If fructose is much more toxic than glucose then NO, they are NOT identical since it would depend on the ratio between fructose to glucose.

It would dependt on the concentration of fructose vs glucose in HFCS, so in theory HFCS might be diffren.

>> The 2 most important HFCS products of commerce contain 42% fructose (HFCS-42) and 55% fructose (HFCS-55). The remaining carbohydrates in HFCS are free glucose and minor amounts of bound glucose, predominantly maltose (di-glucose) and maltotriose (tri-glucose). Mention of HFCS with higher fructose content (ie, HFCS-80 or HFCS-90) is occasionally seen in the literature, but these products are highly specialized and are manufactured infrequently and in insignificant amounts.

Eg a potato and an apple might have the same amount of carbs, but since an apple has more fructose it's more toxic (assuming we only measure toxicty based on the glucose:fructose ratio).

It matters how quickly it is absorbed and the actual -amount- as usual. Apple has far less "energy" per volume than a potato. You can't just look at ratios obviously. all that glucose gets broken down into sucrose and fructose and that's the point. Being toxic is a function of both "chemical" and amount. a potato will have a much higher amount of fructose per unit that an apple after it all gets broken down, an apple also has fiber that will slow down the absorption of the glucose/fructose.The ratio of fructose/sucrose in standard issue is such that it should be slightly worse than cane sugar, but not that much worse.

What are you even talking about?

You mixed many words + potato has practicaly 0 fructose compared to an apple.

When a potato is eaten, the amylase in the saliva mixes with the potato starch and starts breaking it down into sugars, some wil be glucose acording to [1].

You can test this yourself by eating a plain cracker. A plain cracker doesn't contain any sugar, but if you keep chewing it you will notice a sweet taste in the mouth. This is from the sugars released by amylase.

There is no mention of fructose on the amylase wikipedia page. So maybe you are right.
