Based on expert insight, excessive boiling of tea, particularly in the context of milk tea, can potentially be unhealthy.
While the act of simply bringing water to a boil for brewing tea is standard and necessary, the reference provided specifically highlights concerns related to "over-boiling milk tea." This suggests that prolonged or intense boiling of the tea mixture after initial brewing can lead to negative health effects.
Why Excessive Boiling Might Be Unhealthy
According to Naidu:
- Nutrient Degradation: Over-boiling can degrade essential nutrients found in tea, such as vitamins and antioxidants. This diminishes the potential health benefits typically associated with drinking tea.
- Formation of Harmful Compounds: Excessive boiling may lead to the formation of harmful compounds. These compounds are linked to potential health concerns, including an increased risk of inflammation.
Therefore, the unhealthiness isn't in the initial boiling of water for brewing, but in the prolonged or over-boiling process applied to the tea itself (as noted in the context of milk tea).
Potential Health Impacts of Over-boiling
Based on the expert's statement, the potential negative impacts include:
- Reduced health benefits due to nutrient loss.
- Increased risk of inflammation.
- Other unspecified health concerns linked to the harmful compounds formed.
How to Avoid Potential Risks
To mitigate the potential risks associated with over-boiling:
- Follow Recommended Brewing Times: Brew tea according to standard guidelines, typically involving hot water but not prolonged boiling of the tea leaves/mixture itself.
- Avoid Excessive Simmering: If making beverages like milk tea, avoid letting the mixture boil vigorously or for extended periods after combining ingredients.
- Mind the Temperature: Once tea is brewed, keep it warm without subjecting it to continuous high heat or re-boiling.
By being mindful of brewing duration and temperature, you can help preserve the beneficial compounds in tea and avoid the potential formation of harmful ones.
