How to get people to buy healthier food: cardboard cutouts?

Can it really be this easy?  Morrison’s, a grocery chain in the U.K., put cardboard cutouts of doctors near the produce section.

A new pilot scheme in a Morrisons store in Salford, using cardboard cut-outs of local GPs in the fresh produce aisles delivered a 20% rise in the sales of fresh fruit and a 30% uplift for frozen fruit.

All of this is part of Great Britain’s Public Health “Responsibility Deal,” which aims to enlist businesses to voluntarily promote health objectives.

The Responsibility Deal embodies the Government’s ambition for a more collaborative approach to tackling the challenges caused by our lifestyle choices.

Organisations signing up to the Responsibility Deal commit to taking action voluntarily to improve public health through their responsibilities as employers, as well as through their commercial actions and their community activities. Organisations can sign up to be either national partners or local partners.

The principles and ambitions of the Responsibility Deal are set out in its core commitments and supporting pledges.

This is all it takes?  Really?

Why do I think this won’t work nearly as well in America?  We have a long way to go, says the USDA.

What might work?  Celebrities?  Sports figures?  Political figures?
