Green Tea Cancer &
More Evidence on Green Tea
A new study by a team of
Swedish researchers adds support to the growing body of evidence that
green tea contains compounds that fight cancer. Drs. Yihai Cao and Renhai
Cao of the Karolinska Institute in Stockholm found green tea contains a
compound called epigallocatechin-3-gallate (EGCG), which helps
inhibit blood vessel growth. This could be useful in preventing
tumors from forming new blood vessels, which they need to survive. In a
study on mice, the researchers also found animals fed green tea showed a
55-percent to 70-percent reduction in blood vessel development in the
cornea of the eye, a finding that could prove helpful to diabetics
suffering from retinopathy, researchers say.
Other studies have shown EGCG
blocked an enzyme needed for cancer cell growth and kept cells from
becoming cancerous without harming surrounding healthy cells. The
researchers point out heavy consumption of green tea may not be beneficial
for women who are pregnant or for people recovering from wounds,
conditions that both require blood vessel development.
Green Tea Battles Arthritis
Antioxidants found in green tea
may reduce the severity and even prevent symptoms of rheumatoid arthritis,
a new study suggests. The antioxidants, called polyphenols, appear to
more antioxidant potency than some vitamins. Researchers also point out
there is anecdotal evidence suggesting that people living in India, China
and Japan -- where green tea consumption is high -- have lower rates of
