Proteins · Proteins supply material for building and repairing tissues. Meat, fish and eggs are protein sources.
Carbohydrates · Bread, rice and pasta supply carbohydrates, a main source of food energy.
7 · Carbohydrates, fats, proteins, vitamins, minerals, fibre and water make seven listed components.
True · Fats provide energy. Energy held in stored body fat can be used later.
Vitamin C · Oranges and peppers supply vitamin C, which supports wound healing.
Vitamins and minerals · Vitamins and minerals support body functions but do not themselves supply food energy. Carbohydrates, fats and proteins do.
Some fibre is broken down by gut microbes. · Humans do not digest fibre like starch, but gut microbes break down some fibre and provide a little energy.
Wholegrain bread supplies carbohydrates plus fibre. · Foods are mixtures. Wholegrain bread supplies carbohydrates and fibre, so one food can contain several dietary components.
