Final answer:
The Adequate Intake (AI) is the average daily amount of a nutrient that appears sufficient to maintain health when the Recommended Dietary Allowance (RDA) cannot be determined due to a lack of sufficient evidence.
Step-by-step explanation:
The Adequate Intake (AI) is the average daily amount of a nutrient that appears sufficient to maintain health when the Recommended Dietary Allowance (RDA) cannot be determined due to a lack of sufficient evidence. The AI is set based on available scientific data and is used as a reference for nutrient intake recommendations.
For example, if there is not enough evidence to establish an RDA for a particular nutrient, but research suggests that a certain amount is needed to prevent deficiency and maintain health, that amount becomes the AI for that nutrient.
It's important to note that the AI may be revised as more research becomes available, allowing for a more accurate determination of the nutrient's requirements.
