As a Certified Nutrition Consultant specializing in autism for over ten years, I have found the GAPS Diet to be one of the most effective strategies for aiding health and healing.
Extensive scientific research indicates that children with autism suffer from gastrointestinal disorders more than do neurotypical children ,. We also know that there is an increase in “leaky gut,” or gut permeability in autism ,, and that those with GI issues may not have enough carbohydrate-digesting enzymes (key rationale for to the GAPS diet) ,.
One study by Dr. James Adams demonstrated that ASD children had greater incidence of GI disorders and an imbalance of good bacteria; and that gastrointestinal symptoms correlate with autism severity .
It’s because of these underlying circumstances and observations that the GAPS Diet is so highly warranted as a dietary approach. The GAPS Diet is fundamentally helpful for gastrointestinal inflammation, dysbiosis, and digestive disorders.
The GAPS diet was created by Dr. Natasha Campbell-McBride and is based on the Specific Carbohydrate Diet (SCD). SCD was popularized by Elaine Gottschall who notably helped heal her daughter of ulcerative colitis through very strict dietary intervention; she brought SCD to the autism community.
The GAPS Diet calls for the avoidance of complex sugars and starches (that require carbohydrate-digesting enzymes)—and focuses on ingestion of monosaccharide carbohydrates (that do not require carbohydrate-digesting enzymes). Eating this way reduces undigested sugars and starches in the gut, things that most pathogenic microbes (like bad bacteria) feed on. This breaks the cycle of feeding pathogens and the inflammation and digestive disturbance they cause, and allows the body to receive nutrients from the carbohydrates it can better digest (monosaccharides). When you remove the substances causing a problem; you can reduce digestive discomfort, improve digestive capacity, and support healing of the gut – all of which can have positive affects on autism and neurological disorders.
However, it’s frustrating to hear/read comments like, “GAPS is the only diet that will heal the gut,” or “GAPS is all you need to do—you don’t need to worry about other things (i.e. salicylate, oxalates, etc.) if you’re doing GAPS.” This simply is not true.
GAPS is an outstanding diet. Dr. Campbell McBride synthesizes tremendous research and personal experience in bringing forward a useful strategy for so many people. However, it is not the only diet that heals. Just today, a client that followed GAPS for two years received some lab tests that helped explain her lack of results. Based on this new biochemical data, she wanted to switch to a new diet. But she was hesitant because she had heard that GAPS was the best healing diet. She asked me, “Have you ever seen a child heal on a diet other than GAPS?” My answer, “Absolutely.” Different diets are right for different people.
There is no “one-diet-fits-all.” Because of their biochemistry or health condition, I’ve found some people require a different diet, others benefit from employing additional dietary principles with a GAPS Diet. Following GAPS can set a foundation from which to include further diet and nutrition elements required for your specific health condition.
As a nutritionist that works with ALL specialized diets (not just the GAPS diet), I have a unique perspective into the varied dietary factors that influence physiological reactions and symptoms—clients (and doctors) seek me out specifically for my “knowledge base” and clinical experience in this area.
I work with low salicylate/phenol diets; including the Feingold diet and Failsafe diet, the Low Oxalate Diet, yeast diets, low FODMAPS (an acronym for various fermentable carbohydrates) diet, gluten-free and casein-free (GFCF), and grain-free diets from Paleo, to GAPS and SCD. I have years of experience helping identify food compounds that can cause reactions.
Salicylates can cause red cheeks and ears, hyperactivity, irritability, aggression, sleep challenges and more. Amines and glutamates can cause migraines, anxiety, pain, crying, hyperactivity and similar symptoms to salicylates. FODMAPS can cause digestive upset. Oxalates can disrupt cellular function, affect energy, and cause pain, inflammation and oxidative stress—if they get out of the gut and into the cell.
While improving the gut and subsequent biochemistry often improves tolerance of foods like high salicylates, it is sometimes essential to remove the salicylates to reduce the body burden and build up the sulfate pool. If you don’t consider this, the GAPS diet alone may not be sufficient to address phenol intolerance.
For most of us, avoiding extremely high oxalates is prudent. Spinach can have 700 mg of oxalate in one serving—10 times more in one serving than some people eat in a full day. This is enough oxalate to bind and inhibit mineral absorption (calcium and magnesium) in the whole meal. When the gut is leaky, oxalates are much more likely to get through and enter the bloodstream, especially when they are not bound to minerals. Once in the bloodstream, they can get inside the cell and create inflammation, oxidative stress and negatively impact mitochondrial function (conditions common in autism). Being cognizant of oxalate intake (like spinach) in the early stages of GAPS is important, and some people may need to be avoid high oxalate foods (like nuts) long term. Oxalates and these other food compounds should be considered on any healing diet.
I’ve also noticed a disturbing trend of people following a “low carbohydrate” GAPS diet. This concerns me. Problems can arise and one can get too low in carbohydrate, when people start cutting out more and more sugars than prudent. The GAPS is a specific carbohydrate diet not a low carbohydrate diet.
Take a fresh look at your GAPS diet…
Join us to learn more about what could be affecting your GAPS success, and discover ways to take your healing to the next level.
On Wednesday, March 13th, I will be leading a Nourishing Hope Support Club session on “The Gaps in GAPS.”
In this webinar I will share my experience with hundreds of clients/families so you can benefit from the knowledge – without having to make the same mistakes!
We will be discussing:
- What is the GAPS diet
- The science behind the GAPS diet and the biochemistry underlying autism
- The research on oxalates and phenols in autism and other disorders
- Common pitfalls and how to avoid them
- How to make the most of your GAPS diet
And I will answer your questions:
- How do I determine if phenols, oxalates, or FODMAPS are a problem for me or my child?
- Should I avoid fruit? Does it feed yeast on GAPS?
- Am I eating too many or too few carbs?
- Do I need to do this diet for life?
The Nourishing Hope Support Club is the only group of its kind; designed to support and bolster the success of those following specialized healing diets.
