(All content from our conversation – clean, organized, one continuous block)
PART 1: SEED OILS – WHAT THEY ARE & WHY AVOID THEM
What Are Seed Oils?
Seed oils are liquid fats extracted from plant seeds using industrial processes (heat, solvents like hexane, deodorization).
Common Seed Oils ("The Hateful 8")
- Canola
- Corn
- Soybean
- Sunflower
- Safflower
- Cottonseed
- Grapeseed
- Rice bran
Not Seed Oils (Safe Alternatives)
- Fruit oils: Olive, avocado, coconut
- Animal fats: Butter, ghee, lard, tallow, schmaltz
- Cold-pressed nut oils (small amounts): Almond, walnut, macadamia
Seed Oil FAQ
Is soy lecithin a seed oil? No – phospholipid byproduct of soybean oil. Contains ~35% soybean oil. Avoided in seed-oil-free diets.
Is sunflower oil a seed oil? Yes – from sunflower seeds.
Is avocado oil a seed oil? No – from fruit pulp.
Is canola/vegetable oil seed-based? Yes – canola from rapeseeds; “vegetable oil” = seed oil blends.
Oil from freshly ground peanut butter? Yes – peanut oil from peanut seeds. Natural but high omega-6.
Oil from ground almonds? Yes – almond oil is a seed oil (almond = seed). Less processed = better, but limit.
PART 2: SEED OILS & TESTOSTERONE – THE SCIENCE
Why Seed Oils May Lower Testosterone
1. High Omega-6 (Linoleic Acid → Arachidonic Acid) → inflammation → Leydig cell damage
2. Oxidative Stress → PUFAs oxidize → harms testicular tissue
3. Endocrine Disruption → phytoestrogens (soy), xenoestrogens (fryer plastics)
4. Vitamin E Depletion → burns antioxidants needed for T synthesis
Key Studies
Rat studies: High PUFA (corn/soy oil) → ↓ T, ↓ sperm vs. saturated fats
Iranian men (n=100): Higher PUFA:LA → lower total T
NHANES: Top 25% linoleic acid intake → ~15% lower T
8-week swap (seed oil → butter/olive): +18% free T in trained men
Modern intake: 10–20x ancestral (5–10% vs. <1% of calories)
Your n=1 Experiment
Old diet (seed oils) → low energy/mood/libido
New diet (no seed oils) → improved health
Your body is the best lab. Keep tracking.
PART 3: THE RUSSIAN DIET – A SEED-OIL-FREE BLUEPRINT
Why Russia?
- Zero industrial seed oils
- Uses butter, sour cream, lard, salo
- Fermented foods → gut health
- Hearty, hormone-supportive, built for strength
Health Edge vs. Western Diet
- Lower processed carbs
- Higher nutrient density
- Better omega-6:3 ratio
- Ancestral resilience
Daily Macros (2,500 cal active male – adjust)
Fats: 35–45% – Butter, sour cream, salo, lard
Protein: 20–25% – Beef, pork, fish, eggs, tvorog
Carbs: 30–40% – Rye, buckwheat, potatoes, roots
Veggies/Fruits: Unlimited – Cabbage, beets, berries, mushrooms
