The findings of the study support the possibility that green tea ingredients are capable of slowing down the growth of cancer
-causing viruses and micro-organisms.
41,761 Japanese adults studied
To determine the association between green tea intake and risk of blood cancer, researchers from the Tohoku University Graduate School of Medicine in Sendai, Japan, analyzed the data collected from 41,761 Japanese adults including 19,749 men and 22,012 women, aged 40 to 79.
All these subjects had no previous history of health complications like cancer.
The researchers collected information on the diets and green tea drinking habits of the subjects. To get a fair idea about the lifestyle of the subjects, they also considered factors like age, gender, education, smoking status and history, alcohol use, psychological distress etc.
Subjects consuming 5 cups of green tea less likely to develop cancer
A review of the medical condition of the participants suggested that those who consumed five cups of green tea regularly had 42 percent lower chances of developing all types of blood cancer than those who drank one or fewer cups of the green tea.
Similar intake of green tea was also linked with reducing the risk of lymphoid system cancers--associated with digestive system--by 48 percent.
The findings of the study reported in the September issue of American Journal of Clinical Nutrition also suggested that green tea cut down the risk of cancer among obese study subjects.
Experts say that obese people are at a higher risk of developing such complications.
Previous studies also suggest that green tea promises varied health benefits including prevention of cardiovascular events, lowering the levels of 'bad' cholesterol, boosting the brain activity and improving overall health.
However, researchers of the current study maintain that further research is required to explore whether regular consumption of green tea could help lower the risk of other cancers as well.
