That's a good point, I cook my rice with all kinds of millet, barley, and seeds mixed in. My grandparents would probably think that's backwards, why would I eat barley when I could afford white rice.

But it's supposedly healthier (there's a famous story about how eating too much white rice crippled the Japanese navy [1]), and personally I think it tastes better too.
