All students learn early in their educations about the human body's five senses. Sight, smell, hearing, and touch constitute the first four. Taste is one of the five corporeal senses too. There are six generally recognized taste factors that combine to create flavor sensations, with some controversy about the inclusion of the fat taste or the piquant (spicy) taste, which may be a feeling more
. than a taste. The sensation of taste originates in the taste buds on the tongue, however the olfactory senses also contribute to the overall experience. The purpose of taste is to help identify the characteristics of any given food. The sweet detectors Indicate ripe fruit and carbohydrates. Sweetness is determined by the presence of various sugars including sucrose, fructose, and glucose. Some sweet foods include honey, mangoes, carrots, milk and dates.The salty taste buds discover the presence of NaCl (salt) and other minerals. Saltiness is a measure of sodium content. Potato chips, packaged processed meals, table salt, cheeses and bacon all trigger the salty taste buds. The third type of taste bud, the bitter one, Identifies poisonous or overripe leaves. For this reason, it is the most sensitive of tastes for its role in protecting tasters from possible poisons. Some bitter foods include coffee, unsweetened cocoa, citrus peel, uncured olives and quinine which is used in tonic water as well as to quantify bitterness. Sour taste makes its way into the fourth position of taste buds and Indicates acidic materials including unripe fruits which can serve as sources of certain vitamins. Some sour foods include lemons, tamarinds, spoiled milk, green apples and vinegar. The tongue's fat hunters Identify the presence of dietary lipids, an important source of stored energy. Some foods with dietary lipids include avocados, So, although taste is one of the five senses, it has subheadings within it, making the tongue a whole study of its own.
