DLM-SF: Sources of Satured Fat Summary Tables (2021)

DLM-SF: Sources of Satured Fat Summary Tables (2021)

The following tables are visual representations of evidence from systematic reviews that evaluated sources of saturated fat intake. Table 1 is a visual representation of evidence from an overview of systematic reviews that evaluated the association of saturated fat food sources and cerebral vascular accidents, coronary heart disease, and all-cause mortality. Table 2 is a summary of results from systematic reviews of randomized controlled trials that evaluated the effect of different saturated fat food sources on cardiovascular risk factors and blood lipids. Table 3 is a summary of results from an overview of systematic reviews on meat intake and association with morbidity and mortality. Systematic reviews were not limited to meat and dairy; however, most available evidence on sources of saturated fat evaluated meat and dairy. Additional information can be found on the Sources of Saturated Fat Systematic Review page.
