Tunstall praises New York's health benefits

Scottish singer/songwriter KT Tunstall has praised New York City for its health benefits - and credits the Big Apple's sushi for aiding her recovery from a kidney problem.

The 'Suddenly I See' star insists snacking on the Japanese delicacy is boosting her wellbeing following a bout of kidney-related illness, as is a string of late night performances in the busy city.
