Assessment of dietary intakes of total fat and fatty acids for residents in China in 2015–2018

The contents of 62 fatty acids, including saturated fatty acids (SFA) and trans fatty acids (TFA) in 192 composites from the 6th (2015–2018) Chinese Total Diet Study (TDS) were determined using gas chromatography (GC) with flame ionization detector (FID). The contents of total fat, SFA, and TFA varied greatly among various food categories with meats recording the highest level. The TFA intake for adult males was 0.19 ± 0.10 percentage of total energy intake (% E) within an range of 0.08−0.42% E, which was lower than the maximum (1% E) recommended by the World Health Organization (WHO), while the intakes of total fat and SFA were 29.51 ± 6.01 % E and 7.01 ± 1.95 % E respectively. Comparing to the 5th Chinese TDS, the intakes of SFA and TFA, which were statistically significant, had been reduced by 8.1 % and 30.18 %, indicating the dietary variations for Chinese.
