Green Tea: Drink a lot of it!
There are so many papers in leading medical journals on the positive effects of drinking green tea that I haven’t had time to read them all. It’s good for preventing heart disease, ulcers, losing weight, you name it. There are dozens of papers on green tea effects on cancer and here is one of the best, because it begins to show the dose response curve, and compares Japanese (a relatively uniform population who all drink green tea) drinking under three cups a dose to those who drink over ten cups a day. The high dose eliminates almost 50% of all cancers and slows down the growth of remaining cancers. Need I say more!
Preventive effects of drinking green tea on cancer and cardiovascular disease: epidemiological evidence for multiple targeting prevention
Nakachi K, Matsuyama S, Miyake S, Suganuma M, Imai K.
The significance of drinking green tea in prevention of two of the main lifestyle-related diseases, cancer and cardiovascular disease, was demonstrated in terms of a prospective cohort study on a total of 8,552 general residents in Saitama Prefecture, Japan. On the basis of the follow-up study, we revealed decreased relative risk of cancer incidence for those consuming over 10 cups a day, compared with those consuming below 3 cups: 0.54 (95% confidence interval, 0.22-1.34) for men, 0.57 (0.34-0.98) for women, and 0.59 (0.35-0.98) for both sexes. Furthermore, a significant delay in cancer onset was associated with increased consumption of green tea. Next, decreased relative risk of death from cardiovascular disease was 0.58 (0.34-0.99) for men, 0.82 (0.49-1.38) for women, and 0.72 (0.60-1.04) for members of both sexes consuming over 10 cups a day. Finally, we evaluated the life-prolonging effects of drinking green tea on cumulative survival, using the life table.
