Energy-producing nutrients
The nutrients that supply us with energy are carbohydrates, proteins and fat.
| Carbohydrate | Source |
|---|---|
| Sugars | Fruits Honey |
| Lactose | Milk Dairy products (milk sugar) |
| Starches | Corn Wheat Rice Barley Oats Potatoes |
| Slowly fermentable fibre like cellulose | Wheat bran |
| Moderately fermentable fibre | Rice bran Pea fibre Wheat bran |
| Rapidly fermentable fibre | Apples Citrus pulp Guar gum |
Tasty Tips
Simple carbohydrates and starches in foods are used by the body as a source of glucose. As such, they have several major functions, they:
- provide energy
- produce heat when they are metabolized for energy
- can be used as building blocks for other nutrients (e.g., certain amino acids, lactose (the sugar in milk) and vitamin C)
- provide storage of energy in the form of glycogen or fat
