Is There Too Much Aluminum in Tea?

The Nugget

  • Drinking moderate amounts of tea is unlikely to have harmful effects on humans due to the low bioavailability of aluminum in tea.

Make it stick

  • 🍵 Aluminum in tea is unlikely to be absorbed by the body due to it being bound to large phytonutrients.
  • 🍶 Drinking tea from dented cans can lead to higher aluminum levels due to leeching.
  • 🧒 Children with kidney failure should avoid excessive tea consumption due to potential issues with aluminum excretion.
  • 🌿 Natural unprocessed foods are a better choice to avoid aluminum exposure compared to processed foods.

Key insights

Aluminum Exposure in Tea

  • Aluminum, while abundant, may not be good for the brain, particularly in high exposure levels.
  • Aluminum can be found in various sources like drugs, processed foods, and even in small amounts in tea.
  • Tea plants can absorb aluminum from the soil, leading to its presence in tea.

Safety Recommendations for Aluminum Intake

  • The World Health Organization suggests a safe threshold of 2 milligrams of aluminum per healthy kilogram of body weight per week.
  • An individual weighing around 150 pounds shouldn't consume more than 20 milligrams of aluminum per day.
  • Beverages like tea may contribute up to about 4 milligrams of aluminum per day.

Bioavailability of Aluminum in Tea

  • While tea may contain aluminum, the bioavailability is low due to the strong binding of aluminum to large phytonutrients.
  • Studies show that the actual absorption of aluminum from tea is minimal, with possibly less than 10% being available for absorption.

Concerns for Specific Groups

  • Children with kidney failure may face challenges in efficiently excreting aluminum, making tea consumption less ideal for them.

Key quotes

  • "Drinking moderate amounts of tea is unlikely to have a harmful effect on humans due to the low bioavailability of aluminum in tea."
  • "Tea may not be a good beverage for children with kidney failure, as they can't efficiently get rid of aluminum."
  • "The bioavailability of aluminum in tea is low because it is strongly bound to large phytonutrients."
