fats used to replace trans fats are dangerous

Trans fats have gained a bad name because of their detrimental effects
on cardiovascular health and have been in the news because of the
actions of New York City and other US cities, which are banning them
from restaurant foods.

An industry response has been the development of so-called inter-
esterified fats (since you can't fry or make pastry without fat). Such
fats are typically made by first rearranging the location of fatty
acids on a natural fat (usually soybean oil) with enzymes, then
blending with naturally occurring saturated and unsaturated fats to
produce the desired consistency. One such a product is called
Novolipid®.

These fats are devoid of trans-fatty acids, which are so common in
hydrogenated ("hardened") fats. But studies performed over a mere four
weeks have found that use of such replacement fats by 30 healthy
adults produced a reduction in HDL "good" cholesterol levels and,
worse, a 20% rise in blood glucose level. The glucose effect was
traced to a fall in insulin action. The fats compared were palm oil
(saturated), partially hydrogenated soybean oil (containing trans-
fats), or inter-esterified soybean oil.

It appears it may be necessary to think again about this technological
fix. A buch better solution might be to change the food formulation so
natural fats can be used.
