The Consumer Advice Centre in North Rhine-Westphalia, Germany, has advised consumers to carefully review the ingredients and preparation guidelines on matcha tea packaging before purchase. Matcha, a traditional Japanese green tea, may carry certain health risks due to environmental factors affecting its growth.
Aluminium and Lead Concerns
According to the German centre, matcha tea can absorb aluminium from the soil in which it grows, which, when consumed in large quantities, may have long-term effects on the nervous system and bones. Additionally, matcha may contain lead, which can harm the kidneys, heart, and blood vessels.
Recommended Dosage
Experts recommend limiting matcha tea consumption to no more than three cups daily, using no more than one gram of matcha powder per cup.
Rotating brands periodically can also help reduce the risk of exposure to harmful substances. Furthermore, matcha tea is not recommended for children due to its high caffeine content.
