Vulnerability to Fructose Varies, Health Study Finds

[Nelson Vergel]

Fructose, a sugar widely consumed in the form of high-fructose corn syrup, may promote obesity and diabetes by overstimulating a hormone that helps to regulate fat accumulation, researchers reported on Monday.

The study, carried out at Harvard Medical School, marks the first time that scientists have identified a hormone that rises sharply and consistently in response to eating fructose. The finding suggests that people may vary in their sensitivity to the sugar, and that eventually it may be possible to test an individual for susceptibility to illnesses linked to weight gain.

Fructose stimulated the sharpest rise in the hormone in people who were obese, an increase that the researchers believe may trigger resistance to its effects, according to the study, which was published in the journal Molecular Metabolism. But even among lean people, there was wide variation in this response.

Fructose vs Glucose vs. HFCS: Fight!

Animal studies have suggested that fructose may be uniquely harmful, among the different types of sugars. We analyzed a recent study that actually compared fructose against glucose (and against high-fructose corn syrup) in humans, to see if they have different impacts on inflammation and gut...

Here are some of the main foods and beverages that are high in fructose:

## Fruits High in Fructose
- Mangoes, figs, grapes, pears, apples, watermelon, pomegranates, persimmons, cherries, blackberries, blueberries [1,3,4]
- Dried fruits like raisins, dates, prunes [3,4]

## Sweeteners High in Fructose
- Honey (up to 40.9% fructose) [1]
- Agave nectar/syrup [2,6]
- High fructose corn syrup (42-55% fructose) [7]

## Beverages High in Fructose
- Fruit juices and juice drinks [2,4,7]
- Regular sodas/soft drinks [4,7,8]
- Sweet teas, horchata [1,4]
- Dessert wines [1]

## Other Foods High in Fructose
- Sweetened yogurts [1]
- Baked goods like pies, pastries, cookies [1,8]
- Condiments like ketchup, barbecue sauce [1,8]
- Fast foods with added fructose syrups/sweeteners [1,7,8]
- Processed snacks and candies [8]

While whole fruits contain natural fructose along with fiber and nutrients, foods with added fructose sweeteners like high fructose corn syrup are major sources of excess fructose in the modern diet. Limiting these processed foods high in added fructose is recommended for better health. [1,2,3,7]
