  1. * The median daily phytate intake and median molar ratio of phytate to calcium, iron, zinc and phytate × calcium:zinc are presented.
  2. † The reference man is defined as males aged 18 years, undertaking light physical activity, whose daily reference energy intake is 2400 kcal [21]. Therefore, daily nutrient intakes were adjusted by daily nutrient intake times 2400 kcal divided by her recommended nutrient intakes (RNIs) of energy. The equation is expressed as dietary intakes × 2400/2300 (Pregnant women RNI of energy [21]).
  3. ‡ Calculated as: 1 μgRE Vitamin A = 1 μg retinol+ 1/6 μg carotene.
  4. Legend: Mean daily nutrient intakes and molar ratios of dietary phytate: calcium, iron and zinc, and phytate × calcium: zinc pregnant women in rural Shaanxi China 2004 compared to the 2002 Chinese National Nutrition and Health Survey (2002 NNHS) [12, 15].
