Intersterified Oils: The New Trans Fats?
We have known for many years that trans fats increase risk for heart attacks and some cancers. Laws requiring trans fats or partially hydrogenated oils to be listed on nutrition labels went into effect last year, so food manufacturers are finally eliminating them from their products. One substitute that is appearing in some foods is a new type of fat made with a process called interesterification or fatty acid randomization. Interesterified oils have saturated fatty acids, usually from plants, inserted into other vegetable oils. A study from Brandeis University shows that both interesterified fats and partially hydrogenated oils raise the bad LDL and lower the good HDL cholesterol much more than the plant saturated fats found in palm, palm kernel and coconut oils.
