fried or processed foods) are more likely to have heart problems than those who eat very little.

77%

Swapping 2% of your diet’s bad fats (trans fats) for healthy oils like soybean or corn oil lowers your cholesterol ratio more than swapping them for bread or pasta.
