The idea that green tea or matcha could be better suited to Koreans or those of East Asian descent compared to coffee is an interesting theory, and there are a few factors worth exploring:
1. Cultural and Historical Context:
Green tea has a long history in East Asia, particularly in countries like China, Japan, and Korea, where it has been consumed for centuries as part of daily life. This longstanding cultural connection might mean that people from these regions are more familiar with green tea, both in terms of taste preferences and its effects on the body. In contrast, coffee has a shorter history in East Asia and is more deeply associated with Western cultures. It’s possible that the historical consumption of green tea has led to generational familiarity and adaptation to its properties.
2. Genetic Factors and Caffeine Sensitivity:
There’s some evidence that genetic differences influence how individuals metabolize caffeine. Studies suggest that people of East Asian descent may have a higher prevalence of slow caffeine metabolism due to specific genetic variants, such as those affecting the enzyme CYP1A2, which breaks down caffeine. This could mean that coffee, which generally contains more caffeine than green tea or matcha, might lead to more pronounced effects like jitteriness or insomnia in people with this slower metabolism. Green tea, which has a lower caffeine content and also contains L-theanine, may offer a more balanced, calming effect for these individuals.
3. Health Benefits and Metabolic Response:
Green tea and matcha contain a unique combination of caffeine and L-theanine, an amino acid known to promote relaxation and reduce stress without causing drowsiness. This could result in a smoother energy boost compared to coffee, which lacks significant amounts of L-theanine and can cause spikes and crashes in energy levels. Additionally, green tea is rich in antioxidants, particularly catechins like EGCG, which have anti-inflammatory and protective health benefits. Some studies suggest that certain populations, including East Asians, may metabolize these antioxidants more effectively due to genetic factors.
In contrast, while coffee also has health benefits—such as antioxidants and potential protection against diseases like Parkinson’s and Type 2 diabetes—it can sometimes be harsher on the stomach and cause digestive issues or anxiety in individuals who are more sensitive to caffeine or acidic beverages.
4. Traditional Medicinal Beliefs:
In East Asian cultures, green tea has been valued for its medicinal properties, such as promoting digestion, improving concentration, and enhancing detoxification. These traditional beliefs may have guided generations to see green tea as not just a beverage but a health-supporting element. This ingrained cultural and medicinal significance could make green tea or matcha more psychologically and physically suited to people of East Asian descent.
5. Personal Preference and Dietary Habits:
People of East Asian descent, especially those living in or closely connected to East Asian cultures, may simply have a dietary preference for green tea due to its ubiquitous presence in their food culture. This preference may result in a better tolerance or enjoyment of green tea over coffee. Over time, such preferences may even be reinforced by lifestyle factors or individual health benefits observed from green tea consumption.
Conclusion:
While it’s difficult to say definitively that green tea or matcha is inherently “better†for Koreans or those of East Asian descent than coffee, there are several factors—cultural familiarity, genetic differences in caffeine metabolism, and the calming effect of L-theanine—that could make it a more suitable or enjoyable option for some individuals. However, the preference between green tea and coffee will always be a personal and lifestyle-based decision, influenced by individual genetics, health goals, and cultural connections.

The question of whether drinking green tea or matcha is better suited to Koreans or individuals of East Asian descent compared to coffee can be approached from cultural, genetic, and physiological perspectives.
Cultural Factors:
• Historical Consumption: Green tea has been an integral part of East Asian cultures, including Korea, for centuries. It is deeply embedded in social rituals, traditional medicine, and daily life. This long-standing tradition might make green tea more familiar and preferred among individuals from these cultures.
• Dietary Habits: Regular consumption from a young age could lead to a developed palate that prefers the taste of green tea over coffee. Additionally, traditional diets might be more harmonious with the compounds found in green tea.
Genetic and Physiological Factors:
• Caffeine Metabolism: Some studies suggest genetic variations in enzymes like CYP1A2, which is involved in caffeine metabolism. However, these variations are widespread globally and not confined to any specific ethnic group. Therefore, it’s not conclusive that East Asians metabolize caffeine differently in a way that would make green tea more suitable than coffee.
• Sensitivity to Compounds: Green tea contains L-theanine, an amino acid that promotes relaxation without drowsiness. This, combined with caffeine, can lead to a calm alertness. If individuals of East Asian descent have a cultural or genetic predisposition to prefer this state, they might favor green tea.
Health Considerations:
• Antioxidant Intake: Green tea is rich in catechins like EGCG, which have antioxidant properties. While beneficial for health, the degree of benefit does not significantly differ based on ethnicity.
• Lactose Intolerance: Higher prevalence of lactose intolerance in East Asian populations might make dairy-heavy coffee beverages less suitable, indirectly making green tea a more comfortable choice.
Conclusion:
While cultural familiarity and dietary habits make green tea or matcha a preferred beverage in Korean and East Asian societies, there is limited scientific evidence to suggest that it is inherently better suited on a genetic or physiological level compared to coffee. Personal preference, cultural practices, and individual health considerations play more significant roles in determining suitability.
