\"Cafeaua<\/a>Mai mult de 4 cafele, adic\u0103 aprox. 400 miligrame de cafein\u0103 pe zi, sunt nocive pentru s\u0103n\u0103tate – dac\u0103 nu punem la socoteala \u0219i alte surse de cafein\u0103. Pentru cine nu bea cafea, atentie la cafeina continut\u0103 \u00een bauturi racoritoare (tip cola), b\u0103uturi energizante, ciocolat\u0103, ceai negru, ceai verde!<\/p>\n

Este pentru prima data cand Autoritatea europeana pentru siguranta alimentelor (EFSA) face o evaluare \u0219i emite o recomandare, la nivelul Uniunii europene, asupra riscului prezentat de cresterea consumului de cafeina, incluz\u00e2nd toate sursele alimentare: boli cardiovasculare, probleme legate de sistemul nervos central (somn intrerupt, anxietate), posibile riscuri pentru f\u0103t la femeile insarcinate.<\/p>\n

In 7 dintre cele 13 \u021b\u0103ri studiate de EFSA, o parte a popula\u021biei adulte consuma mai mult dec\u00e2t recomandarea de 400 mg. Danemarca e \u00een frunte, 33 % dintre adul\u021bi abuzeaz\u0103 de cafeina, urmat\u0103 de Olanda (17,6 %), Germania, (14,6 %), Finlanda (13,4 %), Belgia (10,4 %), Suedia (9 %), Fran\u021ba (5,8 %).<\/p>\n

Un studiu realizat cu ceva vreme \u00een urm\u0103, arat\u0103 c\u0103 \u00een topul b\u0103uturilor nealcoolice consumate de rom\u00e2ni se afl\u0103 apa \u00eembuteliat\u0103, cu 66,2%, urmat\u0103 de cafea – 64%, lapte – 53,4%, ceai – 44,5%,<\/p>\n

\"Mousse<\/a>Doza individual\u0103 de cafein\u0103 considerat\u0103 f\u0103r\u0103 risc pentru adul\u021bi este de 3 mg\/kg corp pe zi. Aceeasi doz\u0103 este recomandat\u0103 \u0219i copiilor, pentru c\u0103 viteza de eliminare a cafeinei la copii si adolescen\u0219i este cel pu\u021bin egal\u0103 cu cea a adul\u021bilor.<\/strong><\/span><\/p>\n

Concret, in cazul unei persoane care c\u00e2nt\u0103re\u0219te 70 de kg, cantitatea de cafein\u0103 recomandat\u0103 zilnic este de 210 miligrame. Ca s\u0103 ave\u021bi un etalon, mai jos c\u00e2teva valori.<\/p>\n

Tot EFSA spune c\u0103 un consum de p\u00e2n\u0103 la 400 mg pe zi (\u00een jur de 5,7 mg\/kg corp), distribuit pe \u00eentreaga zi, nu ridic\u0103 probleme la adul\u021bii s\u0103n\u0103to\u0219i, cu excep\u021bia femeilor \u00eens\u0103rcinate.<\/p>\n

Studiul acesta nu o spune, dar completez eu din alt\u0103 surs\u0103: cafeaua contine mai mul\u021bi compu\u0219i antioxidan\u021bi.<\/p>\n

\u00cen acest sens, un studiu norvegian arat\u0103 c\u0103, dintre toate sursele de hran\u0103 zilnic\u0103, cea care contribuie cel mai mult la aportul total de antioxidan\u021bi, la aceast\u0103 popula\u021bie, este cafeaua.<\/span><\/span><\/p>\n

Printre compu\u0219ii antioxidan\u021bi ai cafelei se num\u0103r\u0103 compu\u0219ii fenolici, unele substante volatile produse \u00een timpul pr\u0103jirii, <\/span>acidul cafeic \u0219i clorogenic. <\/span>O cea\u0219c\u0103 de 200 ml de cafea furnizeaz\u0103 \u00eentre 70 \u0219i 350 mg de acid fenolic.

\n<\/span><\/p>\n

Totu\u0219i, cele mai multe dintre datele asupra leg\u0103turii dintre consumul de cafea \u0219i reducerea maladiilor cronice au fost ob\u021binute plec\u00e2nd de la studii epidemiologice (studiul raportului dintre boal\u0103 sau orice alt fenomen biologic \u0219i diver\u0219i factori susceptibili s\u0103 exercite o influen\u021b\u0103 prin frecven\u021ba lor, distribu\u021bie, evolu\u021bie). Conform anumitor cercet\u0103tori, datele acestea trebuie interpretate mai degrab\u0103 cu pruden\u021b\u0103 c\u0103ci pot interfera cu normele metodologice. De exemplu, modalitatea de a calcula cantitatea de cafea si cafeina consumate zilnic, pot varia foarte mult de la studiu la studiu (varia\u021bie dat\u0103 de m\u0103rimea c\u0103nii de cafea, durata de infuzare, tipul de boabe utilizate <\/span>etc.). <\/span>\u00cen plus, anumi\u021bi factori care se “confund\u0103” cu cafeaua, precum alcoolul, \u021big\u0103rile, de multe ori asociate cu consum ridicat de cafea, nu sunt \u00eentotdeauna bine evaluate .<\/span><\/span><\/p>\n

Concluzie: cel mai sigur pentru s\u0103n\u0103tate este un consum moderat de cafea:\u00a0 2-3 ce\u0219ti pe zi, de preferat la filtru (spre deosebire de cafeaua preparat\u0103 la ibric, utilizarea h\u00e2rtiei de filtru \u00een timpul prepar\u0103rii cafelei permite reducerea semnificativ\u0103 a concentra\u021biei de <\/b>cafestol<\/strong> \u0219i\u00a0kahweol, compu\u0219i responsabili de cre\u0219terea colesterolului \u00een s\u00e2nge<\/b>) \u0219i\/ sau 2-3 tablete ciocolat\u0103 neagr\u0103.
