Having rice or bread?

I think Japanese should eat rice in the morning, because we live on rice. Most of people in Japan eat bread in the morning. I like bread because there are a lot of types of bread; for example, sweet roll, croissant, sandwich and so on. They are very delicious, but I can't be full. When I had bread for breakfast, I usually say "I'm hungry." before lunch. However, if I have rice for breakfast, I don't feel "I'm hungry.", so I want to eat rice for breakfast.
