Nutrient Intake Calculator – Iron
This nutrient intake calculator will help to estimate dietary intake of iron and whether your regular daily diet can meet recommended dietary reference intakes (DRIs).
Functions and benefits of iron
Iron is an important mineral for oxygen transportation to body tissues, normal production of various cells and hormones as well as healthy brain development and growth in children1. Symptoms of iron-deficiency anemia include dizziness, poor appetite and weakened immune system2.
A study in 2017 found the mean intake of iron in preschool children aged 30-60 months was significantly lower than the adequate intake (AI) recommended by the Chinese Nutrition Society (CNS)3. On the other hand, the First Hong Kong Total Diet Study published in 2014 showed the dietary intake of iron of more than 80% male adults and more than 90% female adults was below the recommended nutrient intake (RNI) by CNS4.
