Eating three eggs per week increases risk of prostrate cancer in men
Experts in the U.S. claimed that men who consume more than two and a half on a weekly basis were up to 81 per cent more likely to be killed by the disease.
They suggested the damage may be done by the large amounts of cholesterol or choline – a nutrient that help cells to function properly – that are found in eggs.
Hidden risks: Men who eat more than two-an-a-half eggs a week are 80 per cent more likely to get prostate cancer, a study shows.
The average Briton consumes an estimated 182 eggs a year – roughly three and a half per week.
Until recently, the British Heart Foundation recommended eating no more than three a week because of fears that they raised the risk of heart attacks and strokes.
It dropped the recommendation in 2007 after evidence emerged that very little of the cholesterol contained in eggs enters the bloodstream.
The latest study, conducted at the Harvard School of Public Health in Boston, investigated the role of eggs in prostate cancer following the discovery last year that men diagnosed with low-grade tumours appeared to be more likely to be killed by them if they had an egg-rich diet.
Health problems: Prostate cancer cells could be affected by high level of cholesterol in eggs.
The team examined the eating habits of 27,000 men over a 14-year period.
They found no significant links between the amount of meat eaten and tumours – but a higher number of cancer deaths were evident among those who admitted consuming lots of eggs.
In a report on their findings, the researchers revealed: ‘Men who consumed 2.5 eggs or more a week had an 81 per cent increased risk of lethal prostate cancer compared to men who consumed less than half an egg a week
'Although additional studies are needed, caution in egg intake may be warranted for adult men.’
However, Sarah Williams, health information officer at the charity Cancer Research UK, said: ‘There is a small amount of previous research on the link between eating eggs and the risk of developing and dying from prostate cancer, but the results have been contradictory and it’s still not clear whether there is a real effect.
