  2. Last Lesson Revision • 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)

  3. Vitamins • There are 2 types of Vitamins • Fat Soluble Vitamins - Absorbed and dissolved in the body by fats • Water Soluble Vitamins - Dissolved in the body by water

  4. VITAMINS FAT Soluble Vitamins WATER Soluble Vitamins VITAMIN A VITAMIN D VITAMIN E VITAMIN K VITAMIN B’s VITAMIN C Including folate

  5. 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

  6. Sources • Some brands of milk, breakfast cereals and orange juice are fortified with vitamin D

  7. 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.

  8. Calcium and the NHPA’s • Osteoporosis • Hardensbones and assists in the prevention of osteoporosis.

  9. 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

  10. Phosphorus and the NHPA’s • Osteoporosis • Works with calcium to hardenbones and assists in the prevention of osteoporosis.

  11. 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

  12. 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

  13. 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

  14. 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

  15. Cardio vascular Health • Nutrient Examples in food Function as a protective factor affect on Health. • Nutrient Examples in food Function as a risk factor affect on Health.

  16. Colorectal Cancer • Nutrient Examples in food Function as a protective factor affect on Health. • Nutrient Examples in food Function as a risk factor affect on Health.

  17. Diabetes Mellitus • Nutrient Examples in food Function as a protective factor affect on Health. • Nutrient Examples in food Function as a risk factor affect on Health.

  18. Osteoporosis • Nutrient Examples in food Function as a protective factor affect on Health. • Nutrient Examples in food Function as a risk factor affect on Health.

  19. Obesity • Nutrient Examples in food Function as a protective factor affect on Health. • Nutrient Examples in food Function as a risk factor affect on Health.
