AoS 2 SAC HHD nutrition Flashcards
six categories of nutrients required for optimal health and wellbeing
carbohydrates, protein, fats, water, vitamins and minerals
youth require a balance of
the six categories of nutrients in order to maintain optimal health and wellbeing
the main function of carbohydrates is
as the preferred energy source
fibre is
a type of carbohydrate that is indigestible. fibre has numerous health benefits, such as reducing hunger, and decreasing cholesterol and glucose absorption
protein is
required for the growth, maintenance and repair of body cells and structures. it can also be used as a secondary energy source
water is required for
many body processes, including functioning as a medium for all chemical reactions in the body and forming an important part of blood and soft tissues.
calcium is
an important component of hard tissues and is required to achieve optimal peak bone mass.
Iron is
required for haemoglobin in blood and a deficiency can lead to anaemia
Vitamin D is
required in order for calcium to be absorbed in the small intestine and therefore assists in building hard tissue
The B-group vitamins are
required to release energy from carbohydrates, protein and fat
Folate and vitamin B12 play a role in the
development of red blood cells, which enable oxygen to be transported around the body correctly
Food-selection models can be used as
tools to assist youth in preventing nutritional imbalance
