Stevia Prevents 96% of Skin Cancer in Mice: An extract of stevia prevented 96% of chemically induced skin tumors in mice after 20 weeks – and at a dose of just 1 mg per mouse! The extract was also found to be an extremely potent natural anti-inflammatory agent. The stevia extract contained mainly stevioside and rebaudiosides A and C, and was applied to the skin of each mouse. Perhaps sunscreen of the future will contain stevia! Until then, eating or drinking stevia-sweetened products may also have protective effects – and not just against skin cancer. Stevia has been shown to potently kill breast cancer cells as well as to lower blood sugar levels in diabetes in recent lab studies. Stevia has also been tested in clinical trials on blood sugar control in diabetes and for dental health, but not yet against cancer. Until then, it’s probably a better choice than aspartame, which a recent large study showed may increase the risk of leukemia, multiple myeloma and non-Hodgkin lymphoma in humans.
