On GAPS, cholesterol comes up in conversations about eggs, animal fats, organ meats and the body’s need for nourishment. Gut and Physiology Syndrome gives it several jobs: cell structure, nervous-system function, steroid hormones and tissue repair. This guide focuses on the structural and brain discussion, then brings the book’s food examples back to an ordinary meal plan.[1]
Cells Need Cholesterol
Cholesterol is part of human cell membranes. A membrane is the boundary around a cell; human cells do not have the rigid cell walls found in plants or bacteria. The book’s structural argument is about the material used in these membranes and the different needs of different tissues.[1][3]
The biological role and a laboratory result are separate questions. “The body needs cholesterol” does not mean “the highest blood cholesterol is best.” For steroid hormones and repair, use the companion guide.
The Brain and Myelin
Campbell-McBride describes the brain as particularly rich in cholesterol and discusses myelin, the fatty insulation around many nerve fibers. She connects cholesterol availability with the formation and maintenance of these structures. This is part of her explanation for emphasizing nourishing animal foods.[1]
That does not make every nerve fiber myelinated or turn a food list into a treatment plan for multiple sclerosis. A particular neurological condition has its own clinical and source context; this page explains a material the nervous system uses.
Cholesterol and Synapses
The book also discusses synapses, the connections through which nerve cells communicate. A primary experiment by Mauch and colleagues found that cholesterol carried in ApoE-containing lipoproteins promoted synapse formation in cultures of purified central nervous system neurons. ApoE is a transport protein, not a form of cholesterol.[2]
That experiment helps clarify the biology. It was a cell-culture study, not a trial showing that a particular number of eggs improves a child’s learning or treats memory loss in every older adult. The book’s broader food argument and the experiment’s actual finding should not be treated as identical.[1]
Pregnancy, Babies and Cholesterol
The GAPS book emphasizes cholesterol during development and discusses its presence in breast milk. These passages belong within the wider pregnancy and infant-feeding guidance. They are not instructions to change a baby’s formula or introduce a high-cholesterol food ahead of the Baby GAPS sequence.[1]
For those decisions, use Baby GAPS first foods and weaning and the breast-milk and formula guide. The pregnancy and breastfeeding guide keeps the parent’s phase separate from the baby’s food introductions.
Food Examples in the Book
| Food Group | Examples Named by the Source | Keep the Food Context |
|---|---|---|
| Organ meats | Liver, kidneys, heart, tongue, tripe and poultry giblets | Use the food form and preparation appropriate to the phase. |
| Eggs | Fresh egg yolks | Follow the egg introduction and tolerance context. |
| Fish and seafood | Fish roe, coldwater fish and shellfish | Choose the actual permitted ingredient and preparation. |
| Dairy and animal fats | Butter, lard and other animal fats | Keep dairy tolerance and introduction separate from fat content. |
| Other source examples | Animal brains and cod liver oil | These are examples in the chapter, not a universal shopping list or supplement serving instruction. |
The source’s milligram comparisons use a 100-gram basis, which is not a normal serving for every food and certainly not a cod-liver-oil dose. For a family menu, choosing the food and its permitted form is more useful than trying to eat the top-ranked item or treat the comparison as a daily target.[1]
Make the Food List Usable
Start with an actual meal you can prepare. Our Full GAPS meal guide gives examples of combining permitted foods; the food list provides the phase boundaries. Adding an organ-meat dish to your cooking rotation is a different task from interpreting a lipid panel.
In our house, the daily pot of meat stock is what made GAPS doable. It starts first thing in the morning so everyone can drink it or have soup through the day, and the ingredients change with the budget, time and what is available. The daily-rhythm guide describes that practical family routine.
The Book’s Diet-Heart Position
Campbell-McBride strongly disputes the diet-heart hypothesis and directs readers to her separate book Put Your Heart in Your Mouth for that argument. This is her position; the biological need for cholesterol does not, on its own, settle a reader’s cardiovascular risk or prescribed treatment.[1]
For the source’s medication and behavior discussion, continue with the low-cholesterol and statin guide. Keep an actual result, treatment purpose and health history together rather than using this food table to decide whether to stop a medicine.
If the practical gap is knowing how to cook the organ meats named in the book, my course is the closest companion. The Organ Meats Made Easy course is listed in my course catalog.

- Processed oils, spreads and labels
- The two parent essential fatty acids
- Omega-3 food sources
- Omega-6 fats and their derivatives
