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...

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.

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.

Eating normal amounts of table sugar or corn syrup in your food and drinks doesn’t make you more likely to get overweight, diabetes, or heart disease than eating the same number of calories from other carbs like bread or pasta.

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

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.
