Gut and Psychology Syndrome (GAPS)

What is GAPS?

gaps-logo-2GAPS stands for Gut and Psychology Syndrome. This means that many mental disorders such as Autism, ADD, ADHD, Depression, Anxiety, certain types of Epilepsy and Schizophrenia, are actually related to imbalances in the DIGESTIVE SYSTEM. By healing the Gut through a very specific diet, the brain is then able to recover, and in the majority of cases, these mental disorders can be stopped and / or reversed!

This concept was created by Dr. Natasha Campbell-McBride, a medical doctor practicing in the UK who has a son who was diagnosed with Autism. Researching what could help her son, Dr. Campbell-McBride found the work of an American pediatrician named Dr. Sidney Hass. Dr. Haas was able to completely cure Celiac Disease by putting his patients on a very Specific Carbohydrate Diet (SCD). This Specific Carbohydrate Diet was rediscovered by a woman, Elaine Gottschall who wrote a book called “Breaking the Vicious Cycle.” Mrs. Gottshall’s daughter suffered from Ulcerative Colitis and Epilepsy. After putting her daughter on the Specific Carbohydrate Diet, Mrs. Gottshall’s daughter’s seizures stopped, followed by the healing of her ulcerated colon.


Dr. Campbell-McBride slightly modified the Specific Carbohydrate Diet, and applied it to her son, who completely recovered from Autism. This remarkable personal success led Dr. Campbell-McBride to apply this diet to many of her patients with great success. As a result, Dr. Campbell-McBride created the concept of Gut and Psychology Syndrome or GAPS.

What Is The GAPS Diet?

There are two parts in the GAPS diets: the Introduction GAPS or the Full GAPS. The decision as to which one of the GAPS diets is best for an individual is decided according to each individual case. The GAPS diet is a very nourishing type of diet with the emphasis on animal proteins, healthy fats, and fermented food. The quality of the food has to be the best possible: fresh, organic, grass-fed, pastured or wild animals, homemade, from farmers, or from the garden. You are not hungry on the GAPS diet; on the contrary, your body is well fed and well nourished. You lose weight if you need to lose weight, but you gain weight if you need to gain weight because your metabolism is going to regulate itself.
