We all love a bit of cake from time to time, and that's totally fine. We're not about to tell you to give up a slice of birthday cake because it might give you cancer. However, if you bake regularly with cake mixes, it might be time to reexamine those choices. Baking from scratch with healthier flour than refined white flour is a good alternative or you could just cut down in general. Either way, it's definitely time to give up the cake mix.
The sneaky thing about commercial cake mixes is that they contain low volumes of trans fats, which they're not legally required to disclose on the label. So, if you're baking a lot, it could all be adding up in your arteries. If you add frosting on top, it's going to be even worse.
