Oat groats are even better that steel-cut oats. I cook them in a Tatung rice cooker (made in Taiwan) in the evening. Wash the like rice. Steam them inside the Tatung rice cooker. When cooked, let it cool and refrigerate it. In the morning, you now have more resistant starch from the chilled oat groats. About 60% is absorbed in your intestine, the remainder is not absorbed and passes into the colon, the insoluble fiber is now feeding the gut bacteria to produce short chain fatty acids. SCFAs boosts your immune system. I add wheat germs to my oat groats, Goji berries or other berries, nuts, and soymilk before I eat the oat groats. I put the oat groats with soy milk back into the Tatung steamer to steam and reheat the oats before eating it. I don't use the microwave to reheat. Temperature too high.
