Mustard and Ketchup
Yes, the great American condiments contain added sugar! A serving of ketchup (one tablespoon) contains 3.4 grams of sugar and mustard contains from 1 gram (regular mustards) to 8 grams per serving (for honey mustard). Barbecue sauce is even worse—check the labels. Our search found it ranges from 8 to 13 grams of sugar per tablespoon.
