NUTR1023 Module Three: Diet and Physical Activity Guidelines
Dietary Guidelines
• Developed to provide the foods and diet patterns that achieve an optimal intake of
essential nutrients in our diets and also protect in the long term from the development of
chronic disease
• Dietary guidelines have five key aims
1. achieve and maintain a healthy weight, be physically active and choose amounts of
nutritious foods and drinks to meet energy needs
2. enjoy a wide variety of nutritious foods from the five food groups everyday
-vegetables including legumes and beans
-fruit
-grain
-lean meats and poultry
-calcium based foods
3. Limit intake of foods containing saturated fat, added salt, added sugars and alcohol
4. encourage, support and promote breastfeeding
5. care for your food; prepare and store it safely
• The statements are rather broad and provide no information about what kind of portions
of foods should be eaten
Nutrient Reference Values
• Provide specific values about how much of a specific nutrient should be consumed
• (Estimated Average Requirement): a daily nutrient estimated to meet the requirements
of the half the healthy individuals in a particular life stage and gender group
• Recommended Dietary Intake (RDI): the average daily dietary intake level that is
sufficient to meet the nutrient requirements of nearly all (97-98%) healthy individuals
in a particular life stage and gender group
• Adequate Intake (AI): used when an RDI cannot be determined. The average daily
nutrient intake level based on observed or experimentally-determined approximations of
estimates of nutrient intake by a group/s of apparently healthy people that are assumed
to be adequate
• Estimated Energy Requirement (EER) the average dietary energy intake that is
predicted to maintain energy balance in a healthy adult defined ages, gender, weight,
height, and physical activity, consistent with good health. In children and pregnant and
lactating women, the EER is taken to include the needs associated with the deposition
of tissues or the secretion of milk at rates consistent with goo health
• Upper Level of Intake (UPI): the highest average daily nutrient level likely to pose no
adverse health effects to almost all individuals in the general population. As intake
increases about the Upper Level, the potential risk of adverse health effects increases
• Acceptable Macronutrient Distribution Range (AMDR) an estimate of the range of
intake for each macronutrient for individuals (expressed as percent contribution to
energy) which would allow for an adequate intake of all the other nutrients whilst
maximising general health outcome
• Suggest Dietary Target (SDT): a daily average intake from food and beverages for
certain nutrients that mat may help in prevention of chronic disease
