Researchers from Emory University in Atlanta have said that following the Paleo or caveman diet can cut the risk of bowel cancer by a half, with men particularly benefiting from the popular diet.

The researchers studied the dietary habits of more than 2,000 women and men who were between 30 and 74, and ranked how 'Paleolithic' their diet was, as well as being examined for the consumption of a 'Mediterranean' diet.

The risk of developing a colorectal adenoma (benign tumour) was cut by 29 per cent for women who followed the Paleo diet, and by 26 per cent for those who were eating a Mediterranean diet.

Men came out on top, with a drop of 51 and 42% respectively.The findings were published in the American Journal of Epidemiology.

Experts have long claimed the benefits of eating like a 'caveman', and this new study seems to back up the theory.The Paleo diet became popular following the publication of The Paleo Diet by American nutritionist Loren Cordain back in 2010.

The diet is now popular with many celebrities, including Jack Osbourne who turned Paleo after being diagnosed with multiple sclerosis, Uma Thurman, Megan Fox and Matthew McConaughey.
