Humans have a special taste for fat

Move over sweet and salt: Researchers said people have a distinct and basic taste for fat, too.

They propose expanding the taste palate to include fat along with sweet, salty, bitter, sour and relative newcomer umami.

A research team at Purdue University tested look-alike mixtures with different tastes. More than half of the 28 special tasters could distinguish fatty acids from the other tastes.

Nutrition science professor Richard Mattes said the fat taste isn't exactly good, even though people gobble up lots of it. They propose calling the taste 'oleogustus' after Latin for fat taste.
