As for Heinz, my impression has always been that it’s the standard, mass-produced supermarket fare that is probably not healthy/natural. Nothing they make that much of that lasts for so long can possibly be so.
Boiling kills most bacteria. Acid kills the leftover Botulism spores (one of the few diseases that survive boiling). Seal while hot and the food can stay good for a year or longer.
Tomatoes already are near the acid point that kills botulism. Just gotta lower pH a little more with either lemons or vinegar. And bam, success.
A professional would need to measure the pH to be sure as acidity levels differ. But we've been canning tomatoes for nearly two centuries now, the science is well tested and well figured out.
> Nothing they make that much of that lasts for so long can possibly be so.
Refrigeration was invented long after preserved foods. You couldn't match a Roman Legion 500 miles without preservatives.
Salt, olive oil and wheat. It must have sucked to be a Roman Legion but less so than other troops.
It's why 1lb of salt was worth 1lb of gold back then. The secrets of long lasting food (fermentation, salt, and other methods) is millennia old. Canning is relatively new (boiling+sealing simultaneously), a 1800s era discovery. But canning's health effects are well studied.
EDIT: Deleted my previous comment.
EDIT: I seem to have gotten the story backwards. It was West-Africa who needed the salt, but they had so many gold-mines that Gold was near worthless. Woops!!
So any European who brought salt past the Sahara Desert could trade 1-lb of salt for 1-lb of gold.
However salt was more expensive than today. But measured in eg hours of the average person had to work for to afford something, almost everything is cheaper today than almost any time in the past. Especially goods. (Services or land, not so much.)
I guess it help to start with a non-rhotic accent.
Going off on a tangent: I was very confused when one Calvin and Hobbes comic rhyme 'macabre' with 'job'; I figured out later that it's because American accents are weird.
(UK) IPA(key): /ˌməˈkɑː.bɹə/, /ˌməˈkɑː.bə(ɹ)/
(US) IPA(key): /məˈkɑb/, /ˌməˈkɑ.bɹə/, /ˌməˈkɑ.bɚ/
Not rhotic, plus the vowel in "sauce" tends towards "or" rather than "ah". Hope that's a comprehensible explanation of our esoteric pronunciation :)
I think the rhyming slang part comes from Cockney slang my Dad always used to say "Dogs Eye and Dead Horse" to mean Meat Pie and Tomato Sauce.
He had other strange slang he'd use too like "Oxford Scholar" to mean "One Dollar" - UK uses pounds though so no idea where that one originated...
What is the American pronunciation of Sauce? If I had to guess maybe they pronounce it so it sounds like "Sores" or "Saws".
I don't know if I've ever heard an American say Sauce. On most American tv shows they talk about 'Ketchup'. Eg Hot Dog and Ketchup, which is a Frankfurt with Tomato sauce on a bun (doesn't really have the same ring...).

That's 100% spot on.
I'm in the northeastern area of the country, it may be different for other areas.
Where I come from, it’s more like “sos” or I think “sas” in IPA.
Most often like “saws” (the cutting tools would be “sawz”)
