Nutrition and Balanced Diet
What is it?
A balanced diet supplies energy, essential nutrients, fibre and water in suitable amounts. Needs vary with age, activity, health and physiological state.
In simple words
- A balanced diet supplies energy, essential nutrients, fibre and water in suitable amounts. Needs vary with age, activity, health and physiological state.
- Understanding nutrition and balanced diet connects structure, mechanism and biological outcome. It helps explain how a change at one level can affect the whole organism, population or environment.
- A complete answer on nutrition and balanced diet links the starting condition to its mechanism and outcome.
Important terms
Nutrition and balanced diet: A balanced diet supplies energy, essential nutrients, fibre and water in suitable amounts. Needs vary with age, activity, health and physiological state.
Mechanism: Start with the trigger or starting condition, follow the biological structures and signals in order, and finish with the response or product. For nutrition and balanced diet, the central relationship is: A balanced diet supplies energy, essential nutrients, fibre and water in suitable amounts. Needs vary with age, activity, health and physiological state.
Biological significance: Understanding nutrition and balanced diet connects structure, mechanism and biological outcome. It helps explain how a change at one level can affect the whole organism, population or environment.
What you should learn
- Define nutrition and balanced diet in accurate biological language.
- Explain the mechanism or relationship involved in nutrition and balanced diet.
- Apply nutrition and balanced diet to a comparison, prediction or Federal Board exam question.
Examples
- Identify the starting condition
- Name the active structure or molecule
- Trace the direction of change

Remember
- ordered mechanism
- clear outcome
Examples
- Define before explaining
- Use arrows for a sequence
- Compare on the same basis
- Add one relevant example
Remember
- nutrition and balanced diet
- cause → mechanism → outcome
- nutrition, and, balanced
- definition · mechanism · significance
- avoid vague or reversed statements
- nutrition and balanced diet
- accurate biological link
- ordered mechanism
