The 1st-month pregnancy diet is crucial for the development of a healthy baby. However, unfortunately, women often find out they are pregnant only after having missed a period, and by the time they realize this, they have mostly crossed the first month.

So, it would help if you start a healthy and pregnancy-safe diet as soon as you begin planning to conceive and have a family. This will help ensure a safe pregnancy.

Read on as we tell you about some nutritious, healthy foods you should include in your diet during the first month and the foods you should avoid.

Foods To Include In The First Month Of Pregnancy

Foods from the following groups must be a part of your diet in the first month of pregnancy.

  • Include foods such as green leafy vegetables, legumes, avocado, lentils, fortified bread, orange juice, beans, and cereals that are rich in folic acid (1). Folic acid is an essential nutrient for the brain and spinal development of the fetus. It helps in blood formation during pregnancy and preventing neural tube defects in the baby.
  • Milk and milk products such as yogurt and cheese are a good source of calcium. Calcium is essential for fetal heart and nerve functions and helps in developing strong bone, teeth, and muscles.
  • Fruits and vegetables including the yellow and red ones, cabbage, broccoli, strawberries, citrus, and Brussels sprouts are rich in vitamin C, which is essential for the baby’s teeth and bone development.
  • Add fiber-rich foods like oats, whole grain bread, legumes, fruits, and vegetables in your diet for relieving constipation and regularizing the bowel movement.
  • Lean meat is a good source of iron and protein, which helps in making hemoglobin. Also, it is essential to meet the blood supply demand by the fetus.
  • Seeds and nuts are protein-rich foods that help in developing the fetal tissues and repairing breast and uterine muscles. They also aid in meeting the blood requirements during pregnancy.

  • Iodized salt is the primary source of iodine, which is essential for the baby’s nervous system and brain development.
  • Fortified bread and cereals are rich sources of fiber and B vitamins, which are necessary for the fetal brain and nerve development.
