Researchers from the University of Colorado Denver and Mateo Orfila Hospital in Minorca studied 75 men who each consumed 200g of fructose daily in addition to their normal diet. Average daily intake of fructose is estimated to be 50-75g.
After two weeks the men's systolic BP increased by 6mmHg and their diastolic BP rose by 3mmHg.
'These results suggest that fructose may be a cause of metabolic syndrome,' the researchers said. 'They also suggest that excessive fructose intake may have a role in the worldwide epidemic of obesity and diabetes.'
The findings were presented at the American Heart Association's high BP research conference this week.
