To practice nutrition in medicine, it is essential to have a basic understanding of the biochemistry, physiology and pathophysiology of nutrients, the derivation and sources of recommended daily nutrient intakes (called Dietary Reference Intakes in Canada and the USA) and approaches to nutritional assessment. Many nutrients may have adverse effects if overconsumed – thus “more is not always better” - so there recommended upper intake levels of some nutrients have been set to prevent adverse health effects. The recommended ranges of intakes of essential nutrients are part of the Dietary Reference Intakes.
By the end of the gastrointestinal and nutrition subunit you should have covered the following areas and be able to perform the tasks outlined in this list:
Themes
Tutorial Cases
Anatomy
Activities
The Gastroenterology concepts include the physiology and pathophysiology of digestion, absorption and metabolism of macronutrients and micronutrients, the structure and function of the hepatobiliary system, gastrointestinal tract integrity and gastrointestinal autoimmunity. Additionally, these concepts provide an introduction to understanding the common disorders of the gastrointestinal tract and the hepatobiliary system. During this Foundation you will develop an understanding of the important elements of the structure and functional relationships in the gastrointestinal tract. By the end of the Foundation, you should have an understanding of the significance of the cardinal manifestations of gastrointestinal disorders.
During the past decade, rapid expansion in a number of relevant scientific fields and, in particular, in the amount of population-based epidemiological evidence has helped to clarify the role of diet in preventing and controlling morbidity and premature mortality resulting from noncommunicable diseases (NCDs). Dietary practices likely play a major role in 7/10 top causes of disease and death including: heart disease, obesity, diabetes, osteoporosis and certain cancers. The mechanisms of the chronic disease process are clearer, and interventions have been demonstrated to reduce risk. In MF3, the overall objective is to learn normal nutrition and metabolism and to begin to understand the role of diet and specific nutrients and bioactive components of foods in disease prevention and treatment, and some of the major research that underlies dietary recommendations.
