This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils explore key nutritional needs throughout life, and allergies, food labelling, portion size and health conditions. They plan dishes and menus, and describe how diets can be changed for health to meet the needs of different groups of people.
Lesson Summary
You will learn to plan meals for different dietary requirements, with justification.
Key Notes
- Dietary needs change at key age and life stages.
- Some people have an allergy or intolerance to specific foods. 14 major allergens are listed on food packaging.
- Portion sizes change through life. There are consequences of excess (servings of food and their portion size).
- Recipes and meals can be adapted for different dietary requirements.
Vocabulary To Learn
- DRVs: dietary reference values - energy and nutritional requirements for different groups of healthy people in the UK population
- EARs: estimated average requirements - an estimate of the average requirement of energy, or a nutrient, needed by a group of people
- RNIs: reference nutrient intakes - the amount of a nutrient that is enough to ensure that the needs of nearly all people in a group are being met
- LRNIs: lower reference nutrient intakes - the amount of a nutrient that is enough for only a small number of people in a group who have low requirements
Common Mistakes To Avoid
- Dietary Reference Values (DRVs), nutritional requirements, are intended for individual healthy people.
