DLM: Trans-fatty Acids (2010)
What effect does consuming natural (ruminant) vs. synthetic (industrially hydrogenated) trans fatty acids have on LDL-, HDL- and non-HDL cholesterol? (NEL)
The ADA Disorders of Lipid Metabolism workgroup concurs with the following statement and grade from the USDA Nutrition Evidence Library (NEL):
Limited evidence is available to support a substantial biological difference in the detrimental effects of industrial trans fatty acids (iTFA) and ruminant trans fatty acids (rTFA) on health when rTFA is consumed at seven to ten times the normal level of consumption.
- Grade I means there is Good/Strong evidence supporting the statement;
- Grade II is Fair;
- Grade III is Limited/Weak;
- Grade IV is Expert Opinion Only;
- Grade V is Not Assignable.
