Planning balanced diets

GCSE Food Preparation and Nutrition revision notes, key terms and practice questions.

The Eatwell Guide

  • The Eatwell Guide shows the proportions of food groups for a healthy, balanced diet.
  • Fruit and vegetables: just over a third; aim for at least 5 portions a day.
  • Potatoes, bread, rice, pasta and other starchy carbohydrates: just over a third; choose wholegrain.
  • Beans, pulses, fish, eggs, meat and other proteins: eat more beans and pulses, 2 portions of fish a week (one oily), and less red and processed meat.
  • Dairy and alternatives: choose lower-fat and lower-sugar options.
  • Oils and spreads: unsaturated types, in small amounts. Drink 6 to 8 glasses of fluid a day.

Needs at different life stages

  • Babies and toddlers: breast or formula milk at first; toddlers need full-fat milk and energy for growth.
  • Children and teenagers: energy and protein for growth, calcium and vitamin D for bones, and iron (especially girls).
  • Adults: a balanced diet to maintain health and avoid weight gain.
  • Older adults: fewer calories but plenty of calcium, vitamin D, fibre and fluid.
  • Pregnant women: folic acid, iron, calcium and vitamin D; avoid risky foods such as unpasteurised cheese, pâté and raw eggs.

Special diets

  • Vegetarians don't eat meat or fish; vegans eat no animal products and need B12, iron, calcium and protein complementation.
  • Coeliac disease: gluten (in wheat, barley and rye) must be avoided.
  • Lactose intolerance: avoid or limit milk sugar.
  • Nut allergy: nuts must be avoided completely, as they can cause anaphylaxis.
