Trans-fatty Acids

The elimination of industrially produced trans fatty acids (IP-TFA) is recommended by the World Health Organization (WHO) and the Pan American Health Organization (PAHO) to prevent non communicable diseases, such as coronary heart disease.

Increased intake of trans fat (>1% of total energy intake) is associated with increased risk of coronary heart disease mortality and events. Trans-fatty acids (TFA) intake is responsible for more than 500,000 premature deaths from coronary heart disease each year around the world.

The elimination of trans fats from the food supply is feasible through policy approaches, including the use of legislative or regulatory measures to limit IP-TFA to no more than 2 grams/100 grams (2%) of total fat in all food products; ban partially hydrogenated oils, the major source of IP-TFA; and/or a combination of the two policies aforementioned.

Key facts
  • French fries being deep fried in oil and scooped with a ladle
    Industrially-produced trans fat is a man-made harmful compound found in foods, fats and oils.
  • Trans fat clogs arteries and increases the risk of coronary heart disease.
  • Increased intake of trans fat (>1% of total energy intake) is associated with increased risk of coronary heart disease mortality and events.
  • Eliminating trans fat from the food supply and replacing it with healthier alternatives is feasible and is happening in many high-income countries.

Globally, the best available estimate using a comprehensive analytic approach suggests that in 2010, 537,000 deaths from CHD were attributable to TFA intake; of these, 160,000 occurred in the Region of the Americas, 45% prematurely.
Fact sheet

An extensive body of evidence has demonstrated the negative metabolic effects of TFA, as well as the association between total TFA intake and CHD. High TFA intake significantly increases the risk of death from any cause by 34%, the risk of CHD death by 28%, and the risk of CHD occurrence by 21%. Non-significant increases of 7% for ischemic stroke and 10% for diabetes were also noted. TFA increases low-density lipoprotein (LDL) cholesterol levels, the most harmful type, while lowering beneficial high-density lipoprotein (HDL) cholesterol levels, to an even greater extent than saturated fats.

PAHO Response

PAHO has launched the Plan of Action for the Elimination of Industrially Produced Trans-Fatty Acids 2020-2025. It intends to provide guidance and monitoring to PAHO Member States in the elimination of industrially produced trans-fatty acids. PAHO is also launching a virtual course on the WHO REPLACE action package to eliminate IP-TFA to advance on the Regional nutrition agenda and country capacity building on the strategies of eliminating IP-TFA from the food supply under the PAHO Plan of Action for the Elimination of IP-TFA.
