Health conditions

I can describe how diets can be changed for health.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Health implications are caused by poor diet (dietary excess or deficiency), e.g. obesity, bone health, heart disease.
  2. Nutrition, ingredient and allergy information on food labels help us to make informed food and drink choices. 
  3. Meals and diets can be planned and evaluated for the needs of different groups of people.

Keywords

  • Malnutrition - intakes of energy and/or nutrients below or in excess of needs for long periods of time

  • Undernutrition - having an intake of energy and/or nutrients below what is needed

  • Overnutrition - having an intake of energy above what is needed

  • Coronary heart disease - a health condition caused by the narrowing of the blood vessels to the heart

  • Obesity - a health condition caused by too much energy (calories) being consumed, or high levels of inactivity

Common misconception

There is one form of malnutrition, intakes of energy and/or nutrients being below what is required.

There are two forms of malnutrition: undernutrition (intakes below what is required) and overnutrition (intakes above what is required).
