Cov chaw tsim khoom lag luam, muaj cov nroj tsuag rau cov neeg siv tshuaj pleev kom huv thiab kev ua kom huv si, yog li kom mus txog qib ntawm cov dej haus, tab sis tus nqi yog kim.
Yashi cov ntaub hoob nab yog 100% tsis siv tshuaj chiv thiab tshuaj tua kab. Tag nrho cov txheej txheem admts lub cev lim dej thiab cov tshuaj lom neeg uas tsis muaj tshuaj lom thiab cov tshuaj tua kab, thiab lwm yam. Nws tsis muaj tshuaj lom thiab cov teeb meem cov ntsiab lus thiab cov carcinogens. Siv nws muaj kev nyab xeeb dua thiab cov neeg siv khoom tau txais txiaj ntsig ntau dua.
