  • The recommended daily energy intake for an adult female sedentary worker is 1900 kcal.
  • The recommended daily protein intake for an adult female sedentary worker is 55 gm.
  • Additional daily energy for pregnant women is 60,000 kcal on average.
  • Extra calories required by a lactating mother during the first six months is 600 kcal on average.
  • Additional daily protein requirement in pregnancy is 23 gm.
  • On average, a healthy adult woman gains 12 kg during pregnancy (6.5 kg in poor Indian women).

Other Information

  • Requirement of iron and folic acid is more during pregnancy than lactation
  • Requirement of calcium and pyridoxine is equal during pregnancy and lactation.
  • Requirement of other nutrients is less during pregnancy than lactation.
  • For calculating RDA of a nutrient, 2 standard deviations are not added for energy.
  • Recommended Dietary Allowance (RDA) is a level of intake that covers the requirement of 97.5% of the population
  • RDA is the safe level of intake and not used for energy, because excess energy is not desirable.
  • Reference Indian Man, 18-29 years, 60 kg, 1.73 m and BMI 20.3
  • Reference Indian Woman 18-29 years, 55 kg, 1.61 m and BMI 21.2

    • The recommended daily allowance of protein is 60 g/day
  • The recommended daily energy intake of an adult female with heavy work is 2900 kcal.
  • Consumption Unit Coefficients (CUC) for adolescents is 1.0.
  • Daily protein requirement for an adult is 0.7 g/kg (egg protein) or 1.0 g/kg (mixed vegetable protein). More recent guidelines suggest 0.83 g/kg/day.
  • For Indian adults, the ICMR recommends 1.0 g protein/kg of body weight.
