Nutrition & Supplements for a Healthy Pregnancy

Good nutrition during pregnancy supports the healthy development of the baby and maintains the mother’s physical and emotional well-being. The first trimester establishes foundations for fetal organ growth, while later trimesters require additional nutrients for brain, bone, and blood development.

1. Essential Nutrients

– Folic Acid: Prevents neural tube defects; recommended 400–800 mcg daily.

– Iron: Supports increased blood volume; prevents anemia.

– Calcium: Helps bone and teeth development.

– Vitamin D: Supports bone health and immune function.

– Iodine: Crucial for fetal brain and thyroid development.

– Omega‑3 (DHA): Supports brain and eye development.

2. Foods to Prioritise

A balanced pregnancy diet includes:

– Leafy greens, fruits, whole grains

– Eggs, dairy, legumes, lean meat

– Nuts, seeds, and healthy fats

– Plenty of water for hydration

3. Foods to Avoid

Avoid foods that carry infection or toxicity risks:

– Unpasteurised dairy

– Raw or undercooked meat and eggs

– High‑mercury fish (shark, swordfish, king mackerel)

– Alcohol

– Excess caffeine (limit to 200 mg/day)

4. Managing Food Aversions

Most women experience food aversions due to hormonal changes. Eating small frequent meals, choosing tolerated foods, and ensuring hydration helps maintain nutrition.

5. Supplements

Supplements fill nutritional gaps when diet alone is insufficient. These should be taken under medical guidance to avoid excessive intake.

Doctor Recommendations:

– WHO: All pregnant women should receive daily folic acid and iron supplementation.

– NHS: Vitamin D supplementation is recommended throughout pregnancy.

– ACOG: Omega‑3 DHA intake supports fetal neurological development.
