Lower Incidence of Kidney Cancer Among Women Who Eat Fruits &

Women keen on bananas, salads and root vegetables may be
less likely develop kidney cancer, suggests a new Swedish
study.
Researchers at the Karolinska Institutet in Sweden
analysed dietary information from 61,000 women aged 40-76
and followed the group for 13 years. They found that
those who consumed five or more servings of fruit and
vegetables daily reduced their relative risk of
developing renal cell carcinoma - the most common form of
kidney cancer - although these results were not
statistically significant.
However certain fruits and vegetables - namely bananas,
root vegetables, white cabbage and salad veg - appeared
to offer strong protection, report the authors in the 20
January issue of the International Journal of Cancer (vol
113, issue 3, pp451-5).
Eating salads more than once a day decreased the risk by
40 per cent in comparison to no consumption, while women
who ate bananas four to six times a week had about half
the risk of kidney cancer as those who did not eat the
fruit.
Bananas are rich in potassium, the anti-carcinogenic
potential of which has been speculated upon by
epidemiologists.
Regular consumption of root vegetables like carrots was
linked to a 50- 65 per cent decrease in risk.
The number of people being diagnosed with kidney cancer
has increased sharply over the past 20 years. Almost
6,000 people in the UK are told they have the disease
each year.
However, rates are much higher in western countries than
they are in developing countries leading scientists to
suspect that lifestyle factors, such as smoking and
obesity, play an important role.
There is some previous evidence to show that regularly
eating fruit and vegetables may protect against kidney
cancer but the data has not been consistent.
The new study is the largest to show an association
between kidney cancer and fruit and vegetable intake,
according to lead author Dr Bahram Rashidkhani.
The study follows a major review of evidence to date on
fruit and vegetable consumption and breast cancer risk,
finding that it is insufficient to support any protective
effect.
