Having eggs for breakfast might seem like a reasonably healthy choice but eating just three a week can significantly increase a man's chance of getting prostate cancer, a study has shown.Men who eat more than two-an-a-half eggs on a weekly basis are 80 per cent more likely to contract the disease, claim researchers at Harvard School of Public Health in Boston.The risk from eggs could be due to their high levels of cholesterol and choline, a nutrient that helps cells function, according to the scientists.But cancer groups said the link between eggs and prostate cancer could be down to other factors, as men who ate the most eggs were also more likely to have a poor diet, be overweight, smoke and take less exercise.British people eat an average of 182 eggs a year, and around 31million eggs are bought every single day.The British Heart Foundation used to recommend no more than three eggs a week because of fears it might increase the risk of heart attacks and strokes.But it dropped the recommendation in 2007 when new evidence showed that, although eggs contain cholesterol, little is deposited in the bloodstream.
