Paleo Diet

The premise

Three claims sit underneath paleo:

1. Mismatch hypothesis — modern diseases of civilization (obesity, type 2 diabetes, cardiovascular disease, autoimmune conditions) are at least partly the result of an evolutionary mismatch between the food humans evolved on and the food they eat now
2. Pre-agricultural reference — the ~2.5 million years of pre-agricultural human eating is treated as the closer-to-evolved-default; the ~10,000 years since the agricultural revolution is treated as a recent and incomplete adaptation
3. Specific exclusions — grains (especially gluten-bearing), legumes (lectins, phytates), dairy (lactose, casein), refined sugars, refined oils, and most processed foods are flagged as recent additions the body handles less well

Whether these claims are right in the strong form or only in part is contested. The clinical-trial evidence for paleo-style eating is mixed-but-generally-favorable for cardiovascular and metabolic markers in the short and medium term.

What paleo includes and excludes

Includes:

• Meat (ideally pasture-raised, [[grass-fed|grass-fed]], wild-caught)
• Fish and shellfish
• Eggs
• Vegetables (all)
• Fruit (often in moderation; some versions emphasize lower-sugar varieties)
• Nuts and seeds
• Healthy fats — [[avocado|avocado]], olive oil, [[coconut|coconut]] oil, animal fats from quality sources

Excludes:

• Grains (wheat, oats, rice, corn, etc.)
• Legumes (beans, lentils, peanuts, soy)
• Dairy (some practitioners include [[grass-fed|grass-fed]] butter or raw dairy)
• Refined sugar and most sweeteners (some include raw honey, maple syrup)
• Refined and industrial seed oils
• Most processed foods

Variants

The popular movement spawned several variants:

• Strict paleo — Cordain’s original, the longest exclusion list
• Primal — Mark Sisson’s variant, includes some dairy
• Ancestral health — broader umbrella, includes traditional-foods perspectives, often more inclusive of grains and dairy if properly prepared ([[sourdough|sourdough]], soaked, sprouted, fermented)
• Whole30 — 30-day strict elimination protocol; functions partly as a paleo on-ramp
• Carnivore — extreme variant; animal foods only; not what classical paleo prescribes
• Keto-paleo — paleo with deliberate carbohydrate restriction

Where paleo is strong

• The exclusion of [[ultra-processed-foods|ultra-processed foods]], refined sugar, and industrial seed oils overlaps heavily with [[whole-foods-diet]] recommendations
• Emphasis on vegetables, healthy fats, and quality protein is nutritionally robust
• The “ancestral” framing draws people’s attention to upstream questions about food origin and ecology
• For many people with autoimmune, gut, or metabolic conditions, the elimination protocol surfaces specific food triggers

Where paleo is contested

• Anthropological evidence shows pre-agricultural humans ate more diverse diets — including cultivated tubers, gathered grains and legumes in many regions, and substantial plant material — than the popularized “meat-and-vegetables” picture
• The categorical exclusion of legumes and properly-prepared whole grains has limited evidence; traditional preparations (soaking, sprouting, fermenting) address most antinutrient concerns
• Sustainability concerns: paleo as widely practiced relies on animal foods at frequencies that don’t scale to global populations without industrial-feedlot supply
• “Paleo-branded” packaged foods (paleo bars, paleo cookies, paleo shakes) are often ultra-processed and undermine the framework’s own logic

Vault stance

Where paleo overlaps with [[pasture-based-omnivory]] and [[whole-foods-diet]] — pasture-raised meat, vegetables, healthy fats, no ultra-processed foods, attention to upstream ecology — it is unambiguously aligned. Where paleo becomes “industrial-supplied meat-heavy eating” or “paleo-branded packaged products,” it has drifted from what makes the framework valuable.

The deeper conversation paleo opened — what did humans actually evolve to eat, and what do modern foods do to bodies optimized for different inputs — is worth the engagement. The dogmatic version of any answer is not.

Lenses still to grow

• The carnivore-diet offshoot — what to make of it
• Specific clinical trials of paleo-style eating
• The grain-and-legume question — traditional preparation, fermentation, and what changes
• Anthropology of pre-agricultural human diets in different regions (African, European, Andean, Pacific)
• Paleo and gut health, autoimmune protocol, AIP (autoimmune protocol)
• Cost and sustainability — who can practice paleo well
