GAPS Dairy Introduction: The Seven Steps Explained

GAPS has two ways of introducing dairy. Homemade fermented dairy can enter during the six-stage Introduction Diet when it is tolerated. The separate Dairy Introduction Structure is for people who could not introduce dairy during Intro, or who started directly on Full GAPS. Finding your route first makes the product order much easier to follow.^[1]

In our family, we followed the GAPS dairy guidance using raw dairy from a local farm, and it went well. We usually make yogurt, kefir, ghee and sour cream in weekly batches. That is our experience, rather than a timetable for another family. Below, you can see the separate seven-step structure and how it differs from dairy introduction during Intro.

What the GAPS Dairy Introduction Structure Is

Dr. Natasha Campbell-McBride describes the structure in the Full GAPS chapter of Gut and Physiology Syndrome. It is intended for people who showed a reaction to dairy on the book’s Sensitivity Test and could not introduce it during Intro, and for people who chose to begin with Full GAPS. The official GAPS summary also notes that people with eczema, asthma or allergies may benefit from leaving dairy out even when starting Full GAPS.^[1][2]

The official summary says completing this structure from Full GAPS can take up to 18 months. That is an estimate, not a deadline. The book says some people need much longer before protein-containing dairy is tolerated, and some must continue avoiding dairy protein indefinitely.^[2][3]

How It Differs From Dairy During Intro

The separate structure is not a seventh Intro stage. During Stage 1, the book starts dairy introduction with whey dripped from homemade yogurt, after its Sensitivity Test. Yogurt and yogurt-cultured sour cream follow gradually, then kefir. Fermented vegetable juice is another probiotic-food option. Homemade ghee enters at Stage 2. If dairy is already introduced, the book starts ghee at a few tablespoons per day; if dairy is not yet introduced, it starts at one teaspoon per day. Both amounts are increased gradually. These are the Intro amounts, separate from the structure’s Step 2 instructions.^[4]

These are different starting routes. Someone already tolerating suitable fermented dairy during Intro does not need to restart it at a teaspoon a day. The book explicitly allows the usual amounts to continue when fermented dairy was already eaten without negative reactions.^[4] Our probiotic-food introduction guide gives the Stage 1 amounts.

The Seven Steps of Dairy Introduction

This checklist follows the seven-step summary in Campbell-McBride’s 2020 book. The starting amounts differ, so the observation instructions stay beside the food they apply to.^[5]

1. Avoid All Dairy for 4–6 Weeks. This is the first step of the separate structure, before introducing ghee. Campbell-McBride describes this as a period for clearing the effects of commercial dairy. It is not an instruction to add ghee while still at Step 1.
2. Introduce Homemade Ghee. The summary specifies organic raw butter, preferably cultured butter. Begin with one teaspoon of ghee with a meal, then observe your symptoms for 2–3 days. If usual symptoms have not worsened and old symptoms have not returned, gradually make it a regular food. If you react, the book says to wait a few months before trying again.
3. Introduce Raw Organic Cultured Butter. Try one teaspoon with a meal and observe for 2–3 days. If tolerated, increase gradually. Once cultured butter is well tolerated, the next form to try is ordinary butter made from unfermented cream.
4. Introduce Yogurt-Culture Dairy. Use homemade yogurt and sour cream made from raw organic milk and cream with yogurt culture. Start with one teaspoon per day and increase gradually. The summary describes working toward at least a cup according to taste and desire; the preceding explanation gives one or two cups of yogurt a day as an amount to build toward. This is not the starting portion.
5. Introduce Kefir-Culture Dairy. Once yogurt and yogurt-cultured sour cream are well tolerated, introduce homemade milk kefir and cream fermented with kefir culture. Start at one teaspoon per day and increase gradually. Continue the tolerated yogurt and sour cream while introducing kefir.
6. Introduce Homemade Cottage Cheese. The book describes cottage cheese made by dripping homemade yogurt or kefir through cheesecloth overnight. Introduce it gradually. It does not give this step the same fixed teaspoon-and-2–3-day schedule as ghee and butter.
7. Introduce Natural Traditionally Made Cheese. Try commercially available natural cheese, one variety at a time. The preceding explanation says to begin with no more than one mouthful and watch the response. Cheddar and Parmesan are examples, rather than a requirement to eat every cheese on a list.

The longer explanation recommends trying butter after about six weeks on the diet for sensitive people. Once ghee and butter are well introduced, it describes protein-containing dairy as possible in 6–12 weeks’ time, while stressing that readiness varies. Those passages do not make every step six weeks long.^[3]

Why Ghee Comes Before Protein-Containing Dairy

The book describes ghee as milk fat containing virtually no milk protein or lactose. Butter contains small amounts of whey, so it is a different step. Yogurt, sour cream, kefir and cheese bring protein-containing dairy further into the diet. Campbell-McBride connects this order with digestive recovery and the ability to digest milk protein rather than absorb opiate-like casein fragments called casomorphins.^[3]

Campbell-McBride also allows purchased ghee if it has no preservatives or other additives, while preferring homemade ghee so its purity is known. She emphasizes ghee and butter’s fatty acids, vitamins A, D, E and K2, and beta-carotene. Her butter guidance prefers unsalted organic butter because processed salt and other additives can accompany salted butter.^[3]

Ghee is still made from dairy. The book says some people with severe dairy allergy cannot tolerate even ghee, and explicitly excludes butter and ghee when there is an anaphylactic-type allergy. Its generally good tolerance is not a promise for everyone.^[3]

Use our stovetop ghee recipe for the complete preparation method. The official FAQ permits pasteurized butter for making ghee, although the seven-step book summary prefers organic raw cultured butter.^[6]

Why Yogurt Comes Before Kefir

Yogurt and kefir are different cultures. Campbell-McBride describes kefir as a more powerful combination of bacteria and fungi, including beneficial yeasts, and says it usually produces a stronger die-off reaction. That is her reason for introducing yogurt first. She also describes the beneficial yeasts in kefir as helping control pathogenic yeasts, including Candida. Cream fermented with yogurt culture belongs with yogurt; cream fermented with kefir culture belongs with kefir.^[7]

Our 24-hour GAPS yogurt method covers making a batch. Getting a batch ready and deciding how much to introduce are separate jobs. A full jar in the fridge does not change the book’s small starting amount.

Cottage Cheese and Natural Cheeses

Cheese concentrates milk protein and, in Campbell-McBride’s explanation, can be difficult for people who do not tolerate the yeasts and molds involved. She describes people who tolerate homemade yogurt but never tolerate cheese. Introduce one cheese at a time rather than treating Step 7 as permission for every variety at once.^[7]

The book describes trying additive-free commercial live natural yogurt, sour cream and crème fraîche a few months after cheese has been introduced successfully. Its later discussion places fresh cream toward the end of the second year and says some people can eventually introduce raw organic milk. After two years on the diet, the book says many people find they can occasionally tolerate natural dairy products beyond the allowed list. Campbell-McBride recommends keeping those foods occasional and staying mainly with the allowed dairy products. These are later possibilities, not foods to add at the beginning.^[7]

Raw and Pasteurized Dairy in the GAPS Guidance

The book prefers raw organic milk from native breeds raised on organic pasture. It names Jersey, Guernsey, Ayrshire, Shorthorn and British Friesian cows, as well as milk from other animals. When raw organic milk cannot be found, it allows pasteurized organic milk from natural cow or goat breeds for home fermentation. In her clinical observations, some people who reacted to non-organic yogurt tolerated organic yogurt. She attributes the difference to chemicals in non-organically produced milk.^[7] That fallback is different from drinking pasteurized milk as milk.^[8]

Our milk and dairy guide explains lactose, casein and sourcing in more detail. Ask your supplier about the animal, its feed, processing and added ingredients so you know what you are working with.

Dairy Tolerance and the Sensitivity Test

Campbell-McBride’s home Sensitivity Test places a drop of homemade yogurt, sour cream or kefir on the inside of the wrist at bedtime, lets it dry and checks the spot in the morning. An angry red reaction is the book’s reason to leave dairy out of Intro and consider the separate structure later. She recommends using this observation step for new dairy products.^[8][2]

A clear wrist spot does not rule out milk allergy or establish that eating the dairy is safe. Food-allergy diagnosis uses clinical history and appropriate testing; the book’s home observation is not a substitute for that process. Its anaphylactic-type allergy exception still applies.^[9][3]

While introducing a food, watch for the person’s usual symptoms. The book names increased joint pain, sleep disturbance, anxiety, mood changes, hyperactivity, bed-wetting in a potty-trained child, eczema flares and worsening allergies. It says some long-standing mental-health conditions, epilepsy, autoimmune disease, severe asthma and severe eczema may require avoiding dairy protein indefinitely.^[3]

The official summary says a negative response means that dairy product should wait until more healing has taken place. Pause the new product rather than increasing it through a worsening response. The observation period is there to inform the next step, not to make you finish it on a particular day.^[2]

How This Fits Your Current Plan

If dairy is already tolerated during Intro, continue that route. If it was excluded or you started directly on Full GAPS, use the separate structure and identify your current step. Write down the product, amount, date and response before changing the next food. The book recommends keeping a food-and-symptom diary through Intro and beyond.^[1][4][10]

For constipation, the book distinguishes high-fat dairy such as ghee, butter and sour cream from higher-protein whey, yogurt, kefir and cheese, which can aggravate constipation in some people. For diarrhea, it emphasizes fermented dairy from early Intro when tolerated. This is another reason to record the exact dairy form, rather than only writing “dairy” in a diary.^[8]

Frequently Asked Questions

Does Fermenting Milk Make It Dairy-Free?

No. Yogurt, kefir, cultured cream and cheese remain dairy foods. The book’s FAQ also says some lactose remains in fermented dairy, even aged cheese, and that the amount varies by batch. “Largely lactose-free” is not a guarantee of zero lactose.^[6]

Can I Use Vegetable Ferments While Dairy Is Out?

Yes. Stage 1 includes juice from homemade fermented vegetables as a probiotic-food option. It has its own introduction amounts and does not establish dairy tolerance.^[4]
