There is no official "top 10 carcinogenic teas" list. However, certain tea - related situations may pose a cancer - related risk:
- Mold - contaminated tea: If tea is stored improperly and becomes moldy, especially when contaminated by Aspergillus flavus, it may produce aflatoxin, a strong carcinogen. Long - term consumption of such moldy tea can significantly increase the risk of liver cancer.
- Tea with excessive pesticide residues: When tea is grown, if too many pesticides are used and not properly decomposed or washed away during processing, the residual pesticides in the tea may be harmful to human health. Some pesticides have potential carcinogenic effects, and long - term consumption of tea with high pesticide residues may increase the risk of cancer.
- Tea with heavy metal contamination: Tea plants may absorb heavy metals such as lead and cadmium from the soil or environment during growth. If the content of heavy metals in the tea exceeds the standard, long - term consumption may damage human organs and increase the risk of cancer.
- Over - heated tea: Although not a type of tea itself, drinking tea at a temperature above 65°C for a long time can scald the oral cavity, esophagus and other mucous membranes. Repeated damage and repair of the mucous membranes may increase the risk of esophageal cancer.
In general, to reduce potential health risks, it is recommended to choose tea from regular channels, store tea properly to avoid mildew, and pay attention to the temperature when drinking tea.
