Importance of Nutrition During Pregnancy
Proper nutrition during pregnancy ensures that both mother and baby receive the energy and nutrients required for healthy development. Nutrient deficiencies can lead to complications such as low birth weight, developmental delays, and maternal health issues. By planning your diet carefully, you can reduce risks and provide your baby with a strong start in life.
Did You Know? Iron deficiency is one of the most common nutrient deficiencies during pregnancy, affecting up to 40% of pregnant women worldwide.
Energy Requirements
During pregnancy, your body needs extra calories to support the growing baby and maternal tissues. Generally, an additional 300–500 calories per day are recommended in the second and third trimesters. However, quality matters more than quantity—nutrient-dense foods are preferred over empty calories.
