Eating in the First Trimester

An expectant mother's relationship with food alters drastically during the first trimester. An awareness of the developing systems within the fetus and their susceptibility to birth defects linked to poor diet during pregnancy are only some of the reasons why mothers question the healthful qualities of every bite entering their mouths.
Morning sickness is also affected by diet and poor eating habits. Regularly eating foods that contribute to steady blood sugar levels can keep nausea in check.
One kernel of lesser known first trimester dietary wisdom is that moms-to-be should not increase their portion sizes at all. The body's caloric needs are not changed during those first few weeks of pregnancy.
