Portion sizes

This Food Fact Sheet will share the suggested portion sizes of typical foods.

What is a portion of food?

A portion is the amount of a food that you eat at one time, for example how much food you put on your plate at a meal or how much is in a packet.

Why are portion sizes important?

The key to eating a balanced diet is to eat a wide variety of foods in appropriate amounts. Making healthier choices and choosing to eat some foods more often, and in larger amounts, than others.

It is important to be aware of portion sizes, as eating too much or not enough of any type of food can increase your risk of health problems. This is because your body may be getting too much or too little of what it needs to stay healthy.

As every person is different, the recommended number of portions for each food will vary according to age, sex, size, health and other factors, but this sheet provides a good place to get you started.

Drink plenty of fluids – generally six to eight cups or glasses daily but this will depend on age, gender, the weather, how much physical activity you do and health. Water, lower fat milks, lower sugar or sugar-free drinks including tea and coffee all count. Younger children need relatively smaller servings (150ml-200ml) whereas older children and adults need larger servings (250ml-300ml).

Fruit juice and smoothies should be limited to one small glass (150ml) per day at a mealtime to protect your teeth.

Mixing food types and portions

People will often have more than one portion of one food type at each meal.

Based on the portion sizes above:

  • A sandwich with two slices of bread with two teaspoons of spread (one on each slice) would be two portions of carbohydrates and two portions of fats
  • A meal including meat or fish plus beans or pulses would be two portions of protein
  • A meal containing broccoli and carrots would be two portions of vegetables
