1 cup of black beans = One slice of Carvel Celebration ice cream cake
Beans are filling for a reason: one (cooked) cup comes out to about 227 calories. You know what else is that caloric? A slice of the Carvel Celebration ice cream cake you can find in most grocery stores. Though the incredibly clever "Happy Bird-Day" message you frosted on top probably adds an extra 10.
One glass of orange juice = 12 Pringles
OJ has a lot of great things like calcium and vitamin C, but it also doesn't skimp on the calories. Each glass is 120 calories, making one as calorie-rich as a small stack of Pringles -- and the Tropicana orange doesn't have nearly as great a mustache as Julius Pringles. So low marks all around.
1 cup of granola = Two bags of M&M's
If you had to filter the ingredients in trail mix by calories, you'd probably put the chopped M&M's in the top tier and the granola in the bottom, right? Wrong. While granola can obviously vary, a cup of brands like Bear Naked has 480 calories, which is the same as two whole bags of M&M's. And since you already know the truth about another common trail mix ingredient (almonds), you might as well just skip the mix and go straight for the candy.
