People who eat more trans fats—especially from processed foods—are more likely to die from any cause, including heart disease and cancer.

Scientific Claim

Higher intake of total trans fats is associated with a 34% increased risk of all-cause mortality in adults, primarily driven by industrial sources, with moderate certainty of evidence from prospective cohort studies.

Original Statement

“Total trans fat intake was associated with all cause mortality (1.34, 1.16 to 1.56)... industrial, but not ruminant, trans fats were associated with CHD mortality... the association seems to be most consistently driven by industrially produced trans fats.”

Assessment Explanation

The claim correctly uses 'associated with' and reflects the study’s conclusion that industrial trans fats drive this risk. The authors explicitly avoid causal language and note the moderate certainty level.

Systematic Review With Meta-Analysis

Human

This study found that people who ate more artificial trans fats (like those in fried and baked goods) had a 34% higher chance of dying from any cause, and this was mostly because of industrial fats—not natural ones from animals.

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.

Eating more fat in your diet doesn't seem to make you more likely to die from heart disease, according to long-term studies of nearly 90,000 people.

79%

Eating more saturated fat from meat, butter, or cheese doesn’t clearly make people more likely to die early or get heart disease or diabetes, but the science isn’t strong enough to be sure.

Eating more saturated fat — like in butter or red meat — doesn't appear to raise the chance of dying from heart disease, based on long-term studies of nearly 90,000 people.
