Poor American eaters! You know how transfat is, like, going to totally kill you or something and that's why it's been snatched from all of our food? Well, there's one small problem: An ideal replacement fat hasn't really been identified; most of the fats being used in replacement (palm kernel oil, palm oil, coconut oil) are actually higher in saturated fat, thus not exactly making your snack foods any "healthier." Which means our country is destined to wallow in obesity until everyone starts following the Alice Waters-whole-seasonal-foods mantra. [WSJ]
