The easiest way to make sure you're getting all the calories you need is to eat five or six small meals a day. This is especially helpful if nausea, food aversions, heartburn or indigestion make eating a chore. Try to eat at least every four hours - even if you're not hungry, your developing baby needs regular sustenance.
Make sure you're consuming at least five portions of fruit and veg each day. Dark green vegetables, such as spinach and broccoli, are packed with essential vitamins and minerals, including folate which helps your baby's development. Dried fruit is easy to carry with you and is also a great source of fibre, calcium and iron. Start taking a prenatal vitamin-mineral supplement and make sure it contains 600 to 800 micrograms of folic acid. You may need to take iron or calcium supplements later on in your pregnancy if your GP recommends it.
While you should watch what you eat, you shouldn't diet while pregnant. Many diet plans are more than likely to leave your body low on iron, folic acid, and other important vitamins and minerals. Weight gain is a positive sign of a healthy pregnancy, although the timing of the weight gain is just as important as the total number of pounds. The least amount of weight gain should occur during the first trimester, about two to five pounds in total. You should slowly and steadily gain ending with the greatest number of pounds, approximately a pound a week, in the third trimester.
