Micronutrient deficiency during pregnancy could adversely affect the baby in the following ways (4):

  • Low Zinc levels can cause fetal growth retardation and congenital abnormalities.
  • A deficiency of folate can cause neural tube defects in the infant.

Prevention

Having a balanced diet can help you enjoy a safe pregnancy. Consume a lot of fruits and vegetables to gain vitamins, minerals and fiber. Include healthy protein sources like fish, eggs, pulses, beans, and poultry in your diet. Also, add starchy foods like cornmeal, pasta, noodles, bread, and potatoes to meet your increased carbohydrate requirement (5).

Pregnancy increases the nutritional demands of the body to support fetal growth. Excess vomiting, underlying conditions affecting eating and digestion, or socio-economic factors may be responsible for malnutrition during pregnancy. Consuming excess junk food may also lead to malnutrition, if it takes the place of nutrient-dense food. Congenital abnormalities such as neural tube defects, growth retardation, premature birth, and miscarriage may be attributed to specific nutritional deficiencies caused by malnutrition. Most of the issues may be prevented with dietary and lifestyle changes. However, you should consult a doctor to identify the required nutrients and supplements to avoid deficiencies.
