I can remember a biology class where we made sugar and salt solutions and pipetted them onto different parts of our tongues to confirm the map was right.Īt the time it all seemed to make sense, but it turns out it’s not quite this simple. As the study period progressed, the researcher observed improvements in taste bud function in as little as two weeks.You probably remember the diagram from school – a pink tongue with different regions marked for different tastes – bitter across the back, sweet across the front, salty at sides near the front and sour at the sides towards the back. Initially, a high nicotine dependence correlated with a lower taste sensitivity in study participants. In one study from 2017, researchers explored changes in the perception of taste in smokers who quit smoking. The chemicals contained in cigarettes, such as carcinogens and alkaloids, can alter the receptors contained in your taste buds. Smoking can also negatively affect your sense of taste, among other harmful long-term effects. In addition, many of the illnesses and conditions we experience as we age – some of which have been listed above – can have a negative influence on our taste buds. The loss of smell that occurs with aging can also lead to a decrease in the sense of taste as we age. The taste buds that remain also experience a decrease in size and sensitivity, which can make it harder to perceive taste. The 10,000 taste buds we are born with begin to decrease as we move into middle age. Some of the common medications that cause dry mouth include:Īs we age, our taste buds not only diminish in number, but also change in function. Other medications may cause a change in taste by contributing to dry mouth, which makes it hard for the taste buds to recognize taste chemicals. The most common medications that affect your sense of taste are angiotensin-converting enzyme inhibitors, which are used to treat high blood pressure. Some medications may change your taste buds and alter your perception of taste. Some of the potential causes of nerve damage that can impact your sense of taste include: Nerve damage anywhere along this pathway, whether from injury or illness, can contribute to a change in your taste buds. Nerves found along the pathway from the mouth to the brain are responsible for taste bud function and the perception of flavor. Deficiencies in the following nutrients may lead to a loss of taste: Malnutrition can cause a deficiency in certain vitamins and minerals that are necessary for the taste buds to function properly. Ultimately, any medical condition that affects the brain, nose, or mouth can also result in a change to your taste buds. In addition, some non-nervous system disorders, such as cancer, can alter taste perception – especially during treatment. Nervous system disorders that affect the nerves of the mouth or brain, such as Parkinson’s disease, multiple sclerosis (MS), and Alzheimer’s disease, may cause a change in the perception of taste. These symptoms can reduce your sense of smell, which in turn can impact your perception of taste.Īlthough it may seem as if your taste buds have stopped working when you’re sick with a cold or the flu, the truth is that your sense of taste isn’t nearly as good without your sense of smell. Upper respiratory infections, whether viral or bacterial, can cause symptoms like nasal congestion and a runny nose. Your perception of flavor, especially via your taste buds, can be impaired by a variety of factors, from infections to medications, and more. These taste cells work in conjunction with chemical and physical senses to produce what we know as “flavor.”Ĭhanges in our taste buds can greatly affect the way we perceive flavor. When our taste buds encounter food and other substances, the taste cells inside send messages to the brain that help us make sense of what we are tasting. Our taste buds are responsible for helping us enjoy the many flavors the world has to offer.
