Deception is bad, but from a nutritional point of view this really shouldn't be an issue for informed consumers (ie. people who read the ingredient lists) given that "nutrition facts" also exists. 10g of sugar is 10g of sugar, regardless if it came from a strawberry, fruit juices, or HFCS. This is especially true in highly processed foods, where the processing eliminates any advantage that "natural" sugars have.

From a biological pov, that is wrong on so many levels. It is why labels now have Added Sugars listed separately. Sugars as whole fruit aren't unhealthy in moderation, whereas HFCS is one if the unhealthiest added sugars. There is no way to equate them except in pure chemistry with no relation to biology.
No, making the law only protect those who are informed is a poor idea on many fronts.
Firstly, you've incentivized companies to prevent people from becoming informed. You can already see online that lies spread faster because they don't have the inconvenience of needing to be true. You have one truth, and it has to stand up to countless thousands of lies.
Secondly, nobody can be informed about everything. The whole reason we have experts is because they are the ones informed on their subject, and they devote their entire careers to it. You cannot possibly be well-read and up to speed about everything you buy while still being able to function as a human being.
Thirdly, what happens when the deceptive, shitty product completely out-competes the safer one because it's that much cheaper? Hey, guess what? You can't buy the safe or sustainable version of the product anymore because every business that did went out of business. It's no longer in the market.
I want to buy the thing that was the most expensive and exuberant to manufacture for the lowest price. So yeah, when I want jam, I want jam that is the most strawberries. This isn't complicated.
