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].
So to define Umami as a single taste stimulated by a single factor, like sweet or salty, is incorrect and difficult to do. Umami is a taste that is stimulated by amino acids and nucleotides. It is a savory, mouth filling, brothy, flavor intensifier that you experience regularly but may have never identified.This is why I think of it as a three dimensional taste.mami on the other hand is the taste of amino acids, which is also very important to human life. Not only do our bodies produce it naturally but it is also found prolifically throughout nature, beginning with mother's milk.
