The sense of taste is found in our language. That's for sure you'll know. But do you know what part of the tongue receives each of the flavors of food and drink we eat? Find out some curious facts in the following article.
The sensation produced by the sense of taste is called taste. Foods have different tastes: sweet, salty, acidic or bitter. There are also combinations between them. Detects which is the preponderant taste is work of the taste buds, located in the mouth.
How do we receive the flavors of the meals?
Beyond being salty or sweet, bitter or acidic (and a fifth flavor to be discussed later), the taste buds select which foods to eat according to nutritional needs and personal desires.
If you are used to eating a salty snack at 7pm every day, your mouth will begin to send signals to the brain Just at that time of the day. But attention, you will not want to eat something sweet, but something salty.
The taste acts thanks to soluble chemical substances located on the tongue. It is said that those Civilizations where they consume foods with more ingredients and spices have more developed the sense of taste . This occurs, for example, in countries such as India, Japan or Mexico.
There are three types of taste buds
Fungiform Papillae: They are found on the lateral borders of the tongue and on the front of the back. They are mushroom-shaped and sensitive to salty, acidic and sweet flavors.
Goblet or lenticular papillae : They are distributed in the base of the tongue as if they were a"V", have a cup or chalice shape and capture only the flavors Bitter .
Filiform or tapered papillae: They are located at the tip of the tongue and on the sides and are shaped like filaments. They do not have a gustatory function, but they capture the temperature and the textures of the foods.
Diseases related to the sense of taste (not very frequent or taken into account) are:
Ageusia : Reduction or loss of the sense of taste, is related to certain pathologies like diseases that affect the smell, burns in the language Or facial paralysis.
Dysgeusia : Distorts the taste of food and drink. It is a symptom of depression .
Hypogeusia: The person who has it has little ability to taste and differentiate the four basic flavors of food and liquids.
One of the strange disorders related to the taste for food is called"neophobia"and it is suffered especially by children of 3 years, who do not want to try new tastes. It usually appears in small ones that do not eat varied or base their diet on only a handful of foods. Because of the fast food and lack of vegetables in the dishes, more and more are the small ones who suffer from this fear of eating new things. It is not always a whim, therefore it is vital to treat it accordingly.
The map of the language and the flavors
The language could be divided into different sectors, depending on where the detection of each flavor is located. Similarly, some researchers indicate that this is a myth and that the whole language has the capacity to enjoy the tastes of the foods .
The language map was created by a Harvard psychologist named Edwin Boring. According to this professional, The tip of the tongue detects the sweet taste, the anterior sides, the salty taste; The back, the bitter taste; And the later sides, acid taste. What the report actually indicates is that this buccal muscle has more or less sensitive areas for a particular flavor.
The theory can be tested by placing a little salt on the tip of the tongue, for example. In 1974 this theory was denied after several investigations. The most important review was done by Dr. Virginia Collings of the University of Pittsburgh (United States), who indicated that The variation in each region of the tongue in relation to tastes was not significant.
Later, in the year 2000, it was"discovered"that there was a fifth taste or taste in the tongue. Is called Umami And is present in the proteins of the salty food, such as algae or bacon. Some say it is not that we did not develop it before, but that it"woke up"when food began to have a specific ingredient, called monosodium glutamate. This component is found in some naturally occurring foods, such as celery, spinach , Mushrooms and green tea, but in lower and not so concentrated measures.
In 2010, at the University of Deakin (Australia), Detected that we have a sixth taste that is detected in the tongue . It is fat. It is not strange to think of this theory if we consider the diet that many people in the world, full of fried and greasy substances (especially for fast food). The study also concluded that people with obesity had more developed this taste"fat"on their tongue than patients with a normal body mass index.
Thus, the map of the language would be formed by six different tastes: The four"primaries", ie, sweet, bitter, salty and sour and modern or new, umami and grease .
