Controversial review backs restricting sugar

Accumulating epidemio­logical data linked excess fructose with risk factors for CV disease and limiting consumption may lead to substantial health benefits, the authors said, adding there was a paucity of evidence on statistical associations between excess fat/salt intake and CV disease.

“We speculate from the evidence… that dyslipidaemia, hyperuricaemia, a diagnosis of type 2 diabetes, hypertension and obesity – all of which are themselves associated with incident cardiovascular disease – all have evidence of a statistical association with excess intake of fructose,” they wrote.
