Interesterification modifies the melting and crystallization behaviour of the fat, thus producing fats with the desirable physical properties of trans fats but without trans FA.
In addition, because of its effects on metabolism of gamma-linolenic acid and arachidonic acid, trans fatty acids intake can affect the metabolism of prostaglandins and other eicosanoid and thus alter platelet aggregation and vascular function.

Such alteration is paralleled in studies in humans by decreased rates of LDL apoB catabolism, reductions in the size of LDL cholesterol particles, increased rates of apo A-I catabolism, and changes in acieos lipid levels.

On the other hand, metabolic studies have clearly shown that trans fatty acids increase LDL cholesterol and reduce HDL cholesterol. N Engl J Med ; One of the most important studies in this regard was conducted by Mensink et al.
Since it has been shown that t FA cross the placental barrier and they are in breast milk, these sources should be considered, especially if pregnant women or nursing mothers are consuming foods rich in t FA.
