Best-practices policies towards this goal follow specific criteria established by WHO and limit industrially produced trans fat in all settings.

Alternatives include limiting trans fat to two grammes per 100 grammes of total fat in all foods, and mandatory national bans on the production or use of partially hydrogenated oils – a major source of trans fat – as an ingredient in foods.

Currently, nine of the 16 countries with the highest estimated proportion of coronary heart disease deaths caused by trans fat intake do not have a best-practice policy.
