Ve velk\u00fdch supermarketech nakoupil 18 zava\u0159enin, u nich\u017e zkoumal obsah ovoce, cukru a chu\u0165. \u201eDo testu jsme vybrali na prvn\u00ed pohled t\u00e9m\u011b\u0159 toto\u017en\u00e9 v\u00fdrobky, ov\u0161em podle deklarac\u00ed na obalu \u0161lo o produkty \u010dty\u0159 r\u016fzn\u00fdch kategori\u00ed.
