Lesson Content

Unbalanced Diet

An unbalanced diet is a meal lacking the correct amounts of nutrients our bodies need. This means eating too much or too little of specific foods.

Examples of Unbalanced Diets

An unbalanced diet involves consuming disproportionate amounts of nutrients, either in excess or deficiency. These include:

1. eating only junk food like chips and sweets.
2. Drinking too many sugary drinks and not enough water.
3. Eating lots of fried foods and not enough vegetables.
4. Skipping meals and overeating at one time.
5. Having a diet with too much fat and not enough protein.
6. Consuming excessive amounts of processed foods with high sodium content.
7. Eating predominantly one type of food group while neglecting others.

Recognising an Unbalanced Diet

An unbalanced diet supplies too much of some nutrients or too little of others over time. Eating only starchy food, regularly missing vegetables and fruit, or taking many sugary drinks and snacks are examples.

One meal does not decide a person’s whole health; the pattern over time matters. A balanced meal combines suitable energy-giving, body-building and protective foods in sensible amounts, with clean water.

• Possible effects include weak growth, tiredness, poor resistance to illness, tooth decay or unhealthy weight change.
• Food needs vary with age, activity and health, so illness-related diets should be guided by a health professional.
