Teenagers often have very poor diets, according to KidsHealth.org. During pregnancy, you'll need to adjust your diet to meet the nutritional needs of your changing body, and your growing baby. Consider meeting with your physician or nutrition professional to create a healthy eating plan. Skipping foods that offer little to no nutritional value, such as soda and candy, and replacing them with healthy alternatives may help you have a healthier pregnancy and a healthier baby.
Fruits and Vegetables
Five servings of fruits and vegetables per day is appropriate during pregnancy, according to the Missouri Department of Health and Human Services. Vegetables contain vitamins, including vitamin A and vitamin D which are essential for fetal development. Consider vegetables like broccoli, green peppers, leafy greens, Brussels sprouts and cauliflower for a boost of Vitamin C. Carrots, leafy greens, pumpkin, sweet potato and tomatoes are good sources of Vitamin D. Beneficial fruits include citrus fruits, apricots, cantaloupe and strawberries.
Fruits or vegetables may be eaten raw or prepared. Be careful of commercially prepared or canned fruits or vegetables that may contain added fats and sugars. Sliced vegetables make a quick snack while cubed fruit is a healthy replacement for sweets.
Dairy Products
Milk and milk-based products are good sources of calcium and vitamin D, needed for bone growth. Dairy products are also rich in protein which is essential for muscle and tissue development. Choose 3 to 4 servings of low-fat milk, cottage cheese, sliced cheese, yogurt, cream cheese or low-fat ice cream daily.
Whole Grain
Foods made with whole grain supply B vitamins, carbohydrates and fiber. Choose foods made with whole grain such as whole wheat, over products made with processed white flour for better nutrition. Foods such as whole grain bread, pastas, crackers or pancakes are good choices. You may also enjoy brown or wild rice which are also good nutritional choices. The Missouri Department of Health and Human Services recommends six servings of grains per day.
Iron-rich Foods
Iron is important for healthy blood development. "The Handbook of Nutrition and Pregnancy" states that pregnant teens should consume iron from animal sources if possible, such as red meat, poultry or fish as iron from these sources are better absorbed in the body. You may choose iron-fortified breads, cereals or drinks.
