We're not sure why our parents fed us so much of this stuff when we were kids - it's so unhealthy! Just like the multi-colored cereal we talked about, you really only have to look at boxed mac & cheese to know it's not going to do you any good. And we like to use the term 'cheese' very loosely when it comes to this stuff! A proper serving of Kraft's Mac & Cheese can cost you up to half of your daily recommended sodium intake.
Unless you want to hook yourself up with some high blood pressure, hypertension, or other sodium-related ailments, we'd advise steering clear of the old mac & cheese. Try making whole grain pasta with real, grated parmesan on top. You can even add a little pesto to make it fancy if you like.
