Trans Fats: Just Avoid

Trans fats are an industrial creation, the result of partially hydrogenating vegetable oils to make them solid at room temperature. Unlike every other dietary fat, they offer no metabolic benefit and a long list of confirmed harms, including a measurable increase in cardiovascular disease risk at any meaningful intake.

Many countries now ban or severely restrict their use, which has dramatically reduced exposure compared to a decade ago. They still hide in older formulations of margarine, certain baked goods, fried foods at low-cost restaurants, and some non-dairy creamers. The label words to scan for are partially hydrogenated.

This is the single dietary recommendation that admits no nuance. There is no daily value, no minimum effective dose, no context in which they are useful. Read labels, avoid them, and that is the entire intervention. Skip the foods that contain them, and you have already addressed the only fat worth being absolute about.
