* Dairy products, including cheese, contain proteins that bind to the olfactory receptors in the nose. This binding can block other scents from being detected, which can make it difficult to distinguish between different smells.
* Cheese also contains strong aromatic compounds that can overpower other scents.
* Cheese can also create a build up of mucus in the nasal cavity, which can cause a stuffy nose and make it harder to identify scents.
