The RDA for protein is quite low, 0.8g per kg bodyweight, or about 10% of your caloric intake. You can meet this by eating just grains. However, as mentioned in the linked source, the RDA is intended to prevent nutrient deficiencies, not provide an optimal level of intake.

Rice does come up a bit short by my calculations, if you are just meeting your caloric intake needs. Oats provide more than enough, though.
