Following (and indeed, likely due in no small part because of) the trans fat crusade, the next “bad fat” will likely be the interesterified fat resulting from total hydrogenation. Total hydrogenation, unlike partial hydrogenation, produces no trans fats. However, the resulting fatty acid is saturated and, worse, seems to cause a sharp rise in blood sugar. Given that the so-called “metabolic syndrome” consists of hypertension, obesity, and diabetes, it stands to reason that, should these fats become popular, the cause of this syndrome will eventually be laid in no small part at the feet of the interesterification process.
