Kohv on vastuoluline teema, kuid viimasel ajal avaldatud laiapõhjalised uuringud viitavad üheselt, et paljud kohvi joomisega seotud hirmud võib rühmitada folkloori hulka.
Uuringud näitavad, et kohvi joomine:
- vähendab eesnäärme-, rinna-, kolorektaal-, endomeetriumi- ja maksavähi riski
- parandab insuliinitundlikkust ja vähendab diabeedi riski
- kaitseb rakukahjustuste eest
- kaitseb maksa
- vähendab sapikivide tekkeriski
- suurendab soolefloora variatiivsust
- kiirendab ainevahetust
- kaitseb südant
- vähendab insuldi riski
- parandab kognitiivset funktsiooni i.e. mälu ja otsustusvõimekust
- on neuroprotektiivse toimega i.e. vähendab Parkinsoni tõve riski
NB! Kohv EI mõjuta halvasti suuõõne bakteriaalset kooslust! Otse vastupidi, on uuringuid, mis viitavad tõenäosusele, et kohvil võivad olla ka teatud positiivsed, kaariesevastased mõjud.
Oluline on teadvustada, et kohv ei sisalda ainult kofeiini, vaid seal on sadu erinevad polüfenoolseid ühendeid, kiudaineid ja antioksüdante, mis sünergilises koosmõjus toimetavad, meie soolestiku mikrofloorale ja seeläbi ka immuunregulatsioonile mõju avaldavad.
Niisiis on ka kofeiinivaba kohv hea valik, sest kuigi seal on vähem kofeiini, jäävad teised boonused jooki ikka alles.
Üks uskumatult olulisi teadmisi on seejuures, et kohv on rafinaatidest läbi imbunud läänelikus menüüs oluline kiudaine allikas! Tass kohvi sisaldab ca 1,5g kiudaineid s.t. oluliselt rohkem kui nt klaas apelsinimahla(!), mis tähendab, et 2 tassi kohvi sisaldab rohkem kiudaineid, kui nt banaan, ning 3 tassi joomisega päevas võib kokku saada juba uskumatud 4,5-5 g kiudaineid, mis on ca 1/4 tänapäeva keskmise inimese menüü kiudianete sisaldusest.
NB! Kofeiinitaluvus on väga isiklik ja on tegureid, mis seda tugevalt mõjutavad, nt. geenid ja võimekus kofeiini metaboliseerida (ainevahetada). Niisiis saavad mõned endale rohkem kohvi lubada, teised aga vähem.
P.S. Kofeiini ainevahetust kiirendab tugevalt suitsetamine ja aeglustab antibeebipillide tarbimine. Kohviga peaksid ettevaatlikumad olema ka lapseootel naised.
Liialdamine ei tule kasuks ühegi asja puhul, kuid need, kes kohvi armastavad ja hästi taluvad, võivad omale teadmiseks võtta, et 1-3 tassi kvaliteetset kohvi päevas on suurepärane valik!
