Hormonal Health Starts in the Kitchen: A Whole Food Guide

But hormonal dysfunction isn't inevitable. It's nutritional. And it's fixable by what you eat.

Cholesterol is the foundation of all hormones

Your body makes all steroid hormones (oestrogen, progesterone, testosterone, cortisol, DHEA) from cholesterol.¹ When your cholesterol is too low, your hormone production fails.

Cholesterol is the precursor for every steroid hormone the body makes — pregnenolone, progesterone, oestrogen, testosterone, cortisol, DHEA. Aggressive cholesterol lowering, whether through statin therapy or chronic low-fat eating, reduces the substrate available for that pathway. The hormonal side-effects reported in some statin users (libido changes, mood changes, fatigue) are consistent with that mechanism, even where causality in any individual case is hard to prove. The point isn't to tell anyone to abandon prescribed medication; the point is that if you have hormonal problems on a statin, that's a conversation worth having with your prescriber, alongside discussion of newer cardiovascular markers (ApoB, particle size, Lp(a), triglyceride/HDL ratio, fasting insulin) that the LDL-only model misses.

Your body needs cholesterol. Not excessive amounts, but adequate amounts. A healthy total cholesterol is 150-250 mg/dL. Below 150 and your hormones suffer.

Cholesterol comes from dietary fat, particularly saturated fat. Butter, eggs, meat, and dairy are rich sources. These aren't luxuries. They're foundational for hormone health.

Without adequate cholesterol, your body cannot make adequate hormones. Low-fat diets and statin drugs destroy hormonal health in women. This is not opinion. This is endocrinology.

Saturated fat is needed for hormone production

Saturated fat has been demonised, but your hormonal system requires it. Saturated fat is the substrate for hormone synthesis. It's also part of your cell membranes and is required for vitamin A and D absorption.

Butter, coconut oil, beef fat, and the fat in eggs and dairy are healthy saturated fats. They're what your ancestors ate for millennia without epidemic levels of hormonal dysfunction.

Modern seed oils (vegetable oil, canola oil, sunflower oil) are oxidised and inflammatory. They disrupt hormone signalling and increase oestrogen dysregulation. Replacing seed oils with butter and coconut oil transforms hormonal health.

The women with the most stable hormones eat full-fat dairy, butter-rich cooking, and beef fat. Not low-fat everything.

Cruciferous vegetables for oestrogen clearance

Oestrogen is made by your ovaries, but it's also recycled through your liver. If your liver function is poor, oestrogen recirculates instead of being excreted. This causes oestrogen dominance: too much oestrogen relative to progesterone.

Oestrogen dominance causes heavy periods, mood swings, breast tenderness, water retention, and fat storage around the hips and thighs. It's driven by poor oestrogen clearance, not by making too much oestrogen.

Cruciferous vegetables (broccoli, cabbage, kale, cauliflower) contain indoles and sulforaphane, compounds that support phase III liver detoxification, which is specifically the phase that clears oestrogen.²

Eating crucifers 3-4 times weekly significantly improves oestrogen balance. Cook them with fat to improve nutrient absorption.

Liver detoxification requires specific nutrients

Your liver's job is to detoxify hormones so they can be excreted. This requires phase I, phase II, and phase III enzymes. Phase I requires B vitamins and minerals. Phase II requires amino acids like glycine and taurine. Phase III requires sulphur-containing compounds.

If your liver isn't detoxifying efficiently, hormones recirculate and cause dysfunction.

Organ meats, particularly liver itself, provide the exact nutrients your liver needs to function. Beef liver contains B vitamins, iron, copper, and other cofactors required for detoxification.

Bone broth provides gelatin and glycine, which support phase II detoxification. This is why bone broth and liver together are so powerful for hormonal health.

Insulin dysregulation disrupts female hormones

When your blood sugar spikes and crashes repeatedly, your insulin becomes chronically elevated. High insulin drives excessive androgen production by your ovaries, causing acne, facial hair, and irregular periods.

This is the mechanism behind polycystic ovary syndrome (PCOS). It's insulin-driven ovarian androgen excess, not primary ovarian disease.³

Stabilising blood sugar stabilises insulin, which stabilises androgen production, which restores regular periods and clears acne. No medication needed if insulin is controlled.

Stabilising blood sugar means eating protein and fat with every meal, avoiding refined carbohydrates, and maintaining consistent meal timing.

PCOS is driven by insulin dysregulation, not ovarian disease. Fix your blood sugar and your periods become regular, your skin clears, and your hormones stabilise. Most PCOS is nutritional.

Thyroid hormones regulate metabolism and mood

Your thyroid produces T4 and T3, which regulate your metabolic rate, body temperature, mood, and energy. Hypothyroidism (low thyroid function) causes weight gain, fatigue, depression, and hormonal irregularities.

Thyroid function depends on iodine, selenium, iron, and zinc.⁴ Deficiencies in any of these cause hypothyroidism.

Beef liver, oysters, and fish provide selenium and iodine. Most people don't eat enough to support thyroid function.

Get your TSH and free T3 tested. If your TSH is elevated and free T3 is low, improve your mineral status before assuming you need thyroid medication.

Progesterone requires adequate nutrition

Progesterone is the calming hormone. Without adequate progesterone, you experience anxiety, sleep disruption, and mood instability, especially in the luteal phase of your cycle.

Progesterone production requires cholesterol, adequate body weight (fat cells produce oestrogen, which supports progesterone production), and vitamin B6 (a cofactor for progesterone synthesis).

Women who restrict calories too aggressively often become progesterone-deficient, which manifests as horrible PMS, anxiety, and insomnia. Eating more, not less, often fixes this.

Beef liver and other meats provide B6. Adequate dietary fat supports cholesterol availability. Together these support progesterone production.

The protocol for hormonal health

• Eat organ meats 2-3 times weekly. Beef liver provides all the nutrients your liver and hormones need.
• Eat red meat 4-5 times weekly. Provides iron, B vitamins, and cholesterol (yes, dietary cholesterol supports hormone production).
• Eat fat with every meal. Butter, olive oil, coconut oil, beef fat. Don't fear saturated fat.
• Eat cruciferous vegetables 3-4 times weekly. Broccoli, cabbage, kale support oestrogen clearance.
• Drink bone broth 3-4 times weekly. Supports liver detoxification and provides glycine.
• Eliminate seed oils. Replace with butter, olive oil, coconut oil. Seed oils disrupt hormone signalling.
• Stabilise blood sugar. Eat protein and fat with every meal. Avoid refined carbohydrates.
• Get mineral testing. Zinc, selenium, iodine, iron. Supplement if deficient.

Oestrogen metabolism and the microbiome

Your microbiome directly affects oestrogen metabolism. Beneficial bacteria (particularly Bacteroides fragilis) produce beta-glucuronidase, an enzyme that breaks down and recycles oestrogen through the enterohepatic circulation.⁵

When your microbiome is healthy, oestrogen is recycled efficiently, which prevents oestrogen dominance. When dysbiosis occurs from antibiotics, poor diet, or stress, oestrogen recirculates and accumulates, causing oestrogen-dominance symptoms.

This is why fermented foods and fibre are so important for hormonal health. They feed the bacteria that metabolise oestrogen properly.

PMS and nutritional deficiency

Premenstrual syndrome is fundamentally a nutritional disorder. Women with adequate magnesium, calcium, B vitamins, and protein experience minimal PMS. Women with deficiencies experience severe symptoms.

The luteal phase of your cycle (after ovulation) requires extra magnesium for mood stability and calcium for water retention prevention. Without these minerals, PMS is severe.

Magnesium supplementation and bone broth (rich in minerals) during the luteal phase transforms PMS from debilitating to manageable or gone.
