Food technology
Nutrients
Proteins
Helps absorb vitamins A and D
Needed for growth and repair of worn out body cells and tissues, Helps form bone, muscle and hair, nails, skin, and organs such as the liver, brain, heart and kidneys
Build enzymes and hormones for normal body functioning, especially in rapid growth years
Carbohydrates
Broken down to glucose in the body, gives cells energy to function, is the primary source of fuel for the brain
Large amounts of energy expenditure require sustained amounts of carbohydrates, as people grow their energy and activity output increase and their carbohydrate intake must too increase
Fats and lipids
Essential for supplying the body with omega 3 and omega 6 essential fatty acids, producing healthy cell membranes and maximising absorption of fat-soluble vitamins and antioxidants
Micronutrients
Iron
Needed to make red blood cells, and to carry oxygen around the body, essential for brain development
Need good supply of oxygen to all parts of the body, so that oxygen can release the energy from food
Calcium
Vital for growth of bones and teeth, for blood clotting and nerve cells
Sodium
Helps thyroid gland produce thyroxine, a hormone that controls the rate at which energy is produced in the body
Iodine
Cell metabolism (processes) especially muscle and nerve functioning
Too much can cause dehydration, high blood pressure, and cardiovascular problems- only needed a little bit in diets
Water
Essential for all healthy body functioning, without it the enzymes cannot properly carry out their processes
Health promotion models
Behavioural change model
Provides information about ways to improve and enhance health and expects people to incorporate the advice into their own lives
Uses health campaigns- posters, television and leaflets
Is a passive approach in which people are told what they need to know
educates people about their health
Focuses on medical professions' views of health needs and suggests they know best
Tendency to blame the victim
Ignores determinants of health, which can be adding or causing to the health issue
Has moralistic tones- tells us what is right and what is wrong
Does not take a whole community approach- self directed and aimed towards an individual
Ignores factors in social environment that affect peoples health, so is largely ineffective because it rarely brings sustained change in peoples behaviour
Can quickly raise awareness of health issues to many people, can usually be inexpensive
Self-empowerment model
Develops a persons sense of identity and helps the person reflect on themselves and society
Helps people change their views and clarify their attitudes and values concerning health-related issues
Develops life skills, including decision making and problem solving that people can use to take control of their own lives
People are able to know how to seek help
Encourages independent actions
Helps individual recognise and understand the determinants of health that might be beyond their control
Enhances self-awareness, focusing on the individual
Nurtures resilience and empowerment at a personal level
It is not targeted at population groups and thus is unlikely to affect social norms
Only successful for an individual because it provides information, skills and support and empowers them to make their own change
Collective action model
Shared and combined action
Educates for health, empowering people to make changes by giving them skills, knowledge and support
Whole community/school approach where critical action/thinking is used in relation to the individual, others and community
Holistic approach to wellbeing, includes all dimensions of hauroa
Views people as the social agents of change, action is not done for them, but they have to actively create change themselves
Concentrates on 'student centred learning', building on what people already know and helping them gain new understanding
Can take a long time to get a group of people to agree on a process or thereby implement change
People come together to work collectively to improve health outcomes for people and the community. It considered all dimensions of hauroa, it is likely that it achieves all its intended outcomes, because people become invested in the project
