Zhrnutie<\/div>\n

Kofe\u00edn je prirodzen\u00e1 zlo\u017eka k\u00e1vy.

Tehotn\u00e9 a doj\u010diace \u017eeny by pod\u013ea EFSA mali dodr\u017eiava\u0165 maxim\u00e1lny pr\u00edjem okolo 200 mg denne. Kofe\u00edn sa z tela vylu\u010duje pomaly, a preto ho niektor\u00ed \u013eudia rad\u0161ej obmedzuj\u00fa v popolud\u0148aj\u0161\u00edch a ve\u010dern\u00fdch hodin\u00e1ch.

Kofe\u00edn je jednou z najzn\u00e1mej\u0161\u00edch prirodzene sa vyskytuj\u00facich zlo\u017eiek k\u00e1vy a mnoh\u00ed z n\u00e1s si \u0161\u00e1lku k\u00e1vy sp\u00e1jaj\u00fa so svoj\u00edm ka\u017edodenn\u00fdm rann\u00fdm ritu\u00e1lom. V tomto \u010dl\u00e1nku sa z \u010disto vecn\u00e9ho h\u013eadiska pozrieme na to, \u010do je kofe\u00edn, ako p\u00f4sob\u00ed v tele, ko\u013eko ho obsahuje be\u017en\u00e1 \u0161\u00e1lka a ak\u00e9 mno\u017estvo pova\u017euj\u00fa odborn\u00e9 in\u0161tit\u00facie za bezpe\u010dn\u00e9.<\/p>\n

\u010co je kofe\u00edn a ko\u013eko ho obsahuje k\u00e1va<\/h2>\n

Kofe\u00edn je prirodzenou zlo\u017ekou k\u00e1vov\u00fdch z\u0155n (ako aj \u010daju, kakaa \u010di guarany). Je to jedna z najd\u00f4kladnej\u0161ie presk\u00faman\u00fdch l\u00e1tok v potravin\u00e1ch; v tomto \u010dl\u00e1nku sa zameriavame v\u00fdlu\u010dne na jeho obsah v k\u00e1ve a bezpe\u010dnostn\u00e9 limity pod\u013ea EFSA.<\/p>\n

Kofe\u00edn sa z tela vylu\u010duje postupne. Jeho biologick\u00fd pol\u010das je u priemern\u00e9ho dospel\u00e9ho pribli\u017ene 3 a\u017e 7 hod\u00edn, individu\u00e1lne sa v\u0161ak v\u00fdrazne l\u00ed\u0161i (a po\u010das tehotenstva sa predl\u017euje).

Ko\u013eko kofe\u00ednu obsahuje \u0161\u00e1lka k\u00e1vy<\/h2>\n

Obsah kofe\u00ednu je faktick\u00fd \u00fadaj, ktor\u00fd sa l\u00ed\u0161i v z\u00e1vislosti od druhu k\u00e1vy, odrody, sp\u00f4sobu pra\u017eenia a sp\u00f4sobu pr\u00edpravy. Ide o uvedenie mno\u017estva l\u00e1tky, nie o zdravotn\u00e9 tvrdenie:<\/p>\n

    \n
  • Jedno klasick\u00e9 30 ml espresso (jeden \u201eshot\u201c) obsahuje pribli\u017ene 40 a\u017e 80 mg kofe\u00ednu.<\/li>\n
