Drinking tea lowers a woman’s risk of developing ovarian cancer, say researchers from the National Institute of Environmental Medicine, Karolinska Institutet, Sweden. You can read about this new study within the December 12/26 problem of Archives of Internal Medicine (JAMA).
According to background information within the write-up, few epidemiological studies have looked in the relationship specifically in between the consumption of tea and ovarian cancer – despite the fact that there has been evidence in the past indicating some rewards.
Lead researchers, Susanna C. Larsson, M.Sc., and Alicja Wolk, studied the association between tea drinking and ovarian cancer danger in 61, 057 females – all aged 40-76. All the ladies were part of a population based Mammography cohort (that had been carried out in Sweden).
The ladies had filled in a questionnaire which included 67 questions regarding their dietary habits among 1987-1990. 68% drank tea when a month or much more. The women had been followed up until 2004. During this period 301 girls developed invasive epithelial ovarian cancer.
The authors stated they observed that women who drank two cups of tea per day (or far more) had a 46% lower risk of ovarian cancer than non-tea drinkers. Each additional cup of tea per day was associated with an additional 18% lower threat.
Even the women who drank much less than 1 cup of tea per day had an 18% lower danger of developing ovarian cancer than the females who never drank tea. Those who had 1 cup each day had a 24% lower danger.
The writers also added that coffee consumption isn’t associated with ovarian cancer risk in this cohort.
