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].
Scientists have debated whether umami was a basic taste since Kikunae Ikeda first proposed its existence in 1908. In 1985, the term umami was recognized as the scientific term to describe the taste of glutamates and nucleotides at the first Umami International Symposium in Hawaii.
