Dacă ai fost vreodată îngrijorat sau chiar curios de cantitatea de cafeină pe care o consumi în mod obișnuit, cu siguranță ai căutat de multe ori informații despre câtă cofeină este în de fapt în cafea. Se pare că nu există un răspuns simplu. Tipul de boabe, metoda de preparare și nivelul de prăjire au toate un rol în conținutul de cofeină din cafeaua de dimineață.

Mai jos vei regăsi informații despre câtă cofeină este în băutura ta de cafea preferată – fie că este la filtru, espresso, cold brew sau instant – și cum se compară cu recomandările medicale pentru consumul de cofeină.

Cofeina este cea mai populară substanță psihostimulantă din lume, utilizată în întreaga lume pentru a începe dimineți lente sau pentru a ne ridica moralul în după-amiezi plictisitoare. Molecula de cofeină se leagă de receptorii de adenosină din creier, prevenind senzația de somnolență.

Acum vom analiza cateva tipuri de cafea populare și nivelul lor de cafeină.

Tip de cafeaCantitate(porție)Conținut de cafeină
Cafea instant240 ml30 – 90 mg
Cafea decafeinizată240 ml3 – 4 mg
Cafea neagră240 ml70 – 140 mg
Cold brew480 ml200 mg
Espresso scurt30 ml(un shot)60 – 80 mg

Cafea neagră

Deci, câtă cafeină conține cafeaua neagră? De obicei între 70-140 mg de cafeină per ceașcă de 240 ml. Cantitatea de cafeină dintr-o ceașcă de cafea poate varia în funcție de metoda de preparare și tipul de boabe. Boabele Robusta conțin aproape de două ori mai multă cafeină decât cele Arabica, în timp ce cafelele Liberica și Excelsa sunt natural scăzute în cafeină.

Espresso

O singură doză de espresso conține de obicei între 30 și 65 mg de cofeină, în funcție de tipul de espresso și de cantitatea de cafea utilizată. O singură doză de espresso conține în mod obișnuit aproximativ 63 mg de cofeină, în timp ce o doză dublă de espresso conține, în mod obișnuit, aproximativ 125 mg de cofeină.

Dacă obișnuiți să beți espresso, puteți măsura mai bine consumul de cofeină! Concentrația de cofeină a espresso-ului este în general mai controlată, deoarece dimensiunea porției este standardizată la 30 sau 60 de ml. Acest lucru asigură o cantitate precisă de consum de cofeină.

Cafeaua decafeinizată

Deși percepția populară este că cafeaua decafeinizată nu conține deloc cafeină, acest lucru nu este complet adevărat. Cafeaua decafeinizată conține încă mici urme de cofeină. Cel mai popular proces de decofeinizare, metoda Swiss Water, poate elimina până la 99% din cofeină.

O ceașcă de 240 ml de cafea decafeinizată preparată prin fierbere conține aproximativ 3-4 mg de cofeină.

Cafea instant

Cafeaua instant este obținută prin atomizarea boabelor, ceea ce îi oferă o durată de viață mult mai scurtă. Datorită preparării instantanee, cafeaua instant conține în mod obișnuit mai puțină cofeină decât cafeaua proaspăt preparată, o ceașcă de 240 ml conținând aproximativ 62 mg de cofeină. O ceașcă de cafea instant conține de obicei între 30 și 90 mg de cofeină, fiind deci o băutură mai puțin puternică decât cafeaua obișnuită.

Cold brew

În final, clasicul cold brew! Acest tip de băutură conține niveluri mai ridicate de cofeină decât cafeaua obișnuită, între 182 și 280 de miligrame per porție.

Trebuie să îmi fac griji despre câtă cofeină consum?

Nivelul de cofeină consumat este ceva ce anumite persoane ar trebui să monitorizeze, în funcție de starea lor generală de sănătate. Dacă te consideri o persoană sănătoasă, poți consuma în siguranță până la 400 sau 600 mg în fiecare zi. Totuși, unele cercetări au legat consumul de cofeină de peste 600 mg pe zi de efecte neplăcute precum anxietate, tulburări de somn, palpitații, dureri de cap, oboseală și neliniște.

În concluzie

Concluzia este că este dificil să ajungi la o “supradoză“ de cofeină indiferent de felul în care prepari cafeaua. Chiar dacă îți place o cafea la filtru dimineața, un latte după-amiaza sau o cafea rece în timpul verii, nu există niciun motiv să reduci cantitatea, cu excepția cazului în care întâmpini efecte adverse. Respectă doza zilnică recomandată și bucură-te de efectele energizante ale celui mai popular “drog“ din lume.
