Storing a year of food sounds simple until you notice the three quiet traps. Enough energy to keep working. Enough variety and protein to stay healthy and sane — with no refrigerator to lean on. And enough micronutrients that a diet of rice and dal doesn't slowly make everyone ill. Miss any one and the plan looks full but fails.
So think of the store as three layers, not one shopping list.
Dry staples — grain, pulses, oil, sugar, salt — that keep for years in a drum and carry the bulk of the energy.
Preserved without refrigeration: tinned and retort meals, dried fish and dals, fermented and pickled things. Health, and something to look forward to.
The vitamins the staples miss. A thin, critical top layer — the difference between surviving and staying well.
