When it comes to healthy eating, artificial trans-fats have become the new bogeyman as they raise bad cholesterol levels and lower the good ones. But according to a new study in the journal Nutrition and Metabolism, replacing trans-fats with a safer alternative might not be so easy since one of the main replacements, so-called interesterified oils, may have even bigger problems of their own. In a study of 30 healthy volunteers, researchers found that not only do these new oils lower healthy HDL levels, but also cause a significant rise in blood sugar, since they can affect the body’s insulin levels. Sounds like continued heartache for researchers, as they try to find the best, heart-healthy foods.
