The notion that most Korean people don’t have armpit odour might seem surprising, but scientific research reveals a fascinating genetic basis for this phenomenon. This blog post will explore the science behind this intriguing observation.
At the heart of the matter lies the ABCC11 gene, which plays a pivotal role in producing the compounds responsible for underarm odour. Studies have shown that most East Asians, including Koreans, have a specific mutation in this gene that significantly reduces their body odour production. This genetic difference sets them apart from other populations where this mutation is less prevalent.
The impact of this genetic variation is striking. Research at the University of Bristol discovered that a mere 0.006% of the Korean population carries the ABCC11 gene variant associated with armpit odour. This remarkably low percentage underscores the widespread nature of this genetic trait among Koreans.
The consequences of this genetic predisposition are evident in Korean society. Deodorant, a staple in many Western cultures, is not commonly found in Korea. This reflects the fact that most Koreans don’t experience the same degree of body odour as people from other ethnic groups.
However, it’s crucial to acknowledge that genetics isn’t the sole determinant of body odour. While a significant portion of Koreans might possess the “odourless” gene variant, individual hygiene practices still hold importance. Factors such as diet, exercise, and overall hygiene can influence body odour to some extent.
Moreover, societal norms and personal preferences can also play a role. Some individuals, even those genetically predisposed to less body odour, might opt to use deodorant due to social expectations or personal comfort.
In conclusion, the scientific evidence strongly suggests that the low prevalence of armpit odour among Koreans is primarily attributable to a specific genetic mutation. This fascinating genetic quirk offers a compelling example of how human biology can vary across populations, leading to intriguing differences in traits and characteristics.
