Hard on the heels of a study that linked racism with breast cancer comes one which links the consumption of grapefruit by post menopausal women with this disease
From the BBC
Eating grapefruit every day could raise the risk of developing breast cancer by almost a third, US scientists say.
A study of 50,000 post-menopausal women found eating just a quarter of a grapefruit daily raised the risk by up to 30%.
The fruit is thought to boost levels of oestrogen - the hormone associated with a higher risk of the disease, the British Journal of Cancer reported.
But the researchers and other experts said more research was still needed.
A quarter of a grapefruit per day?
Disturbing since grapefruit are supposed to be good for you.
Interestingly enough the elevation of breast cancer rates in victims of racism is pretty much the same as the elevation in risk from consuming grapefruit.
From the racism study
In addition, the incidence rate ratio was 1.32 (95% confidence interval: 1.03, 1.70) for those who reported discrimination on the job and 1.48 (95% confidence interval: 1.01, 2.16) for those who reported discrimination in all three situations—housing, job, and police—relative to those who reported none
and the grapefruit study
Grapefruit intake was significantly associated with an increased risk of breast cancer (relative risk=1.30, 95% confidence interval 1.06-1.58) for subjects in the highest category of intake, that is, one-quarter grapefruit or more per day
That is they both only just manage to reach statistical significance at the 95% confidence interval.
So don't forgo grapefruit yet.
They are a very good source of vitamin C and anti-oxidants.
