Folate deficiency during pregnancy is a major risk factor for neural tube defects in the developing fetus. It is recommended for women of reproductive age to consume 400-800 micrograms of folic acid daily to prevent such defects. Megadoses of beta-carotene (A) are not recommended as they can be toxic in high amounts. Iodine deficiency (B) can also lead to developmental issues, but it is not specifically linked to neural tube defects. Excess alcohol consumption (D) can also have detrimental effects on fetal development, but it is not directly related to neural tube defects.
