Nutrition & Immune Health

Dr Philip Calder opens with an overview of the human immune system, including the balancing concepts of immune tolerance and immune activation. He explains the role of nutrition in supporting immune system function and helping improve response to infection, while also highlighting the negative impact of micronutrient deficiency on immune function in several clinical studies. He closes with discussion of the gut-associated lymphoid tissue (GALT) and how it samples food and microbe antigens from the gut lumen.
