We already know a bit about fructose and how it compares to other sugars. I would avoid assuming that this was some intentional 4D science chess maneuver, though. The only real reason high fructose corn syrup is used is because it is cheap. The money they earn from fructose getting people to buy more food pales in comparison to the amount of money they saved using corn syrup instead of sugar.

And fat and dietary cholesterol in general.

I’ve eaten about a dozen eggs a week for 50ish years, and my heart health is fine. Just stick to whole foods, move a lot, and don’t eat trash.

Highly processed foods are the real enemy, but that’s where most of the money is. Food corporations will almost literally crap on a plate and serve it up as a sundae.

It’s always confused me the way sugar was treated as a staple for so long.

In descriptions of daily life in the 19th century, you’ll see a provisions list like “flour, canned beans, dried meat, tallow, loaf of sugar…”

When the going was rough, why was it so important for people to have such a useless delicacy as sugar? Even the Donner Party prioritized it if my reading recollection is right.

It's worth saying that this is true of almost all food. There are tons of essential nutrients that you basically can't absorb or use without gut bacteria, which is why microbiomes are so important for digestive health.

The fact that fructose has to be broken down first (in the liver) is essentially trivia (and information about what you can eat after antibiotics/surgery) rather than some deep statement about what is "natural" for humans to consume (which I think is what the comment you responded to was implying).

Edit: I think fructose is actually broken down in the liver, not the digestive tract. The point still stands though: the digestive system is complex, and the chain being more than one step long is normal.
