Selected foods sampled from Australian supermarkets and fast food outlets were analyzed for trans fat (TF) content. The product with the highest amount of TF (6.3 g/100 g product) was a household shortening. The TF contents in spreads were remarkably low (average 0.5, range 0.2–1.3 g/100 g product) with only 3 out of 15 exceeding the maximum level (2.0 g/100 g fat) permitted in Denmark. Ready-to-eat French fries purchased from all but one (1.5 g/100 g product) fast food outlet contained generally low levels of TF (average 0.4, range 0.3–0.7 g/100 g product), and the majority of the outlets appeared to have used non-hydrogenated vegetable oils for frying. Frozen French fries and ready-to-eat potato chips purchased from supermarkets were also low in TF (average 0.1 and 0.2 g/100 g product, respectively). So were the bakery products (biscuits, cakes, bread, cake and muffin mixes) except for croissants. However, 9 out of the 103 products tested would have been prohibited from sale in Denmark, while 25 and 12 products would have failed to qualify for ‘trans fat-free’ claims according to the mandatory labeling regulations currently in force in Canada the USA, respectively.
