The bizarre eating disorder is thought to be a form of Pica, an illness which gives sufferers an appetite for substances without any nutritional value.Sporting a full set of normal-looking teeth, Mr Hunagundi blasts any suggestion he should curb the addiction.He said: ‘I have been eating bricks and rocks for around 20 years now. I love eating them. It has become a part of my life.

‘I started at the age of 10. Now it feels like a necessity to me. I can skip meals, but not bricks or mud.’I have suffered no side effects. My teeth are absolutely fine. I can bite into the hardest stone without a problem.’

His mother has spent 20 years trying to dissuade her son from eating away parts of their house and village.But Mr Hunagundi says the the building material tastes ‘A1’ – an Indian term for the best.Branding it better than ‘divine nectar’, he says it is best served with a glass of water.He said: ‘Other than bricks, mud and stones, I don’t like anything else. Even if you offer me divine nectar, I won’t take it.

‘My mother says don’t eat all this. She keeps insisting, but even if she gives me chicken fry, I don’t eat it. I don’t like that at all.’I need mud and bricks to eat. I can’t help my own habit.’
