πŸ₯« Food When It's Scarce: Storage, Rationing & Nutrition

How to keep a household fed for a year or more with no stores: how much food people need, what to store and how to keep it good for decades, how to share it out fairly, how to prevent the hunger diseases, how to refeed someone who is starving, how to keep babies alive, and what wild food the Illinois Valley gives month by month. The books are in Food-Security\ (Storage-Rationing, Nutrition-Deficiency, Foraging). Growing, milling and cooking staples are in Food-From-Scratch\, and cellars and drying in Food-Storage\.

⚠️ Rules that prevent the worst outcomes


🍽️ How much food people need

Daily needs (US official tables; "active" there only means walking over 3 miles a day β€” wood, water and hand-digging are heavier, so plan from the top of each range) (Dietary Guidelines, pp. 153–154; protein p. 146, p. 148):

Person Calories a day Protein a day
Man, 19+ 2,200–2,600 inactive; 2,800–3,000 active 56 g
Woman, 19+ 1,600–2,000 inactive; 2,000–2,400 active 46 g
Teen boy up to 3,200 52 g
Child 9–13 β€” 34 g
Child 2–8 1,000–2,000 13–19 g
Pregnant +340 (2nd trimester), +452 (3rd) 71 g
Nursing +330 (first 6 months), +400 after 71 g

Plan on 2,100 kcal per person per day, averaged over all ages, with at least 10–12% from protein and 17% from fat (WHO 2002, p. 6; Sphere, p. 228) β€” at least 53 g protein and 40 g fat (Sphere, p. 260).

Adjust it (WHO 2002, pp. 11–13):

What 2,100 kcal looks like: 400 g cereal (about 2 cups dry), 60 g beans, 25 g oil (2 Tbsp), 50 g fortified flour, 15 g sugar, 5 g iodized salt = 2,113 kcal, 58 g protein (WHO 2002, p. 14). For a year: about 322 lb grain, 48 lb beans, 20 lb oil, 12 lb sugar, 4 lb salt per person (our arithmetic).

Handy number: 790 g (1.74 lb) of dry wheat gives 2,600 kcal and 103 g protein β€” so 1 lb of dry grain β‰ˆ 1,500 kcal (Kearny, p. 90).

πŸ“‹ A year's food: the list and a worked example

BYU's one-year list for one adult (BYU, p. 1), and the same for 2 adults + 2 children under 8, who count as about 3 adults (children under 8 need about half β€” USU, p. 65):

Item 1 adult Household (Γ—3) Sealed shelf life
Wheat 132 lb ~400 lb 30+ years
White rice 65 lb ~195 lb 30+ years
Rolled oats 29 lb ~87 lb 20 years
Pasta 21 lb ~63 lb β€”
Beans, peas, lentils 62 lb ~186 lb 25 years
Nonfat dry milk 60 lb 180 lb 15 years (cool)
Sugar or honey 70 lb 210 lb 30+ years
Iodized salt 8 lb 24 lb 30+ years
Cooking oil 2 gallons 6 gallons about 1 year
Butter (frozen), peanut butter 6 lb each 18 lb each β€”

That is roughly 2,200 kcal a day (our rough arithmetic). Also: baking soda, baking powder, yeast, can openers, a grain grinder (hand mill and metate, FAO p. 17), and recipes that use only stored food. USU's simpler rule: about 300 lb of grain per person per year, 25–60 lb of it rice (USU, p. 68).

Fill the gaps (rule of thumb): vitamin C tablets (multivitamins keep less long β€” BYU), vitamin D or cod-liver oil, extra iodized salt, whole grains and beans (not only white rice and flour), seeds to sprout, and a plan for fat once the oil goes rancid (lard, oil seeds, animals).

πŸ“š Go deeper: BYU Longer-Term Food Storage β€” the one-page table; USU Food Storage for Emergencies, p. 65 β€” wheat, rice, oats and beans chapter by chapter.

πŸ“¦ Storing it for years

Heat is the main enemy. Keep food at 40–70 Β°F. In BYU research, wheat stayed good 25 years in a cool basement but only 5 in a hot garage or attic. Keep containers off bare concrete (USU, p. 31). Our summers pass 100 Β°F and sheds get hotter β€” use the coolest inside room or a cellar (Root Cellar guide).

Keep grain dry. Above 12% moisture it starts to break down, above 15% it molds, at 20% bacteria grow. Freezing does not harm it (USU, p. 66). Seal it in the dry season (July–September), not in wet winter air (rule of thumb).

Packing with oxygen absorbers (USU, p. 98):

  1. Use oxygen-tight containers only: #10 cans or Mylar/foil bags. Plastic buckets slowly let oxygen in β€” put a Mylar bag inside the bucket; the bucket keeps rats out.
  2. Absorber size: 100 cc per quart jar, 300 cc per gallon bag or #10 can, 2,000 cc per 5-gallon bucket. (Some charts say 500 cc, but a full bucket of grain holds about 1,500 cc of oxygen (arithmetic); extra absorber does no harm.)
  3. Work fast: an opened pack starts in 20 minutes and is spent in about 5 hours. Reseal spare packets in a small jar. Label every bag with contents and date.

A plastic bucket cut away to show a sealed Mylar bag of dry grain inside it, with an oxygen absorber packet on top of the grain, and a table of absorber sizes The Mylar bag keeps oxygen out and the bucket keeps rats out; the absorber goes in just before you seal (a diagram drawn for this guide).

Bugs (USU, p. 95): oxygen held under 1% for 12 days kills every stage, so Mylar with absorbers kills weevils (the common grain pests, FAO p. 78). Dry ice: 3–4 inches of grain in a bucket, 2–3 oz crushed dry ice, fill, lid loose 30 minutes, then seal (p. 66). Freeze 2–3 days, warm a day, freeze again. Heat in a 130 Β°F oven for 30 minutes β€” but heated grain will not sprout, so never heat seed grain.

Sealed, low-oxygen Keeps (USU)
Wheat good bread after 32 years (p. 66)
White rice 25–30 years (p. 69)
Dry beans 20–30 years (p. 49)
Rolled oats up to ~30 years (p. 73)
Nonfat dry milk 3–5 years cool, as little as 3 months hot (p. 52)
Brown rice, whole-wheat flour, cornmeal, nuts, pearled barley not for long storage β€” oils go rancid; store whole grain and grind as needed (p. 32)

Rotate by eating it. Cooking one day a week only from storage rotates everything about every 7 years. Before throwing old food out, cook a sample β€” the stale smell on opening often fades. Old beans that won't soften: add β…› tsp baking soda per cup (BYU, p. 1).

βš–οΈ Setting and running a fair ration

Work out the ration (rule of thumb):

  1. Weigh everything, item by item.
  2. Count the days to the next harvest and add about 3 months of reserve.
  3. Daily ration per person = stock Γ· (people Γ— days), for each food.
  4. Turn it into calories (1 lb dry grain β‰ˆ 1,500 kcal) and compare with 2,100. The gap is what the garden, hunting, fishing, foraging and animals must make up.

Example (our arithmetic): 3 adult-equivalents, 13 months (395 days). 900 lb of grain Γ· (3 Γ— 395) β‰ˆ 0.76 lb per person per day β‰ˆ 1,100 kcal β€” half the need. Start the garden and the rabbits and chickens now.

Keep it fair (rule of thumb, except where cited):

If this goes wrong: one person losing weight faster β†’ check they really eat their share (children and old people often give theirs away). Stores shrinking faster than the log β†’ reweigh, check for rats and spoilage before suspecting people.

πŸ”₯ Cooking with little fuel

A fuel shortage is a nutrition problem: one refugee pellagra outbreak happened partly because people had no fuel to cook the beans they were given (WHO Pellagra, p. 29).

  1. Soak beans first (USU Dry Beans, p. 2).
  2. Crack or grind grain β€” meal cooks much faster than whole kernels.
  3. Boil briefly, let insulation finish it. Cook meal with at least 4 parts water to 1, boil briefly, then finish in a fireless cooker for 4–5 hours (Kearny, p. 89).
  4. Build a haybox: a box packed with hay, wool or blankets around a lidded pot (the parts; cut-away drawing). Beans and meat boil 20–25 minutes before going in (Practical Action, p. 5); old beans longer (USDA FB 771, p. 16).

Cut-away drawing of a fireless cooker: a lidded cooking pot sitting on a tray of ash and sand inside a basket packed with insulation, lined with cloth and plastic, with a stuffed cushion as the lid A haybox: insulation packed all around the pot, a tray under it and a thick cushion on top, so no heat escapes (Practical Action, p. 2).

🩺 Hunger diseases: spot them, prevent them

These come from eating the same few stored foods for months, and each is easy to prevent.

Disease Missing Signs Prevent with
Scurvy Vitamin C Tired, aching legs β†’ swollen bleeding gums, tiny bleeds at hair roots, swollen joints Sprouts, rose hips, berries, raw greens, potatoes, tablets
Beriberi Thiamine (B1) Numb, burning, weak legs; or swelling and heart failure Whole wheat, oats, beans, peas
Pellagra Niacin Dark, rough, sunburn-like rash on hands, neck, face (drawing); diarrhoea; depression or confusion Lime- or ash-treated corn, beans, peanuts, meat
Rickets Vitamin D Swollen wrists and rib ends ("beads"), bowed legs, late walking (drawing) Sun on bare skin, eggs, liver, fish, cod-liver oil
Goitre Iodine Swelling at the front of the neck (drawing); miscarriage; brain damage in babies Iodized salt, seafood, kelp

Scurvy (WHO Scurvy, pp. 15–17): 10 mg of vitamin C a day prevents and cures it; gums improve within about 2 weeks. Rose hips and many berries have over 300 mg per 100 g; cooking destroys it; breast milk covers a nursing baby (p. 33).

Sprouting for vitamin C (WHO Scurvy, pp. 35, 50; Kearny's sprouting drawing; photos):

  1. Soak whole (unsplit) beans, peas, lentils or wheat 12–21 hours.
  2. Drain and spread between damp cloths; keep them damp.
  3. Eat when shoots are ½–1 inch (30–48 hours) β€” the shoot holds the vitamin. Raw, or cooked under 30 minutes. Dried sprouts lose it.
  4. 1½–2 oz of dry seed per person per day is enough.

Three steps of sprouting: whole seeds soaking in a jar of water, seeds spread between two damp cloths, and seeds with shoots half an inch to an inch long beside a ruler Soak, spread between damp cloths, eat when the shoots are ½–1 inch (a diagram drawn for this guide).

Beriberi can appear within 2–3 months on white rice or white flour (WHO Thiamine, p. 14). Babies nursed by deficient mothers can die within hours, usually at 1–3 months old (p. 22). Don't over-wash rice or pour off its water. Strong tea, raw fermented fish and molds in damp food block thiamine (p. 17).

Pellagra comes from corn-heavy diets with untreated corn (WHO Pellagra, p. 13); one outbreak began 4 months after peanuts were dropped from a ration. If corn is a staple, nixtamalize it (FAO, p. 19; Food from Scratch) and eat beans or meat with it.

Rickets and our winter sun: 10–15 minutes of sun on a child's bare skin daily prevents it. Treatment: 5,000 IU vitamin D daily for 4–6 weeks, then 1,000 IU daily for 6 months, usually from fish-liver oil (WHO Management of Nutrition, p. 46). Rule of thumb: at 42Β° N the November–February sun is too weak to make vitamin D, and the valley is often cloudy β€” store cod-liver oil or vitamin D, and get children into the summer sun.

Iodine: adults need about 150 Β΅g a day (WHO, pp. 36–37), and 250 Β΅g when pregnant or nursing (WHO 2007). About Β½ teaspoon of US iodized salt gives roughly 150 Β΅g β€” you don't need more salt than that. The Pacific Northwest was historically part of the US "goitre belt" (rule of thumb) β€” store iodized salt sealed, dry and dark, and use fish and kelp from the coast.

🦴 Starvation and refeeding slowly

Recognize it (WHO Management of Nutrition, pp. 25–26; malnutrition; signs in children, mild to severe):

Refeed low and slow:

  1. Sudden big meals can cause fatal refeeding syndrome (rule of thumb).
  2. Starter formula (WHO F-75) for a severely malnourished child, used for the first days until appetite returns: 25 g dried skim milk + 70 g sugar + 35 g cereal flour + 27 g oil + water to 1 litre, boiled 5–7 minutes. Or 300 mL fresh cow's milk + 70 g sugar + 35 g flour + 17 g oil + water to 1 litre (WHO Severe Malnutrition, p. 21). After it cools, WHO adds 20 mL of mineral mix per litre (potassium and magnesium β€” "it must be added") and 140 mg vitamin mix or a multivitamin; recipes on p. 61.
  3. Small feeds every 2–3 hours, day and night (p. 22). No iron in the first week (p. 9).
  4. Adults: WHO aims for about 40 kcal per kg of body weight a day; once appetite returns, give ordinary food with added oil (WHO, p. 111). But if they've eaten almost nothing for a week or more, start lower β€” about 10–20 kcal per kg a day, building up over 4–7 days (UK NICE guidance). Feeding too much too fast can stop the heart (refeeding syndrome).
  5. Dehydrated and starving: don't give full-strength rehydration salts. One ORS packet in 2 litres plus 50 g sugar and 40 mL mineral mix (ReSoMal) (WHO Severe Malnutrition, p. 18).

Note: these manuals are from 1999–2000; WHO updated its guidance in 2013, including some drug doses. F-75 and ReSoMal are still used β€” leave the drugs to someone trained.

Breastfeeding first (WHO 2004, pp. 21–23):

If the milk has stopped or the mother is gone:

Babies 6–24 months:

🌿 Wild food around the valley

πŸ“· Not sure what it is? Photograph it with the plant and mushroom identifier (πŸ”§ Tools tab). It suggests names and flags poisonous groups, but it's often wrong: confirm every feature here before you eat or use anything.

What the Takelma ate here. The Takelma people lived along the middle Rogue and south toward the Illinois River (Sapir 1907, p. 3). Their staple was the "black acorn" (Sapir, p. 8; California black oak; photo), pounded, sifted, leached with hot water on clean sand and boiled as mush (Sapir, p. 9). Camas (photo) was pit-roasted on alder over hot stones, sometimes for days, then mashed into cakes for winter. Manzanita berries (flowers and berries) were pounded to flour with sugar-pine nuts; tarweed and sunflower-type seeds were parched and ground. They also ate madrone berries, pine nuts, salmon, steelhead, trout, crawfish and freshwater mussels.

Month by month (compiled from several books; dates shift 2–4 weeks with elevation and weather):

☠️ Foraging safety rules

πŸ“· Not sure what it is? Photograph it with the plant and mushroom identifier (πŸ”§ Tools tab). It suggests names and flags poisonous groups, but it's often wrong: confirm every feature here before you eat or use anything.

  1. Eat nothing not 100% identified β€” ideally confirmed by two people with a book.
  2. Skip the whole wild-carrot family (white umbrella-shaped flower heads β€” poison and water hemlock photos; wild carrot, poison hemlock). Western water hemlock grows along valley creeks and kills fast, by seizures (PNW 109, p. 5; chambered root and stem, p. 1; look-alikes side by side, pp. 3–4).
  3. Camas: dig only from a patch you watched bloom and marked plant by plant, only blue-flowered plants. Skip every white or cream-flowered plant β€” death camas is creamy-white and every part is poisonous (PNW 104, p. 2; WSU photos; Army drawing).
  4. Always leach acorns. Always cook elderberries; never eat their stems, leaves or green berries (OSU, p. 4; elderberry drawing).
  5. Never eat bracken fern β€” it holds a cancer-causing compound and an enzyme that destroys thiamine (WSU, p. 11; drawing).
  6. Cook anything from ponds (wapato, cattail, watercress) β€” parasites (rule of thumb).
  7. Throw out moldy, damp or discolored grain, and grass seed heads with black ergot spurs (USU, p. 66; rule of thumb; ergot photo).
  8. Lean meat alone starves you. Living on rabbit or lean venison without fat causes "rabbit starvation" β€” keep fat in the diet (render lard; rule of thumb).
  9. Try a new wild food in a small amount first, and take no more than a third of a patch (rule of thumb).

USDA photograph of a western water hemlock rootstalk split lengthwise, showing the stacked hollow chambers inside, with thick tubers and fine roots below Western water hemlock: the thick rootstalk is hollow, with cross-walls making chambers full of poisonous juice (AIB 415, p. 110).

USDA photograph of western water hemlock in flower: small white flowers in flat umbrella-like clusters on tall stems Water hemlock flowers: white umbrellas like the rest of the carrot family; leaf side veins run to the notches, not the tips (AIB 415, p. 109).

Two USDA photographs of death camas in bloom: clusters of small yellowish-white flowers on short stalks above grass-like leaves Death camas in bloom: yellowish-white flower clusters above grass-like leaves; skip every white or cream-flowered plant (AIB 415, p. 35).

If someone may be poisoned: death camas causes drooling, mouth numbness, vomiting, weakness, confusion and an irregular heartbeat 1–8 hours after eating (PNW 104, p. 2). Keep them warm, on their side if drowsy, watch their breathing, and keep a piece of the plant (rule of thumb). See the Field Care guide.
