Abstract Trans-fatty acid (TFA) elimination from global food supply is a 2023 World Health Organization target. Brazil adopted the limit for TFA at 2 g/100 g fat to be implemented by 2023. This work aimed to evaluate the fat profile of about 600 industrialized products from Sao Paulo state, Brazil, between 2005 and 2018. The total fat (TF) was determined by gravimetric methods and the fatty acids by gas chromatography. The mean contents of TFA were higher than 2 g/100 g fat in 30% of samples (bakery products, potato chips, snacks, hamburgers, margarine, and spread). The highest mean content was verified in biscuits: cassava and salty (20.5 and 7.1 g/100 g fat). TFA mean contents evaluated over time decrease in sweet biscuit (4.9 to 1.2), potato chips (4.2 to 1.8), soybean oil (2.1 to 1.2), and canola oil (3.5 to 0.7) (g/100 g fat), whereas saturated and mainly polyunsaturated fatty acids in sweet biscuits and potato chips increased. Palm and polyunsaturated oils and interesterified fat have been used to avoid partially hydrogenated oils. Continuous monitoring of foods is essential to help in both government and corporate actions in adapting their products and meeting current regulatory restrictions on the content of TFA.
