US food giant Kraft Foods has said it would take steps to cap portion sizes and provide more nutritional information in response to rising obesity rates.

Kraft, whose brands include Kraft cheese and Nabisco cookies, said its efforts would focus on four key areas: product nutrition, marketing practices, consumer information and public advocacy and dialogue.

To aid in this process, Kraft said it is forming a global council of advisors to help it structure its ongoing response to obesity and develop policies, standards, measures and timetables for implementation.

As part of the idea, the company plans to cap the portion size of single-serve packages and provide guidelines for the nutritional characteristics of all products.

The company said it would also try to improve existing products and provide alternative choices, where appropriate.

As regards its marketing practices, Kraft said it planned to eliminate all in-school marketing and initiate locally appropriate criteria to use with the vending industry in different regions of the world to determine the selection of Kraft products to be sold through in-school vending machines.
