Eating lots of white bread raises the risk of a cancer that kills thousands of Britons every year, according to new research.
Those who eat five slices a day are almost twice as likely to develop the most common form of kidney cancer compared to those who have one and a half slices.
Scientists put the cause down to refined cereals triggering a surge in blood sugar and insulin levels, which is thought to fuel cancer cell growth.
People should particularly cut down on white bread, which causes the biggest rise in blood glucose levels, and opt for wholemeal varieties instead.
The study also adds to the mounting evidence of the health benefits of following a low GI diet.
This involves avoiding processed and refined foods, such as white bread which have a high Glycaemic Index.
Whole grain foods are classed as having a low GI value as they lead to slower release of sugar into the blood stream.
The new study published in the International Journal of Cancer set out to investigate potential triggers of Renal Cell Carcinoma.
