LIPIDS AND ESSENTIAL FATTY ACIDS - 2023/4
Module code: BMSM008
Module Overview
The module aims to provide a detailed appreciation of dietary lipids, including their sources of origin, biochemistry, functions and essential roles in health. Building on this, the module will critically examine and evaluate evidence for the roles of specific dietary fatty acids in the prevention and management of disease.

Assessment Strategy
The assessment strategy is designed to provide students with the opportunity to demonstrate:
The summative assessment for this module consists of: COURSEWORK ASSIGNMENTS COLLECTIVELY COMPRISING A MAX OF 5000 WORDS, WHICH MAY INCLUDE A COMPULSORY ELEMENT. Addresses learning outcomes 1-7. The coursework includes a variety of tasks such as an essay, a case study, preparation of a mock government ‘white paper’ and patient information sheet.
Formative assessment
A quiz that covers basic lipid biochemistry is available on SurreyLearn, in order to reassure students that they are equipped with the prior learning required before starting the module.
Feedback
The online quiz gives a grade with feedback on an incorrect answer. The healthy fat quiz is peer-marked and feedback on the reasoning behind the correct answers will be given at the time. Feedback on the students critical evaluation of the journal articles will also be given at the time, in addition to written feedback in SurreyLearn on marked assignments.
Module aims
- To provide an appreciation of dietary lipids, including their sources of origin, biochemistry, functional roles and nature of essentiality to health.
- To nurture an understanding of lipid transport pathways in terms of lipoprotein physiology.
- To critically examine the epidemiology of dietary lipids and disease
- To provide an understanding of the pathogenesis of CHD, non-alcoholic fatty disease and cancer in relation to current research.
- To understand the role of polyunsaturated fatty acids in inflammation and immune function.
- To understand the role of nutrigenetics and nutrigenomics in relation to lipid metabolism.
- To evaluate critically the evidence in support of a therapeutic role for dietary fatty acids in the prevention and management of disease
- To provide an update on the current guidelines for the intake of dietary fat and fatty acids

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
- be aligned with the grade descriptor for qualification at level 7 in the Framework for Higher Education Qualifications (FHEQ) produced by the Quality Assurance Agency (QAA)
- use group work to continue to build students’ confidence in the critical evaluation of the scientific literature. Students typically discuss a recent publication and together, prepare a powerpoint presentation to highlight the salient points with a critical evaluation of the authors methods and conclusions. This will also allow students to develop skills in presentation are key employability and digital capability skills, as well as preparation for the assessed presentation in BMSM013.
-allow students to develop bonds with their peers and staff, during formal and informal discussions (the latter during breaks), in order to foster a good team spirit which will be beneficial for this and future modules.
- engage students with different professional backgrounds to maximise their learning by drawing on their own expertise and experiences to contribute to class discussions. The students are already aware of the diversity of their backgrounds from the introductions in BMSM001 and lecturers typically ensure a balance of experiences/professions in group work.
The learning and teaching methods include class discussions based on lectures, critical evaluation of topical journal articles (group work), case studies and a bespoke evening meal: The healthy fats dinner which is followed by the healthy fats quiz, designed to consolidate learning during the module.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

Can be taken as a stand–alone module.
Addressing the 5 pillars:
Digital Capabilities: Students on the programme have a wide range of digital capabilities, due to the varying nature of their professions and prior experience. Group work whereby students prepare presentations in a short space of time develops the skills and confidence required for the effective dissemination of science. As in other modules, students are encouraged to work together in groups, utilising collaborative tools (Whatsapp, Teams, Zoom) to communicate. These are key skills that are increasingly important to the modern nutritionist, working in a variety of settings and teams.
Sustainability: guidelines for recommending particular foods can create issues for sustainability of natural resources and this is the case for the recommendations for oily fish. In this module we discuss the scale of the problem in terms of world resources and students consider the pros and cons of alternatives.
Resourcefulness and resilience: students on the module will be at various stages in their journey; it could be their second taught module out of nine, or it could be their ninth. Students at the earlier stages discuss strategies with those in the later stages, to plan workloads which must often be fitted into a busy working life. This is encouraged during coffee and meal breaks. Meals are taken at round tables to encourage discussion and the ‘coffee queue’ encourages introductions and small steps to developing a network of support in the module and overall programme.
Global and cultural challenges: Introduction and engagement with diverse perspectives such as through guest speakers or case studies from a range of countries, cultures and environments, discussions and problem-solving of global challenges.
