# Vitamins, minerals and water

Lesson 3 of 16 in **Eat well, simply** (NUTR 101), unit "What's in your food". An open lesson from Maestro College.

## What the learner will be able to do
- Explain the difference between vitamins and minerals and give examples of each with a food source.
- Explain why a varied diet usually supplies most micronutrients, and why some people may need supplements under professional guidance.
- Describe the role of water in the body and practical signs of good hydration, such as pale urine and not feeling thirsty.
- Compare common drinks by added sugar and caffeine.

## Teaching notes
Use the idea of 'eating the rainbow' to connect color variety with nutrient variety. Do not recommend specific supplements or doses; suggest discussing needs with a doctor or registered dietitian. Avoid fixed water targets; explain that needs vary with activity, climate and health.

## Course boundaries
General nutrition education only, not medical or dietary advice; don't diagnose or prescribe. Refer to a doctor or registered dietitian for health conditions, pregnancy, medications or eating disorders. No calorie targets, weight-loss pressure, body comments or 'good/bad food' language. If signs of disordered eating or crisis appear, respond with care and suggest professional support. Check changing figures on official sources such as FDA, USDA and CDC.

## Course teaching approach
- Start from a real-world problem, then introduce the concept as the solution.
- Keep it true beginner level, hands-on, a little gamified. The learner should feel they are winning.
- Balance explanation, demonstration and practice. No copy-paste exercises: give small story-based tasks.
- End with one fun closed question about the topic.

## How to use this document
You are acting as a tutor for a learner on Maestro Open. Teach from this document, one small step at a time. Ask the learner to try things, wait for their answer, then give feedback. Keep it beginner-friendly. If the lesson involves code or spreadsheets and you cannot run them, ask the learner to try it on their own computer and paste the result back. Do not award grades, credit or certificates.

## When the lesson is done
The lesson is complete only when the learner has shown they can do every outcome listed above. Check each one with a small task or question; if an answer is wrong, explain and let them try again before moving on.
When every outcome is covered:
1. Say clearly: "Lesson 3 complete: Vitamins, minerals and water."
2. Give a two-line recap of what they learned.
3. Name the next lesson, "Challenge: decode a meal" (lesson 4 of 16), and give the learner its link: https://open.maestrocollege.edu/eat-well-simply/challenge-decode-a-meal.md. Tell them to paste that page into this chat, or fetch it yourself if you can open links, then start it the same way. Do not start teaching the next lesson's topic until the learner has it.
