Pregnancy Nutrition on a Budget

Your nutrient needs increase significantly during pregnancy — but eating well for two doesn't mean spending double. Here's what matters most and the cheapest foods to get it.

The most critical nutrients in pregnancy

Folate (Folic acid)

Folate is essential in the first trimester to prevent neural tube defects. The recommended intake jumps to 600 mcg/day during pregnancy (up from 400 mcg). Best budget sources:

• Red lentils — 1 cup cooked delivers ~360 mcg folate (~60% of daily need)
• Frozen spinach — 1 cup cooked ~263 mcg
• Canned chickpeas — 1 cup ~282 mcg
• Broccoli — 1 cup cooked ~168 mcg

Most midwives and GPs recommend a folate supplement (400–800 mcg/day) from at least one month before conception through the first trimester.

Iron

Iron needs nearly double in pregnancy to 27 mg/day (up from 18 mg for women of reproductive age). Iron supports the expanding blood volume and foetal development.

• Kangaroo mince — ~7 mg per 100g (one of the richest iron foods available)
• Beef mince (lean) — ~3 mg per 100g
• Canned lentils — ~3.3 mg per cup
• Pair plant iron sources with vitamin C (capsicum, citrus) to double absorption

Iodine

Iodine is critical for foetal brain and thyroid development. Australian soils are iodine-poor, making dietary iodine harder to get. Target: 220 mcg/day.

• Use iodised salt (not sea salt or Himalayan salt, which are low in iodine)
• Dairy milk — ~50 mcg per cup
• Canned tuna or salmon — ~35 mcg per 100g
• Eggs — ~27 mcg each

Many pregnancy multivitamins include 150 mcg iodine — check your supplement label.

DHA (Omega-3)

DHA supports foetal brain and eye development. Aim for at least 200 mg/day.

• Canned sardines — ~1000 mg omega-3 per can (excellent)
• Canned salmon — ~1500 mg per 100g
• Eggs (omega-3 enriched) — ~300 mg each

Calcium

The growing baby draws calcium from your bones if your intake is low. Target: 1000 mg/day.

• Full-cream milk — ~300 mg per cup (cheapest source)
• Canned sardines with bones — ~200 mg per 95g can
• Hard cheese — ~200–300 mg per 30g serve
• Frozen broccoli — ~62 mg per cup

Foods to limit or avoid in pregnancy

• High-mercury fish: shark (flake), swordfish, marlin, orange roughy — limit to once a fortnight
• Liver and pâté: very high in vitamin A (retinol) — can cause birth defects in excess
• Unpasteurised dairy, soft cheeses (brie, camembert, feta unless cooked), deli meats — listeria risk
• Raw or undercooked eggs, meat and seafood
• Alcohol — no safe amount has been established
• Caffeine — limit to 200 mg/day (about 2 instant coffees)
