Foods are sorted into food families by what they bring:
- fruit and vegetables — vitamins, fibre and water; the freshness family;
- cereals and starchy foods (bread, pasta, rice, potatoes) — the steady energy family;
- dairy (milk, yogurt, cheese) — the bone-building family;
- meat, fish and eggs — the body-building family;
- fats (butter, oil) — concentrated energy, needed in small amounts;
- sugary foods — quick pleasure, needed not at all: the treat family;
- and water — the only drink the body requires, all day long.
Examples
Example 18.4 (Balancing a lunch)
Pasta with tomato sauce, a piece of fish, green beans, a yogurt, an apple, water: every family present, treats absent — a balanced lunch. Chips, a soda and a chocolate bar feed exactly two families (fats and sugar) and skip the ones the building site was waiting for.
