For people that tolerate it, GAPS allows lactose-free dairy (homemade yogurt or kefir fermented at least 24 hours, certain cheeses, etc). At the beginning of GAPS, however, one also removes casein (milk’s protein). This is because for most people with a compromised gut, casein is also too difficult to process.
We have received varying instructions regarding the introduction of dairy. Below is my current understanding of the GAPS approach.
Doing the Intro?
If one is doing the intro progression, healing is more quickly established than otherwise, thus dairy can be added earlier. In this case, one would start using ghee from Stage 3 of the intro. After six weeks of no other dairy, she would try a teaspoon of GAPS whey, yogurt or kefir, and slowly and methodically work up from there (and on to other GAPS-friendly dairy products) at her own pace.
Update: Dr Natasha now supports the use of whey, yogurt, etc, in intro for people struggling with chronic and persistent diarrhea or constipation. While I personally still like to see dairy out for at least six weeks before its reintroduction, if one wishes to test in their body Dr Natasha’s new position for dairy’s inclusion in early intro, my recommendation is to keep dairy out for at least two weeks, preferably starting Day 1 of intro, before reintroducing any form of it. (Two weeks is a standard period of elimination for intolerance/allergy testing.) While this elimination period can be done any time, again for most people it is most effective done starting with Day 1 of intro.
Skipping the Intro?
If one is skipping the introductory progression, the body will require much more time to heal. In this case, one eliminates all dairy (except ghee) for six months then tries GAPS yogurt or kefir (starting with a teaspoon or less), and some months later, butter, and six months later again, lactose-free cheeses.
Why does the intro mention yogurt and kefir?
Some people methodically tested their dairy reaction pre-intro. That is, they eliminated it for at least six weeks, reintroduced it properly and noted no problems. These people are able to use yogurt or kefir in the intro. Most of us did not properly test dairy previous to intro and thus cannot use it until later.
Best Dairy
Clean raw dairy, full of enzymes, is more easily tolerated, and more health-giving than pasteurized. Pasteurized will do, though.
Dairy that is free of pesticides and antibiotics (organic) can also make all the difference to one’s tolerance.
Goat milk (whether raw or pasteurized) is more easily tolerated by many, especially children with autistic traits. The casein in goat milk seems to be more easily assimilated by the body than the casein in cow’s milk is. If possible, try products made from goat’s milk first.
All dairy must be pure: No extra ingredients, thickeners, etc. (Salt in butter is okay, but unsalted is preferable.)

I had my gall bladder out and am now on gaps.
What grains are first to introduce? How does that relate to dairy intro’s?
Hi
I purchased NCM’s most recent books. I didnt read in that edition that there should be a 6 week abstaining from dairy to test for sensitivity to dairy.
Did I misunderstand it? It seems to say just put the dairy on your inner wrist overnight. We didnt abstain at all before.
Does this mean our tests results were inaccurate do you think?
Or is the book update a change from the previous method?
We drink/use raw milk only. We have been using homemade raw milk kefir and whey for a year now.
Also in this book, NCM encourages one to start stage one for the Intro diet with whey if you are not sensitive.
What do you think about this?
I have another dairy question….My 27 yo daughter just gave birth to her third child and is doing GAPS under Dr. Cowan. What are your thoughts on her being totally off dairy as she is nursing this newborn? She does get Calcium from the bone broths and A and D from Cod liver oil.
Thanks!

Hi Meredith,
I’m sorry that I can’t answer questions about Dr Natasha’s presentations, only because I am not her. Certainly I support the information presented by Dr Natasha and when she says now that many folks can start early in intro with whey, that is the case. Folks can try that and if they are sensitive to it (as Dr Natasha says some are), they can follow the more careful steps of complete abstinence from all dairy for six weeks, then progress from there.
It is fine to be off dairy while feeding a newborn. (ie. Ingesting dairy does not help us create milk.) For all other information regarding GAPS while pregnant or nursing, please see: http://gapsguide.com/book/book-updates/
Thanks so much for your question: It lets me know to update this particular page to include the new instruction around whey.
All my best,
Baden
I have dairy goats and make raw cheese every day. soft spreadable cheese and feta. Can you use these cheeses on GAPS and can you use the whey from these cheeses?
Hi Donna,
Only aged/fermented cheeses are approved for GAPS.
For the list of approved/not approved foods, please see the food list. For info on why a given food might or might not be included on GAPS, please see this post.
All my best,
Baden
