DRI is the general term for a set of reference values used to plan and assess nutrient intakes of healthy people. These values, which vary by age and gender, include: Recommended Dietary Allowance (RDA): average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%-98%) healthy people.
How much do we need each day. The Australian Dietary Guidelines inform people of different ages, life stages and gender, the minimum number of serves from each food group they need to eat each day, to make sure they get the full amount of nutrients their body needs. Most people who want to lose weight should stick to the minimum number of serves. However, people in their healthy weight range, who are taller than average or more physically active, may find they need extra serves from the five food groups.
