An Indian man who claims he is addicted to sand consumes an entire plate of gravel every day. <br /> <br />Hans Raj, 45, has shunned normal snacks and instead chews on pieces of brick and rock, which he says provide him with energy and minerals. <br /> <br />He first developed a penchant for eating grit when he was 20, and has become known as 'the sand man' in his home state of Uttar Pradesh due to his bizarre habit. <br /> <br />Doctors say he may be suffering from Pica, an impulsive and untreatable eating disorder which sees sufferers develop appetites for non-edible foods with no nutritional value
