WHO developed a global laboratory protocol for measuring trans fat in foods

WHO’s new laboratory protocol entitled "Global protocol for measuring fatty acid profiles of foods with emphasis on monitoring trans fats originated from partially hydrogenated oils" provides a globally harmonized method to measure trans fats in foods. It will enable countries to assess the levels of trans-fatty acids (TFA) in their food supply to understand key sources of TFA in their diet as well as to monitor the compliance or effectiveness of the policy implemented to eliminate industrially produced TFA.
