Question
Answer the following question.
Why do we get bad breath after eating garlic or raw onion?
Advertisements
Solution
- Raw onion and garlic contain volatile sulphur-containing compounds.
- Sulphur-containing compounds have a distinctive odour which remain in the mouth after consumption of onion and garlic.
- Also, volatile compounds (like certain sulphur containing compounds) in foodstuffs are generally excreted through the lungs and may result in bad breath.
