Essentials of Normal Pregnancy
Pregnancy is physiologically and nutritionally a highly demanding period. A pregnant woman prepares herself to meet the nutritional demands by increasing her own body fat deposits during pregnancy. The fetus inside the uterus of mother is like a parasite (i.e., it takes several nutrients that it requires from the mother, regardless of whether she has enough of them or not). However, it has been observed that women's diets among poor socio-economic groups during pre-pregnant, pregnant, and lactating periods are essentially similar. Consequently, widespread maternal malnutrition results in a high prevalence of infants with low birth weight and a very high maternal mortality rate. Extra diet is needed to improve the birth weight and increase deposits of fat in the maternal body. Adequate intake of nutritious diet is reflected in optimal weight gain of 10 to 12 kg during pregnancy. Some micronutrients are especially required in extra amounts to meet the physiological needs of this period. Hence, good nutrition must be ensured for optimum growth and development of children, adolescents, and women.
