The categorisation of age groups used in the RDA’s are:
Infants- upto 12 months
Children-1 to 14 years
Adults – 14 years of age and above.
The RDAs and amount of nutrients present in foods are given in micrograms (mcg), milligrams(mg), or grams(g).
1,000 micrograms = 1 milligram
1,000 milligrams = 1 gram
