Eating walnut during pregnancy is of great value for both, the fetus and for the mother. The omega 3 fatty acid which is present in walnut can reduce the chance of skin disease, such as eczema in the child. It also prevents developing asthma in the child. It also helps the fetus to develop a healthy nervous system.
Walnut also reduces the chance of developing pregnancy related hypertension. Woman, who has history of post partum depression, should eat walnut regularly during pregnancy.
