As a food science expert with a focus on the interaction between food chemistry and human physiology, I'm often asked about the sensations we experience when consuming certain foods. The numbness you feel when eating celery is a fascinating example of this interaction.
When you eat celery, you might experience a tingling or numbing sensation in your mouth. This sensation is not an allergic reaction, but rather a result of the natural compounds found in celery. The primary compound responsible for this effect is apioid, a type of compound that includes apiin, which is found in high concentrations in celery. Apiin is a phytochemical that has been shown to have various health benefits, including anti-inflammatory and antioxidant properties.

The numbing effect occurs because apiin and related compounds can interact with the sensory nerves in your mouth. When you chew celery, these compounds are released and can bind to the TRPA1 receptors on the nerves. TRPA1 is a type of protein that is activated by a variety of irritants, including certain natural chemicals found in foods. When apiin binds to these receptors, it triggers a response that you perceive as a tingling or numbing sensation.

It's important to note that this reaction is generally harmless and is not indicative of an allergy or any adverse health effect. In fact, some people enjoy the tingling sensation and seek out foods with similar effects, such as wasabi or certain types of peppers.

Regarding the claim that eating celery can help with tanning, there is no scientific evidence to support this. Tanning is primarily a result of the body's production of melanin in response to ultraviolet (UV) radiation from the sun or tanning beds. While it's true that some foods can potentially influence skin health and the way it responds to UV light, celery is not one of them. The notion that celery can enhance tanning is likely a myth and should not be taken as factual advice.

In summary, the numbing sensation you experience when eating celery is due to the interaction of apioid compounds with your sensory nerves, specifically the TRPA1 receptors. This is a natural and harmless phenomenon that some people find enjoyable. As for the tanning claim, it is not supported by scientific research and should be regarded as a misconception.
