Nutrition in Scarcity

Malnutrition in scarcity is not just about calories - micronutrient deficiencies cause blindness, immune collapse, and neurological damage long before starvation occurs. Understanding nutritional needs shapes every food-production and distribution decision.

Key Concepts

• —Macronutrient minimums: adults need roughly 2,000 kcal/day at rest, rising to 3,000+ with physical labor; fat and protein are the hardest to obtain from plant sources alone and require deliberate sourcing.
• —Protein quality and complementarity: grains are low in lysine; legumes are low in methionine; eating both together (rice and beans, corn and lentils) provides complete protein without animal products.
• —Critical micronutrients: vitamin A (orange/yellow vegetables, liver), vitamin C (fresh fruits, raw leafy greens), iodine (seafood, iodized salt), iron (dark leafy greens, blood, organ meat), and zinc (legumes, nuts, meat) are the most commonly deficient in crisis diets.
• —Children and pregnant women: caloric and protein needs per kilogram of body weight are highest in these groups; prioritize their access to diverse foods, especially animal protein and fresh vegetables, before other adults.
• —Fermentation as nutritional enhancement: fermenting grains and legumes (sourdough, injera, tempeh, fermented porridge) increases bioavailability of minerals, reduces anti-nutrients, and adds B vitamins through microbial activity.

Practical Guide

1. 1.Assess community food supply using a simple four-category inventory: carbohydrates (grains, roots), proteins (legumes, meat, eggs, fish), fats (oil, nuts, animal fat), and fresh produce; gaps in any category indicate deficiency risk.
2. 2.Diversify the garden toward nutrient density, not just calorie density: moringa, sweet potato leaves, amaranth, and stinging nettle are calorie-poor but extraordinarily rich in vitamins A, C, and iron.
3. 3.Establish a legume rotation in every garden plot to provide protein and nitrogen simultaneously; beans, lentils, and cowpeas are the most accessible and storable across climates.
4. 4.Identify and collect wild edibles seasonally: dandelion, wood sorrel, purslane, and nettles are nutrient-dense foods that grow without cultivation; catalog and map their locations around the settlement.
5. 5.Preserve vitamin C through fermentation rather than cooking: lacto-fermented vegetables (sauerkraut, kimchi-style preparations) retain and even increase vitamin C content versus heat processing.
6. 6.If animal products are available, prioritize organ meats (liver especially) and eggs for the highest micronutrient density per gram; distribute these to children and pregnant women first.
7. 7.Monitor nutritional status in children monthly using mid-upper arm circumference (MUAC): a circumference below 12.5 cm in children under five indicates acute malnutrition requiring immediate intervention.
