Visualize Dietary Guidelines for Different Ages

Dietary Reference Intakes (DRIs) establish nutrition targets based on a person's age and gender. With the Wolfram Knowledgebase's data on nutrition, these dietary guidelines can be visualized with ease.

Find a nutrient's Daily Value (DV) as a function of age.

Determine the Daily Value recommendation at a particular age.

Repeat for the Tolerable Upper Intake (TUL).

Create a function to visualize the age dependence of DRIs, including the Estimated Average Requirement (EAR), Adequate Intake (AI) and Recommended Dietary Allowance (RDA).

Repeat for Vitamin B₁₂.

Look specifically at zinc's DRIs for children under five years.
