'Healthy' sweetener linked to high blood pressure

An ingredient in processed foods and soft drinks could be a recipe for high blood pressure, research suggests.


High fructose corn syrup (HFCS) is abundant in many types of foods and beverages and was originally viewed as a "healthy" method of sweetening.

Its introduction 20 years ago has caused consumption of the fruit sugar fructose to rise sharply, alongside increasing levels of obesity.

Although healthy amounts of fructose exist naturally in fruit, excessive amounts of the sugar may be harmful. Large quantities of fructose cause the liver to pump fats into the bloodstream that may damage arteries.

Researchers who carried out the new study in the US looked at more than 4,500 adults with no prior history of high blood pressure, also known as hypertension.

Fructose intake was calculated using a dietary questionnaire which asked participants to rate their consumption of foods such as fruit juices, soft drinks, bakery products and confectionery.

The study found that people who ate or drank more than 74 grams of fructose per day - equivalent to 2.5 sugary soft drinks - increased their risk of developing high blood pressure.

Blood pressure readings consist of two figures. The first "systolic" reading relates to when the heart is actively pumping. The second "diastolic" reading shows the blood pressure between beats.

"Normal" blood pressure is said to be a reading of around 120/80 millimetres of mercury (mmHg) depending on age.

Consuming more than 74 grams of fructose a day increased the chances of a reading of 135/85mmHg by 28 per cent, the study found. It also raised the risk of higher readings of 140/90mmHg and 160/100mmHg by 36 per cent and 87 per cent respectively.

The findings were presented today at the annual meeting of the American Society of Nephrology in San Diego, California.

Dr Diana Jalal, from the University of Colorado, and colleagues wrote in their paper: "These results indicate that high fructose intake in the form of added sugars is significantly and independently associated with higher blood pressure levels in the US adult population with no previous history of hypertension."

Further work was needed to see if lowering fructose consumption could normalise blood pressure, they said.

Americans today consumed 30 per cent more fructose than they did 20 years ago and up to four times more than they did 100 years ago, said the researchers.

I noticed they used the word "associated" with high blood pressure instead of the usual "linked" which essentially means unproven.

I think the idea was that fructose itself (not necessarily HFCS) is "healthy" for diabetics because it doesn't cause a glycemic response. They're still trying to spin agave syrup that way.

I saw Dr Oz pushing agave syrup at some poor woman a few weeks ago.

Yes, I know diabetics, one on dialysis who swear by agave syrup as a sweetener saying "it doesn't raise blood sugar."

It doesn't surprise me that Dr. Oz pushes it too.

Here's another article on the subject: A Recipe For Hypertension: High Fructose Corn Syrup]

Of course, hypertension is just one of the symptoms of insulin resistance:

Hypertension, fatty liver, obesity, high uric acid, gout, blood sugar disorders, etc.

Oh yes, NephroPal has an article too:http://nephropal.blogspot.com/2009/...standpoint.html

this is worth reading if you can get the full text

The only problem with just talking about HFCS is that it doesn't address the issues with sugar (sucrose), which is nearly as bad.

By whom?? Coca-cola?

Speaking of Coca-cola, several large billboards have recently appeared in our town advertising two-pack liter bottles of Coke. "Enough for your meal!" it says. I guess for plenty of American families, a meal isn't a meal without a humongous slug of HFCS.
