No. They're doing it because it's marginally cheaper and more convenient in the aggregate, but if they didn't and stuck to cane sugar, the practical difference on the consumer side in terms of consumption and price per product would be essentially nil or close enough not to matter.
It's not about displacing other sugars. It's a cheap substitute for things not sugar. The argument about corn syrup is misplaced, it should be about sugars in general in US processed food. But corn syrup just happened to be that sugar.
No, ostensibly it's cheaper at scale. But from a consumer's perspective, it doesn't matter that they're using that instead of sugar. There's a much larger conversation to be had about the misinformation surrounding sugar and carbohydrates, but anyways..
If the actual total sugar (or sugarlike) content decreased along with the corn syrup, there definitely would be differences.
Ask anyone who's visited the US about how the food tastes. It's not just that serving portions are much bigger, but everything just tastes sweeter too. I've had people tell me they visited the states and even the plain white bread was sweet in comparison to everywhere else.
This. Mainstream food in the US is unbearably sweet and sugary if you come from anywhere else in the world. Drinks are sweet. Chips are sweet. The deep fried onions at Olive Garden are sweet. The gravy for the prime rib is sweet. The goddamn bagels are sweet. They put marshmallows on top of baked sweet potatoes for thanksgiving.
Hmm. Coca-Cola may be a standout here, where sweetness is required for the phosphoric acid balance, because of the tingle that sells their "original" flavor
If you're putting more of one ingredient in, you're either giving a larger product or putting in less of another ingredient. If that other ingredient was more expensive, you have decreased costs.
"Richardson, you effectively raised costs! Here's your bonus. Congratulations!"
The heightened demand for that product may be an incentive, though.
