Combine all the dry ingredients - the flours, soda, salt, oats and seeds in a mixing bowl and stir to mix around. Save a couple of tablespoons of rolled oats for the topping.
Pour in the honey and kefir and fold in until homogeneous. Pour into a loaf pan lined with baking paper and top with the extra rolled oats.
Bake in the preheated oven at 175°C (347°F) for 1 hour and 20 minutes, or until a toothpick inserted in the centre comes out clean. Take out of the loaf pan and let cool completely under a cloth before slicing.
