After reading Jane Gottachall's book and website and following diet strictly, I realize error of my ways. All those starches (even 'healthy' ones) sweet potatoes, rice, quinoa were beyond my ability to digest and the undigested starches were feeding the bad bacteria and yeast. Geez all those food journal entries when I would go down after eating linked to the complex carbohydrates my gut was not able to eat. Makes sense since they require more steps to break down as opposed to simple foods that digest easy in one step. JAne is brilliant. Her life dedicated to studying the science behind digestive disease is awe-inspiring. Worth a read is her book. Changed my life
