Can Health Secretary Andrew Lansley change Britain's bad eating habits? Sheila Dillon hears how the debate is shaping up on the "responsibility deals" aimed at changing our diet.

With over 60 per cent of the British population now overweight or obese everyone agrees that change is needed in how we eat and what we eat. One part of the government's strategy involve so called responsibility deals, agreements with the food industry based around a series of pledges.

A growing number of food manufacturers and retailers have signed up, pledging to reduce calories, remove salt and harmful trans-fats from food. But will it deliver a big enough change in the nation's diet?

Sheila Dillon finds out how the Danish government has recently opted to place a tax on nutrients like saturated fat and sugar, meanwhile in New York City, mayor Michael Bloomberg has placed a ban on ingredients like trans-fats and is now placing restrictions on the size of soft drink portions.

So, to tax, ban or adopt voluntary agreements on food? Sheila hears how the three different ideas are being developed.
