Fructose Linked to High Blood Pressure
A study published recently in the July 2010 issue of the Journal of the American Society of Nephrology found that diets high in fructose may significantly increase the risk of developing high blood pressure.
Researchers from the University of Colorado, Anschutz Medical Campus analyzed the diets of over 4,500 adults for the study.
The researchers looked at the participant’s consumption of any foods with added fructose including high fructose corn syrup, sucrose and table sugar.
They found that participants who consumed more than an average of 74 grams/ day (equivalent to 2.5 20 oz bottles of soda) were 87% more likely to have high blood pressure.
They also found that the increase in blood pressure was by no means minimal, with many of the participants with high fructose consumption recording blood pressures around 160/100. Normal blood pressure is 120/80.
It was noted that these findings do not show cause and effect, rather they just highlight an association. However, previous animal studies have shown that high intakes of fructose may cause high blood pressure by increasing salt absorption through the gut.
Studies have also shown that this simple sugar may increase the risk of obesity and heart disease. Since fructose is most commonly found in packaged foods, junk food, fast food and soft drinks, minimizing consumption of these foods is a good way to reduce the amount of fructose in your diet.
