Rice and Whole Grains for Rice Cooker

"My family eats a lot of white rice as a staple. For years I've wished to work a few whole grains in the mix to increase the nutritional value, but didn't know how to manage the different cooking times in the rice cooker. I recently figured it out. Right now I'm using 1 part whole grains to 3 parts white rice. It tastes good and they're eating it! Maybe later I'll try increasing the proportion of whole grains--as long as the family still likes it. I've used millet, grits, brown rice, and buckwheat. I'm also thinking of trying red and purple and black and wild rice, barley, whole oats, buckwheat groats, coarse cornmeal, and quinoa. Maybe also sesame and sunflower seeds. At high altitude, lentils, split peas and black-eyed peas don't cook tender enough, but with a pressure rice cooker, or at low altitude, I think they might work. If anyone experiments and learns anything, let me know. This method yields a moister rice like the Chinese prefer, not chewy rice with distinct grains."
