RDI stands for Recommended Dietary Intake, which is similar to the Recommended Dietary Allowance (RDA) but it is used in Australia and New Zealand. The RDI is the average daily intake level that is sufficient to meet the nutrient requirements of nearly all (97%–98%) healthy individuals in a specific life stage and gender group. The RDIs are set by the National Health and Medical Research Council (NHMRC) in Australia and the Ministry of Health in New Zealand.
Like RDA, RDIs are established for different nutrients, such as protein, vitamins and minerals, and they vary by age, gender, and life stage (e.g. pregnancy and lactation). The RDI is intended to provide a standard that can be used to plan and assess nutrient intake for individuals, but it is not a goal for individuals to strive for, rather a guide to help them make informed choices about the foods they eat and the supplements they take.
It’s important to note that the RDI is an average and may not be appropriate for people with special health needs or conditions. It’s always recommended to consult with a registered dietitian or a nutritionist for personalized advice and guidance on nutrient intake.
