Abbreviations: SFA (%) the percentage of total energy intake from saturated fatty acids, PUFA (%) the percentage of total energy intake from polyunsaturated fatty acids, P:S the ratio of polyunsaturated fatty acid intake to saturated fatty acid intake

^aRCOT did not report either SFA or PUFA intake or the P:S ratio. However, the corn oil group reported consuming an average of 64 g of corn oil and 2070 kcal per day [21], so the corn oil alone would provide approximately 35.0 g of PUFA [88] or 15.2% of total energy intake from PUFA [21]. ^bODHS only reported data on dietary intakes from 17 “especially conscientious” participants in the experimental group and from none of the participants in the control group [22]. ^cThe values for NDHS come from a weighted average of the experimental and control groups respectively. ^dMRCT did not report SFA or PUFA intake for either group. However, the experimental group reported consuming an average of 80 g of soybean oil and 2380 kcal per day, so the soybean oil alone would provide approximately 46.2 g of PUFA [88] or 17.5% of total energy intake from PUFA
