Final answer:
The Essential Nutrient Index (ENI) is not a category of the Dietary Reference Intake (DRI); the DRI categories include Recommended Dietary Allowance (RDA), Adequate Intake (AI), and Tolerable Upper Intake Level (UL). The correct option is d) Essential Nutrient Index (ENI).
Step-by-step explanation:
The category that is not a part of the Dietary Reference Intake (DRI) is d) Essential Nutrient Index (ENI). The DRIs include a) Recommended Dietary Allowance (RDA), which provides guidelines for the daily intake of nutrients to meet the needs of most healthy individuals.
There is also b) Adequate Intake (AI), which is used when there is not enough evidence to establish an RDA and is based on observed or experimentally determined estimates of nutrient intake by a group of healthy people. The c) Tolerable Upper Intake Level (UL), sometimes known as just the "upper limit," refers to the maximum daily intake that is unlikely to cause adverse health effects.
The category that is not a part of the Dietary Reference Intake (DRI) is the Essential Nutrient Index (ENI). The correct option is d) Essential Nutrient Index (ENI).
The correct option is d) Essential Nutrient Index (ENI).
