Increasing taxes might not always be a very popular idea, but it might be a good strategy when it comes to encouraging healthy choices.
A tax on sugary beverages decreased sales of unhealthy sodas and other artificially-sweetened drinks, a new study, published in the Journal of the American Medical Association on Tuesday, found.

"We need policy changes that will help reduce sugary drink consumption," especially for children and teens, she said. Read more at CNN.
