Some sweetened drinks and fruit juices have more unbound fructose sugar than table sugar, which is made of fructose and glucose molecules stuck together.

How it works

In drinks with high-fructose corn syrup or some fruit juices, the fructose is already floating around freely, not stuck to glucose. In regular sugar, fructose and glucose are glued together and don’t separate until your body digests them. That’s why those drinks give you more free fructose right...

Most probable mechanism

In Simple Terms

In drinks like high-fructose corn syrup sweetened beverages and some fruit juices, fructose is already separated from glucose and floats freely in the liquid, unlike in table sugar where fructose and glucose are stuck together. This means when you drink these beverages, your body gets a lot of free fructose right away without needing to break anything apart.

Causal chain
1

Fructose is present as a free monosaccharide in high-fructose corn syrup due to its industrial production process that separates fructose from glucose before blending.

2

In some 100% fruit juices, cellular disruption during juicing releases fructose from its original bound state within plant cells, resulting in unbound fructose molecules in the liquid.

3

In sucrose, fructose and glucose are chemically bonded as a disaccharide, requiring enzymatic cleavage before absorption, so no free fructose is present until digestion begins.

Similar Assertions

Beverages sweetened with high-fructose corn syrup have about 60.6% fructose and 40.4% glucose by weight, making fructose 50% more abundant than glucose. This differs from table sugar, which contains equal amounts of fructose and glucose.

Beverages sweetened with high-fructose corn syrup contain more fructose relative to glucose than table sugar does, and because dietary surveys treat all added sugars as if they were table sugar, they may not accurately capture how much fructose people are consuming.

Fruit juices made purely from fruit can have up to 67% of their sugar as fructose, which is about twice as much as glucose, making their sugar profile similar to that of sodas sweetened with high-fructose corn syrup.

When scientists measure the sugar in drinks sweetened with high-fructose corn syrup using three different lab methods, they get the same results for the ratio of fructose to glucose, showing the measurements are consistent.

Lab studies that give people pure fructose or pure glucose don’t reflect what people actually eat — we usually consume sugar as table sugar or corn syrup, which are mixtures, so those lab results don’t apply to real life.
