According to a team of researchers from Northwestern University, tea leaves and bags adsorb lead, trapping lead ions on their surfaces and filtering them from drinking water during the process of tea brewing.

That daily brew might be purifying the water, too. In a new study, Northwestern University researchers demonstrated that brewing tea naturally adsorbs heavy metals like lead and cadmium, effectively filtering dangerous contaminants out of drinks.

That comforting hot cup of tea—or refreshing glass of iced tea on a hot summer day—could help reduce the amount of toxic metals in drinking water, according to a new paper published in the journal ACS Food & Science Technology.

A new study from Northwestern University reveals that tea leaves naturally remove toxic heavy metals from water as they steep. The researchers found that lead and cadmium — dangerous contaminants that can pose serious health risks — cling to the surface of tea leaves, effectively reducing the levels of these metals in the final brew.

In the tea vs. coffee debate, some coffee fans hail the way coffee grounds trap heavy metals in water. Now, tea fans can clap back. Tea leaves, whether loose or in a bag, absorb heavy metals like lead and arsenic,

Scientists have good news for tea lovers. Brewing tea removes harmful heavy metals like lead and cadmium from the water, reports the journal "ACS Food Science & Technology". Researchers from Northwestern University in Evanston,
