title: Substituting enzymatically interesterified butter for native butter has no effect on lipemia or lipoproteinemia in Man.
abstract: The aim of this study was to determine whether substituting enzymatically interesterified butter for native butter in the usual diet affects lipid and lipoprotein levels in man. Parameters studied were serum total cholesterol, LDL-cholesterol, HDL-cholesterol, free cholesterol, phospholipids, triglycerides, apoA1 and apoB and the fatty acid composition of serum triglycerides, free fatty acids, phospholipids and cholesterol esters. Subjects were healthy volunteers and a controlled design was used. The only mathematically significant difference found when interesterified butter was substituted for butter was an about 7% lower fraction of oleic acid in the serum cholesterol esters (p = 0.005). In contrast to an earlier study where chemically interesterified butter fat was substituted for native butter, no indications are found in this study that replacing native butter by enzymatically interesterified butter, in amounts normally consumed, may have any beneficial effect on health.
