I have heard ketchup is loaded with high fructose corn syrup aka sugar and one reasons kids plaster it on everything may be they are hooked on sugar, hence fat and diabetic

Yup. All that sugar is why you don’t even have to refrigerate an open bottle of ketchup. kind of weird. If bacteria won’t grow in it, how nourishing can it be?
Um... you don’t keep your ketchup in the fridge? Yikes.
I would say that it is the acidity from the tomatoes and vinegar more than the sugar that inhibits bacterial growth. It will not inhibit mold growth. Sugar is after tomato concentrate and vinegar on the ingredient list; ingredients are listed in order of quantity, starting with the highest quantity.
I just looked at pictures of ketchup bottles on line. They all say to refrigerate after opening.
“If bacteria won’t grow in it...”
Wow. Didn’t know that. Definitely worth noting.
