How the Immune System Works
Your immune system serves as your body’s defense, distinguishing healthy cells from harmful invaders. It involves a complex network of organs, proteins, and cells that work together to respond to pathogens, sending white blood cells to combat threats.
Supporting your immune system with a balanced diet is particularly important for individuals with compromised immunity, such as those with autoimmune diseases or undergoing chemotherapy.
By incorporating these nutrient-dense foods into your diet, you can enhance your immune function and overall health.
