Listen to Angela's interview with Lucas Seipp-Williams, describing her experiences with the GAPS diet.

BrainFood_Interview_GAPS_Autism_Diet.mp3 (23 minute mp3 file)
The recipes in The Brainfood Cookbook are based upon the Specific Carbohydrate Diet (SCD) and Gut and Psychology Syndrome diet (GAPS).
Elaine Gottschall researched/created the Specific Carbohydrate Diet (SCD) for her daughter’s Ulcerative Colitis. (see: Breaking the Vicious Cycle) Later, Dr. Natasha Campbell-McBride took the SCD a step further by
researching and creating the Gut and Psychology Syndrome diet (GAPS) for her child’s Autism. (see: Gut and Psychology Syndrome)
Listed here is a general overview (with many of my opinions noted) of legal/illegal foods on the GAPS diet. (GAPS is slightly stricter than the SCD)
