Question

1. nutrient levels set for nutrients which lack evidence to develop an ear or rda based on the observed intake of the nutrient in healthy individuals (1 point)

○ ear (estimated average requirement)
○ ai (adequate intake)
○ rda (recommended daily allowance)
○ dri (dietary reference intake)

1. organic substances made by plants or animals which aid the body in maintenance and proper functioning (1 point)

○ protein
○ fat
○ vitamin
○ mineral

1. substance which does not contain carbon (1 point)

○ macronutrient
○ organic substance
○ micronutrient
○ inorganic substance

1. consumption of a nutrient to the point the nutrient becomes poisonous and causes adverse effects (1 point)

○ nutrient deficiency
○ nutrient toxicity

Explanation:

1. For question 13: AI is defined as the nutrient intake level set when there is insufficient evidence to establish an EAR or RDA, based on observed intakes in healthy groups.
2. For question 14: Vitamins are organic compounds produced by plants/animals that support bodily maintenance and function, unlike proteins/fats (macronutrients for energy/structure) and minerals (inorganic).
3. For question 15: Inorganic substances are defined as those that do not contain carbon, distinguishing them from organic substances which do.
4. For question 16: Nutrient toxicity occurs when excessive intake of a nutrient leads to harmful, poisonous effects, as opposed to deficiency which is insufficient intake.

Answer:

1. B. AI (Adequate Intake)
2. C. Vitamin
3. D. Inorganic Substance
4. B. Nutrient Toxicity
