Vanilla seems to have the most pleasing scent in the world, according to the new study.
Researchers tested different smells with 235 people from a variety of backgrounds, many of them from indigeneous populations who have little contact with Western culture.
Also well-liked was ethyl butyrate, a chemical that has a fruity odor and is used to enhance flavor in orange juice.
They found the least-liked smell was associated with isovaleric acid, found in foods such as cheese, soy milk and apple juice - as well as sweaty feet.
Researchers suggest there may be evolutionary survival reasons why humans prefer certain smells over others.
