DIETARY MINERALS IN HEALTH AND DISEASE - 2019/0
Module code: BMSM009
Module Overview
This module will enable students to understand the role of dietary minerals in health and disease. Various aspects of trace elements will be covered, including assessment of status, dietary sources, requirements, and health problems associated with both deficiency and excess.

Module content
Indicative content includes:
Some or all of the following topics
- Essentiality of dietary minerals
- Overview of dietary minerals and trace elements from a clinical perspective
- Trace element speciation: influence on bioavailability, absorption, excretion, toxicity
- Dietary mineral homeostasis
- Trace-element analysis
- Inborn errors of metabolism affecting trace-element levels
- The acute phase response (systemic inflammatory response) and its effect on trace-element distribution
- Sources; bioavailability - interactions with other nutrients, metabolism; metabolic function; assessment of status; requirements; indications for supplementation
- Iron: haem and non-haem proteins/enzymes; requirements in growth, menstruation, pregnancy; iron-deficiency anaemia; fortification; excess/toxicity - iron overload; iron as a pro-oxidant
- Zinc: metalloproteins; transporters; effects of deficiency; immune effects; clinical importance
- Selenium: selenoproteins and their functions; redox/antioxidant effects; health effects of deficiency and marginal adequacy e.g. immunity; viral virulence; HIV; fertility/reproduction; cancer risk; current UK selenium status; excess/toxicity - selenosis
- Iodine: thyroid hormones, interaction with selenium; Iodine Deficiency Diseases (IDD) - goitre, cretinism, endemic retardation; prevention and control of IDD; goitrogens
- Other trace elements of nutritional importance
- Electrolytes: potassium, sodium, blood pressure
- Magnesium and calcium: deficiency; molecular and clinical roles.

Assessment Strategy
The assessment strategy is designed to provide students with the opportunity to demonstrate their knowledge and, where appropriate, the application of knowledge in practical settings (for example at the trace-element dinner during the module). The ability to be critical and the use of evidence to support the case or argument offered is assessed.
The summative assessment for this module consists of:
- Coursework: a range of subject areas will be assessed, demonstrating learning outcomes across the range for the module.
- Students are required to submit electronically on a deadline set two months following the end of the module.
Formative assessment and feedback
Students will receive feedback electronically in SurreyLearn and Module Organisers will be available for further discussion if necessary.
Module aims
- To give participants an understanding of the important roles played by dietary minerals in human metabolism and health.
- To discuss the range of requirements conventionally accepted for dietary minerals and factors that may alter these requirements.
- To ensure that students have a full understanding of how to assess trace element status and knowledge of the pitfalls involved in such assessment.
- To give participants knowledge of dietary sources of minerals and an understanding of factors affecting their bioavailability, including interactions with each other and with other nutrients.
- To explore in detail the symptoms of overt deficiency states and the less-apparent effects of marginal deficiency of essential minerals.
- To make participants aware of toxicity and other adverse consequences associated with an excess of minerals.
- To ensure that they are aware of genetic factors and acute conditions that can affect essential-trace-element levels.
- To discuss indications for appropriate supplementation or fortification.

Methods of Teaching / Learning
The learning and teaching strategy is designed to be aligned with the descriptor for qualification at level 7 in the Framework for Higher Education Qualifications (FHEQ) produced by the Quality Assurance Agency (QAA)
The learning and teaching methods include:
- Lectures (22.5 hours)
- Workshops
- Journal club
- Class discussions
Trace element dinner (3hr, as part of 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.
