The Dietary Reference Intakes (DRIs) are a set of nutrition recommendations for healthy people in the United States and Canada aimed at reducing the risk of chronic disease and promoting optimal health. The DRIs for most nutrients consist of four main values. The energy-containing nutrients use different standards, including two main values. Match the DRI that corresponds with the definition given below. (Note: Each DRI can be used only once.)

a. The nutrient intake level that is estimated to meet the requirements of half of the healthy individuals in a group
b. Determined after an EAR is established. If there is no EAR, it cannot be established
c. When this is established, it means that more research needs to be done to establish more evidence-based values
d. The highest nutrient intake level likely to pose no adverse health effects to a group of people
e. The value that is predicted to maintain energy balance healthy individuals
f. This considers the proportion of all energy sources in the diet that Will decrease risk of disease
