TL;DR
Calories per pound is the critical metric for storage efficiency. Fats are twice as calorie-dense as carbohydrates or protein. A storage plan that's all rice and no fat is volume-efficient but energy-deficient. This table lets you calculate exactly how much of each food you need to store for your household's caloric requirements.

| Food | Cal/lb | Cal/cup | Protein/lb | Fat/lb | Shelf Life (sealed) | |------|--------|---------|-----------|--------|---------------------| | Vegetable oil | 3,500 | ~1,900 | 0g | 450g | 2-3 years | | Coconut oil | 3,500 | ~1,900 | 0g | 450g | 2-5 years | | Ghee (clarified butter) | 3,500 | ~1,900 | 0g | 450g | 1-2 yrs room temp | | Tallow/lard | 3,500 | ~1,900 | 0g | 450g | 1-3 years | | Pemmican | 2,000-2,500 | ~500 | 120-140g | 200-250g | 1-5 years | | Almonds (whole) | 2,600 | ~820 | 90g | 200g | 1-2 years | | Peanut butter | 2,500 | ~1,520 | 100g | 190g | 1-2 years | | Sunflower seeds | 2,600 | ~800 | 90g | 200g | 1 year | | Walnuts | 2,900 | ~770 | 65g | 270g | 1 year | | White sugar | 1,720 | ~770 | 0g | 0g | 30+ years | | Honey | 1,380 | ~1,030 | 0g | 0g | Indefinite | | Pasta (dry, white) | 1,700 | ~340 | 60g | 8g | 25+ years (Mylar) | | White rice (dry) | 1,650 | ~340 | 32g | 4g | 25-30 years (Mylar) | | Rolled oats | 1,720 | ~300 | 60g | 48g | 8-12 years (Mylar) | | All-purpose flour | 1,650 | ~450 | 44g | 8g | 10-15 years (Mylar) | | Cornmeal (degerminated) | 1,630 | ~440 | 40g | 12g | 5-10 years | | Lentils (dry) | 1,530 | ~680 | 110g | 5g | 25+ years | | Black beans (dry) | 1,540 | ~680 | 100g | 9g | 25+ years | | Kidney beans (dry) | 1,550 | ~670 | 105g | 5g | 25+ years | | Chickpeas (dry) | 1,640 | ~720 | 95g | 24g | 25+ years | | Peas (split, dry) | 1,590 | ~680 | 105g | 5g | 25+ years | | Powdered whole milk | 2,160 | ~640 | 110g | 90g | 2-5 years | | Powdered non-fat milk | 1,630 | ~435 | 160g | 5g | 5-10 years | | Dehydrated eggs | 2,260 | ~640 | 190g | 140g | 5-10 years | | Hardtack | 1,700 | — | 55g | 8g | 5+ years | | Jerky (lean beef) | 1,300 | — | 240g | 25g | 1-2 years (vacuum) | | Canned tuna (water pack) | 485 | — | 105g | 7g | 3-5 years | | Canned salmon | 615 | — | 110g | 16g | 3-5 years | | White sugar | 1,720 | ~770 | 0g | 0g | 30+ years |
Volume Comparison: Same Bucket, Different Calories
For a standard 5-gallon sealed bucket:
| Food | Approx. Weight | Total Calories | |------|---------------|----------------| | White rice | 33 lbs | ~54,000 | | Dried lentils | 33 lbs | ~50,000 | | Rolled oats | 22 lbs | ~38,000 | | White sugar | 38 lbs | ~65,000 | | Pasta | 25 lbs | ~42,000 | | Cornmeal | 30 lbs | ~49,000 |
Sugar provides the highest calories per bucket but zero nutritional value beyond energy. Rice and legumes balance calories, protein, and micronutrients.
Practical Storage Mix for Caloric Completeness
For a balanced high-calorie storage plan, target this mix per adult for a 90-day supply:
| Category | Quantity | Total Calories | Notes | |----------|---------|----------------|-------| | Grains (rice, oats, pasta, flour) | 50 lbs | ~82,000 | Primary calorie source | | Legumes (beans, lentils, peas) | 25 lbs | ~38,000 | Protein + carbs | | Fats and oils | 1 gallon | ~28,000 | Essential for fat-soluble vitamins | | Sweeteners (sugar, honey) | 10 lbs | ~17,000 | Energy, preservation, morale | | Protein supplements (canned meat, jerky, egg powder) | 10 lbs | ~9,000-15,000 | Amino acid completeness | | Total | ~96 lbs | ~174,000 calories | ~1,933 cal/day |
1,933 calories per day is a lean maintenance plan — adequate for moderately active individuals. Add more fats and grains to reach 2,200-2,500 for active adults.

Frequently Asked Questions
What is the most calorie-dense food for long-term storage?
By weight, fats and oils are the most calorie-dense at approximately 3,500 calories per pound. Pemmican is close at 2,000-2,500 per pound. Nut butters average 2,600 per pound. For practical storage, oils (3,500 cal/lb), nuts and nut butters (2,500-2,800 cal/lb), and hard cheeses or ghee offer the best calorie density. Pure carbohydrate staples like rice (1,650 cal/lb) are lower density but bulk up when cooked.
Why does caloric density matter for food storage?
Weight and volume are finite in any storage situation. A 5-gallon bucket of white sugar provides more calories (34,000) than the same bucket of oatmeal (18,000), but sugar is pure carbohydrates with no nutrition. Maximizing calorie density per unit of storage space while maintaining nutritional balance means you can store more total energy in less space — critical when storage is limited.
Which calorie-dense foods store longest?
White rice (25-30 years, Mylar-sealed), dried beans (25-30 years), honey (indefinite), salt (indefinite), white sugar (30+ years), ghee (1-2 years room temp, longer refrigerated), and hard liquor (indefinite, also has trade value). Fats generally have the shortest shelf life of calorie-dense foods — typically 1-5 years depending on type and storage conditions.
