Ancestral Diets for Hormonal Balance: What Traditional Women Ate
Modern women are told that hormonal imbalance is simply a fact of life, a consequence of aging, stress, or genetics. Yet when researchers examine the historical and anthropological record, a different story emerges. Traditional cultures around the world consistently produced women with robust reproductive health, minimal menstrual dysfunction, and smooth transitions through menopause. The variable was not genetics. It was food.
Understanding what ancestral women ate, and why it worked, is not a nostalgic exercise. It is an evidence-grounded framework for restoring the nutritional conditions under which female hormones actually function. The science is real, the findings are reproducible, and the implications are difficult to ignore.
The Weston A. Price Framework: Fieldwork That Changed Nutritional Science
In the 1930s, dentist and researcher Dr. Weston A. Price traveled across fourteen isolated traditional cultures (Swiss mountain villagers, Gaelic islanders, Maasai pastoralists, Inuit communities, and others), meticulously documenting diet, physical development, and health markers. His 1939 book Nutrition and Physical Degeneration catalogued what he found: populations eating their native diets experienced virtually no cavities, narrow faces, or chronic degenerative disease. Women in these communities showed high fertility, uncomplicated pregnancies, and healthy offspring without the menstrual disorders that were already becoming common in industrialized societies.
What these diets shared was not a single food but a nutritional pattern: high intake of fat-soluble vitamins, particularly vitamins A, D, and K2, derived from animal foods. Organ meats, bone marrow, raw dairy, and fermented fish were not incidental; they were prized. Liver was given preferentially to pregnant women and young girls in culture after culture. Price identified what he called "Activator X" (later confirmed by Dr. Kate Rheaume-Bleue and others to be vitamin K2) as a critical co-factor in nutrient absorption and skeletal development. The fat-soluble vitamins Price documented are not background players in female hormonal health. They are central to it.
Retinol, Estrogen Receptors, and the Overlooked Connection
Preformed vitamin A (retinol) is found exclusively in animal foods. Beta-carotene from plants is a precursor that the body must convert, and research published in The Journal of Nutrition has consistently shown that this conversion is highly inefficient in many individuals, particularly those with common polymorphisms in the BCMO1 gene. For women, this matters more than commonly understood: retinol directly interacts with estrogen receptor signaling pathways.
A body of research, including studies published in Endocrinology and reviewed by nutritional scientists such as Dr. Chris Masterjohn, demonstrates that retinoic acid, the active metabolite of retinol, modulates the expression of estrogen-responsive genes. Vitamin A deficiency has been associated with disrupted ovarian function, impaired follicle development, and dysregulation of the hypothalamic-pituitary-ovarian (HPO) axis. Traditional diets that included liver and other organ meats regularly supplied 10,000–50,000 IU of preformed retinol per serving, far exceeding what is found in modern supplementation or plant-forward diets. These women were not accidentally healthy; they were eating in a way that directly supported the hormonal machinery their bodies required.
Saturated Fat and Steroid Hormone Synthesis: The Biology Is Not Negotiable
Every steroid hormone in the human body (estrogen, progesterone, testosterone, cortisol, DHEA) is synthesized from cholesterol. This is not a contested point in biochemistry. The question is where that cholesterol comes from and whether the diet is providing the raw materials the endocrine system requires. Traditional diets were high in saturated fat from animal sources: tallow, lard, butter, bone marrow, and full-fat dairy. These foods supplied both dietary cholesterol and the fatty acid substrates involved in cell membrane integrity and hormone receptor function.
The low-fat dietary era, which began in earnest following the 1977 McGovern Report and the subsequent USDA Dietary Guidelines, fundamentally altered the nutritional landscape for women. Research published in the American Journal of Clinical Nutrition has shown that very-low-fat diets significantly reduce circulating sex hormone levels, including estradiol and testosterone. A 2021 review in Nutrients examined the relationship between dietary fat quality and female reproductive outcomes, finding that diets higher in monounsaturated and saturated fats were associated with better fertility markers compared to low-fat diets. The fat-phobia promoted to women for decades was not neutral nutritional advice. It was a measurable disruption to hormonal substrate availability.
The Fat-Phobia Era and the Rise of Hormonal Dysfunction
The timing of rising hormonal disorder rates in Western women tracks closely with the broad adoption of low-fat dietary guidelines. According to Statistics Canada data, polycystic ovary syndrome (PCOS), now estimated to affect 8–13% of reproductive-age women, has become one of the most common endocrine disorders in the country. Endometriosis diagnoses have similarly increased, with the Endometriosis Society of Canada estimating that approximately 1 in 10 Canadian women are affected. Researchers including Dr. Lara Briden, a naturopathic physician and author of Period Repair Manual, have documented the dietary and environmental factors contributing to these trends, pointing specifically to the displacement of animal fats by refined vegetable oils and carbohydrates.
Dr. Paul Saladino, physician and author of The Carnivore Code, has written and spoken extensively on the relationship between ancestral animal-based nutrition and hormonal health, arguing that the displacement of nutrient-dense organ meats by processed foods has left modern women chronically deficient in the specific co-factors (retinol, zinc, copper, heme iron) that underpin reproductive endocrinology. While not every claim in the ancestral nutrition space is supported by randomized controlled trial evidence, the epidemiological trajectory and the mechanistic plausibility of these arguments are difficult to dismiss.
Key Nutrients in Traditional Female Diets: Food Sources vs. Modern Supplements
Ancestral women obtained their hormonal co-factors through whole animal foods. Liver delivered retinol, B12, riboflavin, folate, copper, and CoQ10 in tightly integrated, bioavailable form. Bone marrow supplied fat-soluble nutrients alongside collagen precursors. Raw dairy in traditional cultures provided vitamin K2, CLA, and cholesterol in a food matrix that bears little resemblance to the skimmed, homogenized product lining modern grocery shelves.
For women today who cannot or do not eat organ meats regularly (and research suggests the vast majority do not), a meaningful comparison arises between isolated synthetic supplements and desiccated whole-food organ concentrates. Synthetic retinyl palmitate provides retinol in isolation. A whole-food liver concentrate, by contrast, delivers retinol alongside the copper, riboflavin, and choline that govern its downstream metabolism. This is why products like the Rise Nutrition Women's Formula are formulated using freeze-dried grass-fed organ concentrates rather than isolated synthetic vitamins: the nutrient relationships that existed in the food are preserved in the supplement. It is the closest modern analog to eating the organ itself.
Zinc, Copper, and the Overlooked Architecture of Progesterone Production
Progesterone insufficiency (sometimes called luteal phase defect) is among the most underdiagnosed contributors to irregular cycles, PMS, and early pregnancy loss. Progesterone synthesis in the corpus luteum depends on a chain of enzymatic reactions that require zinc and copper as co-factors. Ancestral diets supplied both minerals in abundance through red meat, liver, and shellfish. Oysters alone deliver more zinc per gram than any other food. The Maasai, whose diet Price documented as consisting largely of blood, milk, and meat, showed robust fertility and minimal menstrual dysfunction, a population-level observation consistent with adequate zinc and copper status.
Modern Western diets, by contrast, are frequently zinc-depleted due to reliance on plant-based sources where phytic acid inhibits absorption. A 2020 systematic review published in Biological Trace Element Research found that women with PCOS had significantly lower serum zinc levels than healthy controls, and that zinc supplementation improved hormonal parameters including free testosterone and DHEA-S. These are not isolated findings. They point to a coherent nutritional framework in which specific mineral deficiencies downstream of dietary change are producing measurable hormonal consequences.
Rebuilding the Ancestral Nutritional Foundation
The lesson from traditional cultures is not that modern women should adopt any single ancestral diet wholesale. Price documented healthy populations eating wildly different macronutrient ratios, from the near-carnivorous Inuit to the grain-supplemented Swiss. What they shared was the consistent presence of nutrient-dense animal foods, particularly organ meats, and the near-total absence of refined vegetable oils, added sugars, and processed grains.
For Canadian women today, rebuilding this nutritional foundation means prioritizing grass-fed red meat, pasture-raised eggs, and, where tolerable, organ meats like liver and kidney. It means restoring dietary fat, including saturated fat from quality animal sources, as a legitimate and necessary component of hormonal nutrition. And for those who struggle to eat organ meats consistently, concentrated whole-food supplements offer a practical bridge. Rise Nutrition's Women's Formula was developed with this framework in mind, drawing on grass-fed bovine organ concentrates to deliver the retinol, heme iron, zinc, copper, and co-enzyme Q10 that ancestral diets provided as a matter of course.
Hormonal health is not a pharmaceutical problem with a pharmaceutical solution. It is, at its foundation, a nutritional problem, and the traditional cultures Price studied demonstrate that it has a nutritional answer. The science is there. The precedent is there. The only thing required is a willingness to look honestly at what women have always needed to thrive.
If you are ready to close the gap between what your hormonal system needs and what your current diet provides, explore the nutrient profile behind Rise Nutrition's Women's Formula, formulated specifically for the nutritional demands of female hormonal health, grounded in both ancestral practice and modern biochemistry.
