Research from Northwestern University suggests the health benefits of tea may relate to its ability to remove heavy metal ions, particularly lead, from drinking water. The study found that brewing black tea for five minutes can reduce lead ion concentrations significantly. Although the direct health ramifications of reduced metal exposure weren't explicitly tested, researchers propose that even small reductions in metal intake through tea could have positive effects on public health over time, potentially lowering risks linked to heavy metal consumption among populations.
The research from Northwestern University suggests that the health benefits of tea may stem from its ability to remove heavy metal ions from water, notably lead.
Benjamin Shindel, the first author, noted that tea brewing for five minutes significantly reduced lead ion concentration in water.
Though the health ramifications weren't tested, the researchers suggested that regular tea consumption could subtly reduce metal intake and associated health risks over the population.
The study indicated that tea not only provides flavor and comfort but also might play a role in diminishing exposure to harmful heavy metals in drinking water.
