Avoid fructose - don't eat fruit - to avoid diabetes

There are many good reasons to avoid the fruit sugar, fructose, but all you need is one: type 2 diabetes. And even worse than fruit itself that ubiquitous additive to so many processed foods and drinks — high fructose corn syrup.

A recent study highlighted diabetes and all the other key reasons why it's a healthy idea to avoid this truly awful component of processed foods and soft drinks.

US researchers at the University of California, Davis (UCD), presented a new fructose study at the American Diabetes Association 67th Annual Scientific Sessions in Chicago. It was a follow up to a similar study published 5 years earlier

The 2002 UCD study reported on animal testing that showed how fructose consumption contributed to insulin resistance, high blood pressure, and elevated triglyceride levels - three of the core symptoms of metabolic syndrome. Other metabolic syndrome symptoms include excessive abdominal fat, high C-reactive protein level, and low HDL cholesterol. Three or more of these symptoms put a patient at high risk of developing type 2 diabetes and heart disease.

In the conclusions to their 2002 study, the UCD team noted that a high intake of fructose might increase body weight and encourage insulin resistance. Five years later, a study of human subjects confirms those conclusions.


The UCD researchers began by giving a series of tests to assess heart disease risk in 23 overweight adults, aged 43 to 70.

  • For two weeks, each subject ate a strict diet that consisted of 30% fat, and% complex carbohydrates
  • After the first phase was complete, subjects were allowed to eat whatever they liked for eight weeks, along with three sweetened beverages each day that supplied a quarter of their energy intake - about half the group drank a glucose beverage while the other half drank a fructose beverage
  • After the second phase was complete, subjects returned to the 30/55 diet while continuing with their daily drinks
  • Throughout the study, further checks of heart disease indicators occurred at two, eight, and 10 weeks

Results showed that just two weeks after subjects began drinking sweetened drinks, triglyceride levels were up in the fructose group, but had actually dropped in the glucose group. Over the entire range of the study, LDL cholesterol increased and insulin sensitivity decreased in the fructose group but didn't change in the glucose group. In addition, fructose subjects gained about three pounds overall, but no weight gain was reported in the glucose group.

A fructose by any other name...

UCD researcher, Dr Peter J. Havel (who participated in both the 2002 and 2007 studies),said that most people get added sugars in their diet from daily beverages. As this is a lifelong habit, it far exceeds the two weeks in which fructose proved to be so harmful in the trial.

So what exactly do soft drinks contain?

Checking the ingredients of your soft drink, sports tea, vitamin water, power drink, etc., you might wonder what the difference is between fructose, high fructose corn syrup, and crystalline fructose. Is one better than the other? Well...put it this way: If only part of your house is on fire, your house is still on fire.

The average high fructose corn syrup is made up of about 50 percent fructose. But according to the Sugar Association (, increased fructose content of HFCS is becoming more common. Some of these syrups contain more than 90 percent fructose.

And then there's crystalline fructose that's present in many "health" drinks and vitamin-enhanced beverages. But does the process of crystallizing magically transform fructose into something healthy? No. According to the Fructose Information Center (, crystalline fructose is nearly 100% fructose. And just to make it even less appealing, it contains traces of lead, chloride, and arsenic. Yum! And keep in mind this information comes from an association that ADVOCATES fructose use and consumption.

All of this is very bad news for those who are fructose intolerant and don't even know it. They may suffer from chronic problems such as irritable bowel syndrome without making the connection between their condition and their fructose intake.
