Describe one of the principles of research
Recognition of credible sources: information that is trustworthy and presents unbiased information backed by facts that are supported by evidence. Written by professionals in the field and information is free from errors and bias.
Evidence-based information: 55000 pieces of published scientific research; literature reviews; detailed randomised controlled trials; utilised other reports from reliable sources to construct knowledge
Accurate analysis of data: systematically analysed evidnece and data in literature; used a review panel to sought advice from a wide range of experts and professionals

Discuss the way in which the development of smart phones has influenced food marketing.
- Most children over 12 and adults have smartphones, which enable them to access the latest information wherever they are.
- The smartphone has had a major impact on food marketing as it has become an integral part of the shopping experience both in-store and at home.
-More families have moved to shopping online and use their mobile devices to browse and order food from the supermarket.
- Mobile devices provide consumers with a way to connect with food marketers by using personalised shopping apps to guide supermarket choices based on what they like to eat, what fits their lifestyle or their health requirements.
- Mobile content advertising is growing and food advertising is pushing this growth.
Explain the role of the liver in digestion
It is in the small intestine.
It produces bile a chemical that is released into the duodenum to physically break down to emulsify fat.
Explain how the Australian Guide to Healthy Eating could be used to assist a family in planning their daily food intake.
The Australian Guide to Healthy Eating is a visual representation of Australian Dietary Guideline 2. It is a practical reference for families to use when planning the types and quantities of foods that they need to eat daily to have a healthy diet. It also displays discretionary foods that they should limit or avoid. It is designed as a picture of a plate so it is useful for children or non-English speaking migrants or refugees who can recognise images but may not be able to read information about a healthy diet

Discuss the way the colour used in the design of food packaging can influence consumer choice. Select three colours and give examples of products that match the emotion linked to each colour.
Colour plays an important role in marketing food because consumers take only moments to make a decision to pick up a product from the shelves, and colour registers much faster than the text written on the package. The use of colour is also intended to appeal to consumers’ values and emotions.
Purple – Cadburys chocolate – quality, passion
Red – Coca-cola – fun, excitement
Green – Organic product ranges – growth, harmony, nature
Identify and describe the role of two enzymes released by the pancreas in the enzymatic hydrolysis of protein

Explain the possible implications for the health of Australians of not eating the recommended number of serves of vegetables and fruit each day over an extended period.
People who eat few vegetables over an extended period of time are more likely to gain weight gain and become obese and therefore of developing lifestyle diseases including cardiovascular disease and type 2 diabetes.
Explain how purchasing a box of ingredients to prepare healthy meals could impact on the social factors of available time and income.
Purchasing from ‘Meals in a moment’ helps a consumer to maximise the time available to them for meal preparation as they can select the week’s menu when sitting at their desk – they do not need to plan, spend time going to the shops and selecting and purchasing the meals for the week. The food is delivered to the door, and is portioned, and some components of the meal pre-prepared which is a valuable time-saving option for a busy consumer. All the consumer needs to do is pack it into the refrigerator and cook it when they are ready. If the consumer is purchasing for one or two people this form of shopping for healthy meals is cost-effective as the cost of the ingredients is low especially when the time spent shopping it considered. However, if purchasing food for a family of 5-6 people, it may become much more expensive than shopping for the ingredients and completing the meal preparation as a family.
Outline how dairy foods can boost gut health.
Dairy foods such as yoghurt contain living beneficial bacteria (probiotics) that boost gut health and also influence mood and wellbeing.

The following graph identifies the number of serves of the grain (cereal) foods, mostly wholegrain and/or high cereal fibre varieties food group for 5 year old girls, 35 year old women and pregnant women.
Explain the reasons that account for the differences in the number of serves of grain foods required by 5 year old girls, 35 year old women and pregnant women.
The larger number of serves of grains is required by pregnant women to support the extra energy required to support the growth of foetal and maternal tissue. It is necessary for a 35 year old woman to maintain a nutrient dense diet that includes grain foods. Their energy needs are not as high as a pregnant woman but are required to support maintenance and repair of damaged tissues and to provide energy for physical activities. A 5 year old will require the lowest amount of serves as they have lower energy needs based on slow and steady growth during this lifespan stage.
Describe how positive role models can influence healthy eating behaviours in children
Positive role modelling of food behaviours by parents, families and childcare staff sees children imitate and observe adult behaviours. If children see food being enjoyed and spoken about in positive terms, they will be more interested in it and be more open to experimenting with new foods. This in turn develops healthy eating habits.
Why is it important to avoid discretionary foods when feeling tired and stressed?
Discretionary foods such as chocolate and sugary drinks might give an immediate boost of energy but invariably it is only short lived, and the person may in fact feel worse a little later.

Describe the relationship betweem gut microbiota and physical health
Gut microbiota assist the digestion of fibre by fermenting indigestible carbohydrates and resistant starches into short-chain fatty acids. These are important for physical health:
Suppress appetite helping to maintain a health weight and prevent individuals from becoming overweight.
Support the immune system and improve resistence to infections by inhibiting the growth of harmful mircroorganisms
Justify why a product such as microwavable brown rice and quinoa would be suitable for someone who is gluten intolerant.
Both these products would be suitable for a person who is gluten intolerant as rice and quinoa do not contain the protein gluten.
Provide 3 examples of how young children can be involved in the preparation of family meals
Children can be involved in planning meals and shopping for ingredients.
Children should be encouraged to prepare their own lunch as they are more likely to make healthy food choices if they are involved.
Children should be given age-appropriate tasks in preparing and cooking meals such as measuring ingredients, cutting vegetables, stirring foods and as they become more confident, they can take on more complex tasks.
