Why Does Olive Oil Burn My Throat?
Introduction
If olive oil burns your throat, it's important to understand the potential causes behind this sensation. This burning can be attributed to several factors, including polyphenols, acidity, allergic reactions, and temperature.
Understanding the Burning Sensation
The burning sensation when consuming olive oil can be caused by its polyphenols, high levels of which can produce a peppery or pungent flavor. These compounds are found in high-quality, fresh olive oil and can sometimes irritate the throat. In addition, the acidity of olive oil, although typically present in lower levels in premium oils, can also contribute to throat irritation. For those with certain sensitivities, an allergic reaction to olives or olive oil can cause a burning sensation or throat irritation. Furthermore, consuming olive oil at higher temperatures, especially when heated, can exacerbate throat irritation.
Identifying the Cause
If you experience severe or persistent burning associated with olive oil, it's advisable to consult a healthcare professional. They can help rule out any underlying health issues such as gastroesophageal reflux disease (GERD). Persistent symptoms might also indicate that the oil has gone rancid. It's crucial to discard any olive oil that shows signs of spoilage to prevent further irritation.
The TRPA1 Molecule and Its Role
A recent study published in the Journal of Neuroscience revealed that the burning sensation experienced when consuming high-quality olive oil is due to a specific physiological mechanism. The study highlighted the presence of a molecule called TRPA1 in the upper throat and nose, but not in the mouth or tongue. TRPA1 binds to a substance called oleocanthal, which is found in olive oil, particularly in extra-virgin olive oil.
These findings explain why some people experience a strong burning sensation, even coughing, when consuming high-quality olive oil. The more potent the dose of oleocanthal, the more intense the burning sensation. This discovery not only sheds light on the sensory experience of olive oil but also has broader implications for understanding the effects of pain medications, as there is a striking similarity between the burning sensation caused by oleocanthal and that of ibuprofen.
Making the Most Out of Olive Oil
For those who enjoy the complex flavors of extra-virgin olive oil, understanding how to taste and appreciate it can enhance your culinary experience. During a series of Olive Oil Chef dinners at Lina’s Italian Market, I had the opportunity to taste some high-end olive oils and learn about the physiological reasons behind the burning sensation. This experience not only makes the sensory experience of olive oil more enjoyable but also demonstrates the importance of using and storing olive oil properly to avoid any negative reactions.
