Now, this is my own personal crusade (after some major GI problems), but I think in general we eat too much wheat - which is easy to do since it is in so many prepared foods.
I can't really point you to any particular book. The idea of reducing/eliminating wheat consumption (particularly the way it is prepared in the U.S.) comes up in various places. Breaking the Vicious Cycle by Elaine Gottschall is addressed to people with more extreme conditions like colitis, diverticulosis, etc., but it has an interesting take on the impact of starches and sugars on the digestive track.
So often on health-related boards, people will have similar complaints to yours - especially the low energy - and they say they are eating a very healthy diet, will post a sample menu for the day, and wheat shows up prominently in at least two meals.
Best wishes! |
