Reduce Skin Cancer Risk with Black Tea

Black tea is made from the dried leaves of the Camellia evergreen shrub that is native to southeast Asia. Green tea and oolong tea also come from this plant. In 2007, Partmouth Medical School did a study and found that drinking at least two cups per day of black tea can cut the risk of skin cancer in half.

The tea has polyphenols that could protect the body against UV radiation. Tea has an antioxidant called catechins that can inhibit the growth of cancer cells. Both black tea and green tea has 10 times the amount of antioxidants found in fruits and vegetables. The antioxidants have a detoxifying effect that protects cells from free radicals. Free radicals can cause damage to cells that can cause blood clot formation, atherosclerosis, and cancer. Studies have shown that when tea extracts are applied to the skin, the risk of skin cancer due to sun damage is decreased.

Increase Metabolism with Tea

There are catechins and thermogenic properties in green and oolong teas that can increase metabolism and speed up fat oxidation. One cup of green tea can increase metabolism by 4 percent for 1 and 1/2 hours. One cup of oolong tea can increase metabolism by 10 percent for 1 and 1/2 hours.

Green tea is also an antioxidant that is rich in compounds called polyphenols that reduce the growth of new blood vessels that feed tumors. It is also a good detoxifier that activates enzymes in the liver that eliminate toxins from the body. It has even been shown to increase the effect of radiation on cancer cells to help cancer patients. It prevents the formation of free radicals that can cause diseases, such as cancer, stroke, and heart disease.
