The Seed-Oil Evidence, Mapped (2026)
Map essential LA, RCT vs observational tension, frying oxidation, and pattern-first swaps—without purity cults.

Buying Organic Dairy and Meat: Practical Rules (2026)
Budget rules for organic milk, eggs, and meat—where labels matter, where protein density wins, no halo junk.

Seed Oils in Special Populations: Pregnancy, Secondary Prevention, and Clinical Context
Essential FA needs, secondary-prevention trial limits, and frying exposure differ by clinical context—not by internet purity contests.

Ramsden Reanalyses of Seed-Oil Era Trials: Sydney Diet Heart and Minnesota Coronary
Recovered data show pure high-linoleic interventions did not deliver the mortality free lunch mid-century narratives promised.

Nutrition
Seed Oils on Sex Axes: Men, Women, Pregnancy, and What Trials Show
Men convert less ALA to EPA/DHA; pure-LA harm signals were male-heavy; pregnancy needs DHA—not zero linoleic acid.

Seasonal and Regional Eating Decision Framework: Evidence vs Romanticism
Local and seasonal food can raise produce intake and cut some emissions—but is not automatically more nutritious or safer.

Organic Foods Sex Axes: Why Pregnancy and ART Change the Priority Stack
More produce still wins; organic’s highest-value window is exposure reduction in pregnancy and ART.

Dirty Dozen and Clean Fifteen: Useful Budget Tool or Overstated Hazard List?
Residue rankings can triage organic spend—but they are not proof that conventional Dirty Dozen produce is illegal or toxic at residue doses.

Organic Cost Premium: Affordability Decision Framework
Premiums often run tens of percent by item. Health gains are residue- and preference-mediated—not a multivitamin substitute. Budget frameworks beat all-or-nothing identity shopping.

Nutrition
Organic Food, Cadmium, Heavy Metals, and Mycotoxins
Organic status is not a heavy-metal free pass. Cadmium tracks soil and crop more than seal alone; some organic systems can show higher mycotoxin risk when fungicides are restricted—context or crop-specific.

Nutrition
Organic Dairy and Meat: Fatty Acid Profiles and Limits
Organic and pasture-linked ruminant products often show higher omega-3 and CLA on average—effect sizes are modest relative to eating fish or overall pattern. Antibiotic and hormone rules differ by standard.

Actionable One-Carbon Nutrition Without MTHFR Genotype
You do not need a SNP to take folic acid for pregnancy, fix B12 deficiency, or eat leafy greens. Grade A actions are phenotype- and life-stage-driven.

Ochratoxin and Food Mycotoxins: Dose Context Deep Dive
Ochratoxin A in grains, coffee, wine, and dried foods is a food-safety contaminant problem with regulatory limits—not proof that a damp bedroom equals dietary toxin dosing.

Iron Overload Diet Modifiers and Hard Avoidances
Diet is adjunct, not cure. Phlebotomy removes ~250 mg iron per unit weekly versus ~2–4 mg/day absorption swing. Hard stops: iron pills, vitamin C pills, raw shellfish, and alcohol with liver disease.

Swapping Seed Oils: What to Fix First (2026)
Pattern first, then fry-oil quality, then home cooking fats—without purity-cult grocery panic.

Paul Saladino's Claims, Graded by Evidence (2026)
Animal-based claims graded A–D: protein kernels kept, fruit-only carbs nuance, organ hype and seed-oil absolutism constrained.

Women’s Seasonal Eating: Iron, Energy Availability, and Cycle Realities
Women’s seasonal patterns should protect iron, energy availability, and produce intake—not cycle-sync food superstition. Menstruation, training, and winter light interact with fueling.

Seed Oil Processing: Hexane Extraction, Refining, and 3-MCPD/GE Contaminants
Residual hexane in finished oils is typically very low. The sharper process issue is 3-MCPD esters and glycidyl esters from high-temperature deodorization—mitigable, not unique to “seed oil” branding.

Nutrition
Seed Oils, Linoleic Acid Intake Norms, and Essential Fatty Acid Guidelines
Linoleic acid is essential (~1–2%E prevents deficiency). AMDRs and AHA guidance support replacing saturated fat with PUFA including LA—not industrial oil maximalism or elimination absolutism.
