Elimination diets attempt to identity foods that cause certain symptoms or disorders. Here is a paper that focuses on elimination diets as interventions for, e.g., attention deficit hyperactivity disorder and autism spectrum disorder. Abstract:
Nutrition plays an important role in neurodevelopment. This insight has led to increasing research into the efficacy of nutrition-related interventions for treating neurodevelopmental disorders. This review discusses an elimination diet as a treatment for attention deficit hyperactivity disorder and autism spectrum disorder, with a focus on the efficacy of the food additives exclusion diet, gluten-free/casein-free diet and oligoantigenic diet. Furthermore, we discuss the potential mechanisms of elimination diets' effects in these neurodevelopmental disorders. The main candidate mechanism is the microbiome-gut-brain axis possibly involving complex interactions between multiple systems, including the metabolic, immune, endocrine, and neural system. We conclude with practical implications and future directions into the investigation of an elimination diet's efficacy in the treatment of attention deficit hyperactivity disorder and autism spectrum disorder.
Once again we see the power of nutrition and diet to affect serious human health and developmental problems, and we note the mention of "the microbiome-gut-brain axis" - demonstrating, also once again, the relevance of the gut microbiome to various aspects of human well-being.
