- A study of 200 people has found that genes determine our sense of smell
- People worse at smelling certain scents also described them differently
- Certain people were more than 10,000 times better at detecting floral scents
The craving for beer or cheese could be hardwired for some – and it’s all to do with how we experience smell.
Scientists have discovered the genetic basis for why we smell a certain scent by examining the DNA of hundreds of individuals.
Richard Newcomb, a geneticist at the New Zealand Institute for Plant and Food Research, wanted to get to the bottom of why some people are revolted and attracted by certain smells.
Newcomb and his colleagues tested nearly 200 people for their sensitivity for ten different smells that are commonly found in foods.
The smells, which included malt, apple, blue cheese and violets, were added in small amount to one of three glasses of wine.
