So the problem with hfcs is that it's everywhere. And not just like juice, I'm talking like canned goods, deli meat, peanut butter, crackers, bread. So it's really hard to avoid unless you just make everything from scratch. And not I'm advocating for a total abolishment but it's easy to go over your daily sugar with it being in everything. I would try to limit it or maybe have a warning on packages.
For the other person that linked a study, I looked into one of the guys that did it, and he does just like a lot of hfcs studies, like a weirdly amount and I found that kinda sus lol
This site lists papers for and against the safety
It's not as bad as all that, I've cut it out of my diet for about fifteen years. It involves A LOT of reading ingredient labels but for just about everything it's in, there is an alternative without. Sometimes it does come at a premium, though. In the past ten years or so a lot of food manufacturers realized there was a market for foods without it and often advertise it on the label (breads especially). With some things like soda, you can get real sugar, glass bottled sodas which are expensive, but another alternative is drinking water which you should be doing anyway.
I agree that you can avoid hitting the daily sugar thing (and avoid hfcs) by reading ingredients but I don't think many consumers do that. I certainly did not expect it find it in canned tomatoes and I use that in a lot of the recipes I found online. It makes sense why it's in there though if it's acting as a preservative. In fact, I'm going agree with a lot of folks here and just would like to send an end to corn subsidies.
