Level 5 Nutrition and Immunity

Gain an in-depth understanding of how the immune system works and how dietary patterns and specific foods can be used to support its optimum functioning.

The components of the immune system and how they function.
This topic introduces the cells, tissues and organs of the immune system and explains how they function to prevent infection and disease. You will explore the different types of immunity such as innate and acquired and how factors such as ageing can affect our immune function. You will also learn about what happens when the immune system fails to function correctly, including immunodeficiency and autoimmune disorders.

Gut health and immunity
In recent years, the growing understanding of the fundamental role of gut bacteria in the regulation of the immune system has revolutionised the field of immunology. You will discover how diet, including prebiotic and probiotic foods, can support the balance of your gut bacteria. You will also learn about factors affecting the permeability of the intestine and the development and potential consequences of ‘leaky gut’ syndrome.

Micronutrients and immune function
A diet rich in vitamins and minerals is important for many aspects of health including immune function. You will learn about the specific roles that micronutrients and antioxidants play in the immune system and explore the potential impact of micronutrient deficiency on the risk of infectious and non-infectious diseases. You will also explore whether the use of vitamin and mineral supplements can be beneficial in preventing viral infections such as cold and flu

.
Diet and auto-immune conditions
Auto-immune conditions such as rheumatoid arthritis, inflammatory bowel disease, multiple sclerosis and allergies are increasingly common. You will learn how diet is implicated in the development of some auto-immune conditions. You will also learn about the evidence supporting the effectiveness of different dietary approaches in managing the symptoms of auto-immune conditions.

Dietary practices associated with optimum immune function.
You will discover what dietary practices are associated with optimal immune function. Diets low in processed foods and higher in antioxidants, Omega-3 fatty acids, and certain herbs and spices have all been reported to support better immune function. You will also explore the potential benefits of anti-inflammatory diets for the prevention and management of certain chronic health conditions such as cancer and Alzheimer’s disease.
