🧠 Why Diet Matters for Fertility
Numerous studies confirm that nutrition plays a direct role in fertility — for both men and women. Eating nutrient-dense foods:
- Supports hormonal balance
- Promotes regular ovulation
- Enhances egg quality and sperm health
- Reduces inflammation and regulates insulin
✅ According to the Harvard School of Public Health, diets rich in plant-based protein, whole grains, and healthy fats are linked to higher fertility rates.
🥇 1. Leafy Greens (Spinach, Kale, Swiss Chard)
Why it helps:
Rich in folate, iron, and antioxidants, leafy greens help support healthy ovulation and prevent neural tube defects early in pregnancy.
Nutrients:
- Folate (B9)
- Iron
- Magnesium
- Vitamin C
Add to smoothies, salads, or sautéed side dishes.
🥚 2. Eggs
Why it helps:
Eggs, especially the yolks, are a powerhouse of choline, omega-3s, and vitamin D — all crucial for reproductive health and early fetal development .
Nutrients:
- Choline
- Vitamin D
- Protein
- Omega-3 fatty acids (esp. in pasture-raised eggs)
Ideal for breakfast with avocado and whole-grain toast.
🥜 3. Nuts & Seeds (Almonds, Walnuts, Flax, Chia)
Why it helps:
Nuts and seeds contain healthy fats, plant-based protein, and zinc, supporting hormone regulation and sperm motility.

- Selenium
- Vitamin E
Sprinkle on yogurt or blend into smoothies for a crunchy boost.
🐟 4. Fatty Fish (Salmon, Sardines, Mackerel)
