Can bubble tea cause kidney stones? Understanding the risks |
Bubble tea, also known as boba tea, has surged in popularity worldwide due to its unique combination of tea, milk, and chewy tapioca pearls. While it is a tasty treat, there are growing concerns about its potential impact on kidney health. Regularly drinking bubble tea, especially in place of water, can contribute to kidney stone formation when combined with certain dietary habits.A peer-reviewed study titled “Risk of Kidney Stones: Influence of Dietary Factors” published in Nutrients (2020) found that high consumption of oxalate-rich foods and beverages, along with insufficient hydration, significantly increases the risk of developing kidney stones. This underscores the importance of moderation and staying properly hydrated while enjoying bubble tea.
What are kidney stones, and how can bubble tea affect them
Kidney stones are hard mineral deposits that form in the kidneys and can vary in size. They often cause severe pain when passing through the urinary tract. Contributing factors include dehydration, high intake of oxalate-rich foods and drinks, excessive sodium, and insufficient calcium. Maintaining proper hydration and a balanced diet is crucial in preventing kidney stones, particularly for frequent bubble tea drinkers.
Bubble tea ingredients that could contribute to kidney stones
Bubble tea typically contains tea, milk or non-dairy creamer, sweeteners, and tapioca pearls. Each ingredient may influence kidney stone formation:
- Tea: Black tea is rich in oxalates, which, when consumed excessively, can contribute to kidney stones.
- Milk/Creamer: High calcium content in dairy may lead to calcium-based kidney stones if hydration is inadequate.
- Tapioca Pearls: Made from cassava, pearls can absorb heavy metals like lead from soil, adding potential kidney risks.
Bubble tea and kidney stones : Notable case studies
In Taiwan, a 20-year-old woman developed over 300 kidney stones after substituting water with bubble tea in her daily diet. This extreme case highlights how excessive bubble tea consumption can lead to severe kidney issues when hydration is insufficient.
Lead contamination in bubble tea and kidney stones risk
Some studies have detected lead in tapioca pearls used in bubble tea. Long-term exposure to lead, even at low levels, can affect kidney function and exacerbate stone formation. Choosing reputable bubble tea vendors and moderating intake can help minimise this risk.
Expert advice for reducing bubble tea-related kidney stones
Health experts recommend strategies to reduce kidney stone risk while enjoying bubble tea:
- Stay hydrated: Drink plenty of water alongside bubble tea to reduce stone formation risk.
- Moderation: Consume bubble tea as an occasional treat rather than daily.
- Diet balance: Limit oxalate-rich foods and ensure adequate calcium intake.
- Choose quality: Buy bubble tea from establishments that follow food safety standards.
Tips for enjoying bubble tea without increasing kidney stone risk
- Choose lower-sugar bubble tea options to support overall health.
- Use non-dairy alternatives to moderate calcium intake if prone to kidney stones.
- Avoid excessive artificial additives and flavourings.
- Alternate water intake between bubble tea servings to stay hydrated.
While bubble tea is a fun and popular beverage, excessive consumption can increase the risk of kidney stones, especially if it replaces daily water intake. Ingredients like black tea, milk, and tapioca pearls can contribute to mineral imbalances, and potential lead contamination adds another concern. By practising moderation, staying hydrated, and maintaining a balanced diet, bubble tea can still be enjoyed safely without putting kidney health at risk.Disclaimer: This article is for general informational purposes only and is not a substitute for professional medical advice, diagnosis, or treatment.
