Last month, Consumer Reports issued a report about boba. Sorry to say the results weren’t great. They tested boba from Gong Cha and Kung Fu Tea (both are huge chains) as well as packaged boba products including the Trader Joe’s boba kit and they found lead in EVERY sample. Although levels weren’t considered to be above their level of concern in one serving, we know that some people have a rather unhealthy several-times-a-week boba addiction and lead can accumulate. This heavy metal is typically found in the brain, liver, kidneys, bones, nervous system and reproductive systems so we should definitely not make boba a daily habit. Boba is made from tapioca which is derived from cassava root. It would be nice if the local boba shops who make their own housemade boba can test their tapioca flour (hint hint). And it’s not just boba! Remember tapioca is in a lot of products so be sure to check your ingredients for tapioca starch, syrup and flour in your processed foods and drinks.
BTW pictured is housemade boba with soft serve from in Milpitas. Delicious but lead level unknown!
