Ketchup also has a lot of high fructose corn syrup in it. Avoid it like the poison it is.
err… not all ketchups. Annies, and Heinz BOTH make organic variants that also happen to avoid the HFCS you seem to think is poison. you should go look for that!
More importantly, where can I get that ketchup dispenser in the picture? That would be great at family gatherings.
Wow. I’m one of 3%.
I keep my ketchup, unrefridgerated, well over a month. More like several months. Tastes perfectly fine to me.
And what might it suggest to you, that something lasts for the better part of a hundred days and not even bacteria will grow upon it?

The same is true about my daily multi-vitamin.
