Dietary Reference Intakes (DRI)

• Purpose: Recommended nutrient intakes for individuals.
• Units: RDA (Recommended Dietary Allowance) or AI (Adequate Intake).
  • Bolded: RDA, meeting needs of 97%-98% of the population.
  • Non-bolded: AI, based on best scientific estimates.
• Nutrients Displayed: Some in milligrams, others in micrograms.
  • Micrograms are smaller than milligrams.

Structure of Tables

• Categories: Segmented by life stages and gender.
  • Infants, children, adults.
  • Specific requirements for pregnant or lactating individuals.
• Example: 21-year-old male's Vitamin C recommendation is 90 mg/day (RDA).

Types of Tables

• Vitamins: Lists RDAs and AIs for various vitamins.
• Minerals/Elements: Similar tables available for minerals.
• Macronutrients: Contains acceptable macronutrient distribution ranges.

Upper Levels (UL)

• Purpose: Indicates safe upper intake levels to prevent toxicity.
