Define a balanced diet, explain the food groups, and use the food pyramid or My Healthy Plate to plan healthy meals

What this dot point is asking

The syllabus wants you to define a balanced diet, know the food groups and what each contributes, and use a food guide such as the food pyramid or Singapore's My Healthy Plate to plan healthy meals. The central idea is that healthy eating is about proportions: getting all the nutrients in the right amounts, with staples and vegetables forming the bulk and fatty, sugary foods kept small.

The answer

What a balanced diet means

A balanced diet supplies all the nutrients the body needs - proteins, carbohydrates, fats, vitamins, minerals, fibre and water - in the correct proportions, and provides the right amount of energy for that person. "Right amount" depends on the individual: a growing teenager and an inactive older adult need different totals.

The food groups

• Wholegrains and starchy staples (rice, noodles, bread, potatoes): the main source of energy and fibre.
• Fruit and vegetables: rich in vitamins, minerals, fibre and water, with little fat; a wide variety is encouraged.
• Protein foods (meat, fish, eggs, pulses, tofu, dairy): for growth, repair and maintenance, and minerals such as iron and calcium.
• Fats, oils, sugar and salt: needed only in small amounts; too much raises the risk of obesity, heart disease and high blood pressure.

Food guides: the pyramid and My Healthy Plate

A food pyramid shows proportions by area: a wide base of wholegrains, a large band of fruit and vegetables, a smaller band of protein foods, and a small tip of fats and sugars. The wider the band, the more you should eat from it.

Singapore's My Healthy Plate shows the same advice as a single plate divided into thirds and quarters: fill half the plate with fruit and vegetables, a quarter with wholegrains, and a quarter with protein foods, choose water as the drink, and use a little oil. It is an easy, visual way to check a meal at a glance.

Using the guide to plan

To plan a balanced meal, start with the proportions, not the dish: make sure vegetables fill the largest share, choose a wholegrain staple, add a sensible protein portion, keep added fat and sugar small, and drink water. The same approach lets you fix an unbalanced meal by adjusting what is over- or under-represented.

Examples in context

Example 1. A balanced economy rice plate. At a cai png stall, a balanced choice is brown rice, two vegetable dishes, one lean protein such as steamed fish or tofu, and water. Loading up on fried items and gravy with little vegetable unbalances the same meal, showing how the guide helps even with everyday hawker food.

Example 2. A school recess set. Swapping a sausage bun and sweet drink for a wholemeal sandwich with egg, a piece of fruit, and water turns a recess snack into something close to My Healthy Plate proportions, adding fibre and protein while cutting sugar.

Try this

• Cue. Define a balanced diet in full. State that it supplies all nutrients in the correct proportions and the right amount of energy for the person.
• Cue. State the My Healthy Plate proportions and what to drink. Recall half fruit and vegetables, a quarter wholegrains, a quarter protein, with water.
• Cue. Suggest two changes to balance a meal of white rice, fried chicken and a sweet drink. Add vegetables and fruit to fill half the plate, and swap the sweet drink for water.
