What is covered in WJEC Food Preparation and Nutrition Area 3?

Area 3, Diet and good health, covers energy in the diet and energy balance, how to plan a balanced diet using the Eatwell Guide and the UK dietary guidelines, how nutritional needs change across life stages and for different groups, and the diet-related health conditions caused by a poor diet, plus food allergies and intolerances. It applies the nutrition from Area 2 to real people and health.

Which exam assesses diet and good health?

Diet and good health is assessed in Component 1, the written exam (Principles of Food Preparation and Nutrition), worth 50% of the GCSE, and it underpins the nutritional analysis in the Component 2 non-exam assessment. Questions often set the content in the context of a named person, asking you to plan or adapt a diet or to explain a health risk.

What is the Eatwell Guide?

The Eatwell Guide is the UK government model that shows the types of food and the proportions needed for a healthy, balanced diet, drawn as a plate. Fruit and vegetables and starchy carbohydrates form the largest sections, with smaller amounts of protein foods and dairy or alternatives, a little oil, and foods high in fat, salt and sugar eaten only occasionally.

How should I revise diet and good health?

Learn energy balance and the factors affecting energy needs, the Eatwell Guide sections and the dietary guidelines, and how needs change across life stages. Then learn the diet-related conditions (obesity, cardiovascular disease, type 2 diabetes, tooth decay, bone problems) with their dietary causes and the changes that reduce risk, and the difference between a food allergy and an intolerance. Practise applying all of this to a named person or meal.

For the official specification

The third area of content applies the nutrition science of Area 2 to real people and health. It covers energy and energy balance, planning a balanced diet, how needs change across life, and the conditions caused by a poor diet. This page maps the area and links to a focused answer page for each topic.

The diet and good health content

Energy and energy balance: The energy values of the macronutrients, basal metabolic rate and activity, the factors affecting energy needs, and what happens when energy in does not match energy out. See Energy and energy balance.
Making informed food choices: The Eatwell Guide, the UK dietary guidelines, and how nutritional needs change across life stages and for different groups. See Making informed food choices.
Diet-related health conditions: How a poor diet causes obesity, cardiovascular disease, type 2 diabetes, tooth decay, bone problems and some cancers, plus food allergies and intolerances and how diets are adapted. See Diet-related health conditions.

How this area is examined

Diet and good health is assessed in Component 1, the written exam worth 50% of the GCSE, and it underpins the nutritional analysis in Component 2. Expect questions that set the content in the context of a named person, asking you to plan or adapt a diet, explain a health risk, or justify nutritional advice.

How to study this area

Diet and good health rewards joining nutrition to real situations.

Master energy balance. Energy in versus energy out, and the factors that change energy needs.
Know the Eatwell Guide and guidelines. The sections, their proportions and the headline advice.
Learn the life stages. What each group (child, teenager, pregnant woman, older adult) needs and why.
Link conditions to causes. Match each diet-related condition to the dietary causes and the changes that reduce risk.
Distinguish allergy from intolerance. Know the difference and how to adapt a recipe for each.
