Lesson notes

Learning Objectives

Indicator: B7.5.2.1.1 - Explain the relationship between food nutrients and common deficiency diseases and how they affect humans.

By the end of the lesson, learners can:

Name the six classes of food nutrients and state at least one major use of each in the human body.
Match specific nutrient deficiencies to their corresponding deficiency diseases (e.g. lack of protein leads to kwashiorkor, lack of iron leads to anaemia).
Describe the symptoms, effects and prevention of at least four common deficiency diseases (night blindness, rickets, scurvy, kwashiorkor).
Analyse the nutrient content of their own typical meals and identify which nutrients they may be lacking.
Present a short oral explanation connecting a local food to the deficiency disease it prevents, using clear and ordered speech.

Exemplars (from the NaCCA curriculum)

1. Name and analyse food nutrients such as carbohydrates, proteins, fatty acids, and their uses in the human body.
2. Discuss and make presentations on deficiency diseases associated with lack of food nutrients such as carbohydrates, proteins, fatty acids, vitamins and others in the human body.
3. Relate the nutrients they gain or lack to the foods they normally eat e.g. lack of protein leads to kwashiorkor, lack of iron lead to anaemia, etc.
4. Describe symptoms, effects and prevention of common deficiency diseases such as night blindness, rickets, scurvy, kwashiorkor and others.
