It's time to stop hogging on chips and pan cakes, as a new study reveals that people who eat trans fat could face a greater risk of coronary heart disease.
Researchers in Canada analysed the results of observational studies and assessed the association between saturated and trans fats and health outcomes in adults.
Saturated fats come mainly from animal products, such as butter, cows' milk, meat, salmon and egg yolks, and some plant products such as chocolate and palm oils, while trans fats are mainly produced industrially from plant oils for use in margarine, snack foods and packaged baked goods.
The team found no clear association between higher intake of saturated fats and all cause mortality, coronary heart disease (CHD), cardiovascular disease (CVD), ischemic stroke or type 2 diabetes, but could not, with confidence, rule out increased risk for CHD death.
They did not find evidence that diets higher in saturated fat reduce cardiovascular risk.

Meanwhile, consumption of industrial trans fats was associated with a 34 prevent increase in all cause mortality, a 28 percent increased risk of CHD mortality, and a 21 percent increase in the risk of CHD.
The researchers concluded that dietary guidelines for saturated and trans fatty acids must carefully consider the effect of replacement nutrients.
The study is published in the journal BMJ.
