Eating a diet high in added sugar may increase the risk of developing hypertension, according to researchers at the University of Colorado Denver Health Sciences Center.

Scientists analyzed data from the National Health and Nutrition Examination, which involved more than 4,500 American adults over the age of 18 with no prior history of high blood pressure. Study participants answered questions related to their consumption of foods and beverages such as fruit juices, soft drinks, bakery products and candy.

The study found that those who consumed the largest amounts of sugar (more than 74 grams per day) in their diets had an increased risk for hypertension.

"Our study identifies a potentially modifiable risk factor for high blood pressure," said the study’s lead author, Diana Jalal, M.D. "However, well-planned prospective randomized clinical studies need to be completed to see if low fructose diets will prevent the development of hypertension and its complications."

Hypertension is the most common chronic condition in developed countries and a major risk factor for heart and kidney diseases.

Experts say it can be prevented with lifestyle changes like weight loss and exercise, as well as nutritional supplements containing potassium, calcium, fish oil, magnesium and garlic.
