Why do Filipinos like eating rice so much?

Well, that has to do with the fact that the Filipino soil is ideal for rice cultivation. Also, given that rice is produced in abundance in the Phillipines, it becomes cheaper than other food staples. Therefore, rice easily became the most common dish in an ordinary Filipino household.
One can also say, that the neutral nature of rice flavour parries well with the Filipino traditional dishes like Adobo, Sinigang and Kare-Kare which are rich in flavour and welcome more neutral side dishes
