I think it's a point well made. I think when we're considering advice about food for children, the foremost thing we are concerned about is that they have an adequate diet. To look at the implications of labelling, if it demonizes certain foods.... The foods we're particularly concerned with are dairy products. Where in the U.K. 60% of girls have low intakes of calcium, we want to be very cautious not to put girls off consuming dairy foods if they're labelled inappropriately.
We also are aware of processed foods that come out quite badly on the traffic light system. Things like breakfast cereals, because they are dry foods, end up being labelled as high in sugar or high in salt. But the amounts consumed are relatively small, about 30 grams, and the important thing is they're consumed with milk. So you need to look at them in the context in which they're consumed. You have to work out what contribution the food makes to nutrient intake in the diet versus the potential negative effects of the food.
In the case of something like cheese, it's very clear. Once you go above about 1 ounce--30 grams--a day, you're moving to an area where you're probably consuming too much. So it is about proportion.
