Description for 2022/23

This module will focus on understanding the essential components of our diet and discuss the changes in nutrition and energy balance that the human body encounters through development from birth to adulthood. The module will address the need for the body to adapt nutrition to meet its energy requirements during sports and exercise. It will discuss the consequences of dietary imbalances on human health and how nutrition and diet can contribute to many Lifestyle disorders including obesity related disorders, coronary heart disease, glucose intolerance and diabetes. This module aims to provide an informed, research based understanding of nutrition, diet and energy balance on human health, by integrating aspects of physiology, biochemistry, food science and exercise physiology.
This module will offer a number of laboratory based practical opportunities, including a visit to the Anatomy Suite at the Medical School to learn about the digestive system and also an Exercise Physiology practical to understand energy requirements during exercise. In addition, the lectures in this module will be complemented with guest lectures to highlight our current thinking in human nutrition and health. Ethical issues that concern diet and nutrition will be discussed in tutorials.
Indicative Contents
This module is taught through a combination of lectures and laboratory sessions as well as tutorials and private study, combined with on line support and readings from relevant text books.
Lectures:
Nutrition and energy balance; energy and organic macromolecules (fats, carbohydrates and proteins); absorption and functions of vitamins and minerals; alcohol; regulation of food intake: Hunger and satiety; positive energy balance and obesity; the role of nutrition in the development and management of cardiovascular diseases; nutrition and cancer; sport nutrition; nutrition and the human life course and nutrition in mental health.
Practicals:
Physiology of digestive tract; food digestion; calculating energy balances; estimating body composition; a critical appraisal of weight management strategies.
Tutorial:
Ethical argument and discussion

Aims
The study of human nutrition was once focused on understanding the essential components of our diet and the consequences of dietary deficiencies on human health. It is now recognised that in western societies at least, dietary excesses contribute to a clutch of inter-related disorders known as the metabolic syndrome which include obesity related disorders, coronary heart disease, glucose intolerance and diabetes. The recognition that imbalances in our diet can be a contributory factor in these disorders as well as other diseases such as breast cancer is leading to improved public understanding of the interrelationship between diet and health, and a popular move towards healthy eating. This module aims to provide an informed, research based understanding of nutrition, diet and energy balance on human health, by integrating aspects of physiology, biochemistry, food science and exercise physiology.

Intended Learning Outcomes

Identify the principal components of a balanced diet and how they are digested, absorbed and metabolised in a healthy adult with reference to underlying research and dietary principles: 1
Discuss current concepts of how nutritional requirements of humans differ with age: 1
Describe how energy balance can be adjusted through dietary formulations and exercise and the limits of such adjustments: 1,3
With reference to current knowledge and its potential limitations, explain the physiological adaptations that occur during prolonged physical exercise (training) and the special nutritional requirements that might improve athletic performance: 3

Description of Module Assessment

1: Open Book Examination weighted 65%
Online Open Book Exam
The paper will be released on KLE as a Word document at 9am on the morning of the exam. The paper will contain a choice of two out of four essay based questions. Students should answer each question using Word, clearly labelling each question as they provide their answers. Work will be submitted to Turnitin no later than 5pm on the day of release. International students will be asked to notify the School if they need an extension due to different time zones. Although students have been given significant time to complete this exam script, we expect most students to spend no more than 2 hours. Answers should be as accurate and concise as possible. For short-answer questions, students should pay careful attention to the number of points that each question is worth. In general, we would expect only one or two sentences for each point. For essay-based questions, typical answers would be in the range of 500-750 words per question. We recommend that students do not exceed 750 words per essay-based question as we will be assessing the quality of your answer, not the quantity.

2: Essay weighted 15%
Short 1000 word essay
Students will write a short essay on an ethical argument concerning diet and nutrition.

3: Essay weighted 20%
Essay
Students will write an essay on nutrition and exercise performance with a word limit of 1500.
