KIDSEating healthy foods in pregnancy improves your baby's health
Is this true? Make your call, then see what the science says.
Short answer: Yes. The evidence supports this.
Australian guidance and several reviews say a healthy, varied diet in pregnancy supports a baby's health and development. Much of the research is observational, so it shows a link rather than proof for each food.
AI-generated summary of the research cited · not reviewed by a medical professional · checked 13 October 2026 · How we checkWhat the research found
Australian health guidance says good nutrition during pregnancy helps keep you and your developing baby healthy. It also says there is substantial evidence that what you eat can have a lasting effect on your child's health later in life. A 2022 review describes nutrition in pregnant mothers as a long-known determinant of fetal and maternal outcomes. A 2019 review calls nutrition from conception to age two critical for healthy development.
A 2024 systematic review of 14 studies found fewer low birth weight and preterm babies when a dietitian was involved in prenatal care. This shows an association. It does not isolate the effect of food itself, and the review said more research is needed on several other outcomes.
Food is not a cure-all. A 2022 review found that maternal dietary restrictions during pregnancy and breastfeeding do not appear to help prevent or treat atopic dermatitis (eczema) in children.
What it doesn’t mean
- Healthy eating does not guarantee a healthy baby. Many things affect a baby's health, and most diet research shows links rather than proof.
- Food safety matters as much as healthy choices. Women who are pregnant are advised not to drink alcohol, to limit fish high in mercury, and to avoid higher-risk foods that may contain Listeria. If you are overweight, pregnancy is not the time to start dieting.
- Talk to your GP, midwife or a dietitian before taking supplements. Folic acid and iodine supplements are recommended during pregnancy, and your needs may differ.
