NUTR404 Advanced Culinary Nutrition Science

Unit rationale, description and aim

Special diets are not a new phenomenon yet in recent years the perceived and real need for foods for special diets has increased dramatically. Through a contemporary analysis of the place of special diets within our modern foodscape this unit builds on NUTR404 Advanced Culinary Nutrition Science and facilitates students’ critical examination of popular and evidence-based diets for the maintenance of health and treatment of disease. Students will be expected to develop advanced menu, food and specialist ingredient knowledge, in-depth understanding of special diet food regulations and food service standards and utilise their advanced food planning, preparation and cooking skills to prepare a range of foods to meet the requirements of specific diets. This unit aims to assist students develop the ability to evaluate the theoretical and practical elements of contemporary diets and communicate this to audiences in engaging and influential formats.

Learning outcomes

To successfully complete this unit you will be able to demonstrate you have achieved the learning outcomes (LO) detailed in the below table.

Each outcome is informed by a number of graduate capabilities (GC) to ensure your work in this, and every unit, is part of a larger goal of graduating from ACU with the attributes of insight, empathy, imagination and impact.

Explore the graduate capabilities.

On successful completion of this unit, students should be able to:

LO1 - Evaluate and synthesise the scientific evidence related to foods and diets designed for specific purposes (GA4, GA5, GA8)

LO2 - Illustrate highly developed food and ingredient knowledge, planning, preparation and cooking techniques, along with in- depth understanding of regulatory considerations through the preparation and presentation of a range of foods/meals for special diets (GA5, GA7, GA9)

LO3 - Demonstrate highly efficient workflow planning and operation in a commercial kitchen environment with a focus on special diet requirements (GA4, GA5, GA7)

LO4 - Present scientific and practical evidence in highly engaging formats for a range of audiences (GA4, GA5, GA8, GA9, GA10)

Graduate attributes

GA4 - think critically and reflectively 

GA5 - demonstrate values, knowledge, skills and attitudes appropriate to the discipline and/or profession 

GA7 - work both autonomously and collaboratively 

GA8 - locate, organise, analyse, synthesise and evaluate information 

GA9 - demonstrate effective communication in oral and written English language and visual media 

GA10 - utilise information and communication and other relevant technologies effectively.

Learning and teaching strategy and rationale

The unit content will be delivered intensively over 4 weeks, with submission of final assessment following. The intensive practical component of this unit is will be delivered concurrently with a post-graduate foods for special diets unit designed to meet the needs of food and nutrition professionals in practice wishing to up-skill, and as a unit in the proposed post-graduate dietetics degree. The theory component will be delivered over a 2-week period followed by the practical component.

The learning and teaching strategy adopted aligns with the sequencing of the learning outcomes and consists of three phases that are designed to provide students with a developmental learning experience. The unit begins with approaches designed to support acquisition of specialist knowledge related to foods for special diets and then follows with the development of a theoretical understanding of concepts and principles needed to inform the skills development, workflow planning in commercial kitchens and presentation of scientific evidence. The approaches used to facilitate students’ learning include online learning modules and readings and will be delivered in the first two weeks of the unit. The unit builds on this theoretical knowledge and assists students to develop understanding and application of advanced culinary nutrition science specifically related to foods for special diets through practical classes. Overall, the approaches used in this unit have a constructively aligned developmental sequence designed to progressively and logically support students learning in ways that maximise the perceived (and actual) relevance and value of each stage. As an overarching strategy, this is expected to engender high levels of engagement, efficiency and effectiveness in students’ study behaviours, and to maximise their learning achievements.

This strategy and approaches will allow students to meet the aim, learning outcomes and graduate attributes of the unit. Learning and teaching approaches will reflect respect for the individual as an independent learner. Students will be expected to take responsibility for their learning and to participate actively in learning activities.

Assessment strategy and rationale

In order to best enable students to achieve unit learning outcomes and develop graduate attributes, standards-based assessment is utilised, consistent with University assessment principles and requirements. A range of assessment strategies will be used in ways that support the developmental sequence of the learning and teaching strategy. Thus, the three phases of the strategy are reflected by integration of three appropriate assessment tasks. The first, involves a written assessment task submitted within the first two weeks, and prior to the commencement of the practical component with feedback provided prior to submission of the second written assessment task. This task provides students with the opportunity to demonstrate their ability to evaluate the evidence for a specific and current food or diet trend. The second assessment task extends this theoretical understanding by requiring students to demonstrate practical application of the knowledge and skills required to prepare foods for special diets that meet regulatory requirements (where appropriate). This task provides students with practical by practical assessment and feedback on their ability to prepare and cook specific foods/meals. The final assessment task allows students to bring together their theoretical and practical knowledge, understanding and skills of food for special diets and communication for popular media in a written task that requires critical writing skills pitched at diverse audiences. The assessment tasks will allow unit coordinators to assess students’ demonstration of the learning outcomes and attainment of graduate attributes.
