Now I have something to blame when it comes to my craving for a bag of  taco flavored Doritos.

Remember back when life was simple and we only had four types of taste buds, sweet, sour, salt, and bitter? And then the '80s, we found out there was a fifth type, one that tasted savory flavors?

Well now it turns out we've had a sixth one all along. And the flavor it detects will not shock you. Scientists at Washington University in St. Louis have found we have a sixth taste bud that tastes fat.

The sensitivity of the fat taste bud varies a lot from person to person and could actually be one of the contributing factors to why some people are prone to eat less healthily than other people. But don't freak out just yet, more studies are coming!
