Recommended Dietary Intake refers to the amount of specific nutrients required in one day for good health.

This amount is set out in guides developed by Australia's National Health and Medical Research Council and the Commonwealth Department of Health and Aged Care. RDI tables are available from government bookshops. The amount your body needs to maintain a healthy weight, varies according to our age, sex, body size, amount of physical activity and whether you are pregnant or breastfeeding.

The RDIs do not help you understand what foods to eat to obtain specific nutrients. SO to help Australians meet these RDIs, the Commonwealth of Australia published The Australian Guide to Healthy Eating, which suggests how much food and what variety of foods to eat each day, according to your age and stage of life.
Formula For Life has merged this information with other leading health recommendations to create Recommended Intakes (RI) for foods and nutrients.

Recommended Intakes are important to ensure we eat enough of certain foods to keep us healthy. In some cases, too much of one type of food can cause an imbalance in our bodies which may lead to health problems. Recommended Intakes help you plan a measured and varied diet taking in the 5 food groups.
