The Budget Nutrition Arsenal
Not all cheap foods are equal. This is a ranked system for building a nutritious diet at minimum cost — organised into three tiers based on nutrient density per dollar, versatility, and shelf life.
How to use this list
Build your diet around Tier 1 foods as your daily base. Add Tier 2 foods for variety and completeness. Use Tier 3 strategically to fill specific gaps. Most families can meet 90%+ of their nutrient targets with the first two tiers alone.
TIER 1 Nutritional Pillars — Build your diet around these
These are the highest nutrient density per dollar foods available in Australian supermarkets. Each one is cheap, versatile, shelf-stable or freezable, and covers multiple nutrients.
Eggs (~$0.50–0.60 each)
The most complete whole food at any price point. Two eggs deliver approximately:
- 12g complete protein (all essential amino acids)
- Vitamin B12 (46% RDI), Vitamin A (16%), Vitamin D (12%), Choline (280 mg — 50–65% RDI)
- Selenium (54% RDI), Zinc (9%), Iron (9%)
Buy the 12-pack or larger — the per-egg price drops 20–30% vs smaller packs. Free-range and omega-3 enriched eggs deliver meaningfully more vitamin D and omega-3 for a small price premium.
Red Lentils (~$3–5/kg dry)
The best-value plant protein in Australia. Per 200g cooked serve:
- 18g protein, 16g fibre
- Folate (72% RDI), Iron (37% women's RDI), Zinc (18%)
- Magnesium (17%), Potassium (21%), B1 Thiamin (22%)
Red lentils cook in 15–20 minutes without soaking. They dissolve completely into soups and sauces, making them ideal for hidden nutrition in family cooking. Buy 1–2 kg bags for maximum savings.
Canned Sardines (~$1.50–2.50/tin)
One of the most underrated foods in Australia. A single 95g tin delivers:
- 23g protein
- Omega-3 (DHA + EPA): ~1,000–1,500 mg
- Vitamin D: ~250 IU (42% RDI) — one of the few affordable food sources
- Calcium: ~350 mg (35% RDI) from softened bones
- Vitamin B12: ~150% RDI
- Selenium: ~70% RDI
Buy in bulk when on special — shelf life of 2–3 years. Sardines in olive oil offer better omega-3 preservation than brine or tomato sauce.
Rolled Oats (~$2–4/kg)
The cheapest complete breakfast and the most versatile grain. Per 80g dry serve:
- 11g protein, 8g fibre (including beta-glucan — clinically proven to lower LDL cholesterol)
- Manganese (191% RDI), Phosphorus (41%), Magnesium (13%), Zinc (16%)
- B1 Thiamin (51%), Iron (22%), Selenium (22%)
Much cheaper than any packaged cereal with a fraction of the added sugar. Buy the 1–2 kg bags. Traditional rolled oats have a lower glycaemic index than quick oats.
Frozen Spinach / Kale (~$2–3/500g)
Nutritionally superior to fresh for cooking purposes and far cheaper. Per 1 cup cooked (180g):
- Vitamin K: 250%+ RDI (vital for blood clotting and bone health)
- Vitamin A: 47% RDI (as beta-carotene)
- Folate: 33% RDI, Iron: 36% women's RDI, Magnesium: 37%
- Vitamin C: 29% RDI, Calcium: 24%
A 500g bag costs ~$2–3 and contains the equivalent of 3–4 fresh bunches. Add to anything — soups, pasta sauce, curries, eggs. Almost impossible to detect when blended into sauces.
Chicken (whole or thighs) (~$4–7 whole / ~$6–8/kg thighs)
The most affordable complete animal protein. A whole chicken typically yields 4–5 meals and the carcass makes 2–3 litres of bone broth.
- Per 100g cooked thigh: 26g protein, Zinc (20%), Selenium (35%), B3 Niacin (50%), B6 (30%), B12 (10%)
- Thighs are 40–50% cheaper per kg than breast fillets with superior fat content (monosaturated)
TIER 2 Essential Supporting Foods
These foods provide variety, specific nutrients, and build complete meals around your Tier 1 base.
| Food | Approx. cost | Primary nutritional value |
|---|---|---|

| Canned tomatoes | ~$0.80–1.20/tin | Lycopene (antioxidant, bioavailable when cooked), vitamin C, folate |
| Carrots | ~$1.50/kg | Beta-carotene (vitamin A — 74% RDI per ½ cup cooked), fibre, potassium |
| Full-cream milk | ~$1.50–2/L | Calcium (300mg/cup), iodine, protein, B12, B2 |
| Brown rice | ~$2–3/kg | Fibre, manganese, B vitamins, magnesium — more nutritious than white |
| Canned chickpeas | ~$1.20/400g tin | Plant protein, folate, iron, zinc, fibre |
| Pumpkin seeds | ~$8–12/kg | Magnesium (38% RDI/30g), zinc (16%), omega-3 ALA, iron |

| Bananas | ~$2–3/kg | Potassium, B6, magnesium, quick energy, prebiotic fibre |
| Cabbage | ~$1–2/head | Vitamin C (54% RDI/cup), vitamin K, folate — one of the cheapest vegetables |

TIER 3 Strategic Gap-Fillers
These foods fill specific nutritional holes cost-effectively. Use them targeted rather than as daily staples.
| Food | Gap it fills | Notes |
|---|---|---|
| Canned salmon (~$2–3/tin) | Vitamin D, omega-3, calcium | Higher vitamin D than sardines; useful variety |
| Peanut butter (~$4–5/kg) | Healthy fats, protein, niacin, magnesium | Check for no-added-sugar varieties; very satiating |
| Fortified breakfast cereal | Iron, B vitamins, folate | Check label — choose low sugar, high iron (>25% RDI/serve) |
| Iodised salt | Iodine | Critical — regular salt and sea salt are NOT iodised. Switch to iodised. |
| Frozen berries (~$4–6/kg) | Antioxidants, vitamin C, fibre | Significantly cheaper than fresh; nutritionally equivalent |
| Dark chocolate 70%+ (~$3–4/100g) | Iron (19% RDI/30g), magnesium, antioxidants | Small amounts go a long way; avoid milk chocolate |
| Canned tuna (~$1.50–2/tin) | Protein, omega-3, selenium, B12 | Good variety to sardines; lower vitamin D but more popular with kids |
| Greek yoghurt (~$5–7/kg) | Calcium, probiotics, protein, B12 | Probiotics support gut microbiome; full-fat is more satiating |
| Walnuts (~$15–20/kg) | Omega-3 ALA, brain-protective polyphenols | Most expensive item here but a small daily serve (30g) is effective |
| Beef/chicken liver (~$3–6/kg) | B12 (2,917% RDI/100g), vitamin A, folate, iron, riboflavin | Limit to 1–2×/week. Exceptional nutrition but very high vitamin A — avoid in pregnancy first trimester. |
