Tories and Labour urged to show ‘courage’ to act on unhealthy food

Exclusive: King's Fund issues challenge as poll finds two-thirds of people want firms to be forced to cut sugar, salt and fat

Britain's political parties have been urged to show courage by forcing food producers to make their products healthier, as new polling shows two-thirds of voters back the move.

Compelling food manufacturers to strip out large amounts of fat, salt and sugar would help denormalise" the routine consumption of unhealthy food, Sarah Woolnough, the chief executive of the King's Fund, told the Guardian.
