Group B vitamins (folic acid and vitamin B12) and zinc play a very important role in the development of oocyte, since zinc is required in synthesis of DNA and cellular division. Similarly, foods rich in iron are also rich in folic acid.
Studies demonstrate that conception rates increase in women, if daily Vitamin D needs are met.
Foods that contain vitamins with positive effects on oocyte development include green-leaved vegetables, liver, cumin, egg, banana, corn, date palm, almond, fish oil, fish, broccoli, potato, dried grape, fig, whole-meat paste, red meat, poultries, okra, orange juice, black eyed bean, lentil, sunflower seed, pumpkin seed, grape, ananas juice, chickpea and russian turnip.
