Strengthening Immune System: Role of Nutrients and Dietary Components

The immune system protects the human body against harmful microbes such as bacteria, viruses, and also against parasites. It is composed of a network of intricate stages and pathways in the body. Several factors including older age, environmental toxins, excess weight, poor diet and chronic diseases can weaken the immune system. Malnutrition or poor diet can potentially impair the production and activity of immune cells and antibodies. The immune system of a body relies on the presence of many micronutrients such as vitamin C, vitamin D, zinc, selenium, iron and proteins. They are essential for the growth and function of immune cells. Therefore, it is crucial to consume a balanced diet containing a sufficient amount of nutrients for ensuring the efficient functioning of the human body. This book outlines the role of nutrients and dietary components in strengthening the immune system in detail. It aims to equip students and experts with the advanced topics and upcoming concepts in this area of study.
