Key Ideas
- Balanced diet: right proportion of all nutrient groups together — no single food is nutritionally complete.
- Millets (jowar, bajra, ragi) = “nutri-cereals,” rich in vitamins, iron, calcium, fibre — but not a complete diet alone.
- Food miles: distance food travels from source to plate; choosing local/seasonal food reduces this.
- Food wastage: avoiding waste of edible food is part of mindful, sustainable eating.
- All starches are carbohydrates, but not all carbohydrates are starches (e.g., sugar is a carbohydrate but not a starch).
