How to prevent bad breath after eating?

When I eat stuff like cheese, my breath stinks really bad afterwards. I’ve tried mints but it doesn’t really help. Sometimes my tongue goes slightly yellow too. What’s going on? Anything I can do? thanks.

Get those oral-B brush ups!
Floss and use mouthwash.
try chewing gum

How can I prevent from my bad breath?

It is too much even when I brush my teeths and after 5 minutes again that bad breath and I am using mouth wash but nothing happened but when I am eating something so on that time my bad breath is getting a little bit better but not it will not finish SO PLEASE IF YOU GUYS KNOW HOW TO HUNDLE WITH IT PLEASE TELL ME EXACTLY WHAT SHOULD I DO?

make sure you are not using mouthwash with alcohol in as this makes the problem worse (may also be written as ethanol) Make sure you are not eating protein -meat, cheese, eggs, pulses, beans etc, more than twice a day, make sure you are not constipated, make sure you do not have gum disease, make sure you drink enough,
