Explain what is meant by a balanced diet and use the My Healthy Plate guide to plan healthy meals

What this dot point is asking

SEAB wants you to explain what a balanced diet is and to use Singapore's My Healthy Plate guide to plan healthy meals. The big idea is that no single food gives the body everything it needs, so health comes from eating a variety of foods in the right proportions. The marks come from a clear definition, knowing what each food group provides, and being able to look at a meal and adjust it to match the My Healthy Plate proportions.

The answer

What a balanced diet means

A balanced diet is one that supplies all the nutrients the body needs (protein, carbohydrate, fat, vitamins, minerals, fibre and water) in the correct amounts and proportions, providing enough energy for daily life but not too much. Because no one food contains everything, a balanced diet relies on variety.

What each food group provides

Healthy eating brings together the main groups:

• Carbohydrate staples (rice, noodles, bread, especially wholegrain) for energy.
• Protein foods (meat, fish, eggs, beans, tofu) for growth and repair.
• Fruit and vegetables for vitamins, minerals and fibre.
• Dairy and calcium foods (milk, cheese, tofu) for strong bones.
• A small amount of fat or oil for energy and to carry vitamins.
• Water to keep the body working.

My Healthy Plate

Singapore's My Healthy Plate (from the Health Promotion Board) is a simple picture of a healthy meal. It divides the plate into three parts:

• Half the plate: fruit and vegetables, for vitamins, minerals and fibre.
• A quarter: wholegrains and other carbohydrate staples, for energy.
• A quarter: meat and others (protein foods), for growth and repair.

It also reminds you to drink plain water, use a little healthy oil in cooking, and stay active.

Using My Healthy Plate to plan a meal

To plan a meal, start with the plate proportions: fill half with vegetables and fruit, a quarter with a wholegrain staple, and a quarter with a protein food. This makes balance automatic without counting nutrients one by one.

Examples in context

Example 1. A balanced economy rice plate. Choosing brown rice (a quarter of the plate), one lean protein such as steamed fish or tofu (a quarter), and two vegetable dishes (half), with plain water to drink, turns a typical cai png (economy rice) meal into one that closely matches My Healthy Plate. This shows the guide working with everyday Singapore food.

Example 2. Balancing a fast-food meal. A burger meal of a large burger, fries and a sweet drink is heavy on carbohydrate, fat and sugar with little fruit or vegetable. Swapping the fries for a side salad, choosing plain water, and adding fruit later shifts it towards the My Healthy Plate proportions, showing how balance can be improved even when eating out.
