Extracts from Laudate Si.
227. One expression of this attitude (of heart) is when we stop and give thanks to God before and after meals.
I ask all believers to return to this beautiful and meaningful custom.
That moment of blessing, however brief, reminds us of our dependence on God for life;
it strengthens our feeling of gratitude for the gifts of creation;
it acknowledges those who by their labours provide us with these goods;
and it reaffirms our solidarity with those in greatest need.
Pope Francis.
