The GAPS Diet is a healing protocol based on the 100 year old, scientifically backed Specific Carbohydrate Diet, also called SCD.
It was first developed by Dr. Natasha Campbell-McBride MD based on her clinical experience with hundreds of patients and detailed in Gut and Psychology Syndrome (GAPS).
The GAPS book is an eye opening read about how the microbial environment within the gut can affect a person’s neurology and physiology.
This post discusses how to use the GAPS Diet to reverse conditions that are autoimmune in nature. Examples of GAPS conditions include allergies, eczema, psoriasis, ADD/ADHD, autism, celiac disease, asthma, Crohn’s disease, ulcerative colitis, IBS, obsessive-compulsive disorder, depression, anxiety, rheumatoid arthritis, lupus, fibromyalgia, diabetes, cancer, and the list goes on and on.
These conditions all can be traced to unfavorable conditions within the gut that cause undigested bits of food as well as pathogens and toxins to spill into the blood causing an unpredictable mix of autoimmune symptoms within the body.
That’s right – all autoimmune disease is rooted in the gut!
The GAPS diet as recommended by Dr. Natasha Campbell-McBride MD limits food intake to those items that can be fully digested even within a compromised gut environment thereby allowing the gut wall to heal. When the gut wall is allowed to finally heal by removing foods that cannot be fully digested, the holes in the gut wall reseal and the toxins that are causing autoimmune symptoms stop spilling into the blood and wreaking havoc in the body.
What Foods Do People on GAPS Diet Need to Avoid
At first read, the GAPS diet can seem quite complicated. In actuality, it is really very simple.
There are primarily two types of food molecules that folks in the process of healing their guts need to avoid:
- Disaccharides
- Starches (including resistant starch)
Disaccharides, or double sugars, are present in many carbohydrates including ALL grains. The compromised gut is unable to digest double sugar molecules because the lack of beneficial gut flora compromises the function of the enterocytes.
The enterocytes are the cells that reside on the villi of the gut wall and produce the enzyme disaccharidase which breaks down the disaccharide molecule into easily absorbed monosaccharide molecules. When the enterocytes are not nourished and strengthened properly by adequate beneficial flora, they become weak and diseased and may even turn cancerous. They do not perform their duties of digesting and absorbing food properly.
The critical importance of the enterocytes to health cannot be overstated!
Weak and diseased enterocytes also have trouble digesting starch molecules which are very large with hundreds of monosugars connected in long branchlike strands. People with weak digestion due to an imbalance of gut flora and messed up enterocytes have a terrible time digesting these complex molecules leaving large amounts of it undigested- the perfect food for pathogenic yeasts, bacteria, fungi and other pathogens to thrive upon.
Even the starch that manages to get digested results in molecules of maltose, which is – you guessed it – a disaccharide! This maltose also goes undigested due to a lack of the enzyme disaccharidase and becomes additional food for gut pathogens.
The GAPS Diet Bottom Line
Therefore, all foods containing disaccharide and starch molecules must be removed from the diet of a GAPS child or adult in order to allow the enterocytes to strengthen and heal the gut wall.
Dr. Campbell-McBride MD writes that clinical practice has shown that given enough time, the gut usually will again be able to digest these foods without any ill effects (aka, autoimmune disease) to the person consuming them.
The GAPS Diet is not a forever thing. It is a temporary measure to heal the gut wall and restrengthen the enterocytes so normal life can be regained without the burden of autoimmune disease. These GAPS recipes can make implementing the protocol much easier.
Foods To Eliminate
The GAPS child or adult must avoid all grains and any food that contains them. This includes wheat, einkorn, rye, rice, corn, oats, amaranth, kamut, spelt, triticale, barley, buckwheat, millet, teff, bulgur wheat, quinoa and any others.
In addition, Starchy vegetables like white and sweet potatoes, tapioca, cassava, parsnip, arrowroot and taro must be eliminated from the diet for a time.
Starchy beans and peas must also be avoided which includes pretty much all of them with the exception of green peas and navy beans.
All sugars including the lactose in milk and cream must be avoided. Raw honey, date sugar and syrup, and very ripe fruit would be the only sweets allowed. Fermented dairy like yogurt and kefir as well as butter and ghee are permitted unless the GAPS condition is severe.
How Long to Healing on GAPS?
Dr. Campbell-McBride says that, on average, it takes a child 6-18 months on the GAPS diet for the gut to heal. For an adult, it may take longer.
Note that it will not necessarily take this long for symptoms to subside, however. It is possible for symptoms to be substantially gone within weeks of eliminating these foods from the diet. Subsiding of symptoms does not mean the person is ready to consume grains and starches again, though.
Every person is different and the severity of his/her gut imbalance will determine how long it takes for the enterocytes to become strong again, the gut wall to heal and seal, and the ability to digest disaccharide and starch molecules regained.
Probiotics Alone Will Not Heal Your Gut
I’ve had folks say to me that they don’t need to go on the GAPS diet as they take a probiotic on a daily basis and eat probiotic rich, whole foods.
Please be aware that changing to even a completely unprocessed, whole foods diet and taking a daily probiotic will not necessarily heal your gut!
This approach alone will not heal your enterocytes and heal/seal the gut wall from years of abuse by antibiotics, the pill, other drugs, and processed foods.
The reason is that the enterocytes reside on the gut wall and the balance of flora on the gut wall cannot be changed. A probiotic supplement is not able to re-colonize this area of the gut!
Dr. Campbell-McBride MD writes that probably the only time that in our entire lives where we can populate the gut wall with beneficial bacteria is at birth.
Therefore, the only way to heal the enterocytes and the gut wall is to take away the food of the pathogens (disaccharides and starches) so that they weaken and the beneficial flora consumed by a probiotic can take hold and re-establish dominance in the rest of the gut.
Then, when these foods are re-introduced at a later time, the enterocytes will be strong and able to digest and handle them properly. This simply will not ever happen unless a period of time to heal these important little cells occurs.
Also note that even after healing, the gut will require constant infusion of probiotics on a daily basis. You can either supplement your diet with probiotic rich foods like yogurt, kefir, homemade saurkraut, kombucha and others or you can continue taking a therapeutic strength probiotic such as Bio-kult, which is recommended by Dr. Campbell-McBride.
GAPS Conclusions
One autoimmune disease begets another, so if you or someone you love has allergies or another mild form of autoimmune disorder, more severe autoimmune disease will very likely take hold in the future unless the root of the problem (gut imbalance) is addressed.
Autoimmune disease never gets better – it only gets worse over time.
Of course, severe autoimmune disease mandates the GAPS Diet as perhaps the only viable option for reversal and healing.
For this reason, it may be worthwhile to consider the GAPS diet as a measure to fix gut dysbiosis once and for all.

Sarah,
Do you know anyone who was actually healed of a peanut/tree nut allergy on GAPS? I can’t find any writing about this online–of actual cases–just people saying that it could happen. We started GAPS last November for my 2 year old who has those allergies plus eczema/asthma. The eczema and asthma are better now (eczema totally gone), but she recently had a severe reaction to pecans that opened my eyes to the severity of her allergy. We went to an allergist who confirmed the allergies and we are also working with a natural doc. Thanks for the info.
luis
I have scoured the internet for testimonials of people who have completely healed
from their ailments from this Gaps diet there are none ?? Even here, there are none.
I at least would hope to see someone’s testimonial of their eczema clearing up.
Laura
Do you think Gaps would heal Hashimoto’s Thyroiditis?
Isabelle
Can you point me to where this is discussed in the revised GAPS book? I cannot locate it.
Thanks

My 18 month old daughter has eczema and is allergic to cow dairy, eggs, and peanuts. I am wondering if we should try GAPS, but I worry that the lack of carbs will effect her brain development or weight. She is very tiny for her age (10th percentile) and can’t afford to lose any weight or have slowed growth. Any advice?
Thanks!
stefanie
I am wondering the same thing for my daughter. She is 3 years old now. She is allergic to dairy,eggs, nuts, soy,apple sauce, goat milk, and orange juice. If she has these foods she gets eczema. I wonder if GAPS would be a healthy diet for her? I think it would be difficult because she does love carbs and I know a certain amount of carbs are good for toddlers.
stefanie
btw she was also very low in weight (petite) she is 27 lbs now. Her sister at 9 months is 14 lbs and petite. We saw a gastrointologist and she said that the littlest one was healthy. But I am concerned because the littlest is allergic to goat and cow milk as well as coconut oil.I wonder why we have so many allergies? Do I have a compromised gut that is transferring it to my children? I am pregnant now with the third and I hope he doesn’t have allergies. ALso they were all c-secs.
Sarah
Izzy, please check out some of the other diet protocols, such as low FODMAP out of Australia or the RPAH/Failsafe diet out of Britain. I enjoy this blog and have been learning about GAPS for my own health (I am nursing so have to wait a while b/c of detox). However, my daughter has some severe gut issues and was prescribed low FODMAP by our city’s best children’s hospital pediatric GI. Although very allopathic in his approach, he believes very strongly in the efficacy of dietary interventions. You will definitely find some similarities among all of these protocols, but GAPS does not work well for some of the sensitivities that these other protocols specifically address…worth looking into so that you can perhaps combine them or do one protocol first and then another.
Izzy
Any suggestions for people who have sensitivities to nuts and meats and grains? Lots of allergies. We tried GAPS on our 3 yr old and didn’t see much improvement. She lost weight, tried it for 8 months. No growth, her nails stopped growing, she did horrible. There was hardly anything she can eat. I am sure she has leaky gut and need help for that desperately. She is currently paleo, doing better but still suffering from a lot of the behavioral and skin and gastrointestinal symptoms. Please help. We’ve been consulting w/ someone who’s supposed to be an expert on GAPS and traditional diets(in CA) and we’re not getting much help.
Onika
I read disaccharides compose 7% of honey. Is it ok to eat honey because it is such a small amount?
Tara
Hi Sarah,
Would like to know to if the GAPS diet can heal a person suffering from multiple sclerosis.
Raquel
I would love to try GAPS. I have multiple food allergies that cause me to get acne and itchy spots on my face and neck. I didn’t develop any of these allergies until around the same time that I went through puberty. I grew up eating mostly fast food, was on lots of antibiotics and was put on the pill for my acne and heavy periods at around age 13! I also took accutane which now I know did huge amonts of damage, no thanks to the stupid dermatologist who told me that there was NO connection between food and acne! I already started eliminating grains and I feel much better, I have more energy and I’m not constipated anymore. Has this diet helped anyone to get rid of their dairy allergies?
