These days most supermarkets fruit and vegetables are grown commercially, which means that they lack in many the nutrients that they should have. On top of that many women are on the go, and eat more instant meals; they might even skip meals and eat on the run. When you are pregnant, it is not only you that might be lacking in vital nutrients but a new life growing inside of you too. The growing foetus needs a lot of vitamins, minerals and good fats to develop and grow. A lack of nutrition can result in birth defects in the baby and cause pregnant women to become run down and prone to the common cold.
