In today’s world, it seems like everything we consume is tainted with microplastics, harmful chemicals, or other undesirable substances. Unfortunately, the delightful experience of sipping on bubble tea has now joined that list.
Recent investigations by Consumer Reports have uncovered traces of lead in tapioca pearls from popular brands such as Gong Cha and Kung Fu Tea, as well as in packaged products from Trader Joe’s and WuFuYuan. Although none of the samples exceeded the official danger levels, three out of four were alarmingly close, suggesting that bubble tea should be an occasional indulgence rather than a daily habit.
Insights from Experts
James E. Rogers, PhD, director of food safety research and testing at Consumer Reports, stated, “These levels aren’t so high that we’d tell people to completely avoid bubble tea. But they’re high enough to make this an occasional treat, not an everyday drink.”
The root of the problem lies with cassava, the plant used to make those chewy pearls. Cassava naturally absorbs heavy metals from the soil, and lead contamination remains prevalent in many areas, making it easy for lead to end up in the final product. This issue extends to the tea, milk, or even the water used in preparation. In some instances, the liquid component of the drink contained more lead than the pearls themselves.
Evaluating the Health Impact of Bubble Tea
Lead exposure is cumulative, which is why health professionals emphasize its seriousness. Even small amounts can accumulate, posing risks especially to children and pregnant individuals, potentially impacting brain and nervous system development. Rogers advises, “It’s hard to avoid being exposed to some lead. That’s why it’s smart to minimize your exposure where you can.”
Following these findings, Trader Joe’s has withdrawn its Instant Boba Kit, and WuFuYuan is enhancing its safety protocols. The other companies have yet to respond.
While bubble tea isn’t lethal, it’s not a health food either. A large serving can contain between 300 to 500 calories and more sugar than a can of soda. Knowing there’s lead in your favorite Instagram-worthy drink might make it less appealing. Perhaps it’s best reserved as a weekend treat, and don’t forget to hydrate with some good old-fashioned water now and then.
