Here's what a standard serving size of each of your favorite snacks looks like

When's the last time you ate just two Oreos?

Yeah. Me neither. Yet that is the standard Food and Drug Administration serving size listed on the back of the package. In other words, eating two of these cookies will give you the caloric equivalent of a standard snack — 140 calories, or about the same as:

• Two apples
• One piece of (lightly) buttered toast
• 10 cups of spinach

In May the FDA announced that it was updating these serving sizes, or, in agency parlance, "reference amounts customarily consumed per eating occasion," so that they would better reflect how much of each item people actually eat. Those changes go into effect in summer 2018.

Read on to see what the standard serving sizes of your other favorite foods look like now:
