Qhov no tsis muaj tseeb. Cov tub lag luam tsuas yog ua tus nqi siab gimmicks. Txawm hais tias qee tus neeg sawv cev fermenting tau ntxiv ntau yam "probiotics", muaj kev sib tw ntawm cov kab sib txawv, thiab feem ntau cov probiotics hauv cov txheej txheem fermentation tsis tuaj yeem pab tab sis tuag. Qhov thib ob, kev sib xyaw ua ke ntawm ntau yam kab mob tsis ua rau yogurt "kev noj zaub mov zoo dua", thiab qhov cuam tshuam rau qhov tsw ntawm cov kua mis nyeem qaub kuj tseem txwv.
