The COVID-19 pandemic has brought about a multitude of unexpected symptoms, from the loss of smell and taste to the infamous “COVID tongue.” But have you ever wondered, does food taste salty with COVID? As it turns out, many people who have contracted the virus have reported experiencing a sudden and intense salty taste in their mouths, even when consuming foods that are normally sweet or neutral-tasting. In this article, we’ll delve into the science behind this phenomenon and explore the possible reasons why food might taste salty with COVID.
Understanding the Science of Taste
Before we dive into the specifics of COVID-related salty taste, it’s essential to understand how our sense of taste works. The human tongue contains small bumps called papillae, which house taste buds. These taste buds contain specialized cells called taste receptors, 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, triggering a signal that is sent to the brain. The brain then interprets this signal as a specific taste. For example, when we eat something sweet, the molecules bind to the sweet receptors, and our brain registers the taste as sweet.
The Impact of COVID-19 on Taste Buds
Research has shown that COVID-19 can affect the sense of taste in several ways. The virus can damage the taste buds on the tongue, leading to a decrease in the number of functional taste receptors. This can result in a reduced ability to detect certain tastes, including sweet and sour.
Additionally, COVID-19 can cause inflammation in the mouth and throat, leading to the production of pro-inflammatory cytokines. These cytokines can alter the functioning of the taste buds, making them more sensitive to certain tastes, including salty.
The Role of ACE2 Receptors in COVID-19-Related Taste Changes
ACE2 receptors are proteins found on the surface of many cells, including those in the tongue and mouth. These receptors play a crucial role in the regulation of taste and are also the primary entry point for the COVID-19 virus.
When the virus binds to ACE2 receptors, it can trigger a cascade of events that lead to changes in the functioning of the taste buds. This can result in an increased sensitivity to salty tastes, as well as a decreased ability to detect other tastes.
The Salty Taste Phenomenon: What’s Behind It?
So, why do some people experience a salty taste with COVID? There are several theories, including:
- Increased production of pro-inflammatory cytokines: As mentioned earlier, COVID-19 can cause inflammation in the mouth and throat, leading to the production of pro-inflammatory cytokines. These cytokines can alter the functioning of the taste buds, making them more sensitive to salty tastes.
- Damage to the taste buds: The virus can damage the taste buds on the tongue, leading to a decrease in the number of functional taste receptors. This can result in a reduced ability to detect certain tastes, including sweet and sour, and an increased sensitivity to salty tastes.
- Changes in the oral microbiome: The oral microbiome plays a crucial role in the regulation of taste. COVID-19 can disrupt the balance of the oral microbiome, leading to changes in the way we perceive tastes, including an increased sensitivity to salty tastes.
Other Factors That May Contribute to the Salty Taste Phenomenon
While the exact mechanisms behind the salty taste phenomenon are still not fully understood, several other factors may contribute to its development. These include:
- Medications: Certain medications, such as antihistamines and decongestants, can alter the sense of taste and contribute to the development of a salty taste.
- Nutritional deficiencies: Deficiencies in certain nutrients, such as zinc and vitamin B12, can affect the sense of taste and contribute to the development of a salty taste.
- Underlying medical conditions: Certain medical conditions, such as gastroesophageal reflux disease (GERD) and sinus infections, can affect the sense of taste and contribute to the development of a salty taste.
What Can You Do If You’re Experiencing a Salty Taste with COVID?
If you’re experiencing a salty taste with COVID, there are several things you can try to alleviate the symptom:
- Stay hydrated: Drinking plenty of water can help to thin out mucus and reduce inflammation in the mouth and throat.
- Use a humidifier: Dry air can exacerbate the salty taste phenomenon. Using a humidifier can help to add moisture to the air and reduce the symptom.
- Avoid spicy or acidic foods: These types of foods can irritate the mouth and throat, making the salty taste worse.
- Try salt-free seasonings: If you’re finding that the salty taste is affecting your ability to enjoy food, try using salt-free seasonings to add flavor to your meals.
When to Seek Medical Attention
While a salty taste with COVID is usually a temporary symptom that resolves on its own, there are certain situations in which you should seek medical attention. These include:
- Severe symptoms: If you’re experiencing severe symptoms, such as difficulty swallowing or breathing, seek medical attention immediately.
- Persistent symptoms: If your symptoms persist or worsen over time, seek medical attention.
- Underlying medical conditions: If you have an underlying medical condition, such as diabetes or heart disease, seek medical attention if you’re experiencing a salty taste with COVID.

Does COVID-19 affect our sense of taste?
COVID-19 can indeed affect our sense of taste. Many people who have contracted the virus have reported experiencing changes in their sense of taste, including a reduced ability to taste sweet, sour, and salty flavors. This is often referred to as ageusia, which is a temporary loss of taste. In some cases, people may experience a metallic or bitter taste in their mouth, which can be unpleasant.
The exact reason why COVID-19 affects our sense of taste is not fully understood, but it is thought to be related to the way the virus interacts with the cells in our tongue and mouth. The virus may damage or alter the function of the taste buds, leading to changes in the way we perceive different flavors. Fortunately, in most cases, the loss of taste is temporary and resolves on its own once the infection has cleared.
Why does food taste salty with COVID-19?
Some people who have contracted COVID-19 have reported that food tastes salty, even if it doesn’t contain a lot of salt.
