Assalaamu Alaykumsnip
Note how, before Allah (SWT) made the [non-Haraam] food of Ahl-ul-Kitaab (People of the Book), He (SWT) said: "This day". That means that it was one of the latest revelations of the Qur'an (the last revelation was: "This day I have perfected your religion for you").
ANYWAYS it doesn't matter. As is usually said on this forum by wise Muslim[ah]s, we should be focusing instead on improtant matters such as Tawheed and Al-Qur'an.
