This is potentially surprising given that fructose (used in HFCS) has a lower glycemic index than sucrose (used in table sugar).

Taubes explains this (sort of) by explaining that fructose goes straight to the liver, thus not contributing to glycemic index, but doing something to the liver related to insulin to make fat cells more likely to uptake the glucose in the blood. The science isn't fully understood, but it is definitely testable.

From my possibly simplistic understanding:

Insulin resistance is a factor in Type 2 diabetes, which wrecks the body's ability to handle glucose.

Once you get to this point, damage to body systems starts to snowball, obesity, kidney failure etc.

Sugar prices are supported by tariff in the US, and corn prices are subsidized. This abomination is wrecking the health of the population.

It was striking on a recent visit to Canada, that nothing in the shops, even cereal appeared to include HFCS as an ingredient.

But still, Canada also faces an obesity epidemic.

Fructose is sweeter. It actually seems the taste of sweet alone triggers an insulin response that causes fat storage. Zero calorie sweeteners have been shown to cause fat gain.
