One change I like to do to muffins is to substitute regular baking flour with Red Fife Wheat. It is a different variety of wheat, and Canada's oldest. Here is a link to my dad's website (family farm) which he sells Red Fife.  http://www.ehnesorganic.com/faith-red-fife.html This is a great healthy alternative. I also like to add ground flax seed to my muffins for extra goodness! Just be careful how much you use as the muffins can become heavy.
