Question
Why do we get bad breath after eating garlic or raw onion?
✓

Answer

  1. Raw onion and garlic contain volatile sulphur-containing compounds.
  2. Sulphur-containing compounds have a distinctive odour which remain in the mouth after consumption of onion and garlic.
  3. Also, volatile compounds (like certain sulphur containing compounds) in foodstuffs are generally excreted through the lungs and may result in bad breath.
