Good to Know
Cherry and grape tomatoes carry slightly more sugar per bite, so count them if you graze on a handful. Watch the processed stuff: canned tomato sauce and ketchup often hide added sugar, and a single tablespoon of standard ketchup can run about 4 g of carbs, more than a whole fresh tomato. Sun-dried tomatoes concentrate the sugars too, so a small jarred portion adds up faster than you might expect.
