Tolerable Upper Intake Levels For Trans Fat, Saturated Fat, And Cholesterol, Nutrition Reviews, May 2011
The IOM [Institute of Medicine, develops RDAs] did not set ULs [upper intake limits] for trans fat, saturated fat, and cholesterol because any intake level above 0% of energy increased LDL cholesterol concentration.
The results of this analysis confirm the limitations of the risk assessment model for setting ULs because of its inability to identify a UL for food components, such as cholesterol, that lack an intake threshold associated with increased chronic disease risk.
So, the optimal intake for trans fat, saturated fat, and cholesterol is, by this analysis, zero. Any amount above zero raises LDL cholesterol and disease risk.
