It is ingrained in our culture and in our psyche as Filipinos.
For as long as one can remember, Filipinos have been eating rice alongside favorite dishes and everyday meals. A pinoy can relate to feelings of fullness and satisfaction with eating rice. But it doesn't mean Pinoys can't live without all the carbs. We can adapt to other cuisines such as the case of Pinoys living abroad who have adapted to bread, cheese, couscous or other food staples.
Rice is our staple food. For a Filipino, its hard not to go without it.
