PepsiCo is to promote the benefits of its healthier foods and drinks with a new uniform labelling on its brands in the US.

The company will introduce a green dot onto the packaging of healthier brands such as Diet Pepsi and Tropicana juices with the words "Smart Choices Made Easy" on the packaging. The package will also include a line explaining the products' specific benefits.

It is expected that PepsiCo will begin rolling out the new labelling in September. All its healthy products should include the green dot by the end of the year.

PepsiCo chairman and CEO Steve Reinemund said: "We are very serious about this effort. This isn't something we started on yesterday, and this isn't something we are going to walk away from tomorrow."

Pepsi said it has examined levels of fat, sodium and sugar as well as fibre vitamins and nutrients in order to decide which products to label in this way.
