Water boiled in an aluminum kettle is drinkable, but long-term or excessive consumption is not recommended. Here's a detailed explanation:
Water boiled in an aluminum kettle is drinkable: Technically, water boiled in an aluminum kettle is safe to drink. While the chemical components in the water, such as aluminum, change after boiling, most values are generally still within the acceptable range according to health standards.
High aluminum content: Water boiled in an aluminum kettle produces a large amount of aluminum; the aluminum content after boiling can reach as high as 3.17 mg/L. Although aluminum is not officially listed in my country's drinking water hygiene standards, long-term or excessive aluminum intake is harmful to health, especially its effects on brain cells, which is widely recognized in the academic community.
Recommendation to use glass containers: To reduce the risk of excessive aluminum intake, it is recommended to use glass containers for boiling water. Water boiled in glass containers undergoes relatively less change in chemical components and is therefore safer.
Important Note: Although water boiled in an aluminum kettle is drinkable, long-term or excessive consumption is not recommended for health reasons. To reduce the risk of aluminum intake, it is best to choose containers made of other materials, such as glass, for boiling water.
