Obesity and dental caries are increasingly widespread
pathologies. The former is growing so rapidly that the
WHO classified its trend as an “epidemic”. Both are
triggered by a number of well known common etiologic
factors sharing also the high added sugar amount since
childhood. Because of its fermentation and pH lowering,
dietary sugar allows the cariogenic bacteria to damage the
tooth enamel provoking the carious lesions.
WHO guidelines recommend reducing sugar intake to
10% of the total daily energy need, and highlight that
there is evidence which suggests cuttingthis value down to
5% at least. The American guidelines addressing
paediatric age put the limit to 25gr a day with a total ban
on sugar in those aged 2 or less
