High fructose corn syrup uses and possible health effects

What it found

Studies link high fructose intake to obesity and metabolic problems, but those studies used pure fructose at very high doses.

The authors say those results cannot be directly applied to high fructose corn syrup.

What they found

Studies in people and animals

Obesity and metabolic syndrome

Reports suggest a direct link between high fructose intake and problems like obesity and metabolic syndrome.

Other findings

Where it is used

High fructose corn syrup is added to bakery products, dairy items, breakfast cereals and drinks because of its physical and functional qualities.

Pure fructose versus syrup

Earlier studies tested pure fructose at very high concentrations to measure metabolic upsets. The authors say those findings cannot be directly applied to high fructose corn syrup.

What the authors conclude

  • They note that studies showing harm from fructose used pure fructose at very high concentrations rather than high fructose corn syrup.
  • They argue that the negative findings from those studies cannot be directly applied to high fructose corn syrup.

How it was done

High fructose corn syrup is widely used in foods and drinks as a sugar substitute. Reports linking high fructose intake to weight gain and metabolic problems have drawn attention to it.

The authors looked at the benefits and possible downsides of using high fructose corn syrup in the food industry. They examined how earlier studies measured metabolic problems using pure fructose at very high concentrations.

What it can’t tell you

  • We summarised it from the abstract only.
  • Studies testing pure fructose at very high doses may not reflect what happens when people eat high fructose corn syrup in normal amounts.
  • A review summarising other work cannot by itself prove cause and effect.
