Is Bubble Tea Bad for You? New Research Raises Concerns

Topic: Health

A popular drink may contain high levels of lead and sugar. Tapioca pearls can cause digestive problems and kidney stones. Regular consumption is linked to health issues like obesity, diabetes, and mental health concerns.

Bubble tea has become a favorite among many, but new research suggests it may not be as harmless as we thought. Consumer Reports found high levels of lead in some bubble tea products sold in the US. This is concerning because tapioca pearls are made from cassava starch, which can absorb heavy metals like lead from the soil.

Eating large amounts of tapioca pearls can also slow down digestion and even cause blockages. People with sluggish digestion may experience more severe symptoms like nausea, vomiting, and abdominal pain.

Bubble tea may also affect kidney health. In 2023, doctors in Taiwan removed over 300 kidney stones from a 20-year-old woman who had been drinking bubble tea instead of water. Some ingredients in the drink can promote kidney stone formation.

The drink's high sugar content is another concern. A typical serving contains between 20-50g of sugar, which is similar to or even exceeds the amount found in a can of Coca-Cola. Regular consumption has been linked to health issues like obesity, diabetes, and metabolic disease.

Surprisingly, bubble tea may also be linked to mental health concerns. Studies have found higher rates of anxiety and depression among children who frequently drink bubble tea.

Doctors have even observed tapioca pearls showing up on medical scans of patients hospitalized for unrelated reasons.
