Raw-Food Diet

The premise

Heat changes food. Above roughly 118°F (~48°C), several things happen:

• Enzymes denature — many of the food’s own enzymes lose their structure
• Some vitamins degrade — vitamin C, folate, some B vitamins are heat-sensitive
• Some compounds form — Maillard reaction products, acrylamides, advanced glycation end-products
• Cell walls break down — making some nutrients more available, others less
• Water-soluble compounds leach — into cooking water if not consumed

Raw-food eating treats these changes as net-negative often enough to make uncooked the default. The argument is partly evolutionary (most life on Earth eats raw; humans cooked only the last few hundred thousand years) and partly biochemical (specific compounds and enzymes preserved by avoiding heat).

The counter-argument is also real: cooking made many foods edible and digestible, expanded what humans could eat, made calorie-dense diets possible (the cooking-and-brain-evolution hypothesis), and reduced certain pathogens and antinutrients. Both arguments have merit.

Forms

• Raw vegan (the modern default) — uncooked plants only; nuts, seeds, sprouted legumes/grains; fruits and vegetables; cold-pressed oils
• Raw vegetarian — adds raw dairy
• Raw omnivore — adds raw or lightly-cured fish (sashimi, ceviche), raw-cured meats (carpaccio, tartare, bresaola), raw eggs, raw dairy
• Living foods — broader umbrella that emphasizes sprouting, fermentation, and gentle dehydration alongside raw eating

Techniques

Raw-food preparation is its own craft, drawing on:

• Soaking and sprouting — activates dormant enzymes and reduces phytate content in nuts, seeds, legumes, grains
• Fermentation — enables raw cheeses, [[sauerkraut|sauerkraut]], kimchi, kefir, [[kombucha|kombucha]]; “preserved without heat”
• Cold-pressing — for oils, juices, plant milks
• Dehydration — at low temperatures (~115°F), for crackers, “breads,” fruit leather; preserves enzyme activity
• Spiralizing, blending, food-processing — for textures that compensate for the absence of cooking
• Marinating, curing, pickling — chemical “cooking” with acid or salt rather than heat

Raw-food kitchens often look more like a combination of a [[juice-bar|juice bar]], a fermentation lab, and a baker’s prep area than like a conventional kitchen.

Health and nutritional considerations

Well-planned raw-vegan diets can be adequate in the short and medium term but warrant attention to:

• Caloric density — easy to under-eat on raw vegetables; nuts, seeds, avocados, dried fruit needed for sufficient calories
• B12 — same issue as any vegan diet; supplement
• Iron, zinc, calcium — bioavailability lower from raw plant foods than from cooked; sprouting helps
• Protein — adequate from sprouted legumes, nuts, seeds in sufficient quantity
• Iodine, [[omega-3-fatty-acids|omega-3]] (EPA/DHA) — needs deliberate sourcing
• Some compounds become more available with cooking — lycopene from tomatoes, beta-carotene from carrots, some other carotenoids
• Dental health — high-fruit raw diets can be acid-erosive on enamel; sequencing and oral hygiene matter

Long-term-only-raw is uncommon in traditional populations (most traditional diets include cooked foods). Many practitioners use raw-heavy as a phase, or as 60–80% of intake, rather than 100%.

Cultural roots

Raw-food eating is older than the modern movement:

• Ann Wigmore (1909–1994), founder of the Hippocrates Health Institute and the Wigmore Living Foods Lifestyle, formalized the modern living-foods approach with wheatgrass, sprouts, fermented foods
• The European Lebensreform movement (late 19th–early 20th century) included raw-food advocates
• Sashimi, ceviche, tartare, carpaccio — multiple culinary traditions of raw animal foods
• Raw dairy — across Europe, India, the Middle East, and elsewhere; older than pasteurization
• Raw vegetable and fruit traditions — most cultures eat substantial amounts of raw produce; modern raw-foodism extends rather than invents this

Operators on the vault

[[raw-food-and-goods]] in the SF Bay Area is the canonical example currently — husband-and-wife produce delivery, all-organic curated variety packs, regenerative-organic-certified eggs, TikTok as discovery channel. Raw-food cafes, juice bars, and produce delivery services across other bioregions belong on the same surface.
