Guidelines for healthy eating during pregnancy emphasize the importance of a balanced diet that includes a variety of nutrients. Pregnant individuals should consume adequate amounts of folic acid, iron, calcium, and protein to support fetal development. Focusing on whole foods like fruits, vegetables, whole grains, and lean proteins, while limiting processed foods and added sugars, is encouraged. Staying hydrated and avoiding certain foodborne pathogens is crucial for the health of both mother and baby, as is consulting healthcare professionals for personalized advice.
