Main food sources: |
-Carbohydrates -Fats -Proteins |
|
|
How is macronutrients and micronutrients different from each other? |
Macronutrients are needed by the body in large amounts (carbohydrates, proteins, fats) whereas micronutrients are needed in the body in small amounts (vitamins and minerals) |
|
|
Carbohydrates... |
-provide fuel for energy -carbohydrates are rich in glucose. Glucose is preferred fuel for energy in the human body -pasta, rice, corn |
|
|
Fibre... |
-found in all foods that is plant origin -travels through the digestive system as a cleaner as it travels |
|
|
Protein.. |
-main function is to build, repair and maintain body cells (building of soft tissues and hard tissues) -3rd fuel for energy -meat, fish, egg |
|
|
Fat.. |
-responsible for maintaining the structure of cells -required for development and maintenance |
|
|
Monounsaturated and polyunsaturated fats.. |
-good fats -carry out the necessary function fats and also have some health benefits -olive oil, avocado, nuts -fish, canola oil, soy |
|
|
Saturated and trans fats... |
-bad fats -increase cholesterol levels in blood which can contribute to heart disease in long term -found in animal origin, full cream milk, cream, cheese |
|
|
Function of water: |
-as a medium for all chemical reactions required to provide energy and produce energy -a key component of many cells, tissues and systems -key component of blood -dehydration may cause: lack of alertness, lose concentration, less activity |
|
|
Calcium is.. |
-a key nutrient for building of bones and other hard tissues -greater the bone density lesser chance of osteoporosis -milk, cheese, yogurt (mostly dairy products) |
|
|
Iron.. |
-essential part of blood -iron forms the 'haem' part of the haemoglobin which carries is the oxygen carrying part of blood -lean red meat, turkey, chicken, vegetables |
|
|
What is anaemia? |
a condition characterised by tiredness and weakness due to lack of iron |
|
|
Function of Vitamin A |
-required for cell division -involved in cell differentiation -promote development of bones -assist in the development of immune system -raw carrots, potatoes, spinach |
|
|
Function of vitamin B1,2,3 |
-essential in metabolism -converts fuels for the body -fish, meat, eggs |
|
|
Function of Vitamin B9 |
-plays a role in the development of red blood cells -bread, green leafy vegetables, citrus fruits |
|
|
Function of B12 |
-ensures that red blood cells is in the right size and ensures the red blood cells to enable oxygen to be transported in the body -meat, eggs, cheese |
|
|
Function of Vitamin C |
-forms connective tissues -promotes absorption of iron -oranges, kiwi fruit, broccoli, stawberry |
|
|
Function Vitamin D |
-main role: absorption of calcium from intestine to bloodstream -sunlight, milk, orange juice, tuna |
|
|
Provision of energy includes: |
BMR (basal metabolic rate) - the amount of energy to sustain life BMR factors: -age -growth -body type -body size -dieting -sex -environmental temperature |
|
|
Blood production includes: |
Components of blood: -Plasma (contains clotting material and transports nutrients, gases, hormones and waste) -Red blood cells (carries oxygen, carbon dioxide and other gases -White blood cells (important for fighting disease and infection) -made in bone marrow -vitamin c - plays a role in blood formation -vitamin a- cell division |
|
|
Formation of soft tissues includes: |
-protein, main building material for soft tissues -vitamin c, provides collagen (glue for body's cell tissues holding them together giving them structure) -Lipids, maintenance and development of cell membranes which are the outer layer of a human cell -vitamin a - cell division |
|
|
Formation of hard tissues includes: |
-Protein, building material -Vitamin c, provides collagen -vitamin a, cell division -calcium, gives the bone strength -vitamin d, absorption of calcium |
|
|
Healthy living pyramid |
-developed by Nutrition Australia, a non government organisation Includes: 'mover more' - this section encourages physical activity 'eat more' -contains of food of plant origin 'eat moderately' - foods that should make up a third or less of any meal 'eat in small amounts' - energy dense and do not contribute significant amount of nutrients to the diet |
|
|
Medicare |
universal health insurance scheme |
