A normal heart rate is 60 to 100 beats per minute at rest. Ventricular tachycardia is a regular, faster-than-normal heart rate that begins in the heart's lower chambers.
Umami (pronounced oo-MAH-mee) has been called the fifth taste, joining the traditional quartet of salty, sweet, bitter and sour. The word umami derives from the Japanese umai, which roughly translates as deliciousness [source: Umami Information Center]. Chefs have described it as everything from delicate and subtle to earthy, musty and mushroom-like [source: Ninomiya].
Umami, or savory, is the taste you get from glutamate, which is found in chicken broth, meat extracts, and some cheeses. A common misconception is that taste cells that respond to different tastes are found in separate regions of the tongue. In humans, the different types of taste cells are scattered throughout the tongue. Taste quality is just one way that you experience a certain food.
