The claim that green tea can cure cancer is met with skepticism, but numerous studies suggest lifelong consumption may significantly reduce cancer risk. The ‘Asian paradox’ provides compelling evidence: despite high smoking rates in Asia, cancer rates remain lower than in Europe or America. Yale researchers attribute this to the high intake of green tea among Asians, often exceeding a liter daily.
Further supporting this, a study comparing elderly Japanese green tea drinkers with non-drinkers found that tea drinkers lived longer. Research at Murcia University in Spain discovered that EGCG, a green tea compound, shares similarities with the cancer drug methotrexate, potentially killing cancer cells in a similar manner. This is promising, as green tea could replace methotrexate, which has unpleasant side effects.
However, high quantities of green tea have been shown to cause cancer in lab rats, suggesting moderation is crucial, mirroring the effects of red wine. The research remains inconclusive due to limited funding from drug companies, leaving investigations to under-funded universities. More extensive research over the next few decades is needed to fully understand the health benefits of green tea.
