The COVID-19 pandemic has brought about a multitude of changes in our daily lives, from the way we work and socialize to the way we experience the world around us. One of the lesser-known effects of the virus is its impact on our sense of taste. Many people who have contracted COVID-19 have reported changes in their sense of taste, with some experiencing a complete loss of taste, while others have reported a metallic or bitter taste in their mouths.
Understanding the Science Behind COVID-19 and Taste
To understand how COVID-19 affects our sense of taste, it’s essential to delve into the science behind it. Our sense of taste is mediated by taste buds on our tongues, which contain specialized cells called taste receptors. These receptors are responsible for detecting the five basic tastes: sweet, sour, salty, bitter, and umami.
When we eat or drink, molecules of the substance bind to the taste receptors on our tongues, sending signals to our brains, which interpret these signals as specific tastes. However, COVID-19 can disrupt this process in several ways.
How COVID-19 Affects the Sense of Taste
Research has shown that COVID-19 can affect the sense of taste in several ways:
- Inflammation of the tongue and mouth: COVID-19 can cause inflammation of the tongue and mouth, leading to a decrease in the number of taste buds and a disruption in the way they function.
- Damage to the olfactory system: The olfactory system, which is responsible for our sense of smell, is closely linked to our sense of taste. COVID-19 can damage the olfactory system, leading to a decrease in our ability to taste.
- Changes in the way the brain processes taste information: COVID-19 can also affect the way the brain processes taste information, leading to changes in the way we perceive tastes.
What Do People Experience When Their Sense of Taste is Affected by COVID-19?
People who have contracted COVID-19 and experienced changes in their sense of taste have reported a range of symptoms, including:
- A complete loss of taste
- A metallic or bitter taste in the mouth
- A decrease in the intensity of tastes
- A distortion of tastes, with sweet tastes tasting sour or salty
These symptoms can be distressing, especially for people who enjoy food and drink. However, it’s essential to note that these symptoms are usually temporary and resolve on their own once the infection has cleared.
What Foods and Drinks Are Affected by COVID-19?
While COVID-19 can affect the sense of taste in general, some foods and drinks are more likely to be affected than others. These include:
- Sweet foods and drinks: Many people who have contracted COVID-19 have reported that sweet foods and drinks taste bitter or metallic.
- Sour foods and drinks: Sour foods and drinks, such as citrus fruits and vinegar-based dressings, can be particularly affected by COVID-19, with some people reporting that they taste sweet or bland.
- Umami-rich foods: Umami-rich foods, such as meats and mushrooms, can be affected by COVID-19, with some people reporting that they taste bitter or metallic.
How to Manage Changes in Taste Caused by COVID-19
While changes in taste caused by COVID-19 can be distressing, there are several ways to manage them. These include:
- Staying hydrated: Drinking plenty of water can help to keep the mouth moist and reduce the severity of taste changes.
- Eating foods that are easy to taste: Foods that are high in flavor, such as spicy or sour foods, can be easier to taste than bland foods.
- Using herbs and spices: Herbs and spices can add flavor to food without being too overwhelming.
- Trying different temperatures: Some people find that eating foods at different temperatures can help to stimulate the sense of taste.
When to Seek Medical Attention
While changes in taste caused by COVID-19 are usually temporary and resolve on their own, there are some instances where medical attention may be necessary. These include:
- Persistent changes in taste: If changes in taste persist for more than a few weeks, it’s essential to seek medical attention to rule out any underlying conditions.
- Severe changes in taste: If changes in taste are severe and interfere with daily life, it’s essential to seek medical attention.
- Other symptoms: If changes in taste are accompanied by other symptoms, such as a fever or difficulty swallowing, it’s essential to seek medical attention.
Conclusion
COVID-19 has brought about many changes in our daily lives, including changes in the way we experience the world around us. One of the lesser-known effects of the virus is its impact on our sense of taste. While changes in taste caused by COVID-19 can be distressing, they are usually temporary and resolve on their own once the infection has cleared. By understanding the science behind COVID-19 and taste, and by managing changes in taste, we can reduce the impact of the virus on our daily lives.
| Food/Drink | Commonly Reported Taste Changes |

| Sour foods and drinks | Sweet or bland taste |
| Umami-rich foods | Bitter or metallic taste |
In conclusion, while COVID-19 can change the taste of foods and drinks, these changes are usually temporary and can be managed with some simple strategies. By staying hydrated, eating foods that are easy to taste, using herbs and spices, and trying different temperatures, we can reduce the impact of COVID-19 on our sense of taste.
What is the relationship between COVID-19 and taste loss?
COVID-19 has been found to affect the sense of taste in many individuals. Research suggests that the virus can damage the taste buds on the tongue, leading to a temporary or, in some cases, permanent loss of taste. This is often accompanied by a loss of smell, as the two senses are closely linked.
Studies have shown that the virus can bind to the ACE2 receptors found on the surface of taste bud cells, leading to inflammation and damage. This damage can result in a reduced ability to detect sweet, sour, salty, and bitter tastes. In some cases, people may experience a metallic or unpleasant taste in their mouth.
How common is taste loss in COVID-19 patients?
Taste loss is a relatively common symptom of COVID-19, with studies suggesting that up to 80% of patients experience some degree of taste impairment. However, the severity and duration of taste loss can vary widely from person to person. Some people may experience a mild loss of taste that resolves on its own within a few days, while others may experience a more severe loss of taste that persists for weeks or even months.
In general, taste loss is more common in people with more severe cases of COVID-19, such as those who require hospitalization. However, even people with mild cases of the virus can experience taste loss, and it is not uncommon for people to experience a loss of taste before other symptoms of the virus appear.
What are the different types of taste loss associated with COVID-19?
There are several different types of taste loss that can be associated with COVID-19. Some people may experience a complete loss of taste, while others may experience a partial loss of taste or a distortion of taste. For example, some people may find that sweet tastes are more pronounced, while others may find that sour tastes are more intense.
In addition to these changes in taste perception, some people may also experience a condition known as parosmia, in which familiar smells and tastes are distorted or unpleasant. For example, a person with parosmia may find that the smell of coffee or the taste of chocolate is suddenly unpleasant or metallic.
How long does taste loss typically last in COVID-19 patients?
The duration of taste loss in COVID-19 patients can vary widely, but in most cases, it is temporary and resolves on its own within a few weeks. Studies have shown that the majority of people who experience taste loss due to COVID-19 will recover their sense of taste within 2-4 weeks.
However, in some cases, taste loss can persist for longer periods of time. Some people may experience a prolonged loss of taste that lasts for several months, while others may experience a permanent loss of taste. In these cases, it is often necessary to seek medical attention to rule out other underlying causes of taste loss.
Can taste loss be a symptom of long COVID?
Yes, taste loss can be a symptom of long COVID, also known as post-acute COVID-19 syndrome (PACS). Long COVID is a condition in which symptoms of COVID-19 persist for weeks or months after the initial illness has resolved. Taste loss is one of the many symptoms that can be associated with long COVID, along with fatigue, muscle pain, and cognitive impairment.
In some cases, people with long COVID may experience a persistent loss of taste that lasts for months or even years. This can have a significant impact on quality of life, making it difficult to enjoy food and other activities that rely on the sense of taste.
Is there any treatment for COVID-related taste loss?
There is currently no specific treatment for COVID-related taste loss, but there are several things that people can do to help manage their symptoms. For example, people can try to eat foods that are high in flavor, such as spicy or sour foods, to help stimulate their sense of taste.
In addition, some people may find it helpful to try zinc supplements, as zinc is an essential mineral that plays a role in the health of the taste buds. However, it is always best to talk to a healthcare provider before starting any new supplements or treatments.
Can COVID-related taste loss be prevented?
There is currently no surefire way to prevent COVID-related taste loss, but there are several things that people can do to reduce their risk. For example, people can take steps to reduce their risk of contracting COVID-19, such as wearing a mask, washing their hands frequently, and avoiding close contact with others.
In addition, people can take steps to support the health of their taste buds, such as eating a balanced diet that is rich in fruits, vegetables, and whole grains. Getting enough sleep and managing stress can also help to support the health of the taste buds and reduce the risk of taste loss.
