Aseem Malhotra, Science Director, Action on Sugar.
Young cardiologist, formerly of the Royal Free London, whose impassioned and articulate campaigning on the dangers of sugar has taken him to Downing Street and into TV studios – as his cross-over appeal sees him double up as a newspaper reviewer.

As science director of Action on Sugar, this media-savvy consultant is waging a war on the white stuff. He argues that too much attention has been on saturated fat, while the dangers of sugar have been under-stated. “I want to pressurise the Government to regulate the food industry to reduce the amount they’re spiking our food with,” he says. “Studies are now revealing excess sugar consumption increases the risk of heart disease and type 2 diabetes even in those of normal weight.”
