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].
In fact, there's more to taste than sweet, sour, salty and bitter. Most scientists agree that there's a fifth distinct taste, called umami, identified by a Japanese scientist named Kikunae Ikeda in the early 1900s (and ignored by the West for most of the twentieth century). This is the taste of glutamate.
