The fast-food chain, reeling from last month's announcement of its first-ever quarterly loss, this week admitted it is "actively considering" the initiative, alongside healthy eating messages in its above-the-line advertising.
The decision would see nutritional information appear on packaging for all McDonald's products for the first time. It has already introduced a nutritional breakdown on its organic milk product.
It will form part of a comprehensive strategic business revamp that will include marketing campaigns and a rethink of the McDonald's menu.
Ad agency Leo Burnett has already been briefed to develop ad ideas focused on the brand, rather than product promotions.
This year will see the launch of a series of products, including low-fat items targeted specifically at more health-conscious consumers.
The initiative provides more nutritional information on product packaging will dovetail with the continuation of healthy eating and balanced diet messages that McDonald's says have been available in its UK restaurants since 1994. A McDonald's UK spokeswoman said: "We are always looking at new ways of communicating to our customers the responsible messages that we believe are important."
The chain has been stung by claims that its products fuel obesity, particularly among young people. Although a US lawsuit alleging this was recently rejected, McDonald's believes it can overcome growing antipathy by developing a more open relationship.
In the past year, McDonald's has come under fire for sponsorship deals with Unicef and children's TV programming strand Diggit. It is also facing competition from chains such as Subway, which is planning a major UK expansion.
