Trans fat
Unlike other dietary fats, trans fatty acids are not essential and provide no known benefit to human health. As with saturated fatty acids, there is a positive linear trend between trans fatty acid intake and LDL cholesterol concentration, and therefore increased risk of coronary heart disease,[23][38] by raising levels of LDL cholesterol and lowering levels of HDL cholesterol.[39]
Several large studies have indicated a link between consumption of high amounts of trans fat and coronary heart disease, and possibly some other diseases,[29][40][41][42] prompting a number of government health agencies across the world to recommend that the intake of trans-fats be minimized.
In the US, partial hydrogenation is common as a result of preference for homegrown oils. However, since the mid-1990s, many countries around the world have started to move away from using partially hydrogenated oils.[43] This led to the production of new margarine varieties that contain less or no trans fat.[44]
