Now it's the green grocer's fault

A new study suggests the price of fresh fruits and vegetables has a stronger connection to weight gain among children than whether they live near fast-food outlets.

It adds more confusion to the muddy picture of what causes youngsters to gain weight.

Advocacy groups have suggested a strong link between obesity and the proximity of fast-food restaurants or the lack of supermarkets stocked with fresh food. But the new study by the Santa Monica-based Rand Corp. think tank found little support for that connection.
