Key Points:

Immune health is supported by a well-balanced diet rich in fruits and vegetables, which provide essential nutrients like vitamins, minerals, fiber, water, and phytonutrients that help the body fight bacteria and viruses.
Water is crucial for immune function as it aids in detoxification and maintains healthy protective tissues that serve as the body's first defense against pathogens.
Fiber, especially soluble fiber found in whole fruits and vegetables, supports the gut microbiome, which plays a key role in immune modulation and overall health.
Key vitamins (A, B6, C, D, E) and minerals (zinc, iron, selenium) found in produce act as antioxidants and support immune cell function, reducing inflammation and oxidative stress.
