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 is a pleasant savoury taste produced by glutamate and ribonucleotides, chemicals which occur naturally in many foods including meat, fish and dairy products. Umami is subtle and not generally identified by people when they encounter it, but blends well with other tastes to intensify and enhance flavours.
