Frequently Asked Questions

Where does the GAPS diet originate?

The GAPS diet is based on the Special Carbohydrate Diet (SCD). This diet was created by Sidney Valentine Haas, a renowned American paediatrician in the early 20th century. He developed the diet to treat coeliac disease after observing his patients' digestive conditions worsened following the ingestion of complex carbohydrates and starches. Several years later, a woman named Elaine Gottschall brought her daughter to Hass’s practice; she had ulcerative colitis and neurological issues, and the girl recovered within two years of following the diet. The SCD was then recognised not only for its benefits in treating digestive disorders but also for neurological conditions, including learning difficulties and autism. Dr Natasha Campbell used this diet in treating her own son, who had autism, and has since adapted the diet to form GAPS to address a broader range of diseases.

How long do I need to follow the GAPS diet?

The healing period is not short, as the nervous system is the slowest-healing organ in the body. Since all psychological GAPS disorders involve some degree of nervous system damage and dysfunction, it typically takes several years to regenerate the myelin sheath and establish new connections. Most GAPS disorders in adults require a commitment of two to three years to the new lifestyle changes, with additional time depending on the severity and duration of the condition.

Can I just follow the GAPS diet from the book?

Of course. This is how I began. I had consulted a GAPS nutritional therapist whose advice diverged from the diet, leading me to conclude I needed to learn to navigate the stages through my own trial and error. However, after reflecting on my experience, analysing GAPS patient testimonials, and adopting similar dietary interventions recommended by a neurobiologist, I now believe that following all the GAPS stages is unnecessary. As a result, I have simplified the diet by condensing it, making it easier to follow and reducing the risk of prolonging symptoms and exacerbating conditions.

Will I have to follow the GAPS diet for life?

You will never be able to eat a ‘normal’ diet, which means a typical Westernised diet rich in hyper-processed foods, baked goods, confectionery, and sugary drinks. These foods contributed to the disease process and will continue to harm the body and increase dysbiosis if consumed again. The inclusion of some whole foods, such as grains, is possible once more but will likely always be limited to fermented varieties in small amounts. The core diet staples will stay the same, but the quantities you need can be reduced depending on how much healing occurs.
