'Redo your pantry' is an important section in the linked article. My wife is really good about finding pointing out sugar in sauces that seem healthy [1], tomato sauce, catsup, etc., and finding sure free alternatives [1] https://www.prevention.com/food/healthy-eating-tips/10-hidde...
I was sad to learn that sauces like ketchup are mostly sugar. Even sriracha is quite sugary.
I don't know if this is because sugary sauces become popular, or because popular sauces were adulterated with sugar.
