How our sense of taste develops and adapts


In 1980, the candy company released a new gum aimed at children. Big League Chew sold a bag of crushed gum, which was to resemble chewing tobacco. It came with original flavors, grapes and sour apple.

Big League Chew was just one of many sweet treats enjoyed by children in the 1980s and 1990s. Another popular confectioner was the Nerds flavored sugar crystals coated with liquid corn syrup.

People who have grown up over these decades can have fond memories of these fragrances. But it is also unlikely that they will enjoy trying these sweets today. Taste receptors are designed to evolve and adapt to the environment, and our preferences change as we age. Scientists will learn more about our changing tastes, as well as what problems can arise when medications suppress our feelings.

How we taste

A person usually has about 10,000 taste buds located on their tongue as well as on the sides and roof of the mouth. In each taste bud there are separate cells, each of which has from 30 to 50 taste buds. These cells have a short lifespan and are replenished approximately every two weeks.

There are four main flavors that we can detect – bitter, salty, sour and sweet. Receptors for each of these flavors are located throughout the language. Until the 1990s, some scholars adhered to a “language map” which argued that parts of language were intended for specific tastes. It said that the tip of the tongue, for example, is more susceptible to sweet taste. However, studies have found that receptors for every taste are there spreads throughout the languageand the tympanic chord (anterior) and lingual-pharyngeal (posterior) nerves are responsible for mediating taste.

Activation products taste buds. When a person bites a salty roast, Na + enters the cell of taste buds, which releases transmitters. Just as bitter food as olives sends Ca2 + ions into the receptor cell.

The way we encode these tastes with meaning is an individual experience. Scientists have found that our coding process changes over time, and memory and perception shape it.

Flavors that develop

A child who ate the contents of their Halloween in one sitting is not doomed to be a sugar demon for life. Scientists have noticed this infants and toddlers show a strong preference for sweet taste. Once this advantage was an evolutionary advantage. Sugar from fruit or honey was a quick source complex carbohydrates. And sweet and ripe fruits gave the man more nutritional value.

The advantage of sweet weakens late adolescence. And older teens and people in their twenties find that they no longer care about Big League Chew grapes or strawberry nerds.

However, with age we become less dependent on the taste of food. Our memory and perception allow us to try and even love new products.

“As we grow and become acquainted with different flavors, we learn a lot. We associate different tastes with different consequences, ”says Nancy E. Rawson of the Monella Chemical Sense Center in Philadelphia.

One can, for example, learn that bitter taste is not harmful and that Brussels sprouts are really delicious when smoked with bacon dressing. This can push a person to try a more bitter taste. Conversely, feeling unwell after ingesting greased takito fat can push a person to avoid such foods in the future.

This evolving taste, says Rawson, allows a person to adapt to changes in the environment in which certain foods may be unavailable or new foods are introduced.

“Our senses are wonderful. They are constantly changing throughout our lives, ”says Rawson. “This allows the system to respond to the environment to encourage proper behavior.”

Just as our skin cells replenish less reliably as we age, Rawson says our taste buds also shrink over time. In women, taste buds begin to atrophy and decrease after forty years. For men, change begins at the age of fifty.

The sense of smell also weakens with age. Most of the taste sensations come from aroma, and the loss of that feeling can reduce a person’s pleasure. These changes, however, are gradual and insignificant. Rawson says a person can adapt and enjoy the taste of food and food during their senior years. The problem is when some medications interrupt taste buds.

Taste disorders

More than 250 drugs it is known that they affect smell or taste. These medications include antibiotics, drugs that lower cholesterol and blood pressure, and anti-inflammatory drugs. A person does not need a prescription to meet a drug that reduces taste. Fluticasone, an over-the-counter allergy medication, can cause olfactory and taste disturbances.

Various medications can also cause a person to have a metallic or bitter taste in their mouth. phantasy, or a sense of taste without irritants may be the result of taking many common medications. Biguanides, for example, are used to treat diabetes and may cause taste distortion. Even topical medications can have an effect. Dorzolamide eye drops, for example, are used to treat glaucoma. But they can create a bitter aftertaste in about 25 percent of users in the mouth.

Other drugs may make the taste harder to decipher. Produces its enalapril, which is used to treat high blood pressure as well as heart failure harder to taste sweets.

Studies show that there are consequences for people who no longer smell or taste food. While some are at risk of losing weight and suffering from malnutrition, studies have shown that people with muffled feelings in greater risk of obesity. The lack of delicate flavor encourages them to eat more or seek pleasure in eating more fat.

“I think it’s something that doctors aren’t set up for, but it can have a bigger impact on quality of life, diet and health,” Rawson says.
