This Is How Much Taste You Lose While Eating On A Plane, According To Science

Airline food is historically known for being bland, but is it a matter of poor-quality meals or a physiological change due to a higher altitude?
---
The seemingly simple act of eating is far more complex than just putting food in our mouths. A significant, often overlooked component of that experience is taste – and how it's dramatically altered by the way we consume food, specifically whether we’re breathing through our nose or mouth. The article delves into this fascinating phenomenon, explaining why nasal breathing is crucial for a full appreciation of flavor and detailing the consequences when that pathway is blocked or compromised.
The core argument presented is that approximately 70-80% of what we perceive as “taste” isn’t actually taste at all; it's smell. True taste – the sensations of sweet, sour, salty, bitter, and umami – are detected by receptors on our tongue. However, these basic tastes provide only a rudimentary understanding of flavor. The vast majority of the nuanced and complex flavors we experience arise from volatile organic compounds (VOCs) released by food that travel through the nasal cavity to olfactory receptors high in the nose. This process is known as retronasal olfaction.
The article explains how this retronasal olfaction works. When you chew, these VOCs are released and ascend into your nasal passage. The olfactory receptors then send signals to the brain, which interprets them as flavor. When we breathe through our noses while eating, this process is optimized; a wider range of aromas reach the olfactory receptors, creating a richer, more complete sensory experience.
Conversely, when breathing through the mouth – whether due to nasal congestion from allergies, illness (like a cold or sinus infection), surgery, or even habitual behavior – these VOCs are largely blocked from reaching the olfactory system. This drastically reduces the perceived flavor of food. The article uses the analogy of eating something bland and then experiencing it as intensely flavorful after clearing your sinuses; this stark difference highlights the critical role of nasal breathing.
The impact isn't just about diminished enjoyment. The article points out that a significant reduction in taste perception can lead to several negative consequences. Firstly, it can diminish appetite and potentially contribute to malnutrition, particularly in vulnerable populations like children or the elderly who may already have reduced food intake. Secondly, it can alter dietary choices; individuals might gravitate towards foods with intense textures or high salt content to compensate for the lack of flavor, which could lead to unhealthy eating habits. Finally, a loss of taste pleasure can negatively impact overall quality of life and enjoyment of social gatherings centered around food.
The article explores various reasons why people might habitually breathe through their mouth. These include anatomical issues like deviated septums or enlarged adenoids, allergies that cause chronic nasal congestion, sleep apnea (which often leads to mouth breathing during sleep), and even learned behaviors developed as a coping mechanism for previous nasal obstructions. It emphasizes that habitual mouth breathing can also create a vicious cycle; it can alter facial structure over time, further contributing to breathing difficulties and perpetuating the problem.
The piece doesn't just focus on the negative aspects. It offers practical advice and potential solutions for improving taste perception. These include addressing underlying nasal congestion through allergy management or medical intervention (such as sinus surgery in severe cases). Mouth taping – a controversial technique where a person gently tapes their mouth shut during sleep to encourage nasal breathing – is mentioned, but with a cautionary note emphasizing the importance of consulting a healthcare professional before attempting it. Simple exercises to strengthen nasal passages and improve breathing patterns are also suggested.
Furthermore, the article touches upon how certain medical conditions and medications can affect taste perception independently of nasal breathing. Chemotherapy, for example, is known to alter taste buds directly, leading to a metallic or diminished sense of flavor. Certain medications can have similar side effects. Therefore, it’s crucial to consider all potential factors contributing to altered taste.
Ultimately, the article serves as an eye-opening exploration into the intricate relationship between smell and taste. It underscores that what we commonly refer to as "taste" is largely a product of our sense of smell, and highlights the importance of nasal breathing for experiencing food in its full complexity. By understanding this connection, individuals can take steps to address any underlying issues hindering their ability to fully appreciate the flavors around them, potentially improving both their health and overall enjoyment of life’s simple pleasures – like savoring a delicious meal.
