A type of unsaturated fat with a specific molecular shape (the trans configuration), most often created when liquid oils are partially hydrogenated for texture and shelf life, though small amounts occur naturally in the fat of ruminant animals like cattle and sheep.

Why it’s used

It is not taken deliberately for a benefit; it appears on a label as a disclosed component of the total fat content, either from the food source itself or from processing.

What the evidence is for

raising LDL cholesterol and cardiovascular disease risk with regular intake.

What the evidence says

The link between trans fat intake and cardiovascular risk is one of the more settled findings in nutrition science. Regulatory bodies including the FDA and the World Health Organization cite it as a basis for removing industrially produced trans fat from the food supply. This is evidence about a risk association, not about any intended effect of taking it.

Context

Industrially produced trans fat (from partial hydrogenation) has been the primary regulatory target; naturally occurring trans fat in dairy and meat fat is present in much smaller amounts and has been studied separately.
