For generations, scientists thought the human tongue could detect only four basic tastes: sweet, sour, salt and bitter.
Then a fifth was discovered, "umami" or savoury. Now, researchers have identified a previously-unrecognised "sixth taste" – fat.
A team in the United States has located a chemical receptor in the taste buds on the tongue that recognises fat molecules, and found that its sensitivity varies between individuals.
The finding may help to explain why some people consume more fatty foods, as they are less aware of the taste as they eat.
The researchers hope their discovery can be exploited to combat obesity by increasing people's sensitivity to fat in their food.
