Children also hear "When we eat this Bread and drink this cup, we proclaim..."
You and I know that our Lord also spoke of "Bread", and that to the properly catechized there's no scandal with respect to a potential contradiction of the Real Presence. But children -- and a great many others -- hear only "bread" and "cup". Moreover, to "proclaim" is not the point of the Eucharist. Its importance as an act of witness by the congregation is perhaps the least important thing about the Blessed Sacrament. To explain the point of the Eucharist as proclamation is to suggest that Eucharist is something commemoratiive and symbolic, done by the people and receiving its meaning and validity from us.
Even those who should know better can be affected subliminally by gratuitous imprecision in speech. It undermines a wholehearted appreciation of the Real Presence and muddies critical distinctions between Catholics and other Christian communions -- deliberately, some would say.
Before this, children (or the attentive ones, anyway) will hear the priest say "let Your Spirit come upon these gifts, so that they may become the Body and Blood ..." (or equivalent).

Interesting point.
