Nutrition Flashcards
what are the macronutrients
carbs, lipids, protein, water
what is the main function of carbs and the role it has on youth
to provide fuel for the body, since carbs are rich in glucose which is the preferred fuel of energy for the body
provide energy that is required for metabolism and growth
what the role of fibre
- provides a feeling of fullness
- acting like a cleaner in the digestive system
- reduces the amount of cholesterol absorbed which reduces cvd
- absorbs water which assists in regular bowel movements.
food sources of fiber
grains and seed, fruit and veges : apples, bananas
what is the role of protein
to build, maintain and repair body cells
to act as a fuel for producing energy
food sources that protein is found in
soy products, fish, eggs. chicken
Fats/ Lipids roles
to act as fuel for energy
cushions organs and bones
develops cell mebranes
What is the role of monounsaturated fat

essential in the process of metabolising or converting the fuels ( carbs, protein, lipids) into energy
Food Sources: Vegemite, eggs, fish
What is the role of Folate (B9) + food sources
plays an important role in DNA synthesis and is therefore required for the cells to duplicate during periods of growth.
deficiency in folate can lead to anaemia.
Food sources: green leafy vegetables, citrus fruits
