Duplicate meals were collected from 20 children each in Hong Kong and Jiangmen for chemical analysis of fat intake and fatty acid profile. Results showed daily fat intake was 34.7 g for children in Jiangmen, which was about 30% lower than that in Hong Kong (47.6 g). Fatty acid profile in the diet of Jiangmen children showed a significantly higher polyunsaturated fatty acid saturated fatty acid ratio (0.81 vs 0.69) and linoleic acid/myristic acid ratio (20.73 vs 10.91) than that of Hong Kong children.
