ATLANTA (AP) - A new study shows small taxes on soda do little to reduce soft drink consumption or prevent childhood obesity.
The study is based on a 2004 health survey of children. It found that soda taxes, averaging about 4 cents on the dollar, didn't make much difference in consumption except among low-income children.
Even so, researchers believe larger taxes would make a difference. Currently, about 30 states have soda taxes.
