Carbohydrate
•What is the role of carbohydrate?
•What are 3 good sources of carbohydrate?
•What is the glycaemic index?
•What is the role of fibre?
Protein
•What is the role of protein?
•What are 3 good sources of protein?
Fats
•What is the role of fat?
•What are 3 sources of fats?
•What are the 4 categories of fats? (Which are good and bad sources)
VITAMINS There are 2 types of Vitamins
1. Fat Soluble Vitamins- Absorbed and dissolved in the body by fats
2. Water Soluble Vitamins- Dissolved in the body by water
VITAMINS
FAT Soluble Vitamins
WATER Soluble
Vitamins
VITAMIN A
VITAMIND
VITAMINE
VITAMINK
VITAMINB’s
VITAMINC
Including folate
VITAMIN D - FAT SOLUBLE VITAMIN Function:
Helps calcium and phosphorus be absorbed into the body from the intestines
Formation of hard tissue eg bones and teeth Deficiency
Osteoporosis – a common musculoskeletal condition caused by a lack of vitamin D leads to weakened bones
Rickets in children Becoming more common
Sources: 10% from diet
UV rays are fish is a egg yolksConverted to good source contain Vitamin D small amounts
Sources Some brands of milk, breakfast cereals and
orange juice are fortified with vitamin D
Minerals
Calcium Phosphorus Sodium
CALCIUM
Function Strengthening , ossifying agent for hard tissue such as
teeth and bones Involved in muscle contractions, the secretion of
hormones, enzymes and the functioning of the nervous system
Calcium needs high for young children, teenagers, menstruating women and the elderly
If individuals do not get enough calcium they are unlikely to reach peak bone mass. It is important for maintaining good bone health throughout life
Sources Diary foods Sardines Green leafy veges Fortified soy milk and breakfast cereals.
CALCIUM AND THE NHPA’S
Osteoporosis Hardens bones and assists in the prevention of
osteoporosis.
PHOSPHORUS
Works with calcium to harden bones and teeth
Calcium and phosphorus bind to form calcium phosphate which ossify hard tissue
Phosphorus is also a component of DNA It assist in the contraction of muscles and
functioning of kidneys
Sources Foods rich in protein Meat, fish, eggs, nuts, legumes
PHOSPHORUS AND THE NHPA’S
Osteoporosis Works with calcium to harden bones and assists
in the prevention of osteoporosis.
SODIUM Role in regulation of body fluids Regulates balance of fluids in cells Electrolyte – important for brain function and muscle
contraction. Most Australians get 8 – 9 times the sodium they
require. This draws fluid out of the cells which increases blood volume and contributes to hypertension
Sources Most from processed foods
Biscuits, chips Take away foods eg pizza, hot chips Processed meats Table salt
SODIUM
Excess sodium leads to hypertension ( high blood pressure)
Other effects include Heart failure Kidney problems, kidney stones Stroke and heart attack Osteoporosis
Sodium deficiency due to loss of body fluids Cramps, dizziness dehydration
SODIUM AND THE NHPA
Cardiovascular health Excess sodium accumulates in the blood. As it
retains water this increases blood volume and blood pressure. Which can contribute to hypertension.
Hypertension is a risk factor for CV disease Osteoporosis
Excess sodium can interfer with calcium absorption leading to weaker bones and osteoporosis
THE IMPORTANCE OF NUTRITION AS A RISK AND PROTECTIVE FACTOR FOR THE NHPA’S
The key to healthy food intake is balance The nutrients play an important role in
maintaining health Incorrect quantities can have a negative effect on health
