The Centre for Science in the Public Interest (CSPI) says using toys to promote its Happy Meals is ‘unfair, deceptive and illegal’, under American State laws.

McDonald’s insists that it uses toys and popular characters to promote healthy options such as fruit, carrot sticks and organic milk.

However, the CSPI says the reality is that 93% of children who have a Happy Meal walk out with a portion of fries alongside products like burgers and chicken nuggets.
