Digestive Disorders Course

What you will learn:

  • The structure of digestive system, function and organs, enzymes in digestion, the types of dietary carbohydrates, fats/oils and proteins as well as some of the common pathologies and how to identify and treat them.
  • The concept of energy expenditure and the factors which impact on this, the factors affecting energy intake, energy expenditure and the bodily mechanisms which control food intake, sources of food toxins, possible food safety concerns including adverse reactions to food, the “farm to fork” regulations, the correct procedures for food storage and the effects of a variety of cooking techniques on nutrient content.
  • The role of the gastrointestinal tract in detoxification, the scope of nutritional therapy in the support of gastrointestinal health, functions of the gastrointestinal tract as well as the importance of referral with ‘Red Flag’ symptoms.

Digestive Disorders Syllabus:

  • Main organs, basic structure and main function of the digestive tract

      2. Regulatory aspects affecting food production incl. FAO/WHO model food law
      3. Nutritional aspects of food policy – supply and demand; changing properties of foods e.g. fortification; international work on food policy
