Good to Know
When you buy them, English (hothouse) cucumbers and the small Persian ones have thinner skins and fewer seeds, so you can skip peeling and keep the bit of fiber that gets you to 0.6g per cup. Watch the prepared stuff: store deli cucumber salads and most pickle relishes are sweetened, and bread-and-butter pickles in particular can run several grams of added sugar per serving. Dill pickles and plain sliced cukes stay close to the 3.2g net carbs here, but check the label on anything labeled "sweet" or "gherkin."
