To assess the contribution of ultra-processed foods to the intake of added sugars in the US diet, the researchers drew on
dietary data involving more than 9000 people from the 2009 - 10 National Health and Nutrition Examination Survey (NHANES), an ongoing nationally representative cross sectional survey of US civilians.
«These
data are fully in accord with recent work on the actions of reactive oxygen species in cells, although clearly at odds with the popular concept that
dietary antioxidants are inevitably beneficial,» says Malcolm Jackson at the University of Liverpool, UK, who was not
involved in the research.
