Before 1974 the only regulations involving stearic acid were for its u
se as a food additive. In 1974 the regulation for fat, fatty acid, and
cholesterol contents was finalized; this regulation defined saturated
fatty acid as the sum of lauric, myristic, palmitic, and stearic acid
s. Because the labeling of saturated fatty acid was voluntary except w
hen a claim was made for fat content, the inclusion of stearic acid in
that definition had little impact on foods high in fatty acids. Under
the requirements of the Nutrition Labeling and Education Act (NLEA) o
f 1990, the definition of a saturated fatty acid gained major signific
ance, with ties to mandatory nutrition labeling, nutrient content clai
ms, and health claims. It was requested that stearic acid be dropped f
rom the definition of a saturated fatty acid because it did not raise
blood cholesterol concentrations. Scientific data demonstrating the la
ck of involvement of stearic acid consumption in negative health effec
ts are needed.
