Quand on parle d\u2019immunit\u00e9, on pense souvent aux vitamines, au sommeil ou au stress. Pourtant, l\u2019intestin joue un r\u00f4le central dans la r\u00e9ponse immunitaire \u2014 et c\u2019est l\u00e0 que les probiotiques entrent en jeu.<\/p>\n
Mais les probiotiques renforcent-ils r\u00e9ellement l\u2019immunit\u00e9?<\/p>\n
La r\u00e9ponse est plus nuanc\u00e9e qu\u2019un simple oui ou non.<\/p>\n

Les probiotiques sont des bact\u00e9ries vivantes qui, lorsqu\u2019elles sont consomm\u00e9es en quantit\u00e9 ad\u00e9quate, peuvent avoir des effets b\u00e9n\u00e9fiques sur la sant\u00e9 digestive.<\/p>\n

\u2022 Dans certains aliments ferment\u00e9s, comme le yogourt ou le k\u00e9fir<\/p>\n
Chaque souche a des fonctions sp\u00e9cifiques.
