Health and Human Development - Using the RDIs
Using the RDIs
Tables of RDIs are intended for group use. They should not be seen as
individual requirements. It is reasonable to assume that an intake of at
least 70% of the RDI is an acceptable level of intake. When you calculate
the nutrient intake for an individual, present it on a bar graph compared
with the RDI for that individual, then draw a line across at the 70% level.
Compare the average nutrient intakes for this individual with the RDIs in
the Tables of Recommended Dietary Intakes for the age and sex of the person
you are studying. Which nutrients are well above the 100%? Do any fall
below 70% of the RDI? What does this mean? Do you know enough about the
functions of the nutrients to make informed comment?
Look more carefully at the nutrients. What happens in the body if there is
insufficient or an excess intake? Obviously an excess of water-soluble
vitamins from food (the B group and vitamin C) will not be a problem, as
the excess is excreted. It is difficult to take in an excess of vitamins
unless vitamin capsules are used. But what about low levels of vitamin
intake? Are the RDIs for the individual you are studying low each day or
did the intake on one day upset the average?
An intake of some nutrients well in excess of the RDI may not seem to have
much effect on an apparently healthy school age child, but the food intake
may be habit-forming. An intake in excess of the RDI over many years may
lead to health problems later in life for example; salt can lead to
hypertension, excess energy intakes to overweight or diabetes.

Some people do eat food(green vegetables) always with table-salt and high contents of energy food from cereals. what is going happy to their health?
It is reasonable to assume that an intake of at least 70% of the RDI is an acceptable level of intake
What happens in the body if there is insufficient or an excess intake
if taken RDIs for along time can be harmful to your health then what about the people who are above 45 yeas but still taken this RDIs or if that be the case can it be prescribe for them?
RDI TABLES can be used on an individual RDI intake or group use?
Is it possible to take in excess vitamins?

The Reference Daily Intake or Recommended Daily Intake (RDI) is the daily intake level of a nutrient that is considered to be sufficient to meet the requirements of 97–98% of healthy individuals in every demographic in the United States
