Preheat oven to 350F.
Combine flours, bran cereal, brown sugar, baking powder, baking soda, and nuts; mix well. Combine cranberries and granulated sugar. Stir sugared cranberries, egg, milk, orange juice, and margarine into flour mixture all at once, but only until mixed. Pour into greased 9x5x3" loaf pan.
Bake for 60-70 minutes, or until the bread is firm in the center. Cool in pan 10 minutes, remove to rack and cool on long side before slicing. Freezes well.
Note: 1/2 cup cranberry-orange relish can be substituted for sugared cranberries.
