Help prevent multiple cancersChinnapong/Shutterstock
Research on the benefits of green tea and cancer prevention is still in early stages, but the results are promising. Researchers suspect that polyphenols in green tea help kill cancer cells and stop their progression, an important role to prevent various cancers.
• In a study of 472 women with breast cancer, those who drank the most green tea experienced the least spread of the disease. Researchers also found that women in the early stages of breast cancer who drank at least five cups of green tea every day during their diagnoses were less likely to have the disease recur after the completed treatment.
• In looking at more than 35,000 women in the Iowa Women’s Health study, those who drank two or more cups of tea a day were almost 30 percent less likely to develop colon cancer than those who rarely drank tea.
• One Chinese study found that men who drank more than three cups of tea a day reduced their risk of prostate cancer by 70 percent. In another study funded by the National Institute of Health, 79 men with prostate cancer were told to either drink 6 cups of green tea a day or 6 cups of water. After 3 to 8 weeks, the levels of prostate-specific antigen, a protein that may indicate cancer, were lower in the men who drank green tea than those who drank water. An indicator of inflammation, nuclear factor-kappaB, linked to cancer growth, was also lower in the men who drank the green tea.
• In skin cancer studies, lab animals that were given green tea developed 1/10th as many tumors as animals that were given water. The EGCC in green tea inhibits the production of urokinase, an enzyme that cancer cells need in order to grow. It also seems to stimulate the process of programmed cell death, or apoptosis, in cancer cells. Pair your green tea with these 30 foods that help prevent cancer.
Make your heart healthierAndrei_R/Shutterstock
Green tea contains significant amounts of flavonoids, antioxidants that protect against heart disease by slowing the breakdown of LDL cholesterol, preventing blood clots, and improving blood vessel function. The benefits of green tea also include associations with lower cholesterol and lower rates of artery blockages. People who drink a cup or two a day have a 46 percent lower risk of developing narrowed arteries. Upping that to three cups a day lowers the risk of having a heart attack by 43 percent and of dying from a heart attack by 70 percent. It can even help prevent a second heart attack. In a study of 1,900 patients recovering from heart attacks at Beth Israel Deaconess Medical Center in Boston, the death rate among patients who drank at least two cups of tea a day was 44 percent lower than among non-tea drinkers.
