Spain's popular cafe bombón spikes blood sugar — nutritionists warn against copying it

Cafe bombón — espresso poured over sweetened condensed milk — is one of Spain's most popular coffee drinks. Despite its small size, it contains more calories than an unprocessed breakfast and causes a sharp spike in blood glucose followed by a rapid crash. Nutritionists advise treating the Catalan speciality as an occasional afternoon dessert rather than a daily drink.
