Gut Brain Evidence

Slabi

Utječu li probiotici na raspoloženje?

Meta-analize su blago pozitivne. Ispitivanja na kojima se temelje dovoljno su mala, kratka i heterogena da bi blaga pozitivnost bila ono što biste očekivali i kad ništa ne bi djelovalo.

Što pokazuju meta-analize

Skupne analize probiotika, prebiotika i sinbiotika za simptome depresije i anksioznosti pokazuju male pozitivne učinke [1][2][4], a sustavni pregled dolazi do sukladnih zaključaka [3]. Uzeto zdravo za gotovo, to je pozitivan nalaz.

Uzeto zajedno s obilježjima studija, nalaz je mnogo slabiji. Ispitivanja su mala, kratka, koriste različite sojeve u različitim dozama i mjere ljestvice simptoma u nekliničkim populacijama gdje je regresija prema srednjoj vrijednosti znatna. Male pozitivne skupne učinke iz literature s takvim obilježjima upravo proizvodi pristranost objavljivanja.

Probiotici za raspoloženje

Problem soja

To je problem koji većina potrošačkih izvještaja propušta. Lactobacillus rhamnosus GG i Bifidobacterium longum 1714 različiti su organizmi s različitim metaboličkim produktima. Dokazi za jedan ne govore ništa o drugom, isto kao što se dokazi za jedan antibiotik ne prenose na drugi.

Većina proizvoda u prodaji na deklaraciji navodi rod i vrstu bez oznake soja, što znači da ih ne možete povezati s bilo kojim ispitivanjem, čak i ako relevantno ispitivanje postoji. Proizvod koji ne navodi soj u praksi nema nikakve dokaze.

Gdje probiotici imaju bolje dokaze

Literatura o raspoloženju najslabija je karika. Postoje snažnije primjene i vrijedi biti jasan oko te razlike:

  • Dijareja povezana s antibioticima. Razumni dokazi, specifični sojevi.
  • Prevencija dijareje putnika. Meta-analizirano s umjerenim učinkom — pogledajte našu stranicu o zdravlju putnika.
  • Kolike u dojenčadi, za određene sojeve.
  • Pouchitis nakon kolektomije, gdje su dokazi relativno snažni.

Što je zajedničko ovima: specifično stanje, specifičan soj i uvjerljiv kratak kauzalni lanac. Raspoloženje nema ništa od toga.

Što učiniti umjesto toga

Hranite bakterije koje već imate. Vlakna i fermentirana hrana pouzdanije mijenjaju mikrobiom nego gutanje kapsule organizama koji se uglavnom ne koloniziraju — pogledajte vlakna. To je manje unosno za marketing, ali znatno bolje potkrijepljeno dokazima.

Često postavljana pitanja

Trebam li uzimati probiotik?
Za specifičnu indikaciju s dokazima na razini soja, možda. Za opću dobrobit ili raspoloženje, dokazi ne opravdavaju cijenu.
Koloniziraju li probiotici moje crijevo?
Uglavnom ne. Većina prolazi kroz crijevo i nestaje u roku od nekoliko dana od prekida uzimanja, zbog čega učinci rijetko nadživljavaju suplementaciju.
Je li jogurt jednako dobar?
Za žive kulture, usporedivo i jeftinije. Fermentirana hrana ima svoju vlastitu bazu dokaza koja se tek razvija.
Što je s transplantacijom fecesa?
Zaista učinkovita za rekurentnu infekciju C. difficile. Sve ostalo je eksperimentalno.
