You sometimes read that "Rice (wheat, potatoes, millet) is the staple of diet in ...". The phrase doesn't hit home until you see it in action. Each student ate this much rice for lunch and again for dinner. If they were hungry, had worked hard, or it was a festival, twice as much. Your ancestors may have done the same with potatoes, if they were German or Irish. When Jesus told people to pray "Give us this day our daily bread", He was talking about a loaf this big that everyone ate every day, not a roll on a small plate to the side of the chicken and peas. Note it isn't quite all rice; we got sacks of bulgar wheat for free from the US of A, via Public law 480, which the cooks mixed in with the rice, at about two parts rice to one part wheat.
