Pregnant women are either too worried about gaining a lot of weight or else they feel they are underweight. One has to understand that the quality of the food is what plays a significant role, rather than the quantity. Just because you are pregnant you do not need to consume extra calories until your second trimester. "The caloric requirement of pregnancy increases by only about 300 calories," says Lisa Zaffner, nutritionist and director of operations at Healing Quest Center in Chicago. So, ‘eating smart’ should be your mantra. Have foods that are rich in vitamins, minerals and nutrients.
