The first time I tried ketchup after strictly avoiding added sugars for several weeks was a WILD experience. It tasted sweeter than maple syrup. I used to douse my food in ketchup and now I can't even eat it on fries because it's so sickeningly sweet. I noticed the same with most bottled salad dressings and sauces (barbecue sauce and honey mustard being even more egregious than ketchup).
