The WHO estimates that foods containing trans fats are the cause of 500,000 premature deaths worldwide every year by contributing to heart disease and heart attacks.
The organisation is asking all governments to use its REPLACE action plan to swap trans fats for healthier options, which it says will not affect the taste or cost of food.
In a dramatic move that has only been reserved for saving the public from communicable diseases in the past, the World Health Organization has called for a world-wide ban on trans fats in the next five years.

Experts say transitioning away from trans fats is not only life-saving, but financially viable as well. They are often present in frying oils, fried snacks, margarine and shortening since trans fat-based oils have a longer shelf life (don't worry, Canada has almost phased them out entirely in those products).
The six-step guide, called REPLACE, comes after World Health Organization opened a consultation until 1 June to review draft guidelines on intake of trans-fats and saturated fats for adults and children.
Trans fats should be less than 1 per cent of the total count (less than 2.2gm per day in a 2,000 calorie); both fats must be replaced by polyunsaturated fatty acids and monounsaturated fat.
Artificial trans fat or trans-fatty acids are produced in a process that adds hydrogen to liquid vegetable oils to make them more solid. This is because they're used in partially-hydrogenated oils, which were first used as a butter replacement and then later as a replacement for foods containing saturated fatty acids. Partially hydrogenated oils are primarily used for deep frying and as an ingredient in baked goods.More news: Next Chelsea manager: Newcastle boss Rafa Benitez discusses Blues target
But studies gradually revealed that trans fats wreck cholesterol levels in the blood and drive up the risk of heart disease. Diets high in trans fat increase heart disease risk by 21 per cent and deaths by 28 per cent.
REPLACE urges countries to assess and monitor trans fats consumption, establish laws to stamp out trans fats and raises awareness of their risk.
"A comprehensive approach to tobacco control allowed us to make more progress globally over the last decade than nearly anyone thought possible", he said, "Now, a similar approach to trans fat can help us make that kind of progress against cardiovascular disease, another of the world's leading causes of preventable death". "In addition, there are indications that trans fat may increase inflammation and endothelial dysfunction".More news: WhatsApp's latest update brings more order and control to group chats
