A trendy drink that’s become a social media favorite may now have fans thinking twice, after questions were raised about one key ingredient.

<h2><span rel="noindex">Boba Tea</span> Contains Lead?</h2>

Bubble tea, the Taiwanese drink made of black tea, milk, sugar, and chewy tapioca pearls, has won fans worldwide since its debut in the 1980s. But recent findings suggest it may deserve a closer look.

A Consumer Reports investigation in the US found high lead levels in some bubble tea products, echoing earlier concerns about cassava-based foods. The tapioca pearls, the drink’s signature “bubbles,” are made from cassava starch, which can absorb lead and other heavy metals from the soil as the plant grows.

Lead is naturally present in the Earth’s crust, and much of the world’s soil contains significant contamination. Many fruits and vegetables, including cassava, can absorb heavy metals during growth.

Consumer Reports tested tapioca pearls from popular bubble tea chains, Gong Cha and Kung Fu Tea, as well as packaged boba products from Trader Joe’s and WuFuYuan. Every sample contained some lead. Thankfully, none exceeded the levels that Consumer Reports considers concerning, and none had dangerous levels of arsenic, cadmium, or mercury in a single serving.

“These levels weren’t high enough for us to advise people to completely avoid bubble tea,” said James E. Rogers, PhD, director of food safety research and testing at Consumer Reports.

“However, this wasn’t a comprehensive survey of the boba and bubble tea market. The fact that three out of four samples contained more than half of our level of concern for lead in a single serving is a strong reminder that bubble tea should be enjoyed occasionally, rather than as an everyday drink.”

Beyond heavy metals, the starchy composition of tapioca pearls can pose other risks. Eating large amounts may slow stomach emptying, a condition called gastroparesis, or even cause blockages. Symptoms can include nausea, vomiting, and abdominal pain, and people with already slow digestion may be particularly affected.

Bubble tea can also impact kidney health. In 2023, Taiwanese doctors removed more than 300 kidney stones from a 20-year-old woman who reportedly drank bubble tea in place of water. Ingredients such as oxalate and high phosphate levels can contribute to stone formation, though this extreme case likely reflects unusually high consumption.

Jason Tsou, General Manager at WuFuYuan’s parent company, Shanghai ZhouShi Foodstuffs, said the company routinely tests its products for lead through an accredited laboratory. Following these recent findings, they have introduced stricter standards to ensure safety, as per New York Post.
